Approximately three million Americans are allergic to nuts, and most of those are allergic to peanuts as well. But, according to CBS News, relief may be on the way in the form of the Viaskin Peanut patch being developed by DBV Technologies. The goal of the patch is to slowly familiarize skin cells with peanuts, and it is currently being tested on 221 patients, 50 percent of whom were able to eat up to four peanuts by the end of the year. The company has only run the trial for one year, and it will take a larger trial and several more years before the patch would be released to the public. DBV Technologies is also in the process of developing Viaskin patches for milk allergies and house dust mites as well.
