Kambo Ritual: The Frog Poison Practice Linked to Deaths and Growing Health Warnings

A traditional Amazonian practice known as kambo—which involves applying frog secretions to the skin as part of a so-called “cleansing ritual”—has come under renewed global scrutiny after being linked to multiple deaths worldwide.

The ritual, sometimes promoted in Western “wellness” circles as a treatment for physical and mental conditions, is based on the use of toxic secretions from the giant monkey frog (Phyllomedusa bicolor). However, medical experts say there is no scientific evidence that it offers any health benefits.

Kambo originates from Indigenous South American traditions, where it has long been used in spiritual healing practices. During the ceremony, small burns are made on the skin and the frog secretion is applied, often triggering intense vomiting, dizziness, and other severe physical reactions.

Health specialists warn that the substance contains powerful bioactive peptides that can dangerously affect the heart, blood pressure, and nervous system. In some cases, complications such as organ failure, severe dehydration, or fatal cardiac events have been reported.

Authorities in several countries, including Brazil, Australia, and Chile, have either banned or restricted the use of kambo due to safety concerns. In other regions, it remains unregulated or legally accessible despite warnings from medical professionals.

Reports suggest at least six deaths have been linked to kambo in recent years, including cases in the UK, Australia, Italy, Brazil, and Mexico.

Indigenous leaders have also criticised the use of kambo outside traditional contexts, warning that its commercialisation by untrained practitioners poses serious risks to participants.

Health agencies and researchers continue to urge caution, stressing that the ritual should not be considered a safe medical treatment or detox method.
