The use of traditional medicine was observed to be wide-spread and prevalent over modern medicine in the study area. In present paper plants for various diseases have been discussed along with their uses, botanical names with family, local names, plant parts used and medicinal preparation along with dosage and mode of administration.

IPC code; Int. cl. 8 A61K 36/00, A61P 7/17, A61P 17/00, A61P 29/00 Introduction In the past decade, there has been renewed attention and interest in the use of traditional medicine globally 1. The World Health Organization (WHO) has pointed out that traditional medicine is an important contributor to its health goals. Today, according to the WHO, as many as 80% of the world's people depend on traditional medicine and in India, 65% of the population in the rural areas use Ayurveda and medicinal plants to help meet their primary health care needs 2. Thus, traditional medicine practices, conserved over decades from old civilizations, can serve as an effective basis for the discovery and development of modern therapeutic drugs. There are considerable economic benefits in the development of indigenous medicines and in the use of medicinal plants for the treatment of various diseases. In a report recently published by the World Bank, Lambert et al, pointed out that preserving and enhancing the plant knowledge and use was equivalent to 'rescuing a global heritage 3. Herbal medicines are comparatively safer than synthetic drugs. Plant-based traditional knowledge has become a recognized tool in search for new sources of drugs 4. The ethnobotanical survey can bring out many different clues for the development of drugs to treat human diseases. Orissa with varied climatic regions has a rich and diverse flora and a mixed floristic composition of aboriginal species used in traditional medicine 5. Although, a good amount of ethnobotanical investigation has been carried out in the southern part of Orissa 6-10, still some areas are left unexplored.

2 Calotropis gigantea tribal districts of Orissa dominated by several primitive tribal communities 11. The district is the homeland of various tribal communities with their sub-tribes found in interior part of the forest. Bonda, Didayi, Koya, Paroja, Bhatoda and Khondh are the primitive tribes found in this district 12. Despite of various developmental activities, the traditional medicine system is quite stable in the study Semecarpus anacardium Location map of Malkangiri district, Orissa area and currently not being replaced by modern allopathic medicine. The present study highlights the use of medicinal plants in traditional medicine of the tribal people in Malkangiri district, Orissa. Study site The Malkangiri district lies between 17º45' to 18º40' N latitude and 81º10' to 82º 00' E longitude. It was earlier a part of undivided Koraput district. Now, it spreads over an area of 5791 sq. kms with a maximum North-South elongation of 137 kms and a maximum East- West elongation of 76 kms. The district is bounded in the East by Koraput district (a portion) of O r i s s a, Vishakhapatnam and East Godavari districts of Lantana camara var. aculeata Cassia tora Tridax procumbens Andhra Pradesh, Bastar district of Chhattisgarh in the West, Koraput district of Orissa in the North and East Godavari and Khammam districts of Andhra Pradesh in the South (Map). The general topography of the area is of broken mountains intercepted by large riverbeds and watercourses. The altitude varies from 400 m near western side to 1200 m on the eastern side with mountain peaks and ridges. Sandy and clay type soil predominate the entire district. The climate of the major portion of the district is influenced by its varied elevation. The minimum and maximum temperatures are 11.2ºC and 44ºC in the month of December and May, respectively (Indian Meteorological Department, Bhubaneswar). Humidity is generally high especially in the monsoon and postmonsoon months. It receives about 1500 mm rainfall annually. Major portion of the annual rainfall is received during Vol 6(5) September-October

3 South-West monsoon between July to September. Half of the portion of the district is covered by dense semievergreen and moist deciduous forests, which is congenial for luxuriant growth of many valuable medicinal plant species. Methodology Several field trips were undertaken for collection of plants during different seasons in 2004 and Information on the plants was gathered through oral interviews of the local tribal people, especially older persons, local medicine men and herbalists. Throughout the interviews, local plant names, usable plant part, preparation method for medicine, application mode and dosage were recorded. All gathered information was cross-checked with people of other villages and other individuals practicing in or near the locality in which the plant material was collected. Also, comparison was made between the information provided by the tribal people and available literature Efforts have been made to select the plants in flowering and fruiting condition and have been provisionally identified by consulting the regional floras Voucher specimens have been deposited in the herbarium of Botany Department, Kakatiya University (KUH), Warangal, Andhra Pradesh. Results and Discussion A total of 34 plant species belonging to 33 genera and 25 families were identified as being used for treatment of approximately 17 ailments or therapeutic indications including headache, toothache and fish poisons (Table 1). Fabaceae, Caesalpiniaceae and Acanthaceae families had the largest number of plants used; and the largest numbers of preparations used were for dysentery and skin diseases. Mostly leaves were used for preparation of medicines for different ailments. Water is used exclusively in the preparation of medicines. Information on Diospyros melanoxylon Roxb., Nyctanthes arbor-tristis Linn., Cassia fistula Linn., Butea monosperma(lam.) Taub., Holarrhena antidysenterica (Linn.) Wall. and Hemidesmus indicus R.Br. are found to be new from this area when compared with the available literature on Indian medicinal plants 6-10, The uses recorded for the first time have been asterisk marked in Table 1.

Conclusion Presently, developing nations, such as India, have an imperative need to systematically document the traditional knowledge on the use of medicinal plants in all autonomous areas or communities, many of which are still largely unexplored. Such documentation is necessary because 434 older people are usually the only custodians of such information and the fast disappearance of traditional cultures and natural resources arising from urbanization and industrialization of such areas suggest that unrecorded information may be lost forever. Documentation of plant materials used in traditional medicine could well benefit general health care and promote forest conservation and ecological research. Such medicinal plants could also be incorporated into primary health care, as people generally feel safer with indigenous cures and also the costs of medicine would be much lesser than the modern drugs.
