Pharmaceutical Analytical Study of Laksha Rasa prepared in two distinct vessels: Emphasis on Ph variation following sequential filtration

Primary preparations in Ayurvedic pharmaceuticals have certain Upakalpana under each. Preparations which share similar principles with its primary preparation can be considered as its Upakalpana. Laksha Rasa is an Upakalpana of Kwatha Kalpana. Laksha Rasa preparation was done in two different Dolayantra - a mud pot and a steel vessel. To one part of coarsely powdered Laksha tied in a Pottali and hung in a Dolayantra, six parts of water was added and heated on mild fire. It was reduced to 1/4th part and was filtered for 21 times. Organoleptic characters and physicochemical parameters were analyzed and on a special note analyze its pH after each filtration. The description of filtering twenty one times might be to reduce the pH of Laksha Rasa. From the study it is understood that filtration here plays a crucial role in lowering the pH, thus potentiating it further.
