This may be TMI, but the wintry weather we've been having has made my feet really dry and itchy (and not too pretty to look at). Soaking my feet in a warm bath brought to mind a story I read a few years ago about pedicures that used fish to nibble away dead skin.
Doctor Fish made a splash in the US news when a salon in Alexandria, Virgina imported 10,000 of the little guys from China in 2008. Since then, a number of states - including California - have banned the use of Garra in pedicures because they cannot be "disinfected" between treatments. The alternative - limiting each fish to a single treatment - would be cost prohibitive and would result in lot of "retired" fish to dispose of in some way.
That unfortunately means I'll have to stick to traditional treatments - pumice and lotion - for my dry heels. My husband claims my feet are too ticklish to withstand 15 minutes of fish nibbling anyway.
Interestingly, one preliminary study found that Garra nibbling - more properly called ichthyotherapy - may be part of an effective treatment for psoriasis. Maybe someday you'll find them in your dermatologist's office, even if they aren't allowed in your local salon.
