It's a very good question and thousands of people who read it, I fact, can reap the benefits out of suggestions given herein, based on the principles of Ayurveda - the nascent science of life.

First of all there is a principle cited in Ayurveda about how to prevent/ cure a disease. It's 'NIDAANPARIVARJAN' (in Sanskrit language) which literally means 'avoidance of the cause'.

Now, in many cases people are not able to change jobs or circumstances are such that they have to continue to remain in such conditions. Here comes the principle of PRAANVAYU (richness of oxygen and fresh air) that is achieved by rythms of deep breathing exercises called PRAANAYAM.

India's Yoga has spread to the World and people who are aware are enjoying the benefits. It enhances immunity, gives strength to fight allergens and extends life as also betters quality of life.

Then there are herbs to naturally support the fight of body against allergens. Simple herbs like Turmeric, Neem, Manjishtha, Giloy, Tulasi (Holy basil) etc. not only counter allergens but detoxifies the blood and also raise natural immunity.

The hitch among beginners is its slow pace of action. Yes naturals are slow as compared to man made synthetic and toxic medicines but then what advantage have these fast drugs given over a time period. No doubt modern synthetics have won in emergency situations and saved lives. But lifestyle disorders and the one you are suffering from needs naturals to support you. These do not have side effects, no interaction with drugs, are safe over prolonged use too. What else you need?

Why not try it. For any further questions please write direct. To my own patients I would suggest to adopt natural Ayurveda medicine. Initially both your current medicine and Ayurveda may be used parallel with some gaps and gradually switch fully if you see advantage.

Hope it helps.
