Benadryl is a kind of an antihistamine drug. This kind of medication is widely used against any type of allergy. It usually works short-term.
Histamine itself is a substance released by the cells called Mast cells, which triggers our organisms' allergy reactions. Moreover, histamine plays a vital role in human brain — that's why it's also used to treat motion sickness.
