As the sixth largest island in the world, Sumatra contains more than 10,000 plant species. A study of traditional knowledge of the local community in Tesso Nilo, focusing on medicinal uses, was conducted in 2003. Research methods included open-ended discussions and direct observation in Situgal village and its surrounding area, Logos Tanah Darat District, Riau Province, Indonesia. To better assess the extractive activities and the utilization of the plant diversity by the local people, an index of cultural significance (ICS) analysis was employed. Research result showed that local people in Situgal still use a number of plants for medicine purposes and rely on ethnobotanical knowledge in their daily life. Ethnobotanical uses were recorded for 86 species belonging to 78 genera and 46 families. Eighty-two species are used for medicinal herbs and the remaining species (4 species) for fish poisons. These species can be used to cure approximately 38 types of illness. By using ICS analysis, the potential value of each species showed that "potalo bumi" (Eurycoma longifolia) is the most important species and well known by local community in Tesso Nilo.
