Turmeric Extract

Kurkuma-Extrakt

Curcuma longa

Turmeric extract (from Curcuma longa rhizomes) is a concentrated botanical source of polyphenolic curcuminoids and volatile turmerone oils widely used as a dietary supplement for joint, metabolic and cognitive support. Standardized extracts commonly report up to <strong>95% total curcuminoids</strong> and are formulated in multiple delivery forms (phytosomes, piperine complexes, micelles) because unformulated curcumin has <strong>&lt;1% systemic oral bioavailability</strong>. Clinical trials and meta-analyses show consistent, moderate evidence for symptom relief in knee osteoarthritis and modest biomarker improvements in metabolic syndrome and systemic inflammation when therapeutic formulations and adequate dosing (typically <strong>500–2000 mg curcuminoids/day</strong> for conventional extracts) are used. Turmeric extracts are generally well tolerated; the most common adverse effects are gastrointestinal (<strong>2–10%</strong> depending on dose/formulation). Important safety considerations include potential interactions with anticoagulants, CYP/UGT-metabolized drugs and iron supplements, and pregnancy/lactation caution. This article provides an evidence-oriented, FDA/NIH-focused, practical guide to identification, mechanisms, clinical benefits, dosing, interactions and product selection for US consumers and clinicians.

Curcumin C3 Complex

Curcumin C3 Komplex

Curcuma longa curcuminoids

Curcumin C3 Complex is a clinically used, research-grade turmeric extract standardized to the three primary curcuminoids (curcumin, demethoxycurcumin, bisdemethoxycurcumin). This premium encyclopedia entry synthesizes chemical identity, pharmacology, pharmacokinetics, mechanisms of action, clinical benefits, dosing guidance, formulation comparisons, safety, drug interactions, regulatory context for the US market, and practical product-selection criteria. The article uses the supplied primary ingredient dossier as the source of scientific facts and provides an actionable, evidence-based roadmap for clinicians, formulators, and informed consumers. Key practical conclusions: typical standardized daily doses range from 250 to 1,500 mg of curcuminoids; oral bioavailability of unformulated C3 Complex is very low (<1%); enhanced formulations (piperine, phytosome, nanoparticle/micellar) raise plasma exposure multiple-fold but increase interaction risk; common clinical applications with medium evidence include osteoarthritis symptom reduction, improvements in inflammatory biomarkers, metabolic parameter support, and adjunctive mood benefit. This summary is US-focused (FDA/NIH context), identifies quality-selection checkpoints, and flags populations where caution or medical supervision is required.

Ashwagandha Root Extract

Ashwagandha-Wurzelextrakt

Withania somnifera

Ashwagandha Root Extract — derived from the dried roots of <em>Withania somnifera</em> (Solanaceae) — is one of the most extensively researched adaptogenic herbs in modern nutritional science, with a pharmacological legacy spanning over 3,000 years of Ayurvedic medicine. Its primary bioactive constituents, the withanolides (steroidal lactones including Withaferin A, C₂₈H₃₈O₆, CAS 5119-48-2), exert multi-target effects on the hypothalamic–pituitary–adrenal (HPA) axis, NF-κB inflammatory signaling, Nrf2 antioxidant pathways, and GABAergic neurotransmission. Clinically, standardized root extracts (typically 300–600 mg/day standardized to 5% withanolides) have demonstrated statistically significant reductions in serum cortisol, improvements in validated stress and anxiety scores, enhanced sleep quality, increased testosterone in men, measurable gains in muscle strength, and modest cognitive benefits — all supported by randomized controlled trials. Regulated in the United States as a dietary supplement under DSHEA, it is available from reputable brands (KSM-66, Sensoril, Thorne, NOW Foods) at price points ranging from $15 to $100+ per month. Generally well tolerated at standard doses, with a side-effect incidence below 5%, Ashwagandha Root Extract stands as one of the most evidence-supported botanical adaptogens for adults managing chronic stress, sleep disruption, or performance optimization.

Ginseng Root Extract (Panax)

Ginseng-Wurzelextrakt (Panax)

Panax ginseng

Panax ginseng root extract is a standardized herbal nutraceutical derived from the dried root of Panax ginseng C.A.Mey. — a triterpene saponin (ginsenoside)-rich adaptogen used for millennia in East Asian medicine. Modern standardized extracts typically contain <strong>2%–10% total ginsenosides</strong> and are formulated as capsules, tablets, liquid extracts or fermented/enzyme-processed concentrates intended to increase the oral bioavailability of deglycosylated metabolites (e.g., compound K). Clinical applications supported by moderate evidence include reduction of fatigue, modest cognitive enhancement, immune modulation and improvement in mild erectile dysfunction; metabolic and exercise performance outcomes show mixed but biologically plausible effects. Oral bioavailability of intact major ginsenosides is generally low (<5%); gut microbiota conversion to smaller, more lipophilic metabolites strongly determines systemic exposure. Typical standardized clinical dosing ranges from <strong>200–400 mg/day</strong> for general wellness up to <strong>600–900 mg/day</strong> in trials of erectile function, while whole-root doses of <strong>1–3 g/day</strong> are commonly used in metabolic studies. Users should monitor for interactions (notably with warfarin and antidiabetics), avoid use in pregnancy/lactation without medical advice, and select products with third-party Certificates of Analysis and ginsenoside standardization.

Rhodiola Rosea Extract

Rosenwurz-Extrakt

Rhodiola rosea

Rhodiola rosea extract is a standardized botanical adaptogen derived from the dried root and rhizome of <em>Rhodiola rosea</em> L. (family Crassulaceae), a perennial plant native to the Arctic, Siberia, Scandinavia, and high-altitude regions of Europe and Asia. Commercially standardized to 3% rosavins and 1% salidroside — its two principal bioactive marker compounds — Rhodiola has been used for centuries in traditional Arctic and Tibetan medicine to combat fatigue, enhance physical endurance, and improve resistance to cold and altitude stress. Modern pharmacology classifies Rhodiola as an adaptogen: a non-specific stress-resistance enhancer that modulates the hypothalamic–pituitary–adrenal (HPA) axis, monoaminergic neurotransmission, and mitochondrial energy metabolism. Clinical trials support its use for reducing mental and physical fatigue, improving cognitive performance under stress, and alleviating mild-to-moderate depressive symptoms. The typical therapeutic dose ranges from 200–600 mg/day of standardized extract, taken in the morning. Rhodiola is generally well tolerated; the most common side effects — mild nervousness, insomnia, and gastrointestinal upset — affect fewer than 5% of users at standard doses. Regulated as a dietary supplement under DSHEA in the US, Rhodiola is widely available through retailers such as Amazon, iHerb, and Thorne Research.

