Interesting. I'll have to give this one a try. I've had a chronic cough since 2012 and no one can figure out the cause. I've been to four doctors about it (including two specialists), and consulted a medical medium. I've done all different kinds of medications and herbs (recommended by the medium), as well as some herbs I've researched myself. So far, the thing that works best is simple over-the-counter cough medicine and cough drops. I've been scanned, x-rayed, scoped, and blood tested. It's all still a mystery.

I'm getting tested for environmental allergies in a couple of weeks. Maybe that will provide some answers.
