How does it work?
- Loha Bhasma provides bioavailable iron to correct anemia secondary to excessive menstrual blood loss
- Tamra Bhasma (copper calx) supports copper-dependent enzymes essential for iron metabolism and ceruloplasmin synthesis
- Abhraka Bhasma (mica calx) provides trace minerals and acts as a Rasayana (rejuvenative), strengthening uterine tissue
- Trikatu (Shunthi + Maricha + Pippali) enhances absorption of mineral Bhasmas and stimulates Agni (digestive fire)
- Triphala components provide hemostatic, anti-inflammatory, and antioxidant effects supporting uterine health
- Varatika Bhasma (cowrie shell calx) provides calcium and acts as a uterine tonic reducing excessive bleeding
Which traditional uses are supported by research?
- Menorrhagia and metrorrhagia (Pradara/excessive menstrual bleeding) - traditional use supported by clinical observations showing reduced menstrual blood loss and improved hemoglobin
- Leucorrhea (Shweta Pradara) - traditional gynecological application validated through clinical practice with reported improvement in vaginal discharge and associated symptoms

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.
