In this present era of utilization of active principles as a medicine the basic formulations of Bhaishajya Kalpana remain a main source for modern research. The basic formulations are described as Panchavidha Kashaya Kalpanas. Out of these Kashaya Kalpanas, Kwatha Kalpana is an important formulation which is having more potency after Swarasa and Kalka Kalpana. Kashaya has very short shelf life (Saveeryatavadhi). These Kashayas cannot be preserved for longer period. These have to be prepared fresh every day and also the method of preparation is time consuming. Rasakriya (Ghana) is a type of formulation where in the active components can be stored for more days i.e. 3 years (D&C act 161B, w.e.f. 1st April 10). Converting this Kashaya in to Ghana form and then into Ghanavati form may increase the shelf life of the formulation. Along with this it will give a proper shape and dose for the easy administration of medicament. Hence the present research was planned to convert Kushthaghna Mahakashaya Kwatha into Kushthaghna Mahakashaya Ghanavati using standard operating procedure to potentiate active principle in it, and to evaluate shelf life of Kushthaghna Mahakashaya Ghanavati
