Sage also has some medicinal properties like most of its fellow culinary herbs. It has traits that allow it to ease sore throats as well as coughs and colds. Sage was used in Egypt during ancient times to ward off evil, snakebites and to increase the fertility in women and in India sage was used to treat sore throats and indigestion. Sage has been grown in herb gardens and kitchens since medieval times when the Romans introduced it to Europe. Today sage can be found in a wide variety of natural products being sold. This makes sage a great herb for preppers because it means they too can make these natural products. Deodorants are often made from sage because of its antiperspirant properties, and mouthwashes are common due to sage's ability to kill bacteria.
Comfrey's use dates back centuries to at least the time of the ancient Greeks. During the Middle Ages comfrey was a widely cultivated herb found extensively in the gardens of monasteries. Throughout the 1700's and 1800's comfrey was also a popular herb grown in many gardens across Europe as well as America. Sometime during the late 1970's however research revealed that comfrey when taken internally can cause severe liver damage so it has lost popularity and internal use is even banned in many countries. Applications in the from of ointments, poultices, or creams are still considered safe though. Comfrey can still be found growing wild in central Europe, and the eastern United States as well as a few western states.

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. 
Hoxsey Therapy is a mixture of herbs which cures cancer. It began to be sold in 1920s by Mr. Harry Hoxsey. Mr. Hoxsey said that the treatment came from his great-grandfather, who observed a horse with a tumor on its leg cure itself by grazing upon certain wild plants. John Hoxsey gathered these herbs and mixed them with other folk remedies that were used for cancer. The therapy aims to restore physiological normalcy to a disturbed metabolism throughout the body, and to help detoxify the consequences of cancer. At one point, Mr. Harry Hoxsey had 17 clinics located in the United States. He was shut down by the US FDA. A clinic now exists in Mexico.
We live in a world of cancer causing products. They are in conventional food, the water, the air, in our clothing, our automobiles, our homes, the office equipment we use, and in the phones that we use for communication. There is great wisdom in taking reasonable precaution against the factors that can contribute to cancer formation. Sometimes an individual factor may not be a serious risk, but when many factors are combined, they could put a high level of stress on your body and open the door for cancer growth. There are many other factors that could contribute to cancer growth, but the items listed here will be a good starting point.
Cayenne was used by Native Americans as a pain reliever and to halt infections. It was also used for toothache, arthritis and to aid digestion. This herb has anti-bacterial properties, can stimulate blood flow and is rich in vitamins, minerals and antioxidants. Many people consume cayenne to maintain cardiovascular health. Studies suggest that it may be able to reduce triglyceride levels and platelet aggregation in the blood.
When using Aloe you want to be sure not to apply it to any open wounds. Also be careful when processing the leaves. As I mentioned above you want to make use of the clear gel part, and steer clear of the yellow sap that oozes out. While not a big deal when applying to the skin one should be aware of this yellow sap when taking aloe gel orally. This yellow sap is called aloin and if ingested will act as a laxative, if aloin is used for prolonged periods it can lead to depletion of electrolytes and dependence for normal bowl function.
