Last year my wife was at her mother's place where she ate a piece of old stale licorice. It must have had some mold or something in it because she about went viral. They got her to a quick care place where they loaded her up with hospital strength benadryl, not the over the counter stuff. It was strong enough that they had to keep her there for a couple hours to make sure she didn't react to it. It took care of the allergy reaction but it was kind of nasty for a while.
