The best and only cure that worked for my lifelong, formerly constant, miserable, life-controlling and debilitating sinus infections is inexpensive Olive Leaf. I make tea from it (boil about a shotglass-full or less of dried leaves in 2 cups water for 20 minutes - it makes one cup of tea). It is also available at health stores in powder, capsule, tincture and supercritical gel cap form. I find tea the most effective, but have had great results with any decent, reputable brand. Olive leaf is known as a wide-spectrum godsend for many, many illnesses and infections from mild to severe to dangerous. I have always found it easy to look up on the web. It is an ancient tried-and-true herb with a fascinating history, reported to give no side effects except a slight lowering of blood pressure and a non-stimulant mild increase in energy (probably due to its elimination of infectious forces in the body). Take it slow at first if you are highly and chronically infected, so you don't get a big healing crisis/die-off reaction. Dosages are available in books and websites, but you can take it every day (I usually do), and it is reported to be impossible to overdose on it -- I feel lightheaded if I take more than 4-6 cups in a day (a very large amount which I'd only use if severely ill) and I am a small individual. It seems to be a best-kept secret, so spread the word and many blessings!
