What are these fish and what is “Psoriasis Fish Therapy”?
The scientific name for these amazing silvery-orange fish is garra rufa. Some just call them reddish log suckers or suckermouths , but many are a bit more affectionate, referring to them as “doctor fish” due to their therapeutic effect on skin conditions such as psoriasis, eczema and neurodermatitis.
At first glance these fish do non look very remarkable, but they do a better job than half of the dermatologists I’ve been to!
The “Dr. Fish” are a freshwater fish that belong to the Cyprinidae family (their larger brothers are carp) and normally inhabit the waterways of the Tigris-Euphrates basin in the Middle East. They have a toothless, crescent-shaped mouth and usually grow to around 12cm in length.
Garra Rufa fish normally eat algae, detritus, zooplankton and other bits-and-pieces on the seabed. However, under the right conditions, they also feed on dead and scabby skin. That’s why they’re absolutely perfect for psoriasis.
Using fish to eat away your psoriasis?
For people with normal skin, Garra Rufa are used for heavy-duty exfoliation or a great pedicure, but for people with psoriasis, they can mean much more than that. The plaques that ar characteristic of psoriasis are like banquet tables for these voracious fish! They love banqueting on dead epidermis and after they’re full, there is room for new, healthy skin to grow.
Bon apptit little fish!
The Garra Rufa fish treatment first became popular around the outdoor hotsprings of two small towns in Turkey called Kangal and Sivas, where the first pools were open to the public in 1963.
The high temperature of the water means that there are practically no microorganisms for the fish to eat, so they go for the next best thing – dead, crusty, scabby skin! After the skin has been softened by the warm spa waters, which are kept around 35C / 95F, they have no trouble in munching it off.
Doesn’t it hurt?
The feeling of the nibbling fish is slightly ticklish, like having thousands of toy suction plugs on your skin, and has actually been likened to a pleasurable micromassage. Once you step in, hundreds of garra rufa will swarm around your entire body in an attempt to find that most tastiest of snacks, the psoriatic plaque!
The treatment in Kangal demands that you spend 8 hours a day for a period of 21 days in the pool, so they can guarantee two things; that your skin will be more wrinkled than an old leather handbag, but also spotless
However, this is not a permanent cure. Many people experience remission, or temporary headway of their psoriasis that can last anywhere from a few months to a year, but sooner or later, you will need to feed the fish again.
This all sounds pretty fishy. What are the risks?
The idea of slipping inside a pool with fish that swim from person to person, suck on skin here and there, can be a bit disconcerting. The fish themselves can be hard to sanitize, and 14 states in America, including Washington, New Hampshire and Texas, have banned them. However, the majority haven’t, and they are also legal in the UK.
Many spas treat the water with Ultral Violet Sterilizers to kill the bacteria, and have complex filtering systems to keep the water free from fish waste and food. The chance of getting an infection transmitted by the fish is very low.
The real danger is that some spas have been using cheap Chin Chin fish instead of the real Garra Rufa. The scientific name of these is Tilapia, and they ar sometimes called Kiss Kiss Fish, but be warned, they’re not content with a small peck on the lips!
Chin Chin fish are bred from Chengdu, China and sold to uninformed people as Doctor Fish. The difference is that they have teeth! When they grow beyond 6 centimetres, these teeth can be big and sharp enough to actually pierce the skin and cause bleeding! Look at the fish before jumping in or dipping your toes.
Is there supporting research or scientific evidence that fish therapy or Ichthyotherapy works for psoriasis?
Whilst this fish treatment has non been completely verified, a reputable study can be found in Volume 3 of the Oxford Journal, Evidence Based Complementary and Alternative Medicine.
The conclusions of the study were that fish therapy using Garra Rufa “could provide a viable treatment option for patients with psoriasis vulgaris“.
The photograph on the right was taken in the study to demonstrate the results of Doctor Fish therapy on three different patients after 3 weeks.
The study also noted that the success of the Doctor Fish in treating psoriasis could be down to a combining of the following factors:
- The Kangal spa is situated at a high altitude level of 1650-metres. This means that there is a lot of natural ultraviolet radiation from the sunlight, which acts as phototherapy and is proved to help with psoriasis.
- The hotsprings have a special chemic composition, with high levels of selenium. Selenium deficiency has been joined to psoriasis, so this could be helpful.
- The remotion of skin scales and lesions by the fish helps the penetration of UV rays to the dermis.
- The daily fish bath and micro-massage associated with the fish can help to reduce stress and increase emotional well-being.
Since the treatment is still relatively unknown, it is best to talk to a certified dermatologist before making a decision. It power non right for some, but for others fish therapy has worked wonders for psoriasis.
