A survey was embarked upon to document some of the medicinal plant species at the permanent site of Southwestern
University Nigeria, Okun-Owa, Ogun state. The uses of the plants in traditional medicine were also gathered
through group discussion with herbalists and traditional healers in communities around the University. The study
revealed 90 species in 48 angiosperm families and 85 genera. Euphorbiaceae, Asteraceae and Papilionaceae were
the dominant families. The trees and herbs also had more species represented (31% and 28% of the total
enumeration) while the creepers and lianes only had a few (2% and 1% respectively). Many of the listed plants were
however found to be useful in the treatment/management of at least two ailments. Results obtained from the current
study also point out the importance of these plant species in traditional medicine practiced in the surrounding
communities, and suggest that their conservation and sustainable use be encouraged as a way of ensuring their
availability within and outside the study area