Echinacea Purpurea Extract

Echinacea-Purpurea-Extrakt

Echinacea purpurea

Echinacea purpurea extract (purple coneflower extract) is a standardized botanical preparation derived from the aerial parts and/or roots of Echinacea purpurea. Rich in alkylamides, caffeic acid derivatives (notably cichoric acid), polysaccharides and flavonoids, E. purpurea extracts are widely used in the U.S. as dietary supplements for upper respiratory infection (URI) prevention and early treatment. Mechanisms supported by preclinical and clinical data include innate immune stimulation (macrophage and NK-cell activity), balanced immunomodulation via alkylamides acting at CB2-like receptors, anti-inflammatory effects through NF-κB/MAPK modulation and in vitro virucidal activity against some enveloped respiratory viruses. Clinical trials and meta-analyses show mixed but sometimes clinically meaningful reductions in cold incidence and symptom duration (typical reported reductions: <strong>~1–3 days</strong> when started at symptom onset in some trials). Typical adult dosing in randomized studies ranges from <strong>300–1,500 mg/day</strong> of standardized extract or tincture equivalents. Safety is generally good for short-term use; allergic reactions (Asteraceae-sensitive individuals) and theoretical interactions with immunosuppressants and CYP-metabolized drugs warrant caution. This article is a comprehensive, science-focused reference for clinicians, researchers and informed consumers in the U.S. market.

Saw Palmetto Extract

Sägepalmen-Extrakt

Serenoa repens

Saw palmetto extract (derived from the ripe berries of Serenoa repens) is a standardized lipid-rich botanical extract widely used by men to support lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH). Typical standardized dosing in clinical trials is 160 mg twice daily (total 320 mg/day) of a fatty-acid– and phytosterol-rich extract. Mechanistic research shows multifactorial activity — partial inhibition of 5α-reductase, anti-inflammatory effects (COX/5-LOX, NF-κB modulation), and mild smooth-muscle relaxation — that plausibly explains modest symptomatic improvements reported in some randomized trials. Safety at standard dosing is generally good; the most common adverse events are mild gastrointestinal complaints (nausea, diarrhea) occurring in approximately 1–8% of participants in clinical studies. Saw palmetto products differ markedly by extraction method (CO2 vs. ethanolic vs. cold-pressed) and standardization; for US consumers, prefer third-party tested CO2 or standardized lipid extracts with certificate-of-analysis and clear fatty-acid/sterol content. This article delivers a comprehensive, evidence-focused encyclopedia-level review tailored to the US market, including mechanisms, dosing, benefits, safety, drug interactions, quality criteria, and practical purchasing guidance.

Garlic Extract

Knoblauch-Extrakt

Allium sativum

Garlic extract (Allium sativum extract) is a sulfur-rich botanical nutraceutical used for millennia that contains unstable volatiles (allicin) and stable water-soluble organosulfur compounds (notably S‑allyl cysteine, SAC). Modern preparations range from raw/crushed garlic (allicin-forming) to aged garlic extract (AGE, SAC-rich, odorless) and garlic oil (DADS/DATS-rich). Clinical research supports modest, reproducible benefits for blood pressure (mean systolic reductions ~5–10 mmHg in several trials), modest LDL lowering, antiplatelet effects and reduced incidence/duration of common cold in some trials; effects are formulation- and dose-dependent. Typical supplemental dosing used in trials: 600–1,200 mg/day for aged garlic extract or 600–1,200 mg/day garlic powder (with allicin-standardized products delivering specific mg allicin/day). Garlic supplements are generally well tolerated but can increase bleeding risk when combined with anticoagulants/antiplatelet drugs and may interact with CYP3A4 substrates in formulation-dependent ways. This article provides a complete, science-focused, clinically actionable overview of chemistry, pharmacokinetics, mechanisms, benefits, dosing and safety for US clinicians and informed consumers.

Pinus pinaster

Pine bark extract (commonly standardized from Pinus pinaster and marketed as Pycnogenol-type extracts) is a proanthocyanidin-rich botanical nutraceutical used for microcirculatory support, endothelial function, antioxidant defense, and skin health. Standardized commercial extracts typically contain ~65–75% procyanidins and are dosed clinically at **50–300 mg/day**, with common regimens of **100–200 mg/day**. Clinical trials and mechanistic studies indicate benefits for chronic venous insufficiency (symptom and edema reduction), endothelial-dependent vasodilation, and reductions in oxidative and inflammatory biomarkers. Pine bark constituents include monomeric flavanols (catechin, epicatechin), low-molecular-weight oligomeric procyanidins (dimers/trimers), and phenolic acids; monomers have estimated oral bioavailability of **~20–40%**, while intact oligomers are absorbed at **<5–10%**, with substantial additional systemic exposure via microbiota-derived phenolic metabolites. Safety is generally good at common doses; main precautions include bleeding risk with anticoagulants and pregnancy/lactation avoidance due to limited data. This article is an in-depth, evidence-oriented, US-focused compendium for clinicians and informed consumers.

Elderberry Extract

Holunderextrakt

Sambucus nigra

Elderberry extract (from Sambucus nigra L.) is an anthocyanin-rich botanical supplement widely used for short-term support of upper respiratory symptoms. Modern products are typically standardized to total anthocyanins and formulated as syrups, powders/capsules, lozenges or tinctures. Clinical evidence from randomized trials indicates that early administration of standardized elderberry extract can reduce the duration of influenza-like illness symptoms by approximately 50% in small outpatient studies (e.g., 3–4 days vs. 7–8 days in Zakay‑Rones et al., 2004). Proper processing removes toxic cyanogenic glycosides present in raw plant parts; when manufactured and dosed correctly, elderberry extract is generally well tolerated, with gastrointestinal complaints and rare allergic reactions reported. Elderberry products in the U.S. are regulated as dietary supplements under DSHEA — manufacturers must follow cGMPs and avoid disease-treatment claims. For clinicians and consumers seeking evidence-based use, elderberry is best used early in acute uncomplicated URTIs at manufacturer-recommended, standardized doses and not as a replacement for indicated antiviral therapy in severe influenza or COVID-19. If you want a live, up-to-date list of 2020–2026 primary studies with PMIDs/DOIs, I can retrieve and append them on request.

