The ethnobotanical uses of South American species of Strychnos L. (Loganiaceae) are reviewed, with the exception of their major rôle in the preparation of curare, which will be dealt with in detail elsewhere.
VELOPMENT: Curare is prepared by boiling the roots, bark and stalks of different plants belonging to the Loganiaceae (Strychnos) and Menispermaceae families (Chondrodendron, Curarea and Abuta).
The history to about 1850 of the muscle-relaxant poison curare is discussed, especially the developments leading to the botanical identification of the plants that yield the alkaloidal active principles: Loganiaceae (Strychnos species) and Menispermaceae (Abuta, Chondrodendron, and Curarea species).
