Homeopathic Materia Medica by Farrington
In the order of APOCYNACEAE are a number of plants, which we use as medicines. Among these may be mentioned Apocynum cannabinum, and androsemifolium, Gelsemium sempervirens, Vinca minor, Oleander, Nux vomica, Ignatia, Woorari, Alstonia schoiaris, and Spigelia. By some authorities Gelsemium, Nux vomica, Ignatia, Curare and Spigelia have been included in another order, the LOGANIACEAE. This order of plants is very poisonous; some of them raay even cause death.
