Recovery of Katha in India- a review

Khair (Acacia catechu Willd) is a deciduous tree that belongs to the family Fabaceae. It yields mainly two products Katha and cutch which have many medicinal benefits and industrial uses. A review was conducted on the recovery of Katha obtained from A catechu. The overall results revealed that the recovery percentage of Katha and cutch ranged from 1.90 to 9.35 and 5 to 17.26 per cent respectively. Most of the work has been done in Uttarakhand state where the mechanical method for extraction of Katha was mostly used. However more investigations on the recovery of Katha and cutch are needed to be conducted in future.
