For toothaches a clove or drop of clove oil on a cotton ball can be placed on the aching tooth. This method should be used sparingly however and do not place the oil on the gum. For nerve pain a diluted oil up to 3% max can be applied to the skin to treat problems such as shingles. In small doses clove powder can be useful for treating things such as nausea, indigestion, and bloating.
The remainder of this article is divided into three sections. The first describes some of the alternative cures for cancer that have been successfully used by many thousands of people. The second section describes some of the steps that you can take to prevent cancer from developing or reoccurring. The third section describes how to avoid exposing yourself to things that will increase your risk for developing cancer.
On the other hand, pathological ketoacidosis is a consequence of other disease conditions such as poorly managed type one diabetes. In this case, the level of ketones will be in the range of 15 to 25 mM. These extremely high levels of ketones can be a serious health problem. The ketogenic diet does not produce this level of ketones. For a thorough discussion of the scientific literature related to the use of the ketogenic diet in cancer treatment I recommend the treatise on the subject by Dr. Thomas N. Seyfried, Cancer as a Metabolic Disease. 
Amygdalin is a glycoside. It consists of a molecule that combined glucose with cyanide. As discussed earlier, cancer cells must have glucose to survive. Thus, when the molecule of amygdalin enters a cancer cell, the molecule breaks apart and releases the cyanide. The cyanide then kills the cancer cell. The cyanide is not released in a healthy normally functioning cell, because a cancer cell contains a special enzyme, which must be present to release the cyanide. Thus amygdalin is harmless to a normal cell.

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.
