Activated charcoal cleanseW
Activated charcoal cleanse

Activated charcoal cleanses, also known as charcoal detoxes, are a pseudoscientific use of a proven medical intervention. Activated charcoal is available in powder, tablet and liquid form. Its proponents claim the use of activated charcoal on a regular basis will detoxify and cleanse the body as well as boost one's energy and brighten the skin. Such claims violate basic principles of chemistry and physiology. There is no medical evidence for any health benefits of cleanses or detoxes via activated charcoal or any other method. Charcoal, when ingested, will absorb vitamins and nutrients as well as prescription medications present in the gastrointestinal tract which can make it dangerous to use unless directed by a medical doctor.

Kambo cleanseW
Kambo cleanse

A Kambo cleansing, also known as a Kambo circle or Kambo ceremony, Kambo, vacina-do-sapo, or sapo, is a purge using skin secretions of the kambô, a species of frog. The effects on humans usually include nausea, vomiting, and diarrhea; Kambo's usage produced several deaths. Kambo, which originated as a folk medicine practice among the Amazon indigenous peoples, is also administered as an alternative medicine treatment in the West, often as a pseudoscientific cleanse or detox. The ceremony involves burning an arm or leg and applying the Kambo secretion directly to the burn. Promoters claim that Kambo helps with several illnesses or injuries. There are ethnographic studies on the use of Kambo in traditional Noke Kuin medicine in the region of the state of Acre, in the Brazilian Amazon.
