Allergy is a reaction of the body’s immune system to a particular substance that is usually harmless otherwise. The substance to which the body might react varies from person to person and the reaction is also not necessarily similar in everyone. Everyone does not have allergies but the persons who have them may be sensitive to one or more items. There are two main types of allergies: seasonal and perennial. Seasonal allergies occur in a specific season while perennial allergies persist round the year. The exact cause of allergies is not known. Since everyone has different body chemistry, bodies of all the persons living in the same atmosphere react differently to a substance like one person in the house might be allergic to dust while the others might not be. One opinion is that the tendency to be allergic could be inherited but is not true in all cases of allergy.

Homeopathic medicines show miraculos results in allergies, of course they need to be choosen carefuly and are different in every case. there is no common universal medicine for allergies. Every case is treated individualy.
