Kambô, the secretion of the Amazonian Giant Leaf Frog, contains many bioactive peptides and was traditionally used by indigenous Amazonian communities as medicine to improve hunting. In Western urban healing circles, its use has spread over the past 20 years. This retrospective study assessed psychological effects in 22 anonymous users using standardized questionnaires for altered states of consciousness. Acute effects were mild to moderate, with no psychedelic-type perceptual or thinking distortions. Persisting effects were predominantly positive, with high scores on personal and spiritual significance.
Kambô, 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.
