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. 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.
Alternative cancer treatments have not undergone properly conducted, well-designed clinical trials. Among those that have been published, the methodology is often poor. A 2006 systematic review of 214 articles covering 198 clinical trials of alternative cancer treatments concluded that almost none conducted dose-ranging studies, which are necessary to ensure that the patients are being given a useful amount of the treatment. These kinds of treatments appear and vanish frequently, and have throughout history.
Called ALA for short, this vitamin-like substance neutralizes many types of free radicals. A build-up of free radicals, caused in part by high blood sugar, can lead to nerve damage and other problems. ALA may also help muscle cells take up blood sugar. In a German study, a team of scientists had 40 adults take either an ALA supplement or a placebo. At the end of the four-week study, the ALA group had improved their insulin sensitivity 27 percent. The placebo group showed no improvement. Other studies have shown a decrease in nerve pain, numbness, and burning.
Mind-body connection: This idea says that cancer forms because of, or can be controlled through, the person's mental and emotional state. Treatments based on this idea are mind–body interventions. Proponents say that cancer forms because the person is unhappy or stressed, or that a positive attitude can cure cancer after it has formed. A typical claim is that stress, anger, fear, or sadness depresses the immune system, whereas that love, forgiveness, confidence, and happiness cause the immune system to improve, and that this improved immune system will destroy the cancer. This belief that generally boosting the immune system's activity will kill the cancer cells is not supported by any scientific research. In fact, many cancers require the support of an active immune system (especially through inflammation) to establish the tumor microenvironment necessary for a tumor to grow.
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.
