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]

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:
