# 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/).

## Names and identification

## Key Phytochemical Constituents

- Calcium (60.83%) - highest among similar preparations
- Calcium oxide (CaO) nanoparticles after calcination
- Copper, zinc, [magnesium](/glossary/compounds-l-o/#magnesium) as trace minerals
- [Strontium](/glossary/compounds-q-t/#strontium) and [phosphorus](/glossary/compounds-o-q/#phosphorus) traces
- Organic matrix [proteins](/glossary/compounds-o-q/#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](/reference/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)

## What do recent clinical trials 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](https://pubmed.ncbi.nlm.nih.gov/30254398/). *Ayu*. PMID [30254398](https://pubmed.ncbi.nlm.nih.gov/30254398/) · [doi:10.4103/ayu.AYU_209_17](https://doi.org/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.

## 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
