# Hajrul Yahood Bhasma

> Hajrul Yahood Bhasma is a bhasma, a mineral or metal preparation reduced to ash by repeated calcination. Kidney stones (Ashmari): Lithontriptic and diuretic activity confirmed in research.

## Names and identification

| Language | Name |
|----------|------|
| English | [Hajrul Yahood Bhasma](/herb/hajrul-yahood-bhasma/) |

## Key Phytochemical Constituents

- Calcium silicate (CaSiO3) as primary constituent
- Calcium oxide (CaO) from thermal decomposition
- [Silicon](/glossary/compounds-q-t/#silicon) dioxide (SiO2)
- Trace [magnesium](/glossary/compounds-l-o/#magnesium), iron, aluminum
- Organic compounds from radish/herbal trituration media

## How does it work?

- Lithontriptic (stone-dissolving) action through calcium silicate-mediated chemical dissolution of calcium oxalate and calcium phosphate kidney stones
- [Diuretic](/reference/diuretic/) action through osmotic and ionic mechanisms, increasing urinary volume and flow to facilitate stone passage from kidneys through ureters
- Anodyne (pain-relieving) action reducing renal colic, observed clinically within 2-3 doses, likely through smooth muscle relaxation in urinary tract
- Gastroprotective effect through acid neutralization and mucosal protection, demonstrated in clinical trial showing 72% ulcer healing rate

## Which traditional uses are supported by research?

- Kidney stones (Ashmari): Lithontriptic and diuretic activity confirmed in research. Anodyne action reducing renal colic within 2-3 doses validated clinically.
- Gastric ulcers: Clinical trial showed 72% ulcer-healing rate with Hajrul Yahood + licorice vs 45% with ranitidine, validating gastroprotective use
- Dysuria and urinary disorders: Diuretic and smooth muscle relaxant properties support traditional use for painful urination (Mutrakrichra)

## What do recent clinical trials show?



*3 further claims previously listed here could not be traced to a published paper and have been removed. An absence here means we could not identify the source, not that no work exists.*

## Recent safety updates

- RELATIVELY SAFE: Calcium silicate-based preparation without toxic heavy metals. Lower risk profile compared to metallic Bhasmas.
- CLINICAL EVIDENCE: Clinical trial data available showing therapeutic efficacy, a rarity among Bhasma preparations
- KIDNEY FUNCTION MONITORING: Long-term use should include periodic kidney function assessment, especially in patients with pre-existing renal conditions
- DRUG INTERACTIONS: May interact with antibiotics (tetracyclines, fluoroquinolones) and other calcium-binding drugs. Spacing of administration recommended.

## What is it made of?

### Mineral/Elemental Profile
