Tunget C.L., S. G. Turchen, A. S. Manoguerra, R. F. Clark and D. E. Pudoff. 1994. Sunlight and the plant: a toxic combination: severe phytophotodermatitis from Cneoridium dumosum. Cutis 54(6): 400-402. “A severe case of phytophotodermatitis occurred in a patient who had spent several hours walking through an area densely populated with Cneoridium dumosum. This patient's co-worker experienced a similar reaction after undergoing patch testing of an area of skin and exposing it to sunlight. Voluntary patch testing by one of the authors produced a reaction consistent with the other two cases. Approximately twenty other cases were described by a U.S. Fish and Wildlife Service ranger in students who came into contact with the plant during a field trip with him to Baja California, Mexico. Cneoridium dumosum is a common native bush that grows in the chaparral vegetation zone of southern California and Baja California, Mexico. In a search of Poisindex, Medline, Agris International, and Agricola databases, no previous reports of toxic exposures were found.” |