Sambucol Black Elderberry

Sambucol Schwarzer Holunder

Sambucus nigra L.

Sambucol Black Elderberry (standardized Sambucus nigra L. fruit extract) is a commercially produced, anthocyanin-rich botanical supplement marketed for short-term relief of upper respiratory tract infection (URTI) symptoms and immune support. Sambucol preparations are standardized to total anthocyanin content (major constituents: cyanidin-3-glucoside and cyanidin-3-sambubioside), supplied as syrup, lozenges, tablets or capsules, and intended for early short-course dosing (typical adult protocol: 15 mL syrup q4–6h or equivalent extract 600–1500 mg/day for 3–5 days). Clinical trials and in vitro studies report reductions in URTI symptom duration (range: mean reduction ≈ 1–4 days) and severity when started within 24–48 hours of symptom onset. Safety data for processed, standardized extracts show mostly mild gastrointestinal adverse effects (<5%) and rare hypersensitivity; raw elderberry parts contain cyanogenic glycosides and are contraindicated. In the US Sambucol is sold as a dietary supplement (DSHEA) and is not FDA-approved to treat or prevent infectious disease; consumers should consult clinicians when using elderberry concurrently with anticoagulants or immunosuppressants.

Holy Basil Extract

Heiliges Basilikum-Extrakt

Ocimum tenuiflorum

Holy basil extract (Tulsi, Ocimum tenuiflorum) is a multi‑constituent Ayurvedic botanical used as an adaptogen, antioxidant, anti‑inflammatory, metabolic adjunct, and topical antimicrobial. Standardized extracts typically contain marker compounds such as eugenol, ursolic acid and rosmarinic acid and are formulated as teas, hydroalcoholic capsules (300–1200 mg/day commonly used in clinical trials), essential oils, and advanced lipid/phytosome preparations. Modern pharmacology implicates HPA‑axis modulation, NF‑κB inhibition, Nrf2 activation, AMPK/PPAR metabolic signaling, and direct antimicrobial membrane effects as core mechanisms. Safety is generally good at recommended doses but essential oils and high‑dose extracts carry risks (bleeding potentiation with anticoagulants, additive hypoglycemia, sedation). High‑quality large randomized controlled trials for many indications remain limited; targeted literature retrieval (PubMed) is recommended to compile up‑to‑date PMIDs/DOIs for specific clinical claims.

Cat's Claw Extract

Katzenkralle-Extrakt

Uncaria tomentosa

Cat's claw extract (Uncaria tomentosa) is a standardized botanical supplement derived from the bark and root of a woody Amazonian vine, used primarily for anti‑inflammatory and immunomodulatory purposes. Modern preparations are hydroalcoholic or aqueous extracts standardized to marker alkaloids (pentacyclic oxindole alkaloids) and polyphenols. Traditional Amazonian use predates scientific study; contemporary phytochemistry identifies indole/oxindole alkaloids (e.g., mitraphylline, isopteropodine), triterpenes and proanthocyanidins as putative active constituents. Mechanistic research — largely in vitro and in animals — indicates inhibition of NF‑κB signaling, modulation of cytokine production (TNF‑α, IL‑1β, IL‑6), antioxidant effects and modest effects on matrix metalloproteinases relevant to joint disease. Human clinical trials are limited, heterogeneous in extract chemistry and sample size, and show mixed results for osteoarthritis and inflammatory symptoms. Typical supplement dosing ranges from 250–750 mg/day of standardized extract (commonly 300–400 mg twice daily); safety concerns include potential interactions with immunosuppressants and anticoagulants, and limited pregnancy/breastfeeding data. Quality selection should prioritize species verification, standardized alkaloid content and third‑party testing (GMP, NSF, ConsumerLab).

Hops Extract

Hopfen-Extrakt

Humulus lupulus

Hops extract (from Humulus lupulus L.) is a botanical nutraceutical used primarily for sleep support and menopausal symptom relief. Standardized extracts concentrate hop prenylflavonoids (xanthohumol, isoxanthohumol, 8‑prenylnaringenin) and bitter acids (humulones, lupulones). Typical supplement doses range from 300–500 mg daily for sleep support and 250–500 mg daily for menopausal symptom trials; formulations and bioavailability vary widely. Clinically, hops have moderate evidence for improving sleep latency and sleep quality—often when combined with valerian—and preliminary human and robust preclinical evidence for estrogenic activity (mediated by 8‑PN), anti‑inflammatory properties (xanthohumol), and microbiome‑dependent metabolism. Safety considerations include sedation, potential interactions with CNS depressants, and avoidance in pregnancy or known hormone‑sensitive cancers. This premium, evidence‑focused guide describes chemistry, pharmacokinetics, mechanisms, clinical benefits, dosing, interactions, quality selection, and practical U.S. market guidance for clinicians and informed consumers.

Kava Kava Extract

Kava-Kava-Extrakt

Piper methysticum

Kava kava extract is a standardized botanical preparation made from the peeled roots and rhizomes of Piper methysticum, commonly used as an evidence-supported anxiolytic and mild sedative. Standardized extracts are typically expressed as percent total kavalactones and clinical trials for anxiety most often use daily intakes equivalent to approximately 120–250 mg total kavalactones. Kava displays polypharmacology: kavalactones modulate GABA-A receptor function, inhibit voltage-gated ion channels, and affect monoaminergic signaling. The principal safety concern is rare but serious hepatotoxicity reported in the 1990s–2000s, prompting regulatory scrutiny; modern best practices prioritize root-only, noble-cultivar sourcing, aqueous extraction, and third-party testing. For adults without liver disease who avoid alcohol and hepatotoxins, kava can be a short-term option for mild-to-moderate anxiety and stress-related sleep disturbances, using standardized products, divided dosing, and periodic liver monitoring. This premium guide synthesizes chemistry, pharmacokinetics, mechanisms, clinical evidence, dosing, interactions, quality criteria, and practical US-market advice for clinicians, formulators, and informed consumers.

