Two healers have been slapped with temporary bans after allegedly treating Melbourne clients with frog poison from the Amazon suspected of being linked to a woman's death in NSW in March.

Carlie Angel and Brad Williams, trading as Two Wolves - One Body, have been temporarily banned from advertising, offering or providing any general health service in Victoria related to the treatment, which involves the topical application of a secretion taken from South America's giant green monkey tree frog.

Health complaints commissioner Karen Cusack said the treatment, known as kambo, can cause pain, dizziness, shaking, swelling, fainting and severe vomiting.

Her interim orders also ban Ms Angel and Mr Williams, who are based in South Australia, from directing or operating any business in Victoria that involving kambo, while she investigates.
