Kukkutanda Twak Bhasma
Kukkutanda Twak Bhasma is a bhasma, a mineral or metal preparation reduced to ash by repeated calcination. [Analytical profile of Kukkutanda Tvak Bhasma (incinerated hen egg shells) prepared by two different methods](https://pubmed.ncbi.nlm.nih.gov/30254398/).

Key Phytochemical Constituents
- Calcium (60.83%) - highest among similar preparations
- 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
- Alkaline buffering through calcium oxide dissolution creating alkaline pH in stomach, neutralizing excess acid and providing gastroprotective effect
- Bone density improvement through sustained release of bioavailable calcium with trace minerals (Mg, Zn) essential for optimal bone metabolism
Which traditional uses are supported by research?
- Calcium deficiency and bone disorders: 60.83% calcium content with high bioavailability confirmed analytically, validating use for Asthi Kshaya (bone depletion), rickets, and osteoporosis
- Leukorrhea (Shweta Pradar): Traditional gynecological use supported by calcium’s role in reproductive health and mucosal integrity
- Urinary tract infections: Antimicrobial CaO nanoparticle activity and alkaline pH effects support traditional use for Mutra Krichra (dysuria)

Comparative analytical study established quality parameters for two preparation methods. Confirmed calcium oxide as primary constituent with consistent physicochemical profiles.
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
- LIKELY SAFE: Classified as LIKELY SAFE AND WELL TOLERABLE in most people. No significant side effects reported with regular use for 3-6 months.
- NO HEAVY METAL RISK: Animal-derived calcium preparation without toxic heavy metals. One of the safest Bhasma preparations.
- TOXICITY STUDY PASSED: All preparations tested with different herbal juices found safe for medicinal use at recommended doses
- 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
- Calcium carbonate (CaCO3): Major component (eggshell, >94%)
- Calcium (Ca): ~38%
- Magnesium (Mg): Trace
- Phosphorus (P): Trace
- Strontium (Sr): Trace
Analytical Methods: XRD, FTIR, ICP-OES
Dosage forms and preparation
Dosage Forms: Bhasma
Standard Dosage: 250–500 mg twice daily
Bioavailability: Good; eggshell calcium carbonate with natural matrix
Optimal Timing: With meals for calcium absorption
Standardized Extract: Calcined eggshell bhasma — natural calcium source
Shelf Life: 12–24 months (organic origin; shorter than mineral bhasmas)
Storage: Airtight, dry container
Marker Compounds: Calcium carbonate (94%), Magnesium carbonate, Calcium phosphate, Strontium
Quality Parameters: Calcium >35%, microbial limits (organic origin), standard bhasma tests
Vehicle (Anupana): Honey or warm milk
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.

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.