Fenugreek Extract

Bockshornklee-Extrakt

Trigonella foenum-graecum

Fenugreek extract (from Trigonella foenum-graecum seed) is a multi-component botanical used as a nutraceutical for glycemic control, lactation support, lipid modulation, and digestive health. Clinical trials and mechanistic studies have focused on its soluble fiber (galactomannans), saponins (diosgenin-containing glycosides), the unusual branched amino acid 4-hydroxyisoleucine (4‑HIL), and the alkaloid trigonelline. Typical evidence-based dosing ranges from powdered seed 2–15 g/day to standardized extracts 300–1,000 mg/day. Fenugreek’s mechanisms include increased gastric/intestinal viscosity delaying carbohydrate absorption, glucose-dependent insulinotropic effects (4‑HIL), bile-acid binding by saponins reducing cholesterol absorption, and modest anti-inflammatory signaling modulation. Safety is generally good at recommended doses; main concerns are gastrointestinal effects, a characteristic maple-like odor, possible allergic cross-reactivity with legumes, and clinically relevant interactions with antidiabetic and anticoagulant drugs. This premium, clinician-oriented guide summarizes identification, chemistry, pharmacokinetics, mechanisms, 8+ evidence-based benefits, dosing, interactions, contraindications, product selection for the US market (FDA/NIH context), and practical consumer advice.

Horny Goat Weed Extract

Ziegenkraut-Extrakt

Epimedium species

Horny Goat Weed extract (Epimedium spp.) is a standardized botanical supplement commonly quantified by its marker flavonol glycoside, icariin (CAS 489-32-7). Used traditionally in Traditional Chinese Medicine for centuries, modern extracts (typical doses 250–1,000 mg/day standardized to 1–20% icariin) are marketed in the US for sexual health, bone support, endothelial function and mild fatigue. Oral bioavailability of the intact glycoside is low (<5–10% in preclinical models); systemic exposure is driven largely by gut microbial deglycosylation to aglycones (icariside II, icaritin). Safety in short-term use is acceptable for most healthy adults but interactions with nitrates, PDE5 inhibitors and anticoagulants are clinically important. High-quality randomized trials in humans are limited; product quality varies widely, so choose standardized extracts with third-party COA and GMP certification.

Shatavari Extract

Shatavari-Extrakt

Asparagus racemosus

Shatavari extract (from the dried roots of Asparagus racemosus) is a traditional Ayurvedic botanical used for millennia as a female reproductive tonic and adaptogen. Modern phytochemistry identifies a complex mix of steroidal saponins (notably shatavarins I–V), flavonoids, alkaloids (e.g., asparagamine A) and mucilaginous polysaccharides; standardized extracts are commonly expressed as % total steroidal saponins. Contemporary clinical use in the U.S. centers on lactation support (galactagogue), menstrual and menopausal symptom support, and adaptogenic/mood benefits. Typical standardized-extract supplement doses range from <strong>300–1,000 mg/day</strong>, while traditional decoctions use several grams of root powder daily. Safety data are limited but generally favorable: most reported adverse events are mild gastrointestinal complaints. Important cautions include theoretical estrogenic activity (avoid in estrogen-dependent cancers unless supervised), potential interactions with anticoagulants and drugs dependent on gut microbiota for metabolism, and limited pregnancy safety data.

This premium, evidence-focused dossier synthesizes ethnobotany, phytochemistry, pharmacology, safety, dosing and practical product selection for the US market. The extract contains labile volatile phthalides (notably ligustilide), phenolic acids (ferulic acid), coumarins and polysaccharides; extraction method (ethanol vs water) markedly alters constituent profile and likely clinical effects. Typical clinical dosing in supplements ranges from 500–3,000 mg/day depending on form and standardization; caution is required with anticoagulants, pregnancy, breastfeeding and hormone-sensitive conditions. Human pharmacokinetic data for whole extracts are limited; most PK knowledge is derived from constituent studies showing rapid absorption (Tmax often <2 hours), phase II conjugation and renal elimination of metabolites within 24–48 hours. Preclinical mechanisms plausibly include increased endothelial nitric oxide, antiplatelet activity, NF-kB downregulation and weak estrogen receptor modulation. High-quality randomized clinical trials are sparse and heterogeneous. This article provides practical US-centric guidance on formulation selection, quality criteria (COA, GMP, HPLC/GC-MS fingerprinting), and conservative clinical recommendations while noting where primary literature lookup is required for citation-level claims.

<p><strong>Wild yam extract (Dioscorea villosa rhizome extract) is a steroidal saponin–rich botanical used traditionally for colic and menstrual cramps; its principal chemical marker is <em>diosgenin</em> (CAS 512-04-9), a lipophilic spirostan sapogenin present mainly as glycosides such as <em>dioscin</em>.</strong> This 200-word summary explains composition, traditional uses, modern evidence, dosing ranges, safety, and product-selection guidance for U.S. consumers and clinicians. Wild yam is botanically classified in the family <em>Dioscoreaceae</em> and is commercialized as powdered roots, standardized extracts, tinctures, and topical creams. While diosgenin served as an industrial precursor for steroid synthesis in the 1930s (Marker process), there is no reliable evidence that ingestion or topical application of wild yam converts it into human progesterone in vivo. Most human clinical data are limited, and high-quality randomized controlled trials for menopausal symptoms, dysmenorrhea, metabolic or anticancer uses are lacking; the strongest mechanistic data derive from in vitro and animal studies showing NF-κB, MAPK and PI3K/Akt modulation. Typical consumer doses range from <strong>50–600 mg/day of extract</strong> with diosgenin-standardized products often providing <strong>~5–50 mg/day diosgenin</strong> depending on formulation. Use caution in pregnancy, breastfeeding, children, and with concomitant drugs (antidiabetics, CYP3A4 substrates, anticoagulants), and prefer third-party tested standardized extracts from reputable U.S. brands under DSHEA regulation.</p>

Taraxacum officinale

Dandelion root extract (Taraxacum officinale radix) is a multi-component botanical used traditionally as a bitter digestive, mild diuretic, choleretic, and prebiotic source of inulin. Modern preparations are aqueous decoctions, hydroalcoholic tinctures, powdered root and standardized extracts (commonly standardized to chicoric acid or inulin content). Pharmacology reflects a combination of non-absorbable fructans (inulin) that act as prebiotics and absorbable polyphenols (chicoric acid, chlorogenic acid, luteolin) and terpenes (taraxasterol, sesquiterpene lactones) that mediate antioxidant, anti-inflammatory, hepatoprotective and mild diuretic effects. Typical supplement doses range from <strong>300–1,000 mg/day</strong> for concentrated extracts and <strong>1–3 g/day</strong> for powdered root; prebiotic actions usually require higher isolated inulin doses (commonly 5–10 g/day). Safety profile is favorable at customary doses but includes rare Asteraceae allergies, mild GI upset (1–5%), and theoretical interactions with diuretics, lithium, anticoagulants and antidiabetic drugs. Robust human randomized controlled trials are limited; most mechanistic data derive from in vitro and animal studies with growing but still modest human observational/clinical evidence.

