Fibromyalgia is very similar to Chronic Fatigue Syndrome. It tends to be diagnosed in more women and most often occurs between the ages of 20 and 40. This is roughly the same timing as with Epstein Barr. The symptoms are very much like C. F. S. Two different laboratories have discovered low levels of natural killer cell activity in their fibromyalgia patients. As stated earlier, Olive Leaf Extract stimulates production of phagocytes, the immune system cells. These phagocytes seek and destroy toxins; thus we can conclude that Fibromyalgia patients may well benefit from Olive Leaf Extract.
