Title : Comprehensive classical and contemporary review on Kwatha Kalpana(decoction)
Abstract:
Bhaishjya Kalpana (Ayurveda Pharmaceutical Science) is enriched with varying types of dosage forms which are formulated as per the need of the patients. Kwath Kalpana (Decoction) is the most essential and widely used Kalpana as it is the source of most of the secondary dosage forms in Bhaishjya Kalpana. Various important dosage forms such as Avaleha, Ghanasara, Snehapaka, Asavarishta etc. needed Kwatha as a source preparation. Not only in the Bhaishjya Kalpana but in the Rasashashtra also, Kwatha is the most important source for the purpose of various Shodhana, Marana, Bhavana techniques. Kwatha is an important pharmaceutical dosage form in the treatment of various diseases as well as in Panchkarma and surgical practices. It can be used as Anupana or Sahapna form also. So Preparation is the most important and essential aspect which needs to be addressed for achieving quality of Kwatha. Quality of medication can’t be achieved unless and until stringent guidelines are followed. There is a difference of opinion among the ancient seers regarding the addition of water, reduction of water, etc. although it is mentioned in their respective contexts. Uniformity in processing techniques is the need for Ayurveda for better therapeutic value. Various factors such as Proportion of water to be added, reduction volume, consistency of drugs, Particle size of Kwatha Churna, Temperature, vessel to be used, filtration techniques etc affects the quality of Kwatha preparations. Standard operating procedure (SOP) is the most important feature for any pharmaceutical preparation. Typically in the case of Kwatha Kalpana, sometimes vague SOPs are followed hence there is uncertainty regarding its therapeutic efficacy. Recently vast work have been done by researcher to set some guiding parameters to check quality of Kwatha. Amidst these disparities, it is very important to optimize the process of Kwatha and attempt to set guidelines regarding process standardization. Henceforth present research paper take an extensive review on classical and contemporary researches on Kwatha.
