[Sp.; = ‘counter-herb’, i.e. one used as an antidote, f. contra- 3 + yerva (now yerba) herb.]
A name given, in general use, to the root-stock and scaly rhizome of species of Dorstenia (D. Contrayerva and D. braziliensis, family Urticaceæ) native to tropical America, used as a stimulant and tonic, and formerly as an antidote to snake-bites. In Jamaica, the name is given to a species of Birthwort (Aristolochia odoratissima), still held in repute as an alexipharmic.
