Indian Journal of Traditional Knowledge Vol. 4(1), January 2005, pp. 7-14 Potential of ethnobotanical studies in North East India: An overview B K Dutta and P K Dutta Microbial & Agricultural Ecology and Biodiversity Conservation Laboratory, Department of Ecology & Environmental Sciences, Assam University, Silchar 788 011, Assam Received 27 September 2004; 22 November 2004 North East India has a valuable heritage of herbal remedies. Its rural people and tribals living in remote/forest areas still depend to a great extent on the indigenous systems of medicine/cultivation. So far studies in this regard have been reported from a very limited number of the tribes of North East region, viz. Ler, Mikir, Karbis, Miris, Khasi and Jaintai, Garo, Monpas, Nishi, Apatani, Reangs, etc. A wide range of plants with ethnobotanical value against some very important diseases have been reported but much larger numbers of folk medicines have remained endemic to certain tribal pockets in North East India. Therefore, further detailed studies on the ethnobotanical aspects in the region may provide meaningful ways for the promotion of traditional herbal medicinal plants/land races of crop plants for the benefit of mankind at large. In the present paper, the work that has been reported and the potentials of the ethnobotanical studies with particular reference to biodiversity conservation of the important medicinal/crop plants in the North Eastern region have been highlighted and discussed. Keywords: Ethnobotany, North East India, Medicinal Plants, Biodiversity, Conservation, Tribes IPC Int. Cl.7: A61K35/78, A01K1/00 India is known for its valuable heritage of herbal compounds. Their identification and conservation also medicinal knowledge. Its ethnic people and tribals deserve careful attention. Although some workers1-7 living in the remote forest areas still depend to a great have reported the use of medicinal plants. A detailed extent on the indigenous systems of medicine. The and systematic ethnobotanical study in the North East North East of India constitutes the states of Arunachal region is required as this may provide a meaningful Pradesh, Assam, Manipur, Meghalaya, Mizoram, way for the promotion of the traditional knowledge of Nagaland, Tripura and Sikkim (Fig.1). Though the the herbal medicinal plants/land races of crop plants. North East reflects ecological and cultural contrasts The tribal segment of India's population presents an between the hills and the plains, there are also interesting profile of the country's ethnic diversity. A significant elements of continuity. Available medieval significant proportion of the India's population and modern records indicate interdependence and consists of tribes. There are altogether 427 tribal interaction between the hills and plains. The North communities all over India. Tribes of North East India East is one of the most biodiverse regions in the region are settled within the sub-Himalayan ranges, world. With more than a hundred and fifty tribes Indo-Burma, hills of Nagaland, Manipur, Mizoram speaking as many languages, this region is a melting and Meghalaya plateau and the plains, foothills, N C pot of variegated cultural mosaic of people and races, hills and Karbi Anglong districts of Assam. From the an ethnic tapestry of many hues and shades. The folk anthropological point of view, the tribal people of culture is still vital in this region. Though some of the North East Region of India may conveniently be tribal medicines have been already incorporated in the divided into two broad racial categories, i.e. the Khasi organized systems of medicine, much larger number and Jaintia tribe of Meghalaya who belong to of folk medicines have remained endemic to certain ‘Monkhemar’ culture of Austoic dialect and other tribal pockets in North East India.

Thus, the potentialities of ethnomedicinal approximately 32.4 million people inhabiting the studies in North East should be given the importance region, about 8 million of them constitute the tribals as it can provide us a very effective strategy for the of the hill and plains.
