The root of the plant cryptolepis (Cryptolepis sanguinolenta (Lindl.) Schlecter, Asclepiadaceae or Periplocaceae)<br> Cryptolepis is derived from the root of Cryptolepis sanguinolenta; syn. C. triangularis N.E. Br., and Pergularia sanguinolenta Lindl. Its common name among the various tribes of Ghana include nibima (among the Twi speaking people), kadze (among the Ewe), and gangamau (among the Hausa). It is also known as Ghana quinine or yellow-dye root. Although the aqueous extract has a bitter taste, this name is probably based on the common use of the plant as a substitute for the anti-malarial alkaloid quinine, and should not be confused with it. Some decades ago, quinine was the drug of choice for the treatment of malaria, and is still in use in areas where there is resistance to chloroquine malaria drugs. Dried cryptolepis has a sweet fragrance. The root, the plant part used for the treatment of malaria, varies from 0.4—6.6. cm long and 0.31—1.4 cm wide and has a bitter taste.
