The survey was participated by 24 informants, 50% of which had secondary education and 42% are aged 50 years old and above. The ethnobotanical importance of the surveyed plants was quantitatively analyzed in terms of 3 parameters:frequency (F), specificity (S), and reliability (R) in the citation of plant species used for specific ailments. A total of 21 plants from 17 families were surveyed to treat the 16 ailments having a cold and cough as the most cited. The leaves were the commonly used part of the plant, the decoction was the usual mode of preparation, and treatment was usually administered by drinking the herbal infusion (as tea). Of all the cited medicinal plants, 3 species consistently obtained 100% values in F, S and R namely: Lagerstroemia speciosa Linn. (banaba), Piper betle Linn. (buyo), and Citrus maxima (Burm.) Merr.
