Rama Devi ABSTRACT Present Study was conducted in the Vallavilai coastal Villages of Kanyakumari district, Tamil Nadu, India to document the Medicinal plant wealth. Taxonomically, a total of 76 plant species belonging to 65 genera and 38 families were recorded. Of these 34 (45%) were herbs, 19 (25%) were shrubs, 13 (17%) were trees and 10 (13%) were climbers/creepers. The plant parts used for the preparation of medicine, whole plants were found to be most frequently used for the preparation of remedies. The mode of preparations is paste, juice, decoction and powder. The medicinal plants of the study area have been used to treat 53 illnesses. The 53 various ailments against which ethnomedicinal treatments have been recorded in the study area can be grouped into 12 major categories of symptomatically and organ-system related diseases/problems. Key words: Ailments, coastal village, Medicinal plants, Vallavilai INTRODUCTION with 2.02 million km exclusive economic In traditional medicine, plants are zone and 0.13 million km continental shelf required as a major component to cure many (Khoshoo 1996) and it covers nine states diseases caused by bacteria, fungi and virus and two union territories. It has numerous in man. The World Health Organization lagoons, beaches, estuaries and mangrove (WHO) has estimated that 80% of the swamps, which is rich in living and non- populations of developing countries still living resources. Tamil Nadu coastal line rely on traditional medicines, mostly plant has a length of about 1076 km, it constitutes drugs, for their primary health care needs. about 15% of the total coastal length of India has rich plant diversity and is India. The coastal zone is an important one among the mega biodiversity countries biogeographically habitats of the Indian of the world. Indians have been using subcontinent (Rodgers and Panwar 1998). medicinal plants since antiquity and the Kanyakumari coastal line has a Ayurvedic methods date back to 5000 B.C. length of about 71.5 km. Coastal vegetation India is rich in its coastal population from contains many species of specific flora and the immemorial time with their traditional thus it is an ecological storehouse rich in knowledge system which deals with the biodiversity and also has high ecological many significant aspects and the health values. The coastal plants are also used for problems of coastal communities. The construction materials, fuel wood and many coastal population has their own herbal other purposes. The characteristic feature of homework to treat various diseases. India the coastal zone is the high population has a coastline of about 7516.6 km long density dominated by fisherman and coir International Journal of Research & Review (www.ijrrjournal.com) 225 Vol.6; Issue: 9; September 2019 S.

These coastal villages Data Collection have a population of 1,48,539 fishermen, Regular field trips were made during forming 19 percent of the total fisherman the study period (November 2018 to March population (7,90,408) in Tamil Nadu. 2019). The information was collected from Hence the present study was the coastal people. A total of 25 were undertaken to document the ethnomedicinal interviewed and obtained information’s, wisdom of Vallavilai village, to assess the mainly concerning their knowledge on medicinal plant diversity of Coastal line and medicine from the plants and their parts, to enumerate information about local names etc. The biological information morphologically useful parts of the of the studied plant material was recorded in medicinal plants to cure various ailments. the field note book.