Oregon grape root extract (Mahonia aquifolium) is a botanical root/rhizome extract standardized by alkaloid markers (primarily berberine). Historically used by Indigenous North American peoples for topical skin infections and digestive complaints, modern preparations are sold in the US as dietary supplements and topical dermatologic products. Pharmacology is driven largely by isoquinoline alkaloids (berberine, palmatine, jatrorrhizine, berbamine) producing antimicrobial, anti‑inflammatory and metabolic effects (AMPK activation, LDLR upregulation). Oral systemic efficacy for glycemic and lipid endpoints is supported primarily by randomized trials of purified berberine (typical oral dosing 900–1500 mg/day divided), while topical Mahonia formulations (0.5–5% extracts) show medium-level evidence for improving mild-to-moderate psoriasis and acne. Safety: GI complaints are most common; avoid in pregnancy, breastfeeding, neonates, and with narrow‑therapeutic‑index drugs (warfarin, digoxin, immunosuppressants) because of CYP/P‑gp interactions. For US consumers, choose standardized extracts with third‑party Certificates of Analysis (HPLC berberine assay), GMP manufacture, and clear labeling.

Barberry Extract

Berberitzen-Extrakt

Berberis vulgaris

Barberry extract (primarily standardized for the alkaloid berberine) is a plant-derived nutraceutical extensively researched for metabolic health. Multiple randomized trials and meta-analyses report clinically meaningful reductions in fasting glucose (typically <strong>~10–20%</strong> relative declines in glycemic endpoints) and LDL-cholesterol (typically <strong>~10–25%</strong>) after 8–12 weeks at standard trial dosages (commonly <strong>900–1500 mg/day</strong> berberine-equivalent).

Bitter Melon Extract

Bittermelonen-Extrakt

Momordica charantia

Bitter Melon Extract (Momordica charantia) is a botanical dietary supplement used worldwide for metabolic support. Extensive preclinical data identify multiple active classes — cucurbitane-type triterpenoids, steroidal glycosides (commonly measured as “charantin”) and insulin‑like peptides — that act via AMPK activation, reduced hepatic gluconeogenesis, improved peripheral glucose uptake and intestinal alpha‑glucosidase inhibition. Clinical trials are heterogeneous but several randomized and controlled studies report modest reductions in fasting plasma glucose (mean reductions commonly in the range of <strong>10–30 mg/dL</strong>) and small decreases in HbA1c over 8–12 weeks when standardized extracts (commonly <strong>1,000–2,000 mg/day</strong>) are used as adjuncts. Safety signals include dose‑dependent gastrointestinal effects and risk of additive hypoglycemia when combined with antidiabetic drugs; pregnancy is a contraindication. Consumers in the U.S. should prefer GMP‑manufactured, third‑party tested, standardized hydroalcoholic extracts and consult clinicians if taking prescription hypoglycemic agents.

Banaba Leaf Extract

Banaba-Blattextrakt

Lagerstroemia speciosa

<p><strong>Banaba leaf extract (Lagerstroemia speciosa) is a traditional Southeast Asian botanical standardized commonly to <em>corosolic acid</em> at 1–3% or to total ellagitannin content, and is used primarily for glycemic support.</strong> This 200-word summary explains origins, chemistry, mechanisms and practical usage for US consumers. Banaba leaves contain lipophilic pentacyclic triterpenes (notably corosolic acid, C30H48O4) and hydrophilic polyphenols (ellagitannins, gallic acid derivatives). Traditional aqueous decoctions are still used, while contemporary supplements come as standardized hydroalcoholic extracts, powders, tinctures and isolated corosolic acid formulations. Mechanistically, banaba acts via dual modalities: (1) intestinal <em>α‑glucosidase/α‑amylase</em> inhibition by tannins (reducing postprandial glucose absorption) and (2) peripheral insulin‑signaling enhancement (corosolic acid potentiates insulin receptor phosphorylation, PI3K/Akt signaling and GLUT4 translocation; may inhibit PTP1B). Typical commercial doses range from <strong>40–500 mg/day</strong>, often <strong>125–300 mg/day</strong> for glycemic support when standardized. Safety: generally well tolerated; main risks are gastrointestinal upset and pharmacodynamic hypoglycemia when combined with glucose‑lowering drugs. Quality varies — choose GMP-made, lot‑specific Certificates of Analysis showing corosolic acid or tannin assays and heavy‑metal/microbial screens. This guide provides an evidence‑focused, clinical‑style encyclopedia on banaba targeted to US prescribers, formulators and informed consumers.

Forskolin Extract

Forskolin-Extrakt

Coleus forskohlii diterpene

Forskolin extract (from Coleus forskohlii) is a plant-derived labdane diterpenoid that directly activates mammalian adenylyl cyclase to raise intracellular cAMP. Used historically in Ayurvedic medicine and widely as a research reagent since the 1980s, forskolin is marketed in the US as a standardized root extract (commonly 10–20% forskolin) for niche applications: body composition support, bronchodilation adjuncts (investigational), intraocular pressure research, and general metabolic modulation. Forskolin is lipophilic, poorly water soluble, and variably absorbed after oral dosing; typical supplement regimens deliver ~25–100 mg/day of pure forskolin depending on extract standardization and formulation. Clinical evidence for metabolic or weight-loss benefits is inconsistent and limited by small trials; mechanistically, forskolin’s robust biochemical effect is well established: direct activation of adenylyl cyclase → ↑cAMP → activation of PKA/EPAC → downstream effects on lipolysis, smooth muscle relaxation, platelet function, and gene transcription. Safety concerns focus on vasodilatory effects (hypotension), interactions (anticoagulants, antihypertensives, PDE inhibitors, β-agonists), and limited pregnancy/breastfeeding data. This premium article synthesizes chemistry, mechanisms, pharmacokinetics, evidence, dosing practices, drug interactions, and US-market quality guidance.

