Key Phytochemical Constituents
- Calcium (22.75% and 41.16% in two bhasma samples by ICP-AES; Singh et al. 2017)
- Calcium oxide (CaO) nanoparticles after calcination
- Copper, zinc, magnesium as trace minerals
- Strontium and phosphorus traces
- Organic matrix proteins from eggshell membrane
How does it work?
- Bioavailable calcium supplementation through CaO nanoparticles providing elemental calcium for bone mineralization, muscle contraction, nerve impulse transmission, and blood clotting
- Antimicrobial action through CaO nanoparticle-mediated disruption of microbial cell membranes; more effective as antifungal agent than antibacterial
- Proposed alkaline buffering through calcium oxide dissolution, which may neutralize excess stomach acid (not clinically established)
- Proposed to support bone mineralization (not clinically established) through release of calcium with trace minerals (Mg, Zn) essential for optimal bone metabolism
Which traditional uses are supported by research?
These summaries come from the source notes, which do not name the studies behind them.
- Calcium deficiency and bone disorders: traditionally used for Asthi Kshaya (bone depletion), rickets, and osteoporosis. Analytical studies have reported a high calcium content with high bioavailability.
- Leukorrhea (Shweta Pradar): traditionally used in gynecological practice for this condition.
- Urinary tract infections: traditionally used for Mutra Krichra (dysuria). Laboratory studies have reported antimicrobial activity of CaO nanoparticles and an alkaline pH.
What do recent studies show?
- Singh TR, Fanasiya KM, Bedarkar P and others 2017. Analytical profile of Kukkutanda Tvak Bhasma (incinerated hen egg shells) prepared by two different methods. Ayu. PMID 30254398 · doi:10.4103/ayu.AYU_209_17
Comparative analytical study established quality parameters for two preparation methods. Confirmed calcium oxide as primary constituent with consistent physicochemical profiles.
Only studies that could be traced to a published paper are listed here. An absence here means we could not identify the source, not that no work exists.
Recent safety updates
- LIKELY SAFE: Classified as LIKELY SAFE AND WELL TOLERABLE in most people. No significant side effects reported with regular use for 3-6 months.
- EGG ALLERGY CAUTION: Patients with egg allergies should use with caution, though eggshell protein content is minimal after calcination
What is it made of?
Mineral/Elemental Profile

- Magnesium (Mg): Trace
- Phosphorus (P): Trace
- Strontium (Sr): Trace

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.

Reviewed by Dr. Awadesh Pratap Singh, BAMS, on 11 October 2026. What that review covered.
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.
