The immune system mistakenly identifies substances—pollens, dust, dander, foods, etc.—as being dangerous and overreacts, setting up a cascade of events that leads to inflammation in the lungs and a narrowing of the air passages.

Bioflavonoids like quercetin and hesperidin enhance vitamin C's effectiveness and increase its absorption. Taking vitamin C with vitamin E may enhance its effects in some cases.
