The immune system of each person is unique, and therefore so is the experience of each individual to any substance causing an allergic reaction.
The symptoms of allergy come in many different forms, ranging in their effect from a mild irritant to a severely debilitating chronic condition. About one in four of us has an allergy for all or part of our lives.
Allergies come from a wide number of causes: through a reaction to food or food additives, to pollutants in the air outside or in the home, to chemicals within our surroundings at home or work, or in the many everyday items we use. Asthma and hayfever, eczema, M.E./chronic fatigue syndrome and irritable bowel syndrome are among the conditions now known to be suffered by allergic people. Some reactions may be life threatening: to peanuts or bee stings for example. There are also many instances of children who are cows’ milk-intolerant or who become hyperactive in response to certain food additives.
