Indian Journal of Natural Products and Resources Vol. 1 (4), December 2010, pp. 507-511 Some ethnomedicines used by the Tai Ahom of Dibrugarh district, Assam, India Dilip Kalita1* and Bonoranjan Phukan2 1 Department of Botany, Dibru College, Dibrugarh-786 003, Assam, India 2 Institute of Pharmacy, Assam Medical College, Dibrugarh-786 002 Received 8 January 2010; Accepted 16 August 2010 It is well known fact that from the time immemorial, large number of plant species were used by the mankind for the treatment of different kind of diseases. The ethno-medico-botanical folklore of Tai Ahom of Dibrugarh district of Assam is very rich. An attempt has been made to study ethnomedicines used by the Tai Ahom people of the study areas for the treatment of 17 commonly occurring diseases like abdominal pain, abscess, cough, cut-injury, diarrhoea, dysentery, epilepsy, epitaxis, fracture, gastric, inflammation, loosening of teeth, loss of appetite, migraine, sleeplessness, sour in mouth, whooping cough and worms. A total number of 24 medicinally important plant species are reported in this paper. Keywords: Assam, Dibrugarh, Ethnomedicine, Medicinal plants, Tai Ahom. IPC code; Int. cl.8 A61K 36/00 Introduction Assam is situated in the north east corner of India. The state is located between 90º-96° East longitude and 22º-28º North latitude. Dibrugarh district is located in the eastern part of Assam and is situated between 27°5׳28′-27º42׳30′ North latitude and 94º30׳46′-95º29׳8′ East longitude, covering an area of 3301 sq. km. The district is surrounded by Dhemaji district of Assam in the North, Tinsukia district in the East, Sivsagar district and Arunachal Pradesh in the South and Sivsagar district in the West (Fig. 1). The soil of Dibrugarh district is mainly alluvial, deposited by the river Brahmaputra and its tributaries. Relatively long rainy season, high humidity and moderate to high temperature are suitable factors for luxuriant growth of the vegetation in this district. The natural vegetation of the district can be divided into the monsoon forest, with an admixture of evergreen and deciduous forests, the grasslands and swamp growth. The total population of Assam are 2,66,55,528 out of which 33,08,570 are tribal population. In Dibrugarh district there are total 11,85,072 population of which only 88,337 are tribal1. The main tribal ethnic groups of Dibrugarh district are Sonowal kachari, Mishing and Deuris. The Tai Ahom is one of the major ethnic group of Assam and are of Mongoloid in origin, which belong —————— *Correspondent author.

The total Tai Ahom population of Assam are approximately 40,00,000 which are mainly concentrated in upper Assam districts like Dibrugarh, Tinsukia, Lakhimpur, Dhemaji, Sivsagar, Jorhat and Golaghat2. This cultivators ethnic tribe has a vast knowledge about plants as they entirely depend on the plants to meet their day-to-day needs like food, fodder, medicine, cloth, shelter and haj (country liquor). The medicine men and women of this community gathered knowledge about plants usages from their ancestors, who learned this by observing nature and by a long term trial and error experiments. Recently some ethnobotanical works have been carried out by different workers in Dibrugarh district3-7, but unfortunately Tai Ahom group remained Fig. 1 Map of Assam, showing study area 508 INDIAN J NAT PROD RESOUR, DECEMBER 2010 untouched in their study, therefore, to document their knowledge on plants present study was carried out. deposited to the herbarium of Botany department, Dibru College, Dibrugarh, Assam. Methodology The study was conducted between 2008 and 2009. A number of bejes (local medicine men) and bejinis (local medicine women) were contacted and information on medicinal plants was collected. Efforts were made to see the plants in wild and collect plant specimens with their reproductive parts (Plate 1). Herbarium sheets were prepared according to conventional herbarium technique as suggested by Mitra8. Collected plants were identified with the help of Flora of Assam9 and Flora of British India10 and Observations Information on 24 different plant species used traditionally by the Tai Ahom people of Dibrugarh district, Assam is enumerated in the Table 1. Out of these 17 are wild and 7 are cultivated. Traditional and indigenous systems of medicine persist all over the world. Ethnobotanical knowledge of primitive tribes has gained popularity in developed as well as developing countries. Some of the plant species mentioned in this paper are also reported in some earlier works by various authors such as, Plate 1 — Medicine man and some of the medicinal plants used by Tai Ahom of Dibrugarh district KALITA & PHUKAN: ETHNOMEDICINES USED BY TAI AHOM OF DIBRUGARH 509 Table 1 Ethnomedicines used for the treatment of various diseases by the Tai Ahom of Dibrugarh district Name of the disease Abdominal pain Abscess Cough Cut injury Diarrhoea Dysentery Epilepsy Epitaxis Fracture Gastric Inflammation Name of the plant/Family Oxalis corniculata Linn.

The biochemical analysis and pharmacological investigations of plant species used by this tribe will bring some new information of immense scientific values. the cultivation of ethnomedicinal plants at large scale and development of ethnomedicinal garden. Such a step will be helpful in conserving the vast natural resources. Along with this conservation and documentation of ethnomedicinal information is also required for the development of the society. Conclusion The conservation of ethnomedicinal plants wealth requires serious consideration. Lack of awareness among the common people, establishment of small tea garden by cleaning the jungle, change of life style, increase of population, flood, soil erosion, frequent change of course of rivers are the main factors which cause extinction of many ethnomedicinal plants.
