# Gomeda Bhasma

> Gomeda Bhasma is a bhasma, a mineral or metal preparation reduced to ash by repeated calcination. [Bhasma : The ancient Indian nanomedicine](https://pubmed.ncbi.nlm.nih.gov/24696811/). Journal of advanced pharmaceutical technology & research. PMID [24696811](https://pubmed.ncbi.nlm.nih.gov/24696811/) · [doi:10.4103/2231-4040.126980](https://doi.org/10.4103/2231-4040.126980) Gemstone Bhasmas including Gomeda described as non-toxic nanomedicines when prepared following classical Ayurvedic processes.

## Names and identification

| Language | Name |

| English | [Gomeda Bhasma](/herb/gomeda-bhasma/) |

## Key Phytochemical Constituents

- Calcium aluminium silicate as primary mineral matrix
- Calcium oxide from thermal decomposition
- Aluminium oxide (Al2O3)
- [Silicon](/glossary/compounds-q-t/#silicon) dioxide (SiO2)
- Iron and [manganese](/glossary/compounds-l-o/#manganese) traces (responsible for garnet color)

## How does it work?

- [Neuroprotective](/reference/neuroprotective/) action through mineral-mediated modulation of neuronal excitability and neurotransmitter balance, supporting management of epilepsy and insomnia
- [Cardioprotective](/reference/cardioprotective/) effect through regulation of cardiac conduction pathways and anti-arrhythmic properties, particularly useful for tachycardia and palpitation
- [Anxiolytic](/reference/anxiolytic/) and sedative action through CNS-modulating mineral constituents, promoting mental calm and stress reduction
- Tridosha balancing through multi-mineral silicate composition providing trace elements needed for systemic homeostasis

## Which traditional uses are supported by research?

- Neurological disorders (epilepsy, insomnia, paralysis): Traditional indications documented through extensive clinical practice; mineral composition provides mechanistic plausibility for neuromodulation
- Cardiac arrhythmias and palpitation: Traditional use for heart rhythm disorders supported by mineral electrolyte effects on cardiac conduction
- Stress and mental clarity: Anxiolytic properties supported by traditional clinical observations, though formal clinical trials lacking

## What do recent clinical trials show?

- Pal D, Sahu CK, Haldar A 2014. [Bhasma : The ancient Indian nanomedicine](https://pubmed.ncbi.nlm.nih.gov/24696811/). *Journal of advanced pharmaceutical technology & research*.

  Gemstone Bhasmas including Gomeda described as non-toxic nanomedicines when prepared following classical Ayurvedic processes. The incineration process is key to converting toxic starting materials to safe therapeutic forms.

## Recent safety updates

- NO ABSOLUTE CONTRAINDICATIONS: Gomed Stone Bhasma has no reported absolute contraindications per Ayurvedic literature
- LIMITED MODERN SAFETY DATA: Rigorous toxicological studies specifically on [Gomeda Bhasma](/herb/gomeda-bhasma/) are scarce. Most safety evidence is traditional/empirical.
- ALUMINIUM CONTENT: Contains aluminium oxide; chronic aluminium exposure concerns apply, particularly for renal-compromised patients
- PRACTITIONER SUPERVISION: Must be used only under guidance of qualified Ayurvedic practitioner due to limited standardization data
