Commercial plaster of Paris is the same mineral calcined and is not godanti bhasma.
Calcium sulphate dihydrate, CaSO4·2H2O. Godanti bhasma is the calcined anhydrite or hemihydrate.
A WAY TO REMEMBER IT
Go-danti is cow's tooth, for the shape and colour of the crystals. Gypsum is from the Greek gypsos, chalk — and gives us plaster of Paris, which is the same mineral calcined.
Godanti bhasma is used in jwara, shirashoola and raktapitta and is one of the mineral preparations a vaidya reaches for most often.

| Status | Characterisation studies exist. Clinical efficacy is not established. |
| The honest gap | Mineral and animal dravya are far less studied than plant dravya, and what study exists is chiefly characterisation and toxicology rather than clinical efficacy. |
Calcium sulphate is poorly absorbed and among the least toxic mineral dravya. The risk is hypercalcaemia only in unusual circumstances.
| Contraindications | Hypercalcaemia. Sarcoidosis and other granulomatous disease. |
| Interactions | Calcium-containing drugs and supplements — additive calcium load. Tetracyclines, fluoroquinolones, levothyroxine and bisphosphonates — calcium binds them. Separate by two hours. |
| Pregnancy and breastfeeding | Not established as safe; calcium itself is unremarkable in pregnancy. |
