It has been estimated that over 100 million Americans are afflicted with some form of allergic disease. Of these, approximately 20 million suffer with allergies severe enough to require serious attention. The allergy may be seasonal hay fever, asthma, eczema, contact dermatitis and other skin eruptions, digestive disturbances, arthritis or respiratory disorders. Many individuals are not treated properly, because their condition is not recognized as being an allergy.

Recent studies have revealed that such illnesses as rheumatic fever, rheumatoid arthritis, scleroderma, dermatomyositis, certain forms of nephritis, anemias and blood and blood vessel diseases resemble hypersensitivity reactions which have been produced in the laboratory. Other diseases involving the glands of internal secretion, particularly the thyroid gland, have now been shown to be allergic in origin.
