Trivanga Bhasma
Trivanga Bhasma is a bhasma, a mineral or metal preparation reduced to ash by repeated calcination. However, lead toxicity risk undermines clinical applicability.

Key Phytochemical Constituents
- Lead oxide/sulfide (~31.67% lead content)
- Tin oxide (~38.36% tin content)
- Zinc oxide (~17.1% zinc content)
- Sulfur compounds from Gandhaka processing
- Herbal organic residues from trituration media
How does it work?
- Anti-diabetic action through combined zinc-mediated insulin sensitivity enhancement and pancreatic beta-cell support, with synergistic effects from trimetallic composition
- Urinary system regulation through diuretic and anti-lithiatic effects of combined metals, supporting management of Prameha (urinary disorders)
- Reproductive system support through tin (Vanga) mediated spermatogenesis enhancement and zinc-dependent reproductive hormone regulation
- Metabolic regulation through multi-metal enzyme cofactor provision affecting carbohydrate, lipid, and protein metabolism pathways
Which traditional uses are supported by research?
- Diabetes (Madhumeha): Anti-diabetic activity demonstrated in STZ-induced diabetic rat models with significant blood sugar reduction. However, lead toxicity risk undermines clinical applicability.
- Urinary disorders (Mutra Roga): Traditional indication partially supported by component metal properties, but no specific clinical validation separating efficacy from toxicity
- Infertility (Vandhyatva): Reproductive support claimed from Vanga component, but lead content makes this use particularly dangerous for reproductive health

No treatment-related effects up to 10x therapeutic dose (78 mg/kg body weight = NOEL). Normal cyto-architecture at therapeutic doses. Toxicity in liver and kidney observed only at very high dose (10x TED). - Rasheed A, Naik M, Mohammed-Haneefa KP and others 2014.

Physicochemical characterization confirmed trimetallic composition. Comparative evaluation of preparations from different sources showed variations in metal content ratios.

Recent safety updates
- CONTAINS LEAD (31.67%): Despite Ayurvedic purification, lead content remains a serious safety concern. Lead has NO safe exposure level per modern toxicology.
- SAFE AT THERAPEUTIC DOSE IN ANIMALS: NOEL of 78 mg/kg in mice. No treatment effects up to 10x therapeutic dose except at highest level (liver/kidney toxicity).
- LEAD ACCUMULATION RISK: Chronic use may lead to cumulative lead exposure. Blood lead level monitoring essential for any patient taking this preparation.
- REGULATORY CONFLICT: While AYUSH permits its manufacture, FDA and WHO guidelines effectively prohibit lead-containing medicines. This creates a regulatory paradox.
- SAFER ALTERNATIVES AVAILABLE: Zinc-only (Yashada Bhasma) preparations provide similar anti-diabetic benefits without lead toxicity risk.

Literature indexed in PubMed that concerns this subject, grouped by study type. A paper appearing here is a record of what has been published, not evidence that the subject works, and laboratory or animal results do not transfer to people. Study titles link to PubMed so you can read the source rather than take our word.

Consult a qualified vaidya before acting on anything here. Ayurvedic practice is prescribed to a person, not to a condition: the same dravya is given, withheld or substituted depending on your constitution, your agni, the season and what else you are already taking. A page cannot know any of that. Self-prescribing from a reference is how the wrong preparation, the wrong dose or the wrong anupana gets used.
Educational reference only. Nothing on this page is medical advice, a diagnosis, or a recommendation to take anything. Traditional uses and research findings are reported as published, not as claims about what any product does. If you take prescribed medication, raise any interaction with the prescriber rather than acting on a page. See our editorial standards.
