Abstract

India has a fast growing drug and pharmaceutical industry producing plant based medicines, phyto-pharmaceuticals and over-the-counter products. The country also exports a number of crude drugs and their extracts. The number of plant species yielding raw materials used by the industry on regular basis and/or in substantially large quantities is put at around 340. Among these, 145 occur wild in forests or other forms of natural vegetation, 54 grow as weed, 70 are grown as cash crop for other plant based products, 30 are cultivated as medicinal crop and around 40 are imported from other countries. There has been a tremendous increase in the production of herbal medicines and other items in recent years. This has put great pressure on the raw material resources. Natural population of many medicinal plants has declined to a great extent while a few are at the verge of extinction. A sort of scare prevails among various quarters regarding the decline in the supply of the raw materials or even its discontinuation. Though the fears expressed are quite valid there is a scope not only for damage control but also augmentation of resources assuring continued supplies in future. This paper makes an appraisal of present status of raw material resources and discusses prospects of its development.

Abstract

Proper utilization of medicinal plant resources of India requires a comprehensive approach. There are many issues concerning this area of activity. These include inventorisation , quantitative and techno-economic evaluation , standardization in terms of therapeutic efficacy and augmentation of resources through conservation , domestication and large scale cultivation. The country has been engaged in research and development in this area since long and a lot of information on different aspects is available. There is a need for retrieval and documentation of this information at national level , developing appropriate technologies and creating conditions for gainful utilization of available and developed resources. Such an exercise may go a long way for proper utilization of the resources and taking up further work to fill in the gaps.

Abstract

Sapium sebiferum Roxb., an exotic source of oil seeds has now completely naturalized in Himalayan area. Domestication trials of this plant were carried out through seeds and ischolar_main suckers under two distinct habitats. Propagation occurred fairly well through seeds and ischolar_main suckers. Overall performance of the plants was comparatively better under waterlogged conditions.
