Mandura Bhasma

Mandura Bhasma is a bhasma, a mineral or metal preparation reduced to ash by repeated calcination. [Physicochemical characterization of an Iron based Indian traditional medicine: Mandura Bhasma](https://pubmed.ncbi.nlm.nih.gov/23284206/). PMID [23284206](https://pubmed.ncbi.nlm.nih.gov/23284206/) Iron oxide nanoparticles confirmed by XRD and SEM analysis.

Key Phytochemical Constituents

  • Ferric oxide (Fe2O3) as primary constituent (~40-45% elemental iron)
  • Magnetite (Fe3O4) phase
  • Calcium, magnesium from processing media
  • Silica and alumina traces
  • Vitamin C and tannins from Amalaki (gooseberry) processing

How does it work?

  • Hematopoietic iron supplementation through bioavailable iron oxide particles that support hemoglobin synthesis without the typical GI side effects of conventional iron salts
  • Hepatoprotective and spleen-supportive action through iron-mediated improvement of reticuloendothelial system function and blood filtration
  • Deepana-Pachana (digestive enhancement) through iron-catalyzed metabolic enzyme activation and improvement of nutrient absorption
  • Raktavardhaka (blood-building) action through combined iron supplementation and vitamin C (from Amalaki processing) synergy enhancing iron absorption

Which traditional uses are supported by research?

  • Iron-deficiency anemia (Pandu Roga): Clinical trials confirmed significant hemoglobin improvement (1.2 g/dL over 8 weeks) with no adverse effects
  • Menstrual disorders (Raktapradar): Over 40% reduction in menstrual blood loss in 65 women within two treatment cycles
  • Liver and spleen enlargement (Yakrit-Pleeha Vikara): Hepatoprotective activity and reticuloendothelial support partially validated through preclinical studies

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

  • SAFE AT 5X DOSE: No serious toxic effects at 55 mg/kg (5x therapeutic dose) for 60 days in rat studies
  • CLINICAL SAFETY CONFIRMED: No adverse drug reactions or events in clinical trials with Punarnavadi Mandura formulation
  • IRON OVERLOAD MONITORING: Excessive or long-term use without monitoring may lead to elevated serum ferritin and oxidative stress. Periodic hemoglobin and ferritin checks advised.
  • BETTER TOLERATED: Like Loha Bhasma, Mandura Bhasma causes fewer GI side effects than conventional iron supplements due to oxide nanoparticle form

What is it made of?

Mineral/Elemental Profile

  • Iron oxide (Fe2O3): Major component (iron slag)
  • Silicon (Si): Trace
  • Manganese (Mn): Trace
  • Calcium (Ca): Trace

Analytical Methods: XRD, ICP-OES, SEM-EDS

Dosage forms and preparation

Dosage Forms: Bhasma

Standard Dosage: 250–500 mg twice daily

Bioavailability: Good; iron oxide from natural rust/slag; gentler than Loha Bhasma

Optimal Timing: After meals with Triphala Kwatha or honey

Standardized Extract: Calcined iron rust/slag bhasma

Shelf Life: Indefinite

Storage: Airtight container

Marker Compounds: Iron oxide (Fe2O3), Silica, Trace manganese and magnesium

Quality Parameters: Iron >40%, standard bhasma tests, no free metallic iron

Vehicle (Anupana): Triphala Kwatha, honey, or as Mandura Vataka formulation

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.
