Abstract

The present study deals with the standardization and quality control of the <i>Ayurvedic</i> formulation <i>Darvyadi Pravahi Kvatha</i> following quality control procedures for the finished product. The results of physico-chemical parameters, viz. specific gravity (1.02), total solids (4.83%) and <i>p</i>H (5.54) were found. Microbiological limit test and heavy metals Pb, Cd, As, Hg were also found within the limits set by Ayurvedic Pharmacopiea of India (API).
