From the Introduction:
Ayurvedic Pharmacopoeia of India consists of two parts Part I and Part II the former dealing with raw material of single drugs used by the Ayurvedic, Siddha and Unani Pharmaceutical manufacturers and the latter including the classical compound formulations.
A part of this programme is the preparation of an illustrated guidance manual as a companion to each of the volume of the single drugs. This would greatly enhance the understanding of the drug descriptions given in the monographs, by the stake holders, particularly in regulatory laboratories of the State Governments. As a consequence, a small Committee constituted by the APC has compiled a set of photographs, macroscopic and microscopic drawings of the drug material appearing in the volume V of Part I of the API. Similarly each of the volumes in Part I of the API would have a companion volume of photographs of compound formulations appearing in different volumes of the API-Part I illustrating the feature of the tissue debris isolated from the formulations amenable to such a treatment, so that the ingredients maybe identified.
This publication deals with the crude drugs included in volume V of Part I, and the illustrations represent the diagnostic features described in the monographs therein. These have been prepared from the anatomical studies carried out on authentic crude drugs by the collaborators to whom the task was assigned. However, a few photographs of plants and herbarium sheets taken from other publication and institutions are also included with due acknowledgement to the sources.
