Nutrients ease COPD symptoms
The lungs contain air tubes that branch into thousands of smaller, thinner tubes that end in bunches of tiny round air sacs. Small blood vessels run through the walls of the air sacs, transferring oxygen from the lungs to the blood, and exchanging carbon dioxide for the lungs to exhale.

In COPD, the air tubes and sacs lose elasticity, become damaged, inflamed or destroyed, and vulnerable to upper respiratory tract infection (URTI). Cigarette smoking is the leading cause of COPD.

In one study, 108 men and women, average age 66, with COPD and URTI took the antibiotic ciprofloxacin for seven days and then added a daily dose of echinacea alone, echinacea along with zinc, selenium and ascorbic acid (vitamin C), or a placebo.

After 14 days, compared to the placebo group, those who took echinacea plus micronutrients had far less severe and much shorter COPD flare-ups.
