Afrikaans names of vrouebossie, bergtee and amarabossie exist for this plant. The use of the plant’s leaves as an infusion in boiling water as a herbal tea to treat bladder infections, venereal diseases and menstrual problems are suggested by these common names (tee = tea; vroue = women; bossie = small bush; the Quassia amara bush is also a Central American plant used for centuries by local populations to treat renal problems (http://portal.unesco.org)). Q. amara is said to produce the bitterest substance found in nature (Wikipedia)!
