Issue Date: Aug-2002
Publisher: NISCAIR-CSIR, India
Abstract: <b>Silviculture</b>- The evergreen tree, Alexandrian Laurel, <b><i>Calophyllum inophyllum</i> Linn.</b> 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. <br><br> <b>Tannin</b>- The increasing demand of <i>Katha</i> for its use in <i>Pan Masala</i>, <i>Gutka</i> and natural dye for hair has necessitated the search of an alternative source. <i>Katha</i> is extracted from the heartwood of a mature tree of <b><i>Acacia catechu</i> Willd.</b> which needs to be cut by <i>Katha</i> entrepreneurs. Another known source for <i>Katha</i> substitute is Gambier, <b><i>Uncaria gambier</i> Roxb.</b> (Hindi - <i>Kath-kutha</i>) which is found in Malaysian region and imported into India.