African Mango Extract

Afrikanischer-Mango-Extrakt

Irvingia gabonensis

African mango extract (Irvingia gabonensis kernel extract) is a botanical nutraceutical derived from the seeds (kernels) of the West/Central African bush mango. Commercial extracts — including proprietary preparations such as IGOB131 — combine a viscous soluble-fiber fraction (galactomannans), seed oil (rich in oleic and palmitic acids), proteins, and polyphenols. Clinical research (primarily mid-2000s–2013) reports modest, short-term improvements in body weight, waist circumference and some lipid and glycemic markers when extracts (commonly **300–700 mg/day**) are used adjunctively with diet. Mechanisms are mixed: local gastrointestinal effects of viscous fiber (delayed gastric emptying, reduced macronutrient absorption), plus adipocyte-level modulation (downregulation of PPARγ/C/EBPα, reduced adipogenesis, increased lipolysis) and favorable changes in adipokines. Safety in short-term trials is acceptable; most adverse events are mild gastrointestinal complaints. Long-term (>12 months) safety and independent large RCT data are limited. This article provides a comprehensive, evidence-focused synthesis, practical dosing guidance, drug-interaction precautions (notably with antidiabetic drugs and drugs with absorption sensitive to fiber), and US-specific quality-selection tips.

Hoodia Gordonii Extract

Hoodia-Gordonii-Extrakt

Hoodia gordonii

Hoodia gordonii extract is a standardized botanical preparation derived from a slow-growing succulent native to southern Africa, historically used by San peoples as a short‑term appetite suppressant. Modern commercial extracts are concentrated for pregnane glycoside content (commonly referenced as “P57” equivalents) and marketed for appetite control and weight‑management adjuncts. Scientific and regulatory scrutiny since the early 2000s revealed limited high‑quality clinical evidence for meaningful long‑term weight loss, frequent product quality concerns (adulteration and mislabeling), and unresolved pharmacokinetics in humans. Reputable selection requires certificates of analysis (HPLC/LC‑MS for pregnane glycosides), third‑party testing (NSF/ConsumerLab), and GMP manufacturing. Clinicians and consumers should treat Hoodia as an evidence‑limited supplement: potential for mild gastrointestinal adverse effects is documented, while serious cardiovascular events are more commonly linked to adulterated products. If considered, conservative short‑term use (weeks) with medical supervision, attention to product testing, and monitoring of blood pressure and glucose in at‑risk patients is recommended.

Cayenne Pepper Extract

Cayennepfeffer-Extrakt

Capsicum annuum

Cayenne pepper extract (standardized capsaicinoids) is a spice-derived botanical nutraceutical most notable for its principal active alkaloid, capsaicin (molecular formula <code>C18H27NO3</code>). <strong>Typical commercial oral supplements provide between <em>0.5–10 mg</em> capsaicin-equivalents per day, while topical formulations range from <em>0.025%–0.075%</em> (OTC) to an <em>8% prescription patch</em> used in clinics.</strong> This extract acts primarily through the TRPV1 receptor on sensory neurons to produce immediate nociceptive signaling followed by desensitization, and systemically it can increase sympathetic tone and thermogenesis. Clinical use divides into two validated areas: (1) localized neuropathic pain relief with high‑concentration topical capsaicin (single 8% patch applications providing weeks–months of analgesia) and (2) modest oral thermogenic/appetite-modulating effects for weight-management adjunctive use. Common side effects include transient topical burning and gastrointestinal upset with oral use; serious systemic toxicity from nutraceutical dosing is uncommon. Consumers in the U.S. should select standardized extracts (HPLC-verified capsaicinoid content), prefer lipid-based softgels for oral bioavailability, avoid inhaling powdered extracts, and consult healthcare providers when using anticoagulants, drugs with narrow therapeutic windows, or managing GI/respiratory disease.

Resveratrol (Japanese Knotweed)

Resveratrol (Japanischer Staudenknöterich)

Polygonum cuspidatum

Resveratrol (principally sourced from Polygonum cuspidatum, Japanese knotweed) is a plant-derived stilbenoid polyphenol (IUPAC: 5-[(E)-2-(4-hydroxyphenyl)ethenyl]benzene-1,3-diol; CAS 501-36-0) widely used as a nutraceutical for cardiovascular, metabolic and anti‑inflammatory support. Commercial supplements typically supply the biologically active <strong>trans‑resveratrol</strong> isomer; standard consumer doses range from <strong>150–500 mg/day</strong>, while clinical trials have explored <strong>50 mg to 2,000+ mg/day</strong). Resveratrol has strong preclinical evidence for activation/modulation of <em>SIRT1</em>, <em>AMPK</em> and <em>Nrf2</em> pathways, and human trials show modest improvements in endothelial function, triglycerides and some inflammatory biomarkers. Oral bioavailability of the unchanged parent molecule is very low (<strong>&lt;1% typical</strong>) due to rapid intestinal/hepatic glucuronidation and sulfation; therefore, micronized, lipid-based and complexed formulations or co‑administration with bioenhancers (piperine, quercetin) are used to improve systemic exposure. Safety is generally good at typical doses, but higher doses (>1 g/day) increase gastrointestinal complaints and may potentiate bleeding when combined with anticoagulants.

Rutin extract (quercetin-3-O-rutinoside) is a plant-derived flavonol glycoside widely used as a nutraceutical for vascular support, antioxidant activity, and microcirculation health. Chemically identified as C27H30O16, rutin is most commonly sourced from Sophora japonica and buckwheat and is marketed in powder, capsule, phytosome, and topical forms. Typical supplemental doses range from 250–500 mg/day for general antioxidant and capillary support and up to 500–1,000 mg/day for clinical venous symptom protocols. Rutin itself has low oral bioavailability as the intact glycoside (<10% as parent compound), and systemic exposure primarily reflects deglycosylation to quercetin and subsequent glucuronide/sulfate/methyl conjugates. Clinical literature supports modest benefits in chronic venous insufficiency, capillary fragility, and biomarkers of oxidative stress; preclinical evidence supports anti-inflammatory, endothelial-protective and neuroprotective mechanisms. Rutin is generally well tolerated; main precautions include potential additive bleeding risk with anticoagulants, reduced iron absorption via chelation, and uncertainty in pregnancy/breastfeeding.

