Reiki
Key Points
- Reiki is a Japanese technique for stress reduction and relaxation.
- Practitioners consider restricted flow of Ki (energy) in the body to be the precursor to disease.
- In cancer care, Reiki tends to be used as a palliative or supportive therapy.
- Noting the methodological limitations highlighted in reviews, we list available research documenting effects of Reiki in people with cancer.
- Reiki is not believed to have the potential to cause serious direct harm

The International Center for Reiki Training describes Reiki:
A Japanese technique for stress reduction and relaxation that also promotes healing. It is administered by "laying on hands" and is based on the idea that an unseen "life force energy" flows through us and is what causes us to be alive. If one's "life force energy" is low, then we are more likely to get sick or feel stress, and if it is high, we are more capable of being happy and healthy.
“The word Reiki is made of two Japanese words:
- Rei which means ‘God's Wisdom or the Higher Power’
- Ki which is ‘life force energy’
Reiki is compatible with all other healing modalities—conventional and alternative—and is not a religious practice.

Reiki master teachers trace their lineage back to their founder Michao Usui, who founded the practice in Japan in the late 1800s. The practice found its way to Hawaii in the 1930s and was brought to US mainland in the 1970s.
Reiki, in the tradition of the Japanese teacher (sensei), is passed on from master to student through attunement, an initiation ceremony using laying on of hands. This attunement ceremony is supposed to open the student’s energy channels, thus enhancing universal life energy flow for treating others and oneself.
Reiki training has evolved with iterations over the years. No official credentialing organization exists for Reiki practitioners, although Reiki courses are available, often from organizations offering professional continuing education credits from approved provider organizations. For more detailed description of Reiki training, refer to Potter’s article: Energy therapies in advanced practice oncology: an evidence-informed practice approach.
In cancer care, Reiki tends to be used as a palliative or supportive therapy. Practitioners consider restricted flow of Ki (energy) in the body to be the precursor to disease. They claim that Reiki unrestricts the flow of Ki (energy) in the body. Recipients report deep relaxation, relief from anxiety and pain, and an improved sense of well-being.
Clinical Practice Guidelines
2009 evidence-based clinical practice guidelines for integrative oncology conclude that therapies based on a philosophy of bioenergy fields are safe and may provide some benefit for reducing stress and enhancing quality of life. Only limited evidence is available regarding their efficacy for symptom management, including reducing pain and fatigue. The Society for Integrative Oncology gives a strong recommendation for these therapies:
- For reducing anxiety: grade 1B (strong recommendation, moderate-quality evidence)
- For pain, fatigue, and other symptom management: grade 1C (strong recommendation, low or very low quality evidence)

The Society for Integrative Oncology 2017 clinical practice guidelines for patients with breast cancer state that as of spring 2017, there was insufficient evidence to form a clinical recommendation for using Reiki for anxiety/stress reduction.
Managing Side Effects and Promoting Wellness
Managing or relieving side effects or symptoms, reducing treatment toxicity, supporting quality of life or promoting general well-being
According to CAM-Cancer “Only a few studies of Reiki have been published; most have methodological limitations and are thus not conclusive.”
TRC's Natural Medicines Database also concludes that although insufficient reliable evidence is available to rate Reiki’s effectiveness, preliminary clinical studies suggest that the therapy can have positive effects, including reducing fatigue, improving quality of life, reducing pain, improving depression and improving stress.

Noting the methodological limitations highlighted in reviews, we list available research documenting effects of Reiki in people with cancer:
Reviews:
- A 2006 review found short-term pain relief and improved quality of life.
- A 2007 review of Reiki found positive outcomes for pain management and possible effects on biological markers.
- A 2014 review of Reiki used for all health conditions, including cancer, found that in four randomized controlled trials, Reiki may reduce pain and anxiety..
Studies:
- A 2003 trial found Reiki provided short-term pain relief and improved quality of life compared to rest, although during the seven days of the study, treatment was not associated with reduced use of opioids.
- A 2004 study found Reiki Improved depression and stress.
- A 2007 study found reduced feelings of fatigue and improved quality of life during cancer chemotherapy..
- A 2011 pilot study of patients being treated with radiation therapy for prostate cancer found a positive trend for improvement in anxiety after Reiki treatment.
- A 2011 randomized controlled trial found that although Reiki therapy was statistically significant in raising the comfort and well-being of patients post-therapy, the sham Reiki placebo was also statistically significant.
- A 2016 pilot study involving breast cancer survivors undergoing chemotherapy found that both Reiki and companionship groups reported improvements in quality of life and mood greater than those seen in the usual care group.
- A 2016 pilot study found that a group receiving distant Reiki sessions demonstrated reduced levels of pain, stress and fatigue compared to those receiving typical care.

In his book Naturopathic Oncology, Neil McKinney, ND, lists Reiki as one of the leading remedies he uses in his integrative cancer care plans. He prefers the traditional Usai method. He notices that his patients receiving Reiki make dramatic physical and emotional shifts. He says that it is particularly helpful in reducing radiation and/or chemotherapy-induced fatigue. He emphasizes that Reiki is compatible with all other healing modalities—conventional and alternative—and is not a religious practice.
