Common uses | Gambir is extract of leaves of Uncaria gambier It is sold in the form of small round cakes and is commonly used for chewing together with betel leaves. A little gambir and a pinch of lime is wrapped inside a betle leave and chewed, and upon chewing the secreted juice is swallowed or spitted. It is believed that chewing a betel leave with gambir and lime can promote healthy teeth and gums. In some places where gambir plantation occurred, the leaves are used instead of gambir for chewing. For this purpose, the leaves should be treated first, by boiling with water, pressing and drying to extract the catechine content. Batak people (in Sumatra) used the leaves as ingredients for cigarettes. To extract gambir, leaves were stripped from the twigs and boiled in water for an hour where all the juice was dissolved. The kettle has to be remained on the fire for another 4 hours in order to evaporate surplus water. Then the resulting sludge was put in reservoirs for drying and cut into small cubes. The cubes are then sun dried [201]. It is used for leather tanning and silk dyeing [201]. | |||||
