Safety Overview
1.Gambir — Botanical Snapshot
Uncaria gambir, commonly known as Gambir, is a robust perennial shrub belonging to the Rubiaceae family, a diverse group renowned for its medicinally active species. This plant typically grows to heights of 1 to 3 meters, thriving in the warm, humid climates of tropical Southeast Asia, specifically being native to Indonesia, Malaysia, and parts of Thailand.
It is commonly found flourishing in rainforest ecosystems and on steep slopes, often at altitudes ranging between 200 and 800 meters above sea level.
The morphology of Uncaria gambir is characterized by its opposite, simple leaves, which are ovate to oblong in shape, measuring approximately 10–15 cm in length and 5–8 cm in width. These leaves possess a distinctive glossy dark green color with entire margins and slightly elongated petioles, contributing to their visual appeal. Gambir produces charming clusters of small, tubular flowers, predominantly yellow to orange in hue, which emerge from the axils of the leaves.
Each flower is about 2.5 cm long and exhibits a unique five-lobed corolla, attracting a variety of pollinators. The plant’s bark is smooth, varying in color from light brown to a reddish-brown, and has a mildly fibrous texture. Notably, the stems of Uncaria gambir contain a yellowish sap, which is the primary part harvested for its significant astringent properties, forming the basis of its traditional and modern applications.
Its cultivation is often integrated into sustainable agroforestry practices within its native range, providing both ecological benefits and a valuable resource for local communities.
