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.
​Also known as pot marigold or poet's marigold, calendula is different than the common marigold that's usually seen in gardens. Unlike the common marigold calendula is edible and has very little scent. During medieval time in England the calendula herb was commonly used in stews, syrups, and breads. Calendula is also rather easy to start from seed and is able to adapt to many growing conditions making it an ideal herb to grow. The herb is found in many gardens all over the world for subarctic to tropic regions. Now let's take a look at the key medicinal uses that make calendula such a prized herb to have.

Most studies of complementary and alternative medicine in the treatment of cancer pain are of low quality in terms of scientific evidence. Studies of massage therapy have produced mixed results, but overall show some temporary benefit for reducing pain, anxiety, and depression and a very low risk of harm, unless the patient is at risk for bleeding disorders.[34][35] There is weak evidence for a modest benefit from hypnosis, supportive psychotherapy and cognitive therapy. Results about Reiki and touch therapy were inconclusive. The most studied such treatment, acupuncture, has demonstrated no benefit as an adjunct analgesic in cancer pain. The evidence for music therapy is equivocal, and some herbal interventions such as PC-SPES, mistletoe, and saw palmetto are known to be toxic to some cancer patients. The most promising evidence, though still weak, is for mind–body interventions such as biofeedback and relaxation techniques.[36]
Eating a clove or two of fresh garlic a day may indeed keep the doctor away, in part because it has immune-boosting, antibacterial, antiviral, and anti-fungal effects. Many of garlic's therapeutic effects are derived from its sulfur-containing compounds, such as allicin, which are also what give it its characteristic smell. In general, garlic's benefits fall into four main categories:
