of arunachal pradesh and assam was insufficiently documented and authors made efforts to document the healing practices used by mishing community with details of methodology and doses . to cope up

about genuine and reliable traditional healers in the area and came in contact with 11 traditional healers who are engaged in herbal treatment . during course of interaction 55 different herbs and

other diseases . the description of all above mentioned plants are on the basis of ethno medicinal knowledge . plants are used by mishing community in different places on the basis of availability of those plants and the proper knowledge about efficacy of those plants against the particular disease . for safe uses of different medicinal plants , we need randomised clinical trials for some of the manual therapies and further research is need to ascertain the efficacy and safety of several other practices and medicinal plants . we have to develop a proper study about the traditional medicine and the ratio of curative measurement applied to different patients on the use of those plants . the study on such types of documentation is of great importance for north eastern institute of folk medicine in the sense that the institute will get sufficient information on traditional healers and mode administration of medicine for treating ailments on one hand and sufficient tool for proving

public as they are rendering their services to public in very remote places where people are really in need of health services . these traditional healers need to be involved in all sorts of trainings to youngsters as well as refreshing their knowledge with healers of other communities . though they are acquiring and correlating their knowledge with established records and information available with other communities . involving cultivating and using aloe barbadensis and glycyrrhiza glabra is the example and availability of drugs from other climatic zones in the crude drugs markets of major markets in assam strengthen the concept of exchanging knowledge with other communities . the role of government for the existence of this system of medicine should be : 1 . to give due recognition to their contribution and involvement ; 2 . to delineate the specific scope , limit and role of traditional healers in public health promotion ; 3 . to undertake research and development activities ; 4 .
