Now, doctors at New York's Mount Sinai Hospital and 23 other hospitals worldwide are testing what they hope will be a breakthrough treatment. It is a patch that exposes the wearer to small amounts of peanut protein through the skin. Over time, they hope exposure will make the wearer's reaction to peanuts less severe. 

"The protein gets into the outer layer of the skin, is taken up by specialized cells, that then take it to the inner parts of the immune system," said Mount Sinai's Dr. Hugh Sampson. 


This is still in early clinical trials, while they work out the dosage and efficacy. The most impressive part about this patch treatment is that none of the study participants to date have suffered from anaphylaxis due to the patch itself.
