Computation and Comparison of The Drug Efficacy Indices [Q(VPK)] of certain Ayurvedic Hair Care Formulations

The study conducted in 2015 aimed to predict the effectiveness of certain Ayurvedic hair care formulations, including modern patented and proprietary medicines, by calculating their respective Drug Efficacy Indices [Q(VPK)]. The Drug Efficacy Index is a novel concept proposed as a direct measure of the efficacy of various Ayurvedic formulations. The study was based on Ayurveda, one of the oldest systems of alternative medicines with roots in Rgveda, the oldest monument of human civilization.
