Uses
The trunk bark is stimulant and is used as a sudorific in the treatment of fevers. The fresh bark is quite irritating, for which reason it is best to use bark taken from the more mature parts of the trunk, powdered and desiccated. The dose is 1/2–2 grams 2–3 times a day. Its stimulating properties render it useful in colic and in India it is used as a stomachic and digestive. Is seems also to possess diuretic properties.
