Reduction of dosage is the prime concern in Ayurveda, because of which many samskara’s have been adopted in order to increase the potency as well as shelf life and reduction of dose. Samskara means to bring a transformation; or to bring a new quality which was not existed earlier. Thus these methods are being adopted to remove the unwanted qualities of the drug and to insert a stipulated quality into it and can be understood as the procedure adopted in which a Drug/Formulation is triturated with a liquid media (Swarasa; Kwatha; Kanji; Ksheera; Mutra etc) till it gets dried.
