Scientifc validation of phar- macological activity of age-old drugs used in Ayurveda reinforces faith in the traditional system buy generic metformin 500 mg line, in which plants are selected only on the basis of experience metformin 500mg on-line. This review provides information on Indian herbal drug biodiversity, supply and demand, use of herbal drugs in the pharmaceutical industry and quality control methods required for the modern drug industry. Mostly this increase is in the developing or un- der-developed countries, 80 % of whose population still relies on a traditional system of medicine based on herbal drugs. Goyal are readily available in neighbourhood, cheap, and without side effects, having been time tested. The demand for medicinal plants is continuously increasing not only in developing countries, but also in developed countries as drug, food supplements (nutraceuticals) and cosmetics . Tyler defnes herbal medicines as “crude drugs of vegetable origin utilised for the treatment of diseased state often of a chronic nature or to attain or maintain a condition of improved health” . If we look at the socio-economic scenario of Asian and African countries, modern medicine is neither affordable nor within the reach of many villagers and tribes inhabiting remote areas and deep forests. There are certain pockets in a country like India where the tribal people have no access to mod- ern amenities like roads, telecommunications or electricity, and therefore, these communities rely only on their traditional knowledge of medicine for day-to- day requirements . It is well established that industrialisation has many direct and indirect ef- fects on the human population. Increased stress is the most evident, although this is offset by increased health awareness among the people and better medical facilities. Men learnt to use plants as healers of different ailments with the beginning of civilisation. One of the oldest Pharmacopoeia describing the appearance, properties and use of many plants is by the Greek physician Galen (A. The great civilisations of India, China and North Africa have developed this science to perfection, and written records are available dating back up to 3000 years B. There are many examples where medicines have been obtained from plants known to traditional healers. With the development of modern analytical tools, interest in natural product chemistry has led to the isolation by Serturner of morphine alkaloid from opium, a mixture of plentiful alka- loids. This in turn was obtained from the opium poppy (Papaver somniferum) by processes that have been used for over 5000 years. Quinine isolated from the Cinchona tree had its origin in the Royal household of South American Incas. Long before the frst European explorers arrived, the native people of South America had developed medical systems with complete diagnosis and treatment of various maladies. The leaves of the coca tree have been primarily chewed by Andean people to obtain well-known benefts. In 1860, Carl Koler isolated cocaine from the coca tree, the chemical responsible for its biological activity, and has become infamous as a drug of abuse. Similar are stories of the de- velopment of many modern drugs such as pilocarpine from the alkaloid-rich oil of the zaborandi tree (Pilocarpus zaborandi) used to treat glaucoma, anti- infammatory agents from the pineapple (Ananas comosus), which was used by the American Indians of Guadeloupe. India is a very large country (3,280,483 km2) with diverse geoclimatic zones and biodiversity. Although there are many excellent centres of natural products chemistry, still many plants are yet to be explored for their phytochemical and pharmacological properties, for example Chlorophytum borivilianum. Earlier, Chapter 18 The Indian Herbal Drugs Scenario in Global Perspectives 327 this plant was collected from forests, but it is now cultivated in several thousand hectares and consumed in tonnes, but nothing is known about its chemistry and pharmacology [5,6]. In India we often wake up to our therapeutic wis- dom only after recognition about a plant material or its active ingredient comes from the West . This can be well illustrated by the cases of Rauwolfa ser- pentina  and Withania sonmifera, both of which are used traditionally in the Indian system of medicine, where Indian reports were ignored and the plants attained importance only after publications by Western scientists . In India, it is mainly the central government departments that fund the re- search on medicinal plants; the contribution of private partnership is almost insignifcant. The research and development activity of large traditional Indian pharmaceutical frms is mainly in-house activity. The plants under cultivation are utilised in both the domestic and foreign markets as raw material for drugs and perfumery. These nodal agencies have their own priorities based on their own mandate, and a comprehensive common list of medicinal plants of Indian national priority is yet to be evolved. Ayurveda texts like “Charak Sam- hita” and “Sushruta Samhita” were documented about 1000 years B. It deals elaborately with measures for healthful living during the entire span of life and its various phases. In ad- dition, dealing with principles for maintenance of health, it has also developed Chapter 18 The Indian Herbal Drugs Scenario in Global Perspectives 329 a wide range of therapeutic measures with which to combat illness. These prin- ciples of positive health and therapeutic measures relate to the physical, men- tal, social and spiritual welfare of human beings. In fact, of the 6599 hymns and around 700 prose lines that comprise Atharva Veda, a substantial part relates to the human body, its dis- orders and possible cures, which included recitation of prayers and magical invocations.
