Ayurveda Sara Sangraha (Ayurved Saar Sangrah); also referenced in classical Rasashastra texts
How does it work?
- Triple iron source (Loha Bhasma + Mandura Bhasma + Swarnamakshik Bhasma) provides multi-form bioavailable iron for robust hemoglobin synthesis
- Raupya Bhasma (silver calx) has antimicrobial and Pitta-pacifying properties, supporting liver detoxification pathways
- Shilajit acts as a potent bioenhancer containing fulvic acid that markedly improves mineral absorption and cellular iron uptake
- Daruharidra (Berberis aristata) contains berberine, providing hepatoprotective and cholagogue effects supporting liver and biliary function
- Trikatu enhances bioavailability and digestive fire (Agni deepana) for optimal nutrient assimilation
- Triphala provides antioxidant protection, gentle bowel regulation (preventing iron-induced constipation), and vitamin C for iron absorption
Which traditional uses are supported by research?
- Pandu (anemia) and Kamla (jaundice-like conditions) - validated through traditional clinical use and supported by the known hematinic and hepatoprotective actions of constituent ingredients
- Liver and spleen disorders (Yakrit-Pliha Roga) - traditional use supported by hepatoprotective properties of Daruharidra (berberine), Shilajit, and Triphala; 2024 toxicity study showed no hepatotoxicity

Tapyadi Loha showed no mortality or signs of toxicity at single oral dose of 2000 mg/kg; 28-day repeated dose at 1000 mg/kg showed no behavioral, hematological, biochemical, or histopathological abnormalities - confirmed safe at tested doses

Recent safety updates
- 2024 toxicity study confirmed safety at single dose of 2000 mg/kg and 28-day repeated dose of 1000 mg/kg in rat models with no adverse effects
- Contains multiple iron sources (Loha + Mandura + Swarnamakshik) - higher cumulative iron intake requires careful monitoring of serum ferritin and iron studies
- Raupya Bhasma (silver) content requires verification of proper preparation (Shodhana) and heavy metal testing per API standards
- Contraindicated in hemochromatosis, iron overload conditions, active liver disease (despite hepatoprotective herbs), and during pregnancy without supervision
- Should be used under strict medical supervision with regular LFT and KFT monitoring; recommended treatment duration should not be exceeded

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.

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.
