Senna can be found all over the tropics. Although they are usually different species, the uses are almost always the same. The leaves and seed pods have powerful purgative and laxitive actions, which have been used to treat constipation, infection, and in traditional Chinese medicine for conditions involving too much heat.
The uses of this herb are somewhat limited, and it is no longer used for purging the body as it was in the past. This action is uncomfortable, and can be dangerous if used incorectly. Now senna is almost purely used for treating constipation short term. Long term use is not recommended under any circumstance.
