PARADASODHANA (PURIFICATION OF MERCURY) ACCORDING TO AYURVEDA PRAKASHA
Abstract
Rasashastra is a branch of Ayurvedic medicine which deals with formulations containing minerals/metals and significantly Parada. From the fact that the name of this branch has been given after Parada (Rasa in Rasashastra) indicates the emphasis laid by the then health care professionals on the use of Mercury or Rasa or Parada in the use of therapeutics. According to Ayurvedic Formulary of India, mercury is reported to be the widely used heavy metal. But nowadays, modern scientists are concerned with the use of heavy metals in Ayurvedic preparation. According to Ayurveda, before these metals are used for the treatment, purification process should be carried out so that the possibility of adverse effects gets eliminated. Present study deals with the purification of mercury mentioned in Ayurveda prakasha making it therapeutically potent. In Rasa classics, different methods are told for the sodhana of parada. Among them Ashtasamskara is a unique one. If one is not able to do ashtasamskara alone, then the method told in Ayurveda prakasha can be adopted. It includes swedana, mardanas, murchana and urdhwapatanasamskara. Acharya Sharangadhara also opines the same method for paradasodhana. Here total quantity of parada taken was 480 gm and the quantity obtained after sodhana was 173.5 gm.
Key words: Purification of mercury, Ayurveda prakasha, paradasamskara
