Paradise Tree
Simarouba amara
Deep in the forests of Central and South America, healers have long stripped the bark of the paradise tree to brew a bitter decoction for dysentery and stubborn diarrhea, earning it the common name dysentery bark in English-speaking parts of its range. It was also taken as a bitter tonic to settle the stomach and, in some traditions, brewed to ease malarial fevers before quinine bark became widely available. In the twentieth century, that same bitter bark drew the attention of Western science, when researchers isolated a compound from it for early cancer research, a reminder that folk remedy and laboratory curiosity have often walked the same forest path.

Traditional preparations.
A bitter decoction traditionally simmered from the inner bark and taken in small amounts to help settle the digestive system during a bout of diarrhea or dysentery.
Traditionally, about 1 teaspoon of dried, chopped inner bark is simmered gently in 250 ml of water for 10 to 15 minutes, then strained. A small cup was taken, at most once or twice daily, for a few days only.
Safety.
The intensely bitter bark can cause nausea, vomiting, or stomach irritation if taken in excess or over a long period. Avoid during pregnancy and breastfeeding, and it is not appropriate for children.
