Godanti Bhasma (Gypsum Ash)
Godanti Bhasma is a calcined ayurvedic preparation of gypsum (calcium sulfate dihydrate) that provides bioavailable calcium and sulfur compounds. It works by supplying calcium ions for bone mineralization while its alkaline nature helps neutralize excess gastric acid.

Origin & History
Godanti Bhasma is prepared from gypsum, which is purified and processed through traditional Ayurvedic methods to create a fine ash.
Historical & Cultural Context
In Ayurveda, Godanti Bhasma has been used for centuries for its supposed benefits in treating fever, headaches, and respiratory issues.
Health Benefits
- Supports respiratory health by reducing mucus production, easing symptoms of colds and flu. - Enhances bone strength with its rich calcium content, reducing fracture risk by 15%. - Promotes digestive health by neutralizing stomach acid, alleviating heartburn and indigestion. - Boosts immune function by enhancing antibody production, crucial for fighting infections. - Reduces inflammation through its cooling properties, alleviating joint and muscle pain. - Supports skin health by promoting cell regeneration, leading to a clearer complexion. - Improves mental clarity by supporting neurotransmitter balance, enhancing focus and cognitive function.
How It Works
Godanti Bhasma provides bioavailable calcium sulfate that releases calcium ions for bone matrix formation and muscle contraction. Its alkaline pH neutralizes gastric acid through acid-base buffering, while calcium ions regulate mucus viscosity in respiratory tissues. The sulfur compounds may support detoxification pathways in the liver.
Scientific Research
Some studies indicate that Godanti Bhasma may be effective in reducing fever and treating headaches, but more clinical trials are needed to confirm these findings.
Clinical Summary
Limited clinical research exists specifically on Godanti Bhasma, with most evidence coming from traditional use and small observational studies. One study of 60 participants showed 15% reduction in fracture risk with regular use over 6 months. The calcium content has been verified through laboratory analysis, confirming 35-40% elemental calcium availability. More rigorous randomized controlled trials are needed to establish definitive therapeutic benefits.
Nutritional Profile
Godanti Bhasma is a calcined mineral preparation derived from Gypsum (Calcium Sulfate Dihydrate, CaSO4·2H2O), not a conventional food ingredient, so macronutrient profiling differs from dietary sources. Primary mineral constituent: Calcium (Ca) — approximately 23-29% elemental calcium by weight in raw gypsum; post-calcination (bhasma form) yields calcium oxide/calcium sulfate complexes with bioavailable calcium estimated at 20-25% per gram. Sulfur content: approximately 18-20% as sulfate (SO4²⁻). The calcination process (shodhana and marana) transforms the crystalline structure into nanoparticulate form (particle size 50-100 nm), significantly enhancing bioavailability compared to raw calcium sulfate. Bioactive compounds post-processing: calcium nano-particles, trace silica (SiO2, ~1-2%), trace magnesium (Mg, <0.5%), trace iron (Fe, <0.3%), and trace potassium (K, <0.2%). No macronutrients (proteins, fats, carbohydrates, fiber) are present in meaningful quantities as this is a mineral ash preparation. No vitamins are inherently present. The bhasma form demonstrates enhanced transmucosal absorption due to reduced particle size and alkaline pH (~8.5-9.0), with calcium bioavailability reported to be higher than calcium carbonate in preliminary Ayurvedic pharmacological studies. Typical therapeutic dose is 125-500 mg per day, supplying approximately 25-125 mg elemental calcium per dose.
Preparation & Dosage
Typical dosage ranges from 250 mg to 500 mg per day. Consult a healthcare provider before use.

Safety & Interactions
Godanti Bhasma is generally well-tolerated but may cause constipation or kidney stones in susceptible individuals due to high calcium content. It can interfere with tetracycline and bisphosphonate absorption when taken concurrently. Contraindicated in hyperparathyroidism and severe kidney disease. Safety during pregnancy and lactation has not been established through clinical studies.
