Cryptolepis sanguinolenta is a species of flowering plant in the family Apocynaceae.

[2] Cryptolepis sanguinolenta is a woody climbing shrub with slender branches that can grow up to 8 cm long.

The alkaloid cryptolepine has been isolated from root of the plant and so are two isomers of crytolepine, neocryptolepine and Isocryptolepine.

[5] Roots of the plant are traded as a source of yellow dye for leather and textiles.

[3] In Benin, the latex is used as an antiseptic and in Ghana root extracts are used in treating respiratory infections and malaria.
