Mandura Bhasma: What It Is, Evidence & Heavy-Metal Safety
TL;DR
Mandura Bhasma is not a herb but a classical Ayurvedic herbo-metallic iron preparation: Mandura (iron rust) purified and incinerated with herbal juices, traditionally used for Pandu (anemia). Rat studies report blood-building (haematinic) effects; human evidence is limited to case reports. Because bhasmas carry documented heavy-metal poisoning risks when poorly made, we publish no dosage.

What it is
Mandura Bhasma is a Rasa Shastra (Ayurvedic alchemy/pharmaceutics) preparation: a bhasma, meaning a metal or mineral reduced by repeated purification (shodhana) and incineration (marana) with herbal juices into a fine ash-like powder. Its starting material is Mandura, known as Lauha Kitta, iron rust/iron oxide, and classical compound formulations containing it include Punarnava Mandura (clinical study of Punarnava Mandura in iron-deficiency anemia). It is not a single herb, and it is not the same thing as an iron supplement tablet.
Traditional use
In classical Ayurveda, Mandura Bhasma and its compound formulations are indicated for Pandu roga: the classical correlate of anemia. The Bhaishajya Ratnavali states that if lauha (iron) is unavailable, Mandura may be taken as an alternative (same clinical study). Classical texts treat bhasmas as potent, low-dose medicines prepared under strict protocols: a traditional claim about their preparation, not clinical proof of effect.
What modern research says
Blood-building effects (animal study)
Sarkar and colleagues evaluated two Ayurvedic iron preparations, Lauha bhasma and Mandura bhasma, each at 11 mg/kg, in rats with mercuric-chloride-induced anemia, and reported significant haematinic and cytoprotective activity (Sarkar et al., Indian Journal of Pharmaceutical Sciences). This is an animal study; it does not prove Mandura Bhasma raises hemoglobin in humans.
Human evidence: a single case report
A 2025 case report described a 10-year-old child with severe anemia treated with Mandura Bhasma plus Rohitakarishta and iron-rich dietary advice. Hemoglobin rose significantly and no adverse effects were reported (Sarkar et al., J Ayurveda Integr Med Sci 2025). A single case, treated with a combination: this cannot isolate Mandura Bhasma's effect and is not clinical proof.
What properly made bhasmas look like under the microscope
A 2025 review of bhasma pharmacology notes that classical texts emphasize shodhana and marana to detoxify metals and convert them into therapeutic particles, and that modern analytical studies confirm properly prepared bhasmas exist as nano-to-microparticles with organometallic complexes: chemically distinct from raw toxic metals (Asian J Dravyaguna & Pharmacology 2025). This supports the idea that a bhasma is a processed material, not raw metal: but it is not a safety guarantee for any given product.
What the evidence does not support (yet)
No randomized human trials of Mandura Bhasma were found. Claims that it treats anemia in humans rest on classical authority, one animal study, and case reports: not on controlled clinical evidence.
Safety & contraindications: the heavy-metal question, honestly
This is the section that matters most, because herbo-metallic medicines carry a documented safety problem:
- Documented poisonings exist. A public-health investigation of Ayurvedic products linked to lead poisoning found that roughly 50% of tested samples exceeded recommended daily oral exposure values for lead, mercury, arsenic, or cadmium, some by a factor of several thousand, and noted that numerous case reports from several countries have shown the traditional "detoxification" claim to be ineffective in practice (PMC6060866).
- The pattern is manufacturing quality. A 2021 systematic scoping review of 220 cases of heavy-metal toxicity from traditional Indian medicines concluded the metals are often the result of adulteration or improper manufacturing and prescribing practices, despite national and international quality guidelines (Mukhopadhyay et al., J Altern Complement Med 2021, via PubMed).
- The counterpoint. The 2025 bhasma review argues that preclinical studies show standardized bhasmas are safe within therapeutic ranges, and that the risks concentrate in nonstandard preparations and contamination: making stringent quality control and analytical validation essential (AJDP 2025).
Bottom line: Mandura Bhasma should only ever be considered as a product of a licensed manufacturer, under the supervision of a qualified practitioner: never from an unknown or unregulated source, and never self-prescribed. Tell your doctor you are taking it, so blood counts and iron studies can be monitored. We publish no dosage for Mandura Bhasma: with no pharmacopoeial citation verified for this page and a documented quality-safety problem in the product category, giving an amount would be irresponsible.
FAQs
What is mandura bhasma made from?
Its starting material is Mandura (Lauha Kitta: iron rust/iron oxide), which is purified and repeatedly incinerated with herbal juices into a fine bhasma powder. It appears in classical formulations such as Punarnava Mandura (Punarnava Mandura clinical study).
Is mandura bhasma just iron?
No. It is a processed herbo-metallic preparation, not elemental iron and not equivalent to an iron supplement tablet. Modern analytical work describes properly prepared bhasmas as nano-to-microparticles chemically distinct from raw metals: but that describes the process, not a guarantee about any product on a shelf (AJDP 2025).
Does mandura bhasma work for anemia?
Unproven in humans. A rat study reported blood-building effects at 11 mg/kg (Indian J Pharm Sci), and a single pediatric case report described hemoglobin improvement with a Mandura Bhasma-containing regimen (J Ayu Int Med Sci 2025). There are no randomized human trials.
Are bhasmas safe from heavy-metal contamination?
Not automatically. Investigations have found Ayurvedic products with lead, mercury, arsenic, and cadmium far above safe exposure values, and a scoping review of 220 toxicity cases blames adulteration and improper manufacturing (PMC6060866; PubMed 34142855). Only products from licensed manufacturers, taken under qualified supervision, should ever be considered.
Why does this page give no dosage?
Dosage appears on Swastik pages only with a pharmacopoeial or clinical-trial citation: and for a herbo-metallic preparation in a product category with documented heavy-metal poisoning cases, publishing an amount without that backing would be irresponsible.
