Critical review of Shodhana and Marana of Swarnamakshika

In Rasashastra classical books different authors have given different opinions regarding classification of Swarnamakshika. Some considered it as Saklamyaghan (cures all diseases) and Prana of Parada. (Inevitable in various mercurial operations). Hence it was placed under Maharasavarga. Swarnamakshika is grouped under Updhatu of Swarna and is composed of Copper, Iron and Sulphur. Swarnamakshika is considered as potent Rasayana drug and is indicated in diseases like Pandu, Anidra, Apasmara etc. Many Shodhana and Marana procedures have been explained for Swarnamakshika in different classics. A standard Swarnamakshika is prepared conveniently by using Nimbuka Swarasa as Shodhana and Marana media. Marana was done by using Nimbuka Swarasa until Bhasmasiddi Lakshanas found and it took 10 Puta till it attained reddish brown colour. In order to minimize the variability of manufactured product, standardization of Bhasma is must. Swarnamakshika Shodhana procedures remove toxicity from the minerals, metals gems, and poisons and make them safe for consumption; on the other hand if the medicines contain toxicity or any form of impurities, it may cause different health hazards
