Significance of Shodhana in Preparation of Kaseesa Dravaka

Introduction: Herbal and mineral preparations are essential in clinical practice worldwide, relying on classical techniques for purification. Shodhana (purification) is the first and fundamental step in purifying metals and minerals. This method eliminates impurities and enhances the material’s properties, making them suitable for further refinement. Kaseesa Drava, a formulation described in the text Rasa Tarangini, which details its preparation and significance in traditional medicine. Kaseesa Dravaka is indicated in Guda Bhramsha (rectal prolapse) and is prepared by adding Shuddha Kaseesa (purified green vitriol) and distilled water in specified ratio.In the present article, the objective of the study is to understand the pharmaceutico-analytical changes in Kaseesa Dravaka based on the different methods of Shodhana of Kaseesa. Methods: The Shodhana of Kaseesa is performed using two distinct methods. According to Rasa Tarangini, Swedana is carried out in Bhringaraja (Eclipta alba) Swarasa, while Bhavana (levigation) with Nimbu (Lemon) Swarasa is prescribed in Brihat Rasa Raja Sundara. These purification techniques result in two different forms of Dravaka: each tailored to the specific method of Shodhana.Results: It is found that dravaka prepared out of Sweditha shuddha kaseesa has dark green semitransparent liquid with sedimentation and some floating particles. The Dravaka prepared out of Bhavitha shuddha kaseesa has light transparent liquid with some sedimentation. Analytically change in pH has been observed in both methods after dravaka prepared. Conclusion: Preparation of Kaseesa dravaka with two different methods of Shoditha kaseesa and change in its nature was observed.
