In early times mankind developed, through observation and experience, knowledge of the properties of plants as a source of food and medicines. Although food and medical facilities are more readily available to most of the people in our times, still in several underdeveloped and less accessible areas of the country food deficiency and lack of medical facilities are preva-lent. Plant parts like fruits, tubers, flowers, leaves, etc., are consumed as principal or supplementary food and employed as medicines (Sharma and Singh, 2001). India is one of the twelve megadiversity countries in the world and has 17,000 flowering plants. Among the 25 hotspots in the world, the Eastern Himalayas and the Western Ghats are the two hotspots of India. The country possesses a total of 427 tribal communities. The largest proportion of tribes is found in Mizoram (95%), followed by Lakshadweep (93%), Nagaland (88%), Meghalaya (86%) and Arunachal Pradesh (64%) (Dinesh Kumar, 2005; Kala, 2005). Tamil Nadu is situated on the eastern side of the Indian Peninsula. The state has 29 districts and includes 37 tribal communities. They are distrib-uted over various districts. Three major tribal groups of Tamil Nadu are the Valaya or Valaiyans, who live in the hill tracks of Madurai, Dindigul and Tanjore districts, and the Paliyan and Pulayan, living in the Western Ghats. A considerable number of studies have been published on the ethno- botany and ethnomedicine of many tribal groups in different regions of In-dia. Ethnobotanical studies of two groups of Valaiyans, residing in the Velli-malli hills and the Seithur hills (Rajendran et al., 2001; Ganesan and Kesavan, 2003) respectively have already been undertaken. Since such a study regarding the Valaiyans of the Alagarkoil Hills in Tamil Nadu was lacking so far, an attempt has been made to fill this gap. Study area
The area of investigation lies approximately between 77o30’ and 78o20’ lon-gitude and 10o05’ – 10o09’ latitude. The elevation of the area of investiga-tion ranges from 1000 to 3000 feet above sea level. Variations in the altitude and rainfall have a bearing on the vegetation in general. The floristic divi-sions of the area of investigation consist of dry deciduous forest, deciduous thorn forest, evergreen and grasslands. Ethnomedicinal Survey of Alagarkoil Hills The area lies between two hills: the "Vellai malai" to the southern side of the area of investigation and the “Sennamalai” to the northern side. These two hills are situated in the western part of the Alagarkoil hills. Valaiyans can reach Alagarkoil by a short cut route through the hills. Their areas of residence in the Alagarkoil hills are: 1. Vembarali, 2. Barali, 3. Alagapury, 4. Thethampatty, 5. Podugampattu, 6. Pattanampatty. The Valaiyans live in isolated pockets or in small hamlets as labourers and small landowners. The investigation was carried out for 10 months from August 2004 to May 2005. Methodology
Ethnomedicinal information was gathered by contacting the medicine man, the headman and persons with a thorough knowledge of plants. The informa-tion gathered was confirmed by different groups of Valaiyans dwelling in different places of the area of investigation. The methodology of previous workers was adopted (Jains and Goel, 1995). The data was meticulously entered in a field notebook. The voucher specimens were collected and iden-tified by referring to standard floras (Gamble and Fischer, 1957; Matthew, 1981; Nair and Henry 1983; Henry et al., 1987; Henry et al., 1989; Matthew, 1991). All the voucher plants were preserved in the form of herbarium specimens, deposited in the Centre for Research and PG Department of Bot-any, Thiagarajar College (Autonomous), Madurai, Tamil Nadu-625009. Observations
Valaiyans are good herbalists. Plants are used in different forms such as juice extracts, decoctions, pastes, infusions, etc. A juice extract is prepared by grinding the cleaned plants or plant parts with water; the extract is used after having been filtered. A decoction is obtained by boiling the plants or plant parts in water. A paste is made by crushing small parts of a plant with water and mak- An infusion is prepared by soaking the cleaned plant or plant parts in water for a few hours or days; afterwards it is filtered and used.

