Summary
AI-generated from the abstractKambô, the secretion of the Giant Leaf Frog (Phyllomedusa bicolor), is ritually used by Amazonian ethnicities against bad luck in hunting and has spread to Western urban centers, often alongside ayahuasca. A retrospective study of 22 anonymous users (mean age 39 years, 45.5% female) assessed acute and subacute psychological effects with standardized questionnaires. Acutely, participants reported mild to moderate psychological effects without psychedelic-type perceptual or thinking distortions. Persisting effects were predominantly positive and pleasant, with surprisingly high personal and spiritual significance. Subacute and long-term effects overlapped with the 'afterglow' phenomena following serotonergic psychedelics.

Abstract
ABSTRACT Kambô is the name for the secretion of the Giant Leaf Frog (Phyllomedusa bicolor) containing a plethora of bioactive peptides. Originally, it is ritually used by different ethnicities from the Amazon basin as a remedy against bad luck in hunting. In the last twenty years, Kambô has spread to Western urban centers, often associated with the use of ayahuasca. Anecdotal reports claim beneficial effects on wellbeing and different medical and mental health conditions. However, to date it has been controversial if Kambô elicits altered states of consciousness. Here we retrospectively investigated acute and subacute psychological effects of Kambô in a sample of n = 22 anonymous users (n = 22, mean age: 39 years, ± 8.5; 45.5% female), administering standardized questionnaires for the assessment of psychoactive effects. Acutely, participants reported psychological effects which remained on a mild to moderate level, but no psychedelic-type distortions of perception or thinking. In contrast, persisting effects were predominantly described as positive and pleasant, revealing surprisingly high measures of personal and spiritual significance. Subacute and long-term effects showed some overlap with the “afterglow” phenomena that follow the use of serotonergic psychedelics.
