There are alternative cancer treatment physicians in Europe who will not treat patients with cancer until they have a dental revision. This means patients must have all the mercury/silver dental fillings replaced with nontoxic materials, and all other metal structures must be removed from their mouths. All root canal teeth must be removed, because they are an ongoing source of toxic waste products from residual bacterial infection. The toxins from root canal teeth stress the entire body. In many situations, mercury, root canals, and metal in the mouth will prevent alternative cancer treatments from being effective. These foreign substances also support the existence of cancer, because of their ability to interfere with the subtle energy systems of the body.
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.
