[Severe hyponatremia secondary to Phyllomedusa bicolor (Kambó frog) poisoning. Report of one case].

Phyllomedusa bicolor or Kambo is a frog that lives in the Amazon rainforest. It can release through its skin a substance used in healing rituals that are common among South-American tribes, as well as in urban people of America and Europe. We report a 41-year-old female patient who, during a healing ritual consumed ayahuasca (a drink obtained from the mixture of Banisteriopsis caapi, Psychotria viridis and Mimosa hostilis) and 12 hours later received the poison of Kambo Frog (Phyllomedusa bicolor) on superficial right shoulder skin burns.
