Northern South America
Dorstenia contrajerva is a plant species in the family Moraceae. It is native to Northern South America and Central America, and is cultivated elsewhere. The species name "contrajerva" is the Latinized form of the plant's Spanish name, "contrahierba," a name for plants used for treating poisoning and venomous bites and stings, and for which its rootstocks are used in folk medicine (as contrayerva). It is the type species of the Dorstenia genus and was first described by Carl Linnaeus in 1753.
