Abstract

Rasa Shastra is most important and popular branch of Ayurveda related to Herbo-mineral (Rasaushadhis) preparation techniques with their therapeutic uses. Gandhaka (Sulphur) is a non- metallic solid element found in nature. Kupipakwa, Pottali, Parpati, Khalwiye Rasa Aushadhis containing Gandhaka are very popular due to their instant action even in small dose, tasteless, long shelf life. But Gandhaka must be purified first for preparing different Rasaushadhis so as to eliminate its adverse effects on body. Aims and Objectives-Purification of Gandhaka was carried as per classical reference of Ayurved Prakash and its organoleptic characters were observed. Material and Methods- Different methods by different authors are available for Shodhana of Gandhaka. For present study, Gandhaka was melted with equal amount of Goghrita then poured into vessel containing Godugdha. The same procedure was repeated for 3 times and fresh Godugdha and Goghrita was taken every time. Detailed observations and organoleptic characters were noted during the procedure. Result and Conclusion- Ashuddha Gandhaka was taken 475 g and final purified Gandhaka obtained was 355 gm. Crystalline dark yellow Gandhaka turned into granular and lemon yellow colour, tasteless, Goghruta odour and Snigdha touch after Shodhana.
