There are different degrees of being allergic to anything, I work for an allergist. Some people get big red welts while I really don't get much of anything and the next person will be sent to the hospital, chest tightness and throat closing. Some people can just take a Benedryl and others need their Epi-pen, which only comes in a dual pack now, FYI. I don't need to take anything, a little baking soda maybe. It's just like with anything else, foods, trees, grasses whatever.