Noni Extract

Noni-Extrakt

Morinda citrifolia

Noni extract (Morinda citrifolia) is a multi-component botanical derived from the ripe fruit (and sometimes leaves/roots) traditionally used across Polynesia and Southeast Asia for wound care, pain, and general tonic effects. Modern commercial preparations include fresh or fermented juice, pasteurized juice, spray‑dried powders, and standardized hydroalcoholic extracts. Noni contains diverse phytochemical classes — iridoid glycosides (asperulosidic acid), coumarins (scopoletin), anthraquinones (damnacanthal), flavonoids, polysaccharides and fatty acids — which together show antioxidant, anti‑inflammatory, immunomodulatory and cytoprotective activities in preclinical models. Human clinical evidence is limited and heterogeneous; safety signals include rare idiosyncratic hepatotoxicity reports and the potential for hyperkalemia in patients with renal impairment or on potassium‑sparing drugs. Quality varies widely across products; prefer third‑party tested, GMP‑made standardized extracts or pasteurized juices with Certificate of Analysis. This article syntheses chemistry, mechanisms, PK caveats, evidence levels, dosing guidance, drug interactions, contraindications, and practical selection tips for the US market. Note: I currently do not have live PubMed access in this session to fetch or verify PMIDs/DOIs for recent (2020–2026) trials; a follow‑up literature retrieval can be performed on request to add verified study citations.

Triphala Extract

Triphala-Extrakt

Emblica/Terminalia blend

Triphala Extract is a traditional Ayurvedic polyherbal extract composed of three dried fruits — Emblica officinalis (Amla), Terminalia bellirica (Bibhitaki) and Terminalia chebula (Haritaki) — traditionally blended in a 1:1:1 ratio and formulated today as powders, aqueous or hydroalcoholic standardized extracts, capsules and topical oral rinses. Modern phytochemistry identifies vitamin C, gallic and ellagic acids, chebulinic/chebulagic tannins and flavonoids as principal actives. Preclinical data indicate antioxidant, anti-inflammatory, antimicrobial and gut-microbiome-modulating activities; small human trials support topical oral benefits (gingivitis/plaque) and modest improvements in bowel regularity and metabolic markers. Typical supplemental dosing ranges from 250–1500 mg/day for standardized extracts, while traditional powdered bedtime doses for laxative effect are 1–3 g. Triphala may reduce iron absorption and can interact pharmacodynamically with anticoagulants and antidiabetics; it is generally well tolerated but can cause dose-dependent gastrointestinal symptoms. This article provides an evidence-focused, clinically oriented, US-centric encyclopedia guide including chemistry, pharmacokinetics, mechanisms, benefits, dosing, interactions, quality criteria and practical consumer advice.

Mucuna Pruriens Extract

Mucuna-Pruriens-Extrakt

Mucuna pruriens

Mucuna pruriens extract (velvet bean) is a seed-derived herbal supplement notable for its content of the dopamine precursor L‑3,4‑dihydroxyphenylalanine (L‑DOPA), which can comprise approximately <strong>1–7%</strong> of raw seed weight and up to higher percentages in standardized extracts. This encyclopedia‑level guide synthesizes botanical identification, chemistry, pharmacokinetics, molecular mechanisms, evidence‑based clinical benefits (Parkinsonian motor improvement, male fertility, mood/drive, antioxidant/neuroprotective potential), safety, drug interactions, dosing guidance and US‑market quality criteria. The article emphasizes clinical context: plant‑sourced L‑DOPA has pharmacology comparable to pharmaceutical levodopa but differs in purity, formulation, and the absence of routinely co‑formulated peripheral aromatic L‑amino acid decarboxylase (AADC) inhibitors such as carbidopa. Consumers and clinicians should treat standardized Mucuna extracts as pharmacologically active supplements, verify Certificates of Analysis (CoA) for L‑DOPA content and contaminant testing, and consult prescribers before use—especially if taking MAO inhibitors, antipsychotics, antihypertensives, anticoagulants, or iron supplements. This concise summary is followed by a complete, richly formatted 1,800–2,300 word HTML article with practical US‑focused recommendations, product selection guidance (USP/NSF/ConsumerLab considerations) and a structured FAQ.

Moringa Leaf Extract

Moringa-Blattextrakt

Moringa oleifera

Moringa leaf extract is a standardized botanical nutraceutical derived from the dried leaves of Moringa oleifera. Rich in flavonoids (quercetin, kaempferol), phenolic acids (chlorogenic acid), glucosinolates (glucomoringin) and isothiocyanates (moringin), it combines concentrated antioxidant, anti-inflammatory and metabolic-support activities with a nutrient-dense profile (vitamins A, C, E; calcium, iron, potassium). Modern preparations range from whole-leaf powder (1–6 g/day) to hydroalcoholic or isothiocyanate-enriched standardized extracts (commonly 300–600 mg/day). Clinical studies show medium-level evidence for modest improvements in fasting glucose, lipids and inflammatory biomarkers over 4–12 weeks when quality-controlled leaf extracts are used as adjuncts. Safety is good for leaf preparations at customary doses but root/bark parts are contraindicated in pregnancy. Quality selection should prioritize clear botanical identification, third-party Certificates of Analysis (heavy metals, microbes), and standardization to marker compounds such as glucomoringin or total polyphenols.

Phycocyanin Extract

Phycocyanin-Extrakt

Spirulina platensis pigment

Phycocyanin extract is a water-soluble blue phycobiliprotein derived from Arthrospira (commercially “Spirulina”) that delivers antioxidant, anti-inflammatory and hepatoprotective activity primarily via its tetrapyrrole chromophore, phycocyanobilin. Typical commercial supplements supply **100–1,000 mg/day** of purified phycocyanin (most commonly **200–500 mg/day**). Unlike whole Spirulina, purified phycocyanin is standardized for pigment content (purity often reported as an A620/A280 ratio where >3.5 indicates analytical grade) and used both as a nutraceutical and a natural blue food colorant. Mechanistically, preclinical evidence supports NADPH oxidase (NOX) inhibition, Nrf2/ARE activation (increasing HO-1, NQO1, and glutathione enzymes), and suppression of NF-κB‑driven cytokine production; human clinical data are limited and composed mainly of small biomarker and exercise-recovery trials. Safety concerns focus on product purity (microcystin and heavy metal contamination in poorly controlled Spirulina sources) and potential pharmacodynamic interactions with anticoagulants and antiplatelet drugs.

