Title: Silviculture and Tannin
Issue Date: Aug-2002
Publisher: NISCAIR-CSIR, India
Abstract: Silviculture- The evergreen tree, Alexandrian Laurel, Calophyllum inophyllum Linn. is grown for its oil known as Poonseed oil. The oil is used for soap-making, as an illuminant and applied externally in rheumatism and skin affections. Bark of the tree is also used for various medicinal purposes.

Tannin- The increasing demand of Katha for its use in Pan Masala, Gutka and natural dye for hair has necessitated the search of an alternative source. Katha is extracted from the heartwood of a mature tree of Acacia catechu Willd. which needs to be cut by Katha entrepreneurs. Another known source for Katha substitute is Gambier, Uncaria gambier Roxb. (Hindi - Kath-kutha) which is found in Malaysian region and imported into India.
