We are living in an environment where every moment we take many foreign substances whether useful or useless like pollutants, chemicals, virus, bacteria, allergens into our bodies. Our immune system recognizes them and destroys them if felt harmful for body. The Immune system consists of various immune cells and tissues that works together constantly and consistently to keep us healthy and alive. 

Our environment, society, lifestyle has changed a lot in the last few decades. The spreading of industrialization, urbanization has create a bad impact upon our environment. The pollution level is increasing day by day in the air, water and even in our foods. Most air pollution is created by the people in the form of emission of smokes from the factories, cars, planes etc. Those put severe impact on our body’s immune system. Besides those there are various other factors that also are equally responsible for impairing our immune system such as increase of stress level, living a pressure packed life style, our faulty diet habits, lack of physical activities, suppression of emotions, anger, grieves like psychological expression, suppression of various skin diseases - all those also putting severe impact on our immune system. Thus the healthy function of the immune system is misleading and becoming ineffective or hyperactive at many situation which produces various health problems. 

Inhaling or ingesting of substances like dust, pollens, pet dander is harmful for people whose immune system have been compromised. They can cause allergic reactions to most people. In allergic reaction, the immune cell (B-cell) or B lymphocyte which is a part of immune components produces more antibodies against those substances thinking of a threat for the body. As a result the allergic symptoms are initiated like recurrent sneezing, runny nose, stoppage of nose, itching and redness of eyes and nose etc. 

But at the same time those same substances do not initiate any allergic reaction to many other people. It is because the immune system of those sensitize person reacts adversely to the harmless substances because of their hypersensitive immune function.  So allergies are nothing but the over reaction of the immune system to some specific substances that it misidentifies as harmful. 

Allergies are the most common health issues in these days. It is estimated that 40 to 50% of the total population of India suffers from some form of allergy in his/her lifetime. It is the fourth leading chronic diseases after heart diseases, diabetes, and cancer. The common treatment though checks the symptoms, but cannot offer a long term cure to those allergic patients. The long term cure can only be possible if the hypersensitive nature of the immune system is modified or rectified. 

Homeopathy helps in this regards as because it treats the patient as a whole,  so corrects the hyperactive immune system to its normal form. For any treatment including allergy, homeopathy treatment targets the patient as a whole unlike conventional treatment of specific type treatment. So if a patient takes homeopathy treatment, it cures the root cause of the disease and gives a long-term therapeutic effect in comparison to other conventional treatment. In allergy if a person is taking homeopathy treatment it not only gives relief to his acute present health complaints as well as cure the cause of the allergy to offer a long lasting treatment.
