An Adelaide pair has been banned from delivering a South American jungle remedy amid fears the treatment can be dangerous.

The process involves using frog poison to heal participants.

Known as Kambo, it is a bizarre amazon ritual that has been practiced in suburban Adelaide.

The so-called ceremonies involve frog poison entering the body through burns on the skin.

It's described as a powerful natural medicine that assists healing and transformation. But after a death in New South Wales, the practice has attracted the attention of authorities who have imposed a ban on Christies Beach practitioners - Carlie J Angel and Brad T Williams.

The pair have been stopped from performing the ceremonies in South Australia and Victoria.

“Anything that produces nausea and vomiting. it has been linked to a death in New South Wales....my concern is about protecting the public,” Health Complaints Commissioner Dr Grant Davies said.

On the couple's business website Two Wolves - One body, they issued a statement saying: "Due to a very sad and unfortunate event associated with Kambo in NSW,  we have been served with an Interim Prohibition Order. The events in NSW were completely unrelated to us, and our hearts go out to everyone involved."

On their Facebook site late today they defended the practice saying it's safe when performed properly.

But South Australia's Health Complaints Commissioner remains concerned about the risks.

“We need to warn the public about it,” Dr Grant Davies said.

“There isn't any evidence to support this, it's not regulated by the TGA, there are some pretty serious side-affects.”

An investigation is currently underway and the interim ban prevents the pair from practicing Kumbo until at least June 26.

“We rely on people coming to us and if people have concerns about Kambo please make contact with us, we're very keen to hear from you,” Dr Davies said.
