I'd had two surgeries and was scheduled for another. I had tried all kinds of home remedies, apple cider vinegar, tea tree oil, hydrogen peroxide, I had resorted to pulling them out myself with hemostats, not recommended. A gal at the local heath food store said she used serrapeptase for cysts on her ovaries and suggested I try it. I did and within a month I could breath through my nose after suffering for decades. I shared this with my physician and he was not interested at all, just said if it worked keep using it. I whole heartedly recommend it!
