FAQ
Frequently Asked Questions
Yes, but not as a food. It is used in very small, controlled quantities as a bitter flavouring in some alcoholic beverages (e.g., certain aperitifs) and historically as a medicinal tonic. It is not consumed in significant amounts.
Quassia amara, the most common species, is a tropical plant and requires consistently warm temperatures and high humidity. It may be grown in greenhouses in temperate climates but is not frost-hardy.
In the small doses used for flavouring or in traditional medicine, it is generally considered safe for most adults. However, excessive consumption can cause stomach irritation, vomiting, and other side effects. It should be avoided by pregnant or breastfeeding women. Always consult a professional before using it medicinally.
Both are bitter medicinal barks. Cinchona (the source of quinine) comes from a different family of trees (Rubiaceae) native to South America and was used specifically for treating malaria. Quassia comes from the Simaroubaceae family and was used more as a general bitter tonic, fever reducer, and insecticide.
