Kambo is a healing ritual used mainly in South America. It’s named after the poisonous secretions of the giant monkey frog, or Phyllomedusa bicolor.

The frog secretes the substance as a defense mechanism to kill or subdue animals that try to eat it. Some humans, on the other hand, apply the substance to their body for its alleged health benefits.

The first part of the process involves drinking about a liter of water or cassava soup.

Next, a practitioner will use a burning stick to create a number of small burns on the skin, resulting in blisters. The blistered skin is then scraped off, and the kambo is applied to the wounds.

From the wound, the kambo enters the lymphatic system and bloodstream, where it’s said to race around the body scanning for problems. This usually results in some immediate side effects, especially vomiting.

Once these effects begin to fade, the person will be given water or tea to help flush out the toxins and rehydrate.
