�An ethnobotanical survey was conducted in and around Vellore district to study the various medicinal plants used by the people for the treatment of their ailments such as fever, cold, cough, diabetes, jaundice, diarrhoea, rheumatism, snake bite, and headache. The study also covered the methods used in plant extraction, and the dose, duration and mode of application.
Plants have always played a major role in the treatment of human traumas and diseases worldwide (Principe et al., 1991).They have been used as sources of modern drugs, either by providing pure compounds, starting materials for partial synthesis of useful compounds or models for synthesis of new drugs (Hansel and Swian, 1972).According to the World Health Organization (WHO) as much as 80% of world�s population depends on traditional medicine for their primary health care needs (Azaizeh et al., 2003). The knowledge of medicinal plants has been accumulated in the course of many centuries based on different medicinal systems such as Ayurveda, Unani and Siddha. In India it is reported that traditional healers use 2500 plant species and 100 species of plants serve as regular sources of medicine (Pei, 2001).�
Ethnopharmacological information is an important tool in drug discovery (Balandrin et al., 1993).The ethnobotanical survey can bring out many different clues for the development of drugs to treat human diseases. Safe, effective, and inexpensive indigenous remedies are gaining popularity equally among the people of both the urban and rural areas, especially in India and China (Katewa et al., 2004). Ethnobotany and ethnomedical studies are today recognized as the most viable method of identifying new medicinal plants or refocusing on those earlier reported for bioactive constituents. It is interesting to note that most of the drugs derived or originally isolated from higher plants were discovered in an ethnobotanical or ethnomedicinal context. Several studies have revealed that tribal population, not only depend on plant based resources for medicines, food, forage and fuel, but also play a vital role in natural resource management that forms the core aspect of conservation biology (Ignacimuthu et al., 2006). Today, many indigenous herbal remedies remain largely undocumented or recognized as potential forms of treatment and consequently continue to be used by only small groups of indigenous populations. The present work was carried out to explore the medical remedies of some medicinal plants used by the rural people of Vellore district in Tamilnadu for the treatment of human aliments.
Materials and Methods
The entire area of Vellore� District lies between 12�15� to13�15� north latitudes and 78� 20� to79� 50� East latitudes in tamilnadu state.The district is spread over an area of about 6077 km2 and is bounded on the North and Northeast by Tiruvaluvar� District, on the South and Southeast by Kanchipuram District,on the south by Thiruvannamalai district, on the Southwest by Krishnagiri District and on the northwest and north� by Andhra Pradesh state. The district receives an annual rainfall is about 448.8 � 1544.6 mm. The minimum and maximum temperature varies between 26.3� and 38.2�.
�Ethno botanical data were collected according to the methodology suggested by Jain (2001).The ethno botanical data were collected using questionnaire, interviews and discussions in their local tribal people. A totally more than 200 respondents were interviewed, these included males and females that depended on plant as sources of medicines either for self- medication or for treating others. The Flora of Presidency of Madras (Gamble, 1935 and an excursion flora of central Tamilnadu (Matthew, 1991) were used to as certain the nomenclature of the plant species used for identification and authentication of the plants. Folklore medicinal plant are arranged in alphabetical order in Table1 which represents their botanically names followed by the family, vernacular name.
Results and Discussion
In this paper, we focused mainly on plant species reported by the local people in and around the study area for their medicinal uses. Presented data are the general results of the ethnoboanical survey conducted from March 2008 to January 2009. In the present investigation 75 medicinal plants are used for the treatment of various diseases like asthma, piles, diabetes, snake bite, skin disease, ulcer, stomach pain, cough, headache, blood pressure anemia, tumor, rheumatism, eczema, wounds, dysentery, jaundice, antifertility, leprosy, laxative, astringent, urinary disorders,� paralysis, diarrhoea and diuretic etc. Some of them are used as anthelmintic, fever and antiseptic also. Seventy-five plant species belonging to 37 families are reported. The utility lies through their roots, bark, latex, leaves, fruits and seeds. These are taken internally or applied externally in the form of infusion, decoction, paste or powder. Most of the plants used in medicines are either mixed with other ingredients or single. Medicinal plants studied are enumerated arranged alphabetically with their botanical name followed by families� name, local name, parts used and ethnomedicinal uses. Some important medicinal plants needs immediate conservation and their cultivation should be encouraged through which their extinction can be prevented and local village people may also get low-cost cure their disease.
