Aushadha Sevana Kala – According to various acharya

INTRODUCTION

Genuine drugs with the proper time of administration along with the correct route of administration will give an optimum pharmacological effect. Hence in ancient times, Ayurvedic scholars have described the time of administration in a lucid manner in their respective compendia. It is an important principle of ayurvedic pharmacy and pharmaceutics since they are dependent on diurnal variation in tridosha in normal and abnormal conditions.
