INDIAN MEDICINAL PLANTS. 



The active astringent principles of cutch. are a tannin formerly known as 

 catechu-tannic acid and a crystalline body naraedcatechin. The value of 

 cutch as a dyeing and tanning agent depends upon the amount of these two 

 substances, while at the same time they are a measure of its suitability as a 

 medicine. 



According to Professor H. R. Proctor of Leeds, the following are the 

 analyses of extracts from Acacia Catechu : —
