Quassia is a small tree or shrub native to Brazil that is used for the bitterwood or quassia, its heartwood. The wood and leaves are extremely bitter, the name amargo means "bitter" in Spanish. The tree's resin contains quassin, a bitter-tasting substance (it is, in fact, the bitterest substance found in nature). Extracts of Q. amara bark containing quassinoids are used as insecticides, being particularly useful against aphids on crop plants. West Indians in particular use a water extract for an insecticide on their fields.
