Uses. — The Hindoos consider the trunk bark an astringent 

 and tonic and use it commonly in diarrhoea and dysentery. In 

 Bombay it has a wide use in veterinary practice as an applica- 

 tion for the sore backs of the domestic cattle. Sarangadhara 

 recommends for diarrhoea and dysentery the infusion of the 

 roasted bark mixed with infusion of Bombax malabavimm. 



Dr. Evers experimented with the powder and an infusion of 

 the bark obtaining a strong diaphoretic action. He obtained 

 the same effect with baths containing the bark and reported 

 successful results in thus treating 24 cases of rheumatism. 

 The dose of the powder was 0.30-1 gram a day in 3 doses ; 

 the infusion (30 grams bark to 300 boiling water), 90 grams a 

 day in 3 doses. Combined with opium it had more pronounced 

 diaphoretic effects than the compounds of opium and ipecac. 

 The plant possesses no febrifuge properties.
