# Jahar Mohra Pishti

> Jahar Mohra Pishti is a bhasma, a mineral or metal preparation reduced to ash by repeated calcination. An absence here means we could not identify the source, not that no work exists.

## Names and identification

| Language | Name |
|----------|------|
| English | [Jahar Mohra Pishti](/herb/jahar-mohra-pishti/) |

## How does it work?

- Cardiotonic action: [Magnesium](/glossary/compounds-l-o/#magnesium) from the serpentine matrix is essential for cardiac muscle function, rhythm regulation, and blood pressure maintenance; magnesium supplementation is well-established for cardiac health
- Antacid and anti-emetic: Magnesium silicate has documented antacid properties similar to pharmaceutical magnesium-based antacids; acts as a natural buffer against excess gastric acid
- Detoxifying (Vishahara): Traditionally considered an antidote to poisons; the magnesium silicate matrix may adsorb toxins in the GI tract similar to activated charcoal's mechanism

## Which traditional uses are supported by research?

- Cardiac tonic (Hridya): Magnesium's well-established role in cardiac function provides strong mechanistic support for the traditional cardiotonic claim, though specific clinical trials on [Jahar Mohra Pishti](/herb/jahar-mohra-pishti/) are lacking
- Antidote to poisons (Vishanashak) and anti-emetic: The magnesium silicate matrix's adsorptive properties provide a plausible mechanism for the traditional detoxifying/antidote claim

## What do recent clinical trials show?



*2 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

- MODERATE SAFETY: No heavy metals (mercury, arsenic) in properly prepared formulations, but raw serpentine stone may contain chrysotile asbestos fibers in some geological sources - proper Shodhana is essential
- Safety profile not well-established in peer-reviewed literature; clinical experience suggests well-tolerated below 500 mg/day but formal safety studies are lacking
- Contraindicated in patients with individual intolerance, allergic reactions; possible side effects include nausea, abdominal pain, and bowel disorders
- Not recommended during pregnancy and lactation without physician guidance; excessive magnesium intake can cause diarrhea and in extreme cases hypermagnesemia

## What is it made of?
