Since herbs are food and not medicine, you can take them any time you want. Of course you wouldn’t want to take an energizing herb like ginseng right at bedtime or sedative herbs first thing in the morning. You can decide for yourself if you prefer to take herbs with or without a meal. Do what works best for you. Some herbs work better on an empty stomach. You’ll have to read the label on the supplement bottle to see what is the recommended way of taking them.

The Cherokee Indians used black cohosh as a diuretic and as a remedy for fatigue and tuberculosis. Other native Americans used this herb to treat menstrual irregularities, rheumatism and sore throat. Today, black cohosh is used mainly to reduce the severity of premenopausal and menopausal symptoms, such as excessive sweating, depression and hot flashes.
Many people have been permanently cured of their cancers from these alternative approaches. A cure means that the cancer never comes back. People lived for 20 or 30 years after treatment without a recurrence of cancer. This is in contrast with the modern medical definition of “cure,” which is measured in a five year period. The five year period is a convenient number of years, because the cancers that will be created by exposure to radiation and chemotherapy begin to appear after 5 years. In this way, these secondary cancers can be called a new disease and not a recurrence of 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. 
Hippocrates Health Institute in West Palm Beach, FL. They treat cancer, heart disease, diabetes, obesity, allergies, and more. They use diet, detox, mind/body approaches, nutritional counseling, wheatgrass and juice therapy, nutripuncture, and electro-magnetic treatments. We are not sure if they are set up to treat advanced cancers. www.hippocratesinst.com 800-842-2125
Cancer cells are unable to use ketones for their energy source. They rely on glucose and glutamine for metabolism. Thus, if they do not have access to glucose, they rapidly begin to die. When a person uses the ketogenic diet, they create a condition where there is a reduced level of glucose in the blood and there are elevated levels of ketone bodies. The result is that the cancer cells are denied their primary energy source (starved) while all the healthy cells in the body are nourished by ketones.
Bee Balm was often used by the Native Americans to treat intestinal problems, colic and flatulence. Tea made from this plant was used to induce sweating and break fevers. Bee balm is often used to treat the common cold and sore throat as well. The leaves of this plant are a good source of essential oil that contains thymol. Thymol is an antibiotic and often used as an ingredient in mouthwash.
