» potential skin irritant; picking the fresh plant can cause skin prickling (Levy and Primack, p. 120). Toxic amounts of alkaloids have been absorbed through the skin. (Duke, pp. 12-13)

» Internal use may result in immediate oral burning, tingling, numbness, and throat constriction; followed by salivation, gastritis, nausea and vomiting. Characteristic tingling may spread over the entire body surface. Dysarthria, ataxia, vertigo, blurred vision, paresthesias and general weakness can follow. Myotoxic effects include stimulation followed by depression of cardiac, smooth and skeletal muscle. Alkaloidal effects on CNS and peripheral nerves produce a curare-like paralysis with labored respirations spreading from upper extremities to lower. Death from cardiac arrhythmia and respiratory failure occurs within 1-8 hours. (A.M.A., p. 20; Dreisbach, p. 434; Levy and Primack, p. 120; Theines and Haley, p. 24)
