is it curable?

Asthma can not be cured but there are plenty of treatments out there. Other then meds, one thing that helps alot is a tea called "Breathe Easy".

Unfortunatly there's no cure. I don't even know if there's one in the works. For me I know my asthma is 90% better then when I first got it, so maybe you can grow out of it, or it can get better on it's own.

I have it too, but there is no cure right now. Maybe on the horizon there will be one one day

There is no cure for asthma. There are, however, treatments that effectively control it (you have to work with your doctor because some different people react differently to medications and some medications work well for some people but only in combination). Even if you have severe asthma, with the help of a decent doctor, you should be able to control it and live normally.

Asthma is curable by food supplements. My uncle was having Asthma but after using food supplements he left his inhaler now these days he is not using inhaler and he has not asthma now.

From what I understand, asthma is not curable. But there are cases, that you can outgrow it. I myself have asthma before. This was when I was born up to the time when I was 12 years old. I started with tennis lessons and slowly the episodes of my asthma attack was not getting lesser. When I was 14 years up to now that I am 30 plus, I never experience any asthma ever since. Its really great. I do hope that you will also outgrow yours.