Slippery Elm Bark Extract

Rotulmen-Rindenextrakt

Ulmus rubra

Slippery elm bark extract (inner bark of Ulmus rubra) is a mucilage‑rich herbal demulcent used traditionally by Native American tribes and modern herbalists for throat and gastrointestinal mucosal soothing. The active fraction is high‑molecular‑weight polysaccharide mucilage (arabinogalactans, rhamnogalacturonans) that forms a viscous, mucoadhesive gel in water and on mucosal surfaces. Typical traditional oral doses range from <strong>2–9 g/day</strong> of powdered bark or <strong>300–500 mg</strong> capsule equivalents; lozenges often contain <strong>200–400 mg</strong> per unit. Systemic absorption of the mucilage is negligible; effects are primarily physical (coating, lubrication), with limited low‑quality clinical evidence supporting symptomatic relief for sore throat and GI irritation. Safety concerns focus on potential reduction of oral drug absorption (separate dosing by <strong>2–4 hours</strong> for narrow‑therapeutic‑index drugs), rare allergic reactions, and quality/sustainability of wild‑harvested bark. This guide synthesizes ethnobotany, pharmacognosy and available clinical/practical data for clinicians and informed consumers in the U.S.

Marshmallow Root Extract

Eibischwurzel-Extrakt

Althaea officinalis

Marshmallow root extract (Althaea officinalis L., radix) is a mucilage-rich botanical used for centuries as a demulcent for irritated mucous membranes and as a topical soothing agent. Modern extracts concentrate high-molecular-weight polysaccharides (arabinogalactans, rhamnogalacturonans) plus flavonoids and phenolic acids that together provide a physical film-forming barrier and supplementary antioxidant/anti-inflammatory activity. Commercial forms include aqueous standardized extracts, glycerites, syrups and lozenges — each optimized for local mucosal contact or topical skin application. Traditional dosing uses 2–5 g dried root as infusion 2–3 times daily; contemporary concentrated extracts commonly range from 300–1,500 mg/day depending on standardization and indication. Marshmallow root is generally well tolerated; main cautions are potential interference with oral drug absorption and sugar content in syrups. High-quality clinical RCTs are limited; regulatory assessments (EMA/ESCOP) recognize traditional use. For precise, up-to-date RCT citations (2020–2026) and PubMed IDs/DOIs, a targeted literature search is recommended and can be performed on request.

Gentian Root Extract

Enzianwurzel-Extrakt

Gentiana lutea

Gentian root extract (Gentiana lutea L., root) is a traditional European bitter botanical standardized most commonly to secoiridoid glycosides such as gentiopicroside and amarogentin. Used for centuries as an aperitif, stomachic and choleretic, modern preparations—tinctures, standardized dry extracts and whole dried root—are marketed in the US as dietary supplements. The extract’s principal mechanism for digestive indications is activation of bitter taste receptors (TAS2Rs) in the oral and gastrointestinal mucosa, producing vagal and enteroendocrine reflexes that increase salivation, gastric acid, pancreatic enzyme and bile secretion. Clinical evidence for single-agent gentian root in randomized controlled trials is limited; most human data derive from traditional monographs, observational use, and combination-product studies with artichoke or other bitter herbs. Typical commercial dosing ranges from 250–1000 mg/day for standardized dry extracts or 2–4 mL of 1:5 tincture taken 15–30 minutes before meals. Safety profile is generally favorable at traditional doses; common adverse events are gastrointestinal (nausea, cramps, diarrhea). Avoid in biliary obstruction, pregnancy, and when alcohol-containing tinctures are contraindicated. For clinical decisions and precise bibliographic citations, a targeted literature search (PMIDs/DOIs) is recommended.

Jatamansi-Extrakt

Nardostachys jatamansi

Jatamansi Extract (Nardostachys jatamansi) is an aromatic Himalayan root/rhizome extract used traditionally in Ayurveda and Tibetan medicine as a nervine, sedative and cognitive tonic. Contemporary phytochemical research identifies oxygenated sesquiterpenes (notably <em>nardosinone</em> and <em>jatamansone</em>), neolignans and phenolics as principal constituents; formulations include dried root powder, hydroalcoholic standardized extracts (titrated to marker sesquiterpenes), steam‑distilled essential oil, and supercritical CO2 concentrates. Preclinical models (rodent behavioral tests and cellular assays) provide evidence for sedative–anxiolytic actions via modulation of GABAergic tone, neurotrophic effects through ERK/CREB/BDNF signaling, antioxidant/Nrf2 activation and anti‑inflammatory (NF‑κB/iNOS/COX‑2) effects. Human randomized controlled trials are sparse to non‑existent in the peer‑reviewed literature as of the primary source provided; therefore clinical dosage guidance is based on traditional practice and commercial formulations (common ranges: <strong>200–600 mg/day</strong> for standardized oral extracts). Use in pregnancy, lactation and pediatrics lacks safety data; caution with CNS depressants, sedative medications, anticonvulsants and anticoagulants is advised.

He Shou Wu Extract

He-Shou-Wu-Extrakt

Polygonum multiflorum

He Shou Wu (Polygonum multiflorum, also marketed as “Fo‑ti”) is a traditional Chinese medicinal root used for centuries as a tonic for hair pigment, vitality, and ‘liver/kidney’ nourishment. Modern phytochemistry identifies two principal marker classes: the hydrophilic stilbene glycoside TSG (2,3,5,4'-tetrahydroxystilbene-2-O-β-D-glucoside) and lipophilic anthraquinones such as emodin. Contemporary preparations vary: aqueous decoctions and processed (zhi) root favor TSG and polysaccharides, while ethanol extracts concentrate anthraquinones and carry higher reported hepatotoxic risk. Typical commercial extract dosing ranges from <strong>200–1,000 mg/day</strong> (common market range), while traditional decoctions commonly use <strong>6–12 g/day</strong> of the raw or processed root. Evidence for benefits is primarily preclinical (antioxidant, neuroprotective, metabolic modulation, hair/follicle support). Importantly, He Shou Wu has been associated with rare but serious herb-induced liver injury (HILI); avoid in active liver disease and monitor LFTs when used long-term. This comprehensive, science‑oriented guide summarizes identification, chemistry, pharmacokinetics, mechanisms, clinical claims, dosing guidance, interactions, safety, quality criteria, and practical advice for US consumers and clinicians.
