Background: Kambo is the name of a secretion of a tropical frog, the Phyllomedusa bicolor or giant leaf frog from the Amazonian forest, which has been used for centuries by local tribes to enhance their hunter skills. Its first tribal use was described in 1925, and included the first effects after administration of the secretion: nausea and vomiting. Since the end of last century Kambo is introduced in Europe and the USA as a ‘healing’ intervention to cleanse the bodily systems, it is regarded as a ‘detox’ intervention.
