Medicinal plants have been curing various turmoils in animals and human from the time immemorial and are considered an intermittently associated and integral part of Indian Traditional Medicinal system. Modern day man-made drugs often show some detrimental effects, but the medicinal herbs are very safe and easy to access. All over the tropical countries, large scale destruction of the forest and wild due to population pressure and over exploitation of medicinal plants have major threat to important bioresources. The studies on propagation of RET plants have received much interest in recent years; but little attention has been given to rare and endangered plants. Regarding the conservation of RET medicinal plants, the knowledge about the mode of propagation is a priority as most of the endemic and RET medicinal plants lacks definite protocol for their propagation and subsequent multiplication. The studies on conservation through conventional propagation are regarded as one of the most effective methodologies for the sustainable supply and thereby enhancing their resources base.
