Medically speaking, this is a prevalent kind of immunotoxicity associated in human beings. Due to the fact that it is allergic in nature, this is a widely known as a hypersensitivity reaction. Hence, it is medically termed as Type IV delayed hypersensitivity reaction which involves the allergic response that is cellular mediated. Aside from that, Allergic Contact Dermatitis is known to rise from the two vital stages known to be the induction phase, where the sensitization is experienced and the other is termed as the anelicitation phase, where the response has been triggered. Most often, the substances that one is allergic to are considered to be harmless such as cotton and the like. Yet, there are persons who have developed hypersensitive reactions to harmless substances.
