Nom. Vulg. — Kayutana.., Tag.; Salay, Saladay, Vis. 



Uses. — The trunk bark is stimulant and is used as a sudor- 

 ific in the treatment of fevers. The fresh bark is quite irritat- 

 ing, for which reason it is best to use bark taken from the more 

 mature parts of the trunk, powdered and desiccated. The 

 dose is J-2 grams 2-3 times a day. Its stimulating properties 

 render it useful in colic and in India it is used as a sto- 

 machic and digestive. Is seems also to possess diuretic prop- 

 erties.
