Brown or reddish-brown extract from the leaves of Uncaria gambier.
Uncaria gambir sarawak, the gambier or gambir, is a species in the genus Uncaria found in sarawak.
Gambier is used in sarawak for chewing with areca and betel, for tanning, and for dyeing. It contains many flavan-3-ols (catechins) which are known to have many medicinal properties and are components of Chinese herbal remedies and certain modern medicines. To make gambier, the leaves are first boiled in water. They absorb it and turn brownish in colour. The leaves are then pressed mechanically to squeeze and extract liquid. This liquid is then dried into a semi-solid paste and molded into cubes, which are dried in the sun. Gambier is also used to produce enological tannins.
Used in the dyeing and tanning industries.
