The human body is constantly exposed to various external influences. Immune system of the body protect itself from harmful effects of these external influences. In certain individuals the immune system becomes hypersensitive and hyper responsive to one or more stimuli which is called allergy. The reasons for developing such allergic immune responses is unclear but in most cases it is constitutional. A person could be allergic to articles in food, air or those which in contact with the skin.

Allergy is commonly manifested on the skin, linings of the respiratory tract, gastrointestinal tract and eyes. Allergy on the skin presents with wheel like eruptions, redness, swelling and itching. Allergy in the respiratory tract leads to itching of the nose, sneezing, watery discharge, dry cough, wheeze and breathlessness. Gastrointestinal allergy presents with abdominal pain, nausea and vomiting.

Homeopathy has a great scope in cases of allergy. Homeopathic medicines are known to increase the resistance through augmentation of the immunity thereby reducing the susceptibility to allergens. Homeopathic medicines are used to treat acute allergic reactions as well as to cure the chronic allergic dispositions.

Remedies such as Apis, Arsenic Alb, Dulcamara, RhusTox, Pulsatilla, Natrum Mur, Sulphur etc. are extremely efficacious in treating allergies. Homeopathic treatment for allergy neither suppresses nor over stimulates the immune system but re adjusts its functioning to the optimum degree. Hence patient responds less intensely on exposure to an allergen, and eventually the allergic response subsides completely.
