Asthma Treatment Supplement

I use this product to help ward off asthma attacks. I cannot prove its effectiveness, but it feels like it helps, and not using it periodically I feel more sluggish and having low oxygen content. It is worth the small amount of money spent on if nothing more than to provide a good placebo affect.

I love my O+ !!

I love my O+ ... it is so handy to carry around and much more convenient than the full size canisters I usually buy!
