In celebration of this month, the Department is delighted to share some of our amazing student works! โœจ
As we wrap up our series of student research features, we present our final study. ๐ŸŒ๐Ÿ“–
We invite you to read and learn from the insightful work of our student authors!


Ethnobotany examines the interactions between primitive societies and the plants they use for cultural purposes, such as healing various ailments. This study focuses on Adams, Ilocos Norte, which hosts a variety of tribes, including the Yapayao. The research was conducted in three phases: focus group discussion, phytochemical analysis, and bioactivity analysis using mice as model organisms. According to the survey, the Yapayao utilize 27 ethnomedicinal plant species, with inflammation being the most commonly treated medical concern. Among these plants, “garem” (๐˜š๐˜ต๐˜ข๐˜ค๐˜ฉ๐˜บ๐˜ต๐˜ข๐˜ณ๐˜ฑ๐˜ฉ๐˜ฆ๐˜ต๐˜ข ๐˜ซ๐˜ข๐˜ฎ๐˜ข๐˜ช๐˜ค๐˜ฆ๐˜ฏ๐˜ด๐˜ช๐˜ด) and “pantalyon” (๐˜Š๐˜ฉ๐˜ณ๐˜ฐ๐˜ฎ๐˜ฐ๐˜ญ๐˜ข๐˜ฆ๐˜ฏ๐˜ข ๐˜ฐ๐˜ฅ๐˜ฐ๐˜ณ๐˜ข๐˜ต๐˜ข) are particularly notable for their effectiveness against inflammation. Phenols (462.59 ยฑ 19.09, 452.42 ยฑ 35.28 mg GAE/g) and flavonoids (87.32 ยฑ 0.99, 34.91 ยฑ 0.57 mg CE/g) are among the secondary metabolites present in both plants to which the anti-inflammatory activity may be attributed.
