“Doctor fish is the name given to two species of fish: Garra rufa and Cyprinion macrostomus. Other nicknames include nibble fish, kangal fish, physio fish and doctorfishen; in non-medical contexts, Garra rufa is called the reddish log sucker. They live and breed in the outdoor pools of some Turkish spas, where they feed on the skin of patients with psoriasis. The fish are like combfishes in that they only consume the affected and dead areas of the skin, leaving the healthy skin to grow, with the outdoor location of the treatment bringing beneficial effects. The spas are not meant as a curative treatment option, only as a temporary alleviation of symptoms, and patients usually revisit the spas every few months.

In 2006, doctor fish spa resorts opened in Hakone, Japan, and in Umag, Croatia, where the fish are used to clean the bathers at the spa. There are also spas in resorts in China, Belgium, the Netherlands, South Korea, Singapore, Bosnia-Herzegovina, Hungary, Slovakia, India, Thailand, Indonesia, Malaysia, Philippines, Hong Kong, Bucharest (Romania), Barcelona (Spain) and France. In 2008, the first widely known doctor fish pedicure service was opened in the United States.

The practice is banned in several American states and Canadian provinces as cosmetology regulators believe the practice is unsanitary, with the Wall Street Journal claiming that “cosmetology regulations generally mandate that tools need to be discarded or sanitized after each use. But epidermis-eating fish are too expensive to throw away”. The procedure is legal in Quebec, with a few clinics in Montreal”. – Wikipedia