The tribal and rural population of India is highly dependent on medicinal plants for meeting their healthcare needs. This has attracted the attention of several botanists and plant scientists who directed vigorous research towards the investigation of several medicinal plants; this has resulted in an extensive scientific literature. The present investigation shows that 111 plant species belonging to 100 genera and 49 families are employed for medicinal purposes by a particular tribal population. Out of these, 110 plant species represented Angiosperms, while one plant (Marsilea minuta) belonged to the Pteridophyta. The following 20 plants are employed in skin related disorders: Abrus precatorius, Acalypha indica, Albizia lebbeck, Ammannia baccifera, Ani-someles malabarica, Argemone mexicana, Aristolochia bracteolata, Cassia occidentalis, Cleome aspera, Clerodendrum inerme, Cyanotis arachnoidea, Eclipta prostrata, Hyptis suaveolens, Indigofera tinctoria, Lawsonia inermis, Leonotis nepetaefolia, Mollugo nudicaulis, Notonia grandiflora, Pedalium murex and Wrightia tinctoria. The following 10 plants are used for treating colds and coughing: Alpinia calcarata, Cadaba trifoliata, Eleusine coracana, Erythrina variegata, Euca-lyptus tereticornis, Leucas aspera, Mollugo nudicaulis, Ocimum tenuiflorum, Solanum surattense and Solanum trilobatum. The following 8 plants are employed for the reduction of body heat: Albizia amara, Aloe vera, Cassia auriculata, Cocos nucifera, Cynodon dac- S . G A N E S A N , N . R A M A R P A N D I A N D N . B A N U M A T H Y tylon, Hybanthus enneaspermus, Lawsonia inermis and Trigonella foenum-graecum. Abutilon indicum, Acalypha indica, Cardiospermum halicacabum, Cas- sia obtusa, Dichrostachys cinerea, Eucalyptus tereticornis and Pongamia pinnata are employed in the treatment of various pains related to the legs, the joints, the chest and the throat. Allium sativum, Boerhavia diffusa, Capsicum frutescens, Centella asiat- ica, Cissus quadrangularis, Pergularia daemia and Zaleya decandra are taken for gas trouble. Justicia adhatoda, Eleusine coracana, Evolvulus alsinoides, Hemides- mus indicus and Ocimum canum are utilized in the treatment of fevers. Argemone mexicana, Carissa carandas, Commiphora caudata, Sesbania grandiflora and Solanum nigrum are employed in the treatment of various ulcers. The following plants are administered for stomach related problems such as an upset stomach (Abutilon indicum, Argyreia kleiniana, Cleome gynan-dra and Euphorbia hirta), dysentery (Annona squamosa, Citrus medica, Cocos nucifera and Cuminum cyminum) and stomach pain (Melia azeda-rach, Moringa oleifera and Tephrosia purpurea). The following plants are given for gynaecological problems; Hygrophila auriculata, Piper nigrum, Tephrosia purpurea, Tragia involucrata and Trigonella foenum-graecum. For male fertility Hybanthus enneaspermus and Moringa oleifora are used. Three plants are used to cure piles (Abutilon indicum, Achranthes aspera and Mukia maderaspatana), diabetes (Gymnema sylvestre, Marsilea minuta, Syzygium cumini), and earache (Cleome viscosa, Cymbidium aloifolium, Notonia grandiflora). Employing two plants or one plant only cures the following ailments: jaundice, Coccinia grandis and Phyllanthus amarus; urinary problems, Aerva lanata and Asparagus racemosus; headache, Ocim um canum and Vitex negundo; toothache, Carica papaya and Caesalpinia pulcherima; asthma, Oldenlandia umbellata and Solanum surattense; giddiness, Corian-drum sativum and Zingiber roseum; paralysis, Vernonia cinerea; kidney stones, Tribulus terrestris; tumours, Cataranthus pusillus. The studies on the ethnomedicinal lore of the Seithur hills (Rajendran et al., 2001) revealed the use of 36 plant species belonging to 33 genera dis-tributed over 24 families of flowering plants by the Valaya tribals of Virud-hunagar. Out of these, 7 species were used for scabies and other skin dis-eases, 2 species for jaundice, 4 species for headache, 3 species for fever and one species for diabetes. The present study documented 111 medicinal plant Ethnomedicinal Survey of Alagarkoil Hills species belonging to 100 genera distributed over 48 families. Out of these, 20 species were employed in skin diseases, 2 species in cases of jaundice, 3 species in cases of headache, 5 species in fevers, 3 species in cases of diabe-tes. Nearly 9 