It is native primarily to tropical Africa, extending to South Africa, with a few species in Asia, from southern India to New Guinea and southern China. The name (strophos anthos, "twisted cord flower") derives from the long twisted threadlike segments of the corolla, which in one species (S. preussii) attain a length of 30–35 cm.The genus includes vines, shrubs and small trees. The leaves are opposite or whorled, simple broad lanceolate, 2–20 cm long, with an entire margin.Several of the African tribes used Strophanthus as the principal ingredient in arrow poison. Plants from this genus produce toxic alkaloids and cardiac glycosides g-strophanthin (syn. ouabain), k-strophanthin and e-strophanthin. As ordinarily administered, the drug acts on the heart before influencing any other organ or tissue. Often indeed no other action can be observed. It is used to produce the drug Ouabain which was taken as a cardiac stimulant to treat heart failure, and is similar to the drug Digoxin produced from Digitalis purpurea.Speciesformerly included in genus Strophanthus aambe = Papuechites aambe Strophanthus balansae = Anodendron paniculatum Strophanthus jackianus = Wrightia dubia↑ 1.0 1.1 1.2 1.3"@en }
