# Vanga Bhasma

> Vanga Bhasma is a bhasma, a mineral or metal preparation reduced to ash by repeated calcination. [TOXICITY STUDIES ON VANGA BHASMA (Part I - with special reference to G. Liver and Pancreas)](https://pubmed.ncbi.nlm.nih.gov/22557446/).

## Names and identification

| Language | Name |
|----------|------|
| English | [Vanga Bhasma](/herb/vanga-bhasma/) |

## Key Phytochemical Constituents

- Tin oxide (SnO2) as primary constituent
- Tin sulfide from [Gandhaka](/glossary/concepts-a-m/#gandhaka) processing
- Trace metals from processing equipment
- Organic compounds from herbal media
- [Silicon](/glossary/compounds-q-t/#silicon) and aluminum as trace impurities

## How does it work?

- [Vajikarana](/glossary/pharmacology/#vajikarana) ([aphrodisiac](/glossary/pharmacology/#aphrodisiac)) action through testicular regenerative potential, enhancing spermatogenesis and male reproductive function as demonstrated in animal studies
- Pramehaghna (anti-diabetic) activity through pancreatic beta-cell support and improvement of insulin sensitivity, part of [Trivanga Bhasma](/herb/trivanga-bhasma/)'s documented anti-diabetic mechanism
- Medohara (anti-obesity) action through modulation of lipid metabolism pathways, reducing excessive adipose tissue accumulation
- Mutravaha Srotas (urinary system) support through [diuretic](/reference/diuretic/) and anti-lithiatic effects, helping manage urinary tract disorders

## Which traditional uses are supported by research?

- Male reproductive disorders (Vajikarana): Testicular regenerative potential demonstrated in animal studies, supporting aphrodisiac claims
- Urinary disorders (Prameha/Mutra Roga): Traditional use partially validated through inclusion in [Trivanga Bhasma](/herb/trivanga-bhasma/) studies showing urinary system benefits
- Diabetes (Madhumeha): Anti-diabetic activity validated as component of [Trivanga Bhasma](/herb/trivanga-bhasma/) in multiple animal studies

## What do recent clinical trials show?

- Nagaraju V, Joshi D, Aryya NC 1984. [TOXICITY STUDIES ON VANGA BHASMA (Part I - with special reference to G. I. T. Liver and Pancreas)](https://pubmed.ncbi.nlm.nih.gov/22557446/). *Ancient science of life*. PMID [22557446](https://pubmed.ncbi.nlm.nih.gov/22557446/)  
  No significant toxicity attributable to [Vanga Bhasma](/herb/vanga-bhasma/) observed even at 8 times higher dose than therapeutic dose on 10-day exposure. GIT, liver, and pancreas showed no pathological changes.
- Nagaraju V, Joshi D, Aryya NC 1985. [Study on the vrsya property (testicular regenerative potential) of vanga bhasma](https://pubmed.ncbi.nlm.nih.gov/22557499/). *Ancient science of life*. PMID [22557499](https://pubmed.ncbi.nlm.nih.gov/22557499/)  
  [Vanga Bhasma](/herb/vanga-bhasma/) demonstrated testicular regenerative potential in animal models, supporting traditional Ayurvedic use as Vajikarana (aphrodisiac) preparation.
- Liu J, Zhang F, Ravikanth V and others 2019. [Chemical Compositions of Metals in Bhasmas and Tibetan Zuotai Are a Major Determinant of Their Therapeutic Effects and Toxicity](https://pubmed.ncbi.nlm.nih.gov/30941186/). *Evidence-based complementary and alternative medicine : eCAM*. PMID [30941186](https://pubmed.ncbi.nlm.nih.gov/30941186/) · [doi:10.1155/2019/1697804](https://doi.org/10.1155/2019/1697804)  
  Chemical form of metals (oxide vs sulfide vs metallic) in Bhasmas is the major determinant of therapeutic effect vs toxicity. Properly prepared [Vanga Bhasma](/herb/vanga-bhasma/) with tin in oxide form shows lower toxicity than metallic tin.

## Recent safety updates

- RELATIVELY SAFE PROFILE: No toxicity at 8x therapeutic dose for 10 days; GIT, liver, and pancreas remained normal in histopathological examination
- HEAVY METAL INDUSTRY CONCERN: Over 20% of Ayurvedic medications may contain toxic metals; tin-based preparations must be properly purified to ensure conversion to non-toxic oxide form
- LIMITED LONG-TERM DATA: Most safety studies are short-duration (10-90 days). Long-term chronic exposure data for tin Bhasma specifically is limited.
- REPRODUCTIVE USE CAUTION: While traditionally used as Vajikarana, proper dose calibration is essential as excessive tin exposure can have adverse reproductive effects

## What is it made of?

### Mineral/Elemental Profile

- **Tin oxide (SnO2):** Major component
