Scientific Summary

Quassia is a tropical shrub or small tree in the Simaroubaceae family whose bark and roots hold a highly bitter substance called quassin. It is traditionally used as a bitter tonic to stimulate digestion, as an antimalarial and antiamoebic treatment, and as an insect repellent because of its antifeedant properties. The herb can cause nausea, vomiting, and gastrointestinal irritation if taken in large amounts, and it is contraindicated for pregnant or breastfeeding women; use under guidance of a qualified practitioner.
