The extract is reputed to be among the most bitter substance known. The number of species in the genus is disputed, with authorities claiming anywhere from 1 to 40 -- a bigger range than usual. The genus name, given by Linnaeus, is the Latinized form of the surname of Gramman (or Graman, lit. "Great Man") Kwasi, an 18th-century Guinean who, after being enslaved and transported to Suriname, became renowned as a healer, especially by prescribing quassia for fever, and whose success eventually allowed him to purchase his freedom. The surname Kwasi is probably from an Ashanti dialect, meaning "boy born on Sunday."
