There are many foods that can be used as part of a cancer treatment program. Here are some links that you may find of interest. I think it is very important to remember that cancer is a systemic disease, which will require a systemic approach to cure. I had a friend who had terminal cancer, and he heard that grapefruit was good for treating cancer, so he told his wife to go and by two of them for him. Two grapefruits or a head of broccoli will not cure stage four cancer. Cancer is a serious disease and it requires a serious commitment to bringing about the cure. Such a commitment will require a total lifestyle transformation as you correct the conditions that led to the formation of the cancer.
Another well know spice in the kitchen cinnamon is also known for it's medicinal properties. While not really an herb I still think it's important to list it in our list of herbs and their uses. Cinnamon actually comes from the inner bark of a tree in the laurel family. It's been used for centuries and was a hot commodity for trade in ancient times. In fact during the first century A.D. in Rome cinnamon was 15 times more expensive than silver. The Chinese were probably the first to use cinnamon as a medicinal herb and used it to treat fevers, and diarrhea. In more modern times cinnamon has been found to stabilize blood sugar levels in diabetics, as it has an insulin kind of effect.
