My husband was diagnosed with chronic myeloid leukemia, and put on the drug Gleevec. Over the next year, he came down with pneumonia three times. So after doing a little research, I started giving him 5 ounces of essiac tea a day as well as 12,000 mg of vitamin C a day (4 tablets with each meal). It's been three years since he started taking essiac, and he hasn't had pneumonia or even a cold since then. Also he had growths on his saliva gland that completely disappeared without any medical treatment, and his doctor said his leukemia is in remission.
