AS THE CLASSICAL TEXTS AND THE API PRESCRIBE
| Bhasma or pishti | 125–250 mg |

Pravala pishti is the levigated form and is the common one. Used with mukta in a number of pitta yogas.

Dyed bone, glass and reconstituted powder are widely sold as moonga. Corallium species are also under harvest restriction in several jurisdictions and CITES lists some.
From Corallium rubrum and related species — the calcareous skeleton of a colonial marine animal. The skeleton.
A WAY TO REMEMBER IT
Pravala means a young shoot or sprout, for the branching form. Coral is from the Greek korallion, itself probably a borrowing from a Semitic word.
Pravala is used in raktapitta, daha, kasa and in paediatric practice, and appears with mukta in several classical yogas.
Constituents. A product of Corallium rubrum and related species — the calcareous skeleton of a colonial marine animal.
| Status | No clinical evidence establishes an effect beyond its calcium content. |
| 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 carbonate, chiefly. The considerations are calcium load and sourcing legality rather than toxicity.
| Contraindications | Hypercalcaemia. Material of uncertain or illegal origin. |
| Interactions | Tetracyclines, fluoroquinolones, levothyroxine and bisphosphonates — calcium carbonate binds them. Separate by two hours. Calcium supplements — additive load. |
| Pregnancy and breastfeeding | Not established as safe as a medicinal preparation. |
