Natural Asthma Remedies: Effective Herbal & Supplement Relief

I feel that it's good to give both sides -- I can say that what works for one person is NOT necessarily apropriate for another. One user indicated that taking vitamin B-12 helped his asthma -- it didn't mine. I take 1 Vitamin B-12 lozenge sub-lingually daily. The dosage is 5000mcg (about 83,000% the RDA). I also take a B-12 + B-Complex vitamin daily, along with the mulit-vitamin - it raises my B-12 intake to about 100,000% of the recommended daily allowance. What has this done for my asthma? Squat!!! (Although, I'm more mentally alert, and I have more energy).
