A condition of unusual sensitivity of one individual to one or more substances (may be inhaled, swallowed or contacted by the skin), which may be harmless or even beneficial to the majority of other individuals. In sensitive individuals, contact with these substances (allergens) can produce a variety of symptoms in varying degrees ranging from slight ADHD to Autism, mild itching to swelling of the tissues and organs, mild runny nose to severe asthmatic attacks, general tiredness or fatigue to severe anaphylaxis. The ingested, inhaled, injected or contacted allergen is capable of alerting the immune system of the body. The frightened and confused immune system then commands the white blood cells to produce immunoglobulins to stimulate the release of neuro-chemical defense forces like histamines from the mast cells. These chemical mediators are released as part of the body’s immune response.
