Rhus toxicodendron

North American Eastern Poison Ivy - Toxicodendron radicans - was introduced to our Materia Medica by Hahnemann as Rhus radicans, the binomial name proposed by Linnaeus, with toxicologic observations and formal Prüfungen reported in his Materia Medica Pura. T.F. Allen reported 98 authorities in his Encyclopedia of Pure Materia Medica, combining reports published under the names Rhus radicans and Rhus toxicodendron.
