81 PTEROCARPUS MARSUPIUM 



In a chemical point of view kino closely resembles Pegu 

 Catechu derived from Acacia Catechu/ Willd., and Pale Catechu 

 from Uncaria Gambier, Roxb., both of which are described under 

 the plants yielding them. Its essential constituents are catechin 

 or probably pyrocatechin, kino-tannic acid, and kino-red. 



Medical Properties and Use.^-In its action kino is closely allied 

 to catechu, but on account of its comparative insolubility it is less-'' 

 astringent, and is, therefore, commonly regarded as less effective. 

 It may be used, however, in all cases where tannin is indicated, 

 that is, internally in diarrhoea and pyrosis ; in the form of a gargle 

 in relaxed throat ; as an injection in leucorrhcea, &c. ; and as a 

 topical application to indolent and flabby ulcers. 



Kino is also used in the manufacture of wines ; and would be 

 valuable as a tanning and dyeing agent if it could be obtained at a 

 moderate price.
