A Short History of Evolution of Indigenous Plants and Medicine System

Abstract

The importance of plants is well known to us. Life and its growth cannot be imagined without plants. Food for our survival is produced by plants and they also create a healthy and eco-friendly environment to live (Sazada et al., 2009).The use of various parts of different medicinal plants to cure specific ailments has been common from ancient times in India. The indigenous system of medicine namely Ayurvedic, Siddha and Unani have been in existence for many centuries. Apart from India, these systems are also prominent in Korea, China, Singapore, West Asia and many other countries. The knowledge of medicinal plants has been inherited traditionally therefore; the utilization of this knowledge has become important for human existence. In the old times, plants were used as remedies for the diseases. The oldest religious book of the World “Rigveda” provides information about the medicinal use of plant “Soma” as a medicinal agent by the Indo-Aryans, which was written between 4000 and 1600 B.C. (Bhattacharjee, 2004).The plant “Soma” is considered to have intoxicating characteristics. This plant is used for sacrificial objectives by Aryans and they also identified its juice as a stimulating beverage (Steiner, 1986). The Aryans also played a vital role in the presentation of therapeutical properties of other medicinal herbs and plants. The knowledge of Aryans about a large number of medicinal plants is demonstrated by the work of Charaka and Sushruta (Kirtikar, 1958).The ancient Indian literature is helpful in driving the current knowledge of using cinchona in malaria, digitalis, strophanthus and physostigma in heart diseases and of quassia as a bitter tonic. The indigenous system of medicine in the Indian sub-continent known as Ayurveda goes back to 700 B.C. and its systematization is attributed mostly to Charaka and Sushruta who have cited about 700 medicinal plants. The book “Sushruta Samhita” compiled in 1000 B.C. includes a comprehensive chapter on herbal therapeutics and contains remarkable information about the use of medicinal plants (Singh and Abrar, 1990).
