Commonly used plant parts were seed (N=67) followed by leaf (N=58), flower (N=32), root (N=31), stem (N=29), fruit (N=25), bark (N=22), whole plant (N=13), latex (N=7), tuber (N=6), rhizome (N=5), bulb (N=1), and cornsilk (N=1).Conclusion: This study concluded that documentation and preservation of biodiversity and its associated knowledge is necessary which could generate further research activities. Ocimum sanctum is the most frequently cited medicinal plant with Relative Frequency Citation (RFC) 0.44 followed by Acorus calamus L. (0.41), Zingiber officinale Roscoe (0.40), Centella asiatica (L.)
