How does Quassia work?

Quassia contains chemicals that might increase stomach acid and bile secretions, perhaps accounting for appetite stimulant and digestive effects. Other chemicals may have activity against bacteria, fungi, and mosquito larvae.

Are there safety concerns?

Quassia does not appear to be safe for most people when taken by mouth in medicinal amounts. It can cause side effects such as irritation of the mouth, throat, and digestive tract along with nausea and vomiting. Long-term use can cause vision changes and blindness. In very large doses, it could cause abnormal heart function.

It is not known if quassia is safe for use on the skin (including the scalp) or rectally.

Do not take quassia if:
  • You are pregnant or breast-feeding.
  • You have digestive tract problems or diseases, such as stomach or intestinal ulcers, Crohn's disease, infections, and many other conditions.
