Key Phytochemical Constituents

  • Iron oxide nanoparticles (20-100 nm)
  • Silicon dioxide (SiO2) / Silica
  • Aluminum oxide (Al2O3)
  • Magnesium oxide (MgO)
  • Potassium oxide (K2O)
  • Trace organic compounds from herbal processing

How does it work?

  • In vitro studies have reported dose-dependent cytotoxicity, apoptosis induction via mitochondrial pathway, and inhibition of tumor cell proliferation in breast and lung cancer cell lines
  • DNA repair enhancement through stimulation of base excision repair (BER) pathway, protecting against genotoxic damage and chromosomal aberrations
  • Immunomodulatory action through modulation of innate and adaptive immune responses, supporting Rasayana (rejuvenation) properties described in classical texts
  • Hepatoprotective effect at therapeutic doses through antioxidant and cellular membrane stabilization, supporting traditional use in liver disorders

Which traditional uses are supported by research?

These summaries come from the source notes, which do not name the studies behind them.

  • Hepatitis and liver disorders: traditionally used for Yakrit Roga (liver disease). Animal studies have reported hepatoprotective effects.
  • Respiratory diseases (Shwasa, Kasa): traditionally used for Shwasa and Kasa. Preclinical studies on lung cancer cells have reported anti-inflammatory properties.
  • Cancer: traditionally used for Arbuda (tumor) conditions. In vitro studies have reported cytotoxicity against breast and lung cancer cell lines. Clinical translation is pending.
  • Rejuvenation (Rasayana): used in classical practice as a Rasayana (rejuvenation/anti-aging). Studies have reported DNA repair enhancement and immunomodulatory activity.

What do recent studies show?

Only studies that could be traced to a published paper are listed here. An absence here means we could not identify the source, not that no work exists.

Recent safety updates

  • GHS CLASS V (SAFE): LD50 > 2000 mg/kg in acute toxicity per OECD guidelines. Classified as non-toxic at single dose level.
  • DOSE-DEPENDENT HEPATOTOXICITY: Mid and high doses induced REVERSIBLE hepatotoxicity in subacute studies. Low therapeutic doses remain non-toxic.
  • NOT GENOTOXIC: Confirmed non-genotoxic and non-reproductive toxic in mouse models. Actually shows DNA repair enhancement against chemical mutagens.
  • BATCH VARIABILITY CONCERN: Different preparation methods yield physically different end-products. Standardization across manufacturers is a key challenge for consistent safety profiles.
  • FUTURE CLINICAL USE: Would require stringent ethical approval and robust pharmacovigilance systems for clinical application. Post-marketing surveillance essential.

What is it made of?

Mineral/Elemental Profile

  • Iron (Fe): Major component (mica-derived)
  • Silicon (Si): Present (from mica)
  • Aluminum (Al): Present
  • Potassium (K): Present
  • Magnesium (Mg): Trace

Dosage forms and preparation

Dosage Forms: Bhasma (calcined powder)

Standard Dosage: 125–250 mg with honey/ghee

Optimal Timing: With morning/evening meals; with specific anupana

Storage: Airtight glass container; avoid moisture

Marker Compounds: Iron oxide, Silica (mica derivative), Alumina, Trace minerals

Vehicle (Anupana): Honey, ghee, or specific herbal juices depending on target condition

Stability Notes

Properly prepared bhasma is indefinitely stable. Reversion to metallic form indicates improper preparation

Published research

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.
