I lead music for a children's choir and noticed my voice getting weaker over the past year, to the point I could no longer sing. Then my speaking voice got raspy as well, almost like laryngitis. Went to the doctor, and he told me to get off Advair immediately, replacing it with a liquid inhaler. That started to improve my voice for about a week, then my voice almost left entirely. I had to get off all asthma meds at that point, but what to do when one grows accustomed to breathing? I am a hiker. The doc knew that. He suggested I focus on more hills to increase my lung capacity. I did my homework I made the following drink when I'd get up in the morning: 1 glass full of ice and some water, about an inch from the top. 1 heaping teaspoon of unsweetened cocoa (caffeine helps asthma and i like chocolate) 1 handful of chopped dates and here is the important ingredient - 1 full dropper of mullein oil, found at health food stores. Mullein opens my airwaves in about 2 minutes. I drink this weird shake and have no problems with my breathing and am off all other asthma meds. Asthma varies in people, as does severity, body type, health history, etc. I hope this may help someone who would like to stop the asthma drugs and still be able to breathe.
