Industrial use- For centuries local residents of Pali, Rajsamand and Udaipur districts in south Rajasthan have been using stem bark of this plant for tanning lather. Procedure is very simple, stem are cut and dried. Then they are boiled in water for few hours.This solution is then used for tanning of lather. One thing is very surprising that use of plant in tanning is known but no systematic research has been undertaken to understand this process by govt. agencies or universities.
Conclusion – Above paragraphs have clearly elucidated the multiple uses of Cassia plant having wild growth in Aravalli hills of Rajasthan. It is high time govt. undertakes systematic study of Anwal plant, and should also encourage regular cultivation of this plant so its uses can be adopted in other parts of our country.
