I was emailed this question the other day.
QUESTION: what's your opinion on alternative asthma treatments? Like buteyko, herbs, and others?
MY ANSWER: My thinking about alternative asthma therapy is that if it really worked asthma experts would recommend it. I believe there is no outlying proof of their efficacy. However, so long as you work with your doctor, you can most certainly try it and see what works. However, you're also doing so at your own risk. Personally, I've never tried them, so I certainly wouldn't knock them.