plants recorded in the present study were also employed by the Valaiya of Seithur hills. The studies conducted on the ethnomedicinal plants used by the Valai- yans of Vellimalai hills (Ganesan and Kesavan, 2003) indexed 84 angio-spermic plant species belonging to 28 genera distributed over 40 families for the treatment of various disorders, such as wounds, cuts, stomach pain, dia-betes, fever, eczema, dandruff, cold, body heat, poisonous bites. The present study on the ethnobotany of the Valaiyans in the Alagarkoil hills revealed 111 medicinal plants for curing the above-mentioned diseases. Nearly 36 plants reported by the Valaiyans of the Vellimalai hills were also noticed in the present study. The ethnobotanical uses of 161 species of Angiospermic plants distrib- uted over 139 genera representing 60 families were reported from the Thotti-aniackans of Semmalai hills, Tiruchirapalli district (Venkatesan et al, 2005); the uses of 119 plants for medicinal purposes were recorded. In the present study 111 plants out of a total of 167 were categorized as of medicinal value. Among the medicinal plants enumerated, the Thottianaickans also used 55 plants employed by the Valaiyans for treating different kinds of diseases. Ganesan et al. (2004) conducted an ethnobotanical survey of the Lower Palani hills of Tamil Nadu. They enumerated 45 species of plants distributed over 42 genera and belonging to 26 families as of ethnomedicinal value among the Paliyans and Pulayans for the treatment of various ailments. The plants were distributed over the Acanthaceae (4 species), Liliaceae, Cucurbi-taceae, Solanaceae (3 species each), Sapindaceae, Amaryllidaceae, and Eu-phorbiaceae (2 species each). The Pteridophytes were represented by one species (Nephrolepis auriculata) and the remaining 16 families also con-tained one species each. In the present study 111 medicinal plants were recorded. They belonged to the Fabaceae and Lamiaceae (7 species each), Apocynaceae, Asclepiada-ceae Asteraceae Capparaceae, Cucurbitaceae and Liliaceae (4 species each), Acanthaceae, Apiaceae, Mimosaceae and Rubiaceae (3 species each). A number of 12 families counted 2 species each and the remaining 22 families one single species each. The Valaiyans utilize a large number of plants for medicinal and other purposes. A fair number of these species, listed for medicinal purposes by the Valaiyans, were found to be common and already reported from other S . G A N E S A N , N . R A M A R P A N D I A N D N . B A N U M A T H Y places (Karuppusamy, et al., 2000; Rajendran et al., 2001; Ganesan and Kesavan, 2003; Ganesan et al., 2004 and Venkatesan et al., 2005). The uses of certain species have gained importance due to their manifold properties. For example, Abutilon indicum is used for piles and leg pain, Acalypha indica for eczema and chest pain, Mollugo nudicaulis for cold and skin diseases, Notonia grandis for earache and eczema. Sharma and Singh (2000) and Jain and Patole (2001) have also reported similar activities in certain plant species (Cassia fistula and Gloriosa superba) in their studies on ethnobotanical uses of plants. A few species described here as well as by various other authors from different regions as used by various tribes are common, but used for different purposes. Information on some very useful medicines known to the tribal or ethnic communities through the experiences of ages is usually passed on from gen-eration to generation. The tribal ways of life are rapidly breaking off under the impact of improved communication facilities and still more under the various tribal welfare schemes of the government (Mattew, 1981). As the tribal population is gradually adopting modern ways life, their heritage of traditional knowledge of plants will soon be lost forever. For the ethnobotanist it is an urgent task to record for posterity whatever is valuable in the traditions of the tribes, their way of life, and their knowl-edge of plants before all this has disappeared before the close of this century. At the present this valuable diversity is under serious threat due to habitat destruction, overexploitation, shifting cultivation and several anthropogenic and natural pressures. This suggests that the awareness about medicinal plants and their conservation strategy for the sustainability of our ecosystems has to be stimulated. References
