A new patch may be the answer to helping people with peanut allergies.
CBS reports a new patch is being tested. It is applied to the skin and releases small doses of peanut proteins.
In this way, the patch gradually makes the skin more comfortable with peanuts.
Results show patients treated with the patch gained a higher tolerance for peanuts, and half could eat four peanuts by the end of the year.
Other than slight discomfort, there are no serious side effects.
"The big advantage with this patch is the safety and convenience," said Dr. Hugh Sampson with Mount Sinai in New York. "With the patch we see local reactions but no systemic reactions."
The patch will require more testing before becoming available to the public.
