Toxicity Profile
Route of ExposureOral (ingestion) (2) ; dermal (2)
Mechanism of ToxicityGrayanotoxins bind to specific sodium ion channels in cell membranes. The grayanotoxins prevent inactivation, leaving excitable cells depolarized. (1)
MetabolismNot Available
Toxicity ValuesNot Available
Lethal DoseNot Available
Carcinogenicity (IARC Classification)No indication of carcinogenicity to humans (not listed by IARC).
Uses/SourcesGrayanotoxins are toxins found in rhododendrons and other plants of the family Ericaceae. (1)
Minimum Risk LevelNot Available
Health EffectsGrayanotoxins affect the nervous system but are not usually fatal. (1)
SymptomsInitial symptoms include excessive salivation, perspiration, vomiting, dizziness, weakness and paresthesia in the extremities and around the mouth, low blood pressure and sinus bradycardia. In higher doses symptoms can include loss of coordination, severe and progressive muscular weakness, bradycardia (and, paradoxically, ventricular tachycardia), and nodal rhythm or Wolff-Parkinson-White syndrome. (1)
TreatmentMedical treatment is not often needed but sometimes atropine therapy, vasopressors and other agents are used to mitigate symptoms. (1)
