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]
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.

Chinese medicine has been using cinnamon for medicinal purposes for hundreds of years. It has been the subject of numerous studies to determine its effect on blood glucose levels. A 2011 study has shown that cinnamon, in whole form or extract, helps lower fasting blood glucose levels. More studies are being done, but cinnamon is showing promise for helping to treat diabetes.

CAM therapies include a wide variety of botanicals and nutritional products, such as dietary supplements, herbal supplements, and vitamins. Many of these "natural" products are considered to be safe because they are present in, or produced by, nature. However, that is not true in all cases. In addition, some may affect how well other medicines work in your body. For example, the herb St. John's wort, which some people use for depression, may cause certain anticancer drugs not to work as well as they should.

My wife and I were waiting in one of the examination rooms that were used by the oncology department. It was in a very old part of the university medical complex and the walls between the examination rooms were not soundproof. We could hear a muffled conversation from the next room. Then there was a sudden increase in volume as the patient began to yell at the doctor. It has now been over eighteen years since I heard this man’s statement, and I doubt that I will ever forget it.
There are times when it might be smarter to use an herbal remedy than a pharmaceutical. For example, sometimes an herb offers a safer alternative. Take chamomile: The flowers have been used for centuries as a gentle calmative for young and old alike. It's non-habit-forming and well tolerated, and a study sponsored by the University of Michigan found that chamomile extract had roughly the same efficacy as many prescription sleeping medications when given to adults with insomnia. Likewise, peppermint oil has been shown to be as effective as pharmaceutical drugs for relieving irritable bowel syndrome, but without the ofttimes dangerous side effects. And clinical studies have shown that ginger relieves morning sickness, sage can relieve a sore throat, and hibiscus tea gently lowers blood pressure.
However, patients who use alternative treatments have a poorer survival time, even after controlling for type and stage of disease.[17] In 2017, researchers at Yale School of Medicine published a paper which suggested that people who choose alternative medicine over conventional cancer treatments were more than twice as likely to die within five years of diagnosis. And specifically, in those with breast cancer, people choosing alternative medicine were 5.68 times more likely to die within five years.[18]
