**5.2 Medicinal plants**

*Zingiber spectabile* (Tepus tanah) (**Figure 4**), *Labisia pumilla* (Kacip Fatimah) and *Eurycoma longifolia* (Tongkat Ali) are a few examples of common medicinal plants thriving in Kuala Keniam forests. Many more of the lesser-known plants are no less valuable with virtues waiting to be discovered. *Psycotria malayana*, *Knema glauca* and *Horsfeldia tomentosa*, to name a few, deserve attention from interested researchers searching for bioactive molecules to be turned into yet another important medicinal agent. *Rennellia elliptica* (Segemuk) has been dubbed as the Malaysian ginseng. Decoction of the roots of this plant is drunk for general health booster and also claimed to be anti-diabetic and aphrodisiac.
