Bhringraj (Eclipta prostrata) is an Ayurvedic herb containing bioactive compounds wedelolactone and ecliptin that promote hair growth through follicle stimulation. The herb demonstrates hepatoprotective effects by suppressing NF-κB inflammatory pathways in preclinical studies.
Bhringraj (Eclipta prostrata) is a creeping annual herb from the Asteraceae family native to tropical and subtropical regions worldwide, particularly India. The plant grows in moist areas, with medicinal preparations made from whole plant, aerial parts, leaves, or roots using extraction methods including n-hexane, ethanol, ethyl acetate, or water to isolate bioactive compounds.
The research dossier reveals a notable absence of human clinical trials, RCTs, or meta-analyses with PubMed PMIDs for Eclipta prostrata. Current evidence is limited to preclinical, ethnopharmacological, animal, and in vitro studies, with no rigorous clinical data available for outcomes like hair growth, liver protection, or anticancer effects.
No clinically studied dosage ranges have been established for Eclipta prostrata extracts, powders, or standardized forms as human trials are not reported. Traditional Ayurvedic use involves oral or topical application of powders or oils, but without standardization details or quantified doses from studies. Consult a healthcare provider before starting any new supplement.
Bhringraj (Eclipta prostrata) is a medicinal herb rather than a dietary staple, so macronutrient content is not nutritionally significant in typical therapeutic doses. However, phytochemical and proximate analyses reveal the following: Crude protein approximately 18–22% of dry weight in leaf material; crude fiber approximately 15–20% dry weight; crude fat approximately 2–4% dry weight; ash content approximately 8–12% dry weight indicating moderate mineral density. Key bioactive compounds include: Wedelolactone (coumestan) at approximately 0.1–0.5% w/w in dried aerial parts — the primary hepatoprotective and anti-inflammatory constituent with documented NF-κB inhibitory activity; Demethylwedelolactone present alongside wedelolactone at lower concentrations (~0.05–0.2% w/w); Ecliptine and other alkaloids at trace levels (<0.1%); Eclalbatin and oleanolic acid (triterpenoid saponins) contributing to membrane-stabilizing effects; Luteolin and apigenin (flavonoids) at approximately 0.2–0.8% dry weight with antioxidant properties; β-Sitosterol and stigmasterol (phytosterols) present in lipid fraction; Polyacetylenes including thiophene derivatives identified in root extracts. Mineral content in dried leaf: Iron approximately 150–300 mg/kg dry weight (notably high, supporting traditional use for hair and blood); Calcium approximately 1,200–2,000 mg/kg; Magnesium approximately 300–500 mg/kg; Zinc approximately 20–40 mg/kg. Vitamins: Vitamin C (ascorbic acid) approximately 40–90 mg/100g fresh weight; Vitamin E (tocopherols) present in small quantities (~5–15 mg/100g dry weight). Bioavailability notes: Wedelolactone demonstrates moderate oral bioavailability in rodent models with significant first-pass hepatic metabolism; lipid-based formulations or oil infusions (traditional tailam preparations) may enhance absorption of fat-soluble constituents including phytosterols and certain flavonoids; iron bioavailability is likely moderate-to-low due to concurrent presence of tannins and fiber that can chelate non-heme iron; aqueous extracts preferentially extract wedelolactone and flavonoids, while oil-based preparations extract phytosterols and fat-soluble pigments including chlorophyll derivatives responsible for the plant's characteristic dark green color.
Wedelolactone, the primary bioactive compound, represses nuclear factor-κB (NF-κB) signaling to reduce inflammatory cytokine production and liver fibrosis. Ecliptin and coumestan derivatives stimulate hair follicle cells and melanocyte activity to promote hair growth and pigmentation. The herb's triterpenes modulate antioxidant enzyme systems including superoxide dismutase and catalase.
Human clinical trials for bhringraj are currently lacking, with evidence primarily based on traditional use spanning over 2,000 years in Ayurveda. Animal studies demonstrate significant hepatoprotective effects, with wedelolactone reducing liver enzyme markers by 40-60% in toxin-induced liver damage models. In vitro studies show hair follicle stimulation and melanogenesis promotion, but controlled human trials are needed to establish clinical efficacy. Most available evidence comes from preclinical research and traditional medicine documentation.
Bhringraj is generally well-tolerated with mild gastrointestinal upset reported in some users at higher doses. The herb may interact with anticoagulant medications due to coumarin content, requiring monitoring in patients on warfarin. Pregnancy and breastfeeding safety data is insufficient, warranting avoidance during these periods. Allergic reactions are rare but possible, particularly in individuals sensitive to plants in the Asteraceae family.
