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 application 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 malabaricum_. 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.
