I always go to natural treatments first. They are effective and fairly inexpensive, overall. In my article http:/artist101.hubpages.com/hub/is-it-cold-or-allergy I suggest many supplements. All have been tried, and are very effective. My favorite one is oil of oregano, as I have had chronic sinus infections all my life, this supplement, along with grapefruit extract, where the cure!!! I had taken numerous antibiotics, without lasting results. I haven't had another sinus infection, since using these supplements. Each of my recommendations, have been tried, and do work. From acidophulus, for irritable bowel syndrome, trytophan for depression, and progesterone cream for menopause, all have worked. To say that I use a specific system, is not true. I research specific conditions, and apply appropriate supplements, and vitamins for optimum results. Magnesium, is the vitamin I recommend for almost every ailment.
