Quassia is indigenous to Brazil, Peru, Venezuela, Suriname, Colombia, Argentina, and Guyana. The herb is extremely bitter, the name amargo means “bitter” in Spanish.
The general name, Quassia, comes from a man named Quassi of Surinam who had incredible success using it as a secret ingredient for a particularly bad fever that was running rampant through Surinam. The tall deciduous trees are also known for another interesting trait: no bugs or insects ever bother the trees. This is due to a component in the resin called quassin, which is an incredibly effective insecticide. West Indians in particular use a water extract for an insecticide on their fields. Quassin extract is said to by many times more bitter than quinine, and is used as an ingredient in many medications that would normally contain quinine.
Quassin (gives Quassia its bitterness), phytochemicals quassimarin and simalikalactone D.
Usually taken in the form of an infusion, in capsules, or tincture.
Quassia should not be used during pregnancy. Quassia has been documented to have an antifertility effect in studies and men undergoing fertility treatment or those wishing to have children should avoid using this herb. Large amounts of Quassia can irritate the mucous membrane of the stomach leading to nausea and vomiting.
