Ras medicines are among the most specialised products in Ayurveda. They contain processed minerals or metals, such as gold, mercury, sulphur, mica or iron compounds, combined with herbs, and they are traditionally prescribed in small doses by experienced practitioners. This guide explains what they are, how they are made, the products in our Ayurvedic ras medicines range and why supervision matters.
What is rasa shastra?
Rasa shastra is the branch of Ayurveda that developed from around the 8th century onwards and deals with preparing minerals and metals for medicinal use. Its name comes from rasa, a classical term for mercury. Practitioners of rasa shastra developed detailed methods of purification (shodhana), incineration (marana) and combination with herbs, to make preparations described as fast-acting in very small doses.
Bhasma, the fine ash-like powders made from minerals and metals, are the building blocks of many ras medicines. Our guide to bhasma and pishti explains how they are made.

Why medical supervision matters
- Small, precise doses: ras medicines are taken in very small amounts, often one tablet or a fraction of a gram.
- Correct preparation is essential: the safety of these medicines depends on proper purification and processing by a licensed manufacturer.
- Not for everyone: they may not suit children, pregnant or breastfeeding women, or people with kidney or liver disease.
- Limited duration: practitioners usually prescribe them for a set period and review.
- Labels say so: many packs state "to be taken under medical supervision". Follow this instruction strictly.
What to check before you buy
- The exact classical name and manufacturer your practitioner has prescribed
- The manufacturer's licence number, batch number and expiry date
- The full composition, including the minerals
- The dose and duration your practitioner has given you
- An intact seal; buy only from a reliable seller
Storage
Keep ras medicines in their original, tightly closed container, in a cool, dry place and out of reach of children. Because doses are so small, accidental swallowing by a child can be serious.
Our recommendation
Take ras medicines only when a qualified Ayurvedic practitioner has prescribed them, at the exact dose and for the stated duration. Buy sealed packs from licensed manufacturers, keep them away from children and tell your doctor about them if you take other medicines.
