Erythroxylum (=Erythroxylon) is a genus of tropical flowering plants in the family Erythroxylaceae. Many species contain the drug cocaine; Erythroxylum coca, a native of South America, is the main commercial source of cocaine and of the mild stimulant coca tea. Another species, Erythroxylum vacciniifolium (also known as Catuaba) is used as an aphrodisiac in Brazilian drinks and herbal medicine.
