Where is it described in the classical texts?
Bhaishajya Ratnavali, Pandu Roga Chikitsa (Anemia Treatment Chapter)
How does it work?
- Loha Bhasma (9 parts, 30 calcinations) provides nano-particulate bioavailable iron for hemoglobin synthesis and RBC production
- Trikatu (Shunthi + Maricha + Pippali) enhances bioavailability of iron through improved GI absorption and stimulation of digestive enzymes (Agni deepana)
- Triphala (Haritaki + Bibhitaka + Amalaki) provides vitamin C for iron absorption enhancement, gentle laxative action to prevent iron-induced constipation, and antioxidant protection
- Chitraka (Plumbago zeylanica) acts as a potent digestive stimulant (Agni deepana), improving nutrient assimilation and iron uptake
- Vidanga (Embelia ribes) provides anthelmintic action removing intestinal parasites that may cause or worsen anemia, plus its own hematinic properties
- Musta (Cyperus rotundus) aids digestion and has anti-inflammatory properties, reducing intestinal inflammation that impairs iron absorption
Which traditional uses are supported by research?
- Iron deficiency anemia (Pandu Roga) - validated in multiple clinical and observational studies showing statistically significant increases in hemoglobin, PCV, and RBC count
- General debility and weakness associated with anemia - clinical studies confirm improvement in energy levels, appetite, and overall vitality metrics
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
- Clinical trials showed no side effects on liver or kidney function tests during treatment period
- Prolonged use beyond prescribed duration may risk iron overload; periodic monitoring of serum ferritin and transferrin saturation recommended
- Contraindicated in hemochromatosis and iron storage disorders; pre-treatment iron studies advised
- Contains no mercury or other toxic heavy metals - purely herbo-iron formulation with better safety profile than mercury-containing Rasa preparations
- Chitraka (Plumbago zeylanica) at high doses can be irritant; formulation ratio ensures safe levels but gastric sensitivity should be monitored

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.
