It's possible that there are other fungi in the lungs other than candida, but things like Candidase do help. Ditto the stuff in the Lung, Bronchial and Sinus Health, which is NAC and Bromelain.
Undecylenic acid is probably the most potent. I just left it after a course, as prescribed by Thorne, and took 5 pills today. It's been a rough day, sinus-wise. A lot of pain. I feel chages around my eyes as well. What I usually feel in the nasal sinuses is an opening and a greater ability to breathe, which is pretty cool. I now get air into areas that I didn't know I could get air into!
