Dear.

Allergy can be caused by anything that your body doesn't accept. It's common that previously some things were acceptable but now suddenly acceptance is denied. I had read a case somewhere where the pt. developed allergy to telephone instrument's plastic, cool breeze, smell of some fabrics, latex of bathroom sleepers...What can you do? Can you avoid everything?

Catch is try to enhance your immunity by natural means. Yes that's the only escape or one will end up trying unlimited anti allergics or avoiding hundreds of things in life. Allergy tests are only indicative. Practically can't cover full range of allergens.

For banana, well it can be allergy. There is one antidote prescribed in Ayurveda. Chew and suck cardamomum seeds. It's not going to harm you. At the most it won't effect you. That's all. Your option to try anti allergic toxic drugs is always open.

For common allergy management Ayurveda has mentioned a classical combo named 'Haridra Khand' which cures (CURES) a vast range of allergies without bad effects. It has more than 20 constituents of herbs n minerals.

To my patients' convenience, where they can't find classical Ayurveda products abroad, I advise them to take Cap Neem, Cap Haridra and Sugarcandy powder if not diabetic. This is miniaturized Haridra Khand..not as effective but works.

Hope it helps you. When there is solution, why to worry. All the parties are for mankind's help. We have the option to switch to other when one doesn't work in individual case. Yes herbals are natural and non synthetic, so little slower in action.
