Kanmad Bhasma
Kanmad Bhasma is a bhasma, a mineral or metal preparation reduced to ash by repeated calcination. [Structural investigation of Ayurveda Lauha (Iron) Bhasma](https://pubmed.ncbi.nlm.nih.gov/36822148/). Journal of Ayurveda and integrative medicine. 2 further claims previously listed here could not be traced to a published paper and have been removed.

Key Phytochemical Constituents
- Magnetite (Fe3O4) - primary phase
- Hematite (Fe2O3) from oxidation during processing
- Fe2+/Fe3+ ratio optimized through calcination
- Trace carbon, sodium, zinc as minor elements
- Nanocrystalline iron oxide particles with magnetic properties
How does it work?
- Superior iron bioavailability through magnetite nanoparticle form providing both Fe2+ and Fe3+ ions in optimal ratio for intestinal absorption and hemoglobin synthesis
- Potential magnetic hyperthermia therapy through nanocrystalline magnetite generating localized heat under alternating magnetic field for cancer cell killing
- Hematopoietic support through efficient iron delivery to bone marrow for red blood cell production, superior to ordinary iron preparations
- Metabolic enhancement through iron-dependent enzyme cofactor provision supporting cellular respiration, DNA synthesis, and energy metabolism
Which traditional uses are supported by research?
- Iron-deficiency anemia (Pandu Roga): Iron supplementation efficacy well-established; magnetite form provides superior bioavailability per Ayurvedic and modern analysis
- Diabetes (Madhumeha): Traditional use supported by iron’s role in glucose metabolism regulation and insulin sensitivity enhancement
- Chronic fevers (Jeerna Jwara): Anti-microbial and immune-supporting properties of iron compounds provide partial mechanistic validation

Lauha Bhasma from magnetite has great potential for noninvasive localized target killing of cancer cells via necrosis by application of alternating external magnetic field or photoelectron generation through X-rays.

Recent safety updates
- SUPERIOR TO ORDINARY IRON: Kanta Loha Bhasma considered safest and most potent iron preparation in Ayurveda due to natural magnetite source
- DOSE LIMIT: Should not exceed 500 mg/day. Overuse can cause constipation, stomach upset, or iron toxicity.
- PROPER PREPARATION ESSENTIAL: Must undergo complete Shodhana, Marana, and Amruteekarana processes. Improperly prepared magnetite may contain heavy metal contaminants.
- IRON OVERLOAD MONITORING: Like all iron preparations, periodic hemoglobin, serum ferritin, and liver function monitoring recommended during prolonged use
What is it made of?
Mineral/Elemental Profile
- Iron oxide (Fe2O3): Major component (iron ore)
- Iron (Fe): >60%
- Silicon (Si): Trace
- Aluminum (Al): Trace

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.
