The Indian Himalayan Region (IHR) has long been a source of medicine for the millions of people of this region including people living in the other parts of India. The pharmaceutical sector in India is using of 280 medicinal plants, of which 175 are found in the IHR [1]. So far, about 8000 species of angiosperms, 44 gymnosperms, and 600 pteridophytes have been reported in the Indian Himalaya [2]. Of these, 1748 species are used as medicinal plants [3], and maximum used as medicines reported from Uttarakhand [4], of these, sixty two species are endemic to the Himalaya [5].Medicinal plants are essential natural resource which constitutes one of the potential sources of new products and bioactive compounds for drug development [6]. Traditional medicinal uses contribute significantly to such drug development. It is estimated that about 60% of the world population and 80% of the population of developing countries rely on traditional medicine for their primary health care needs [7].During recent years medicinal importance important have become very popular [8]. National program on health care have emphasized herbal medicine and fortunately herbal medicinal flora is the richest natural resources in India [8].

The anthropogenic pressures have been identified as the main causes of declining the population of medicinal plants.Today majority of world's population is running behind the herbal medicinal system because of their efficacy, safety and lesser side effects. Due to increasing national and international demand, medicinal plants are facing continuous exploitation from their natural habitat. The uncontrolled exploitation along with several other factors like destruction of habitat, overgrazing, forest fire, grazing and tourism development etc. are leading to deterioration of important plant habitats and selective eradication of commercially more valuable plants [9].Medicinal plants satisfy the million of the ethnic and indigenous people living in tribal and rural sector of India. According to the study [8,10], conducted by the Ministry of Environments and Forest (MOEF), Government of India, tribal communities in India use over 1,0000 wild plants for primary health care.A recent survey from the villages has been carried out and indicating that villagers are taking several resources from the forest including medicinal plants for their basic need, which are used for curing number of diseases. Among the species used by villager, some important species used for curing diseases includes Aegle marmelos (stomach problems), Berberis asiatica (diabetic problems, stone problem), Carissa carandus (diabetes), Emblica officinale (constipation), Eupatorium adenophorum (cut and wound), Juglans regia (killing toothwarm) Litsea glutinosa (recover bone fracture) Mangifera indica (dysentery).
