Energy Therapies: Overview


Also known by these names:

  • Acupuncture/electroacupuncture
  • Aura healing
  • Energy healing
  • Energy psychology
  • Healing Touch
  • Johrei
  • Magnet therapy
  • Polarity therapy
  • Pulsed electromagnetic fields
  • Quantum-touch
  • Reconnective healing
  • Reiki
  • Therapeutic Touch® (TT)

Key Points

  • Energy therapies use many techniques, all with a goal of restoring the flow of human energy fields for relieving symptoms, restoring health and/or reducing the risk of disease.
  • Our interest in these therapies lies in their usefulness in relieving symptoms, improving quality of life and potentially in life extension.
  • Several of these therapies have been recommended in clinical practice guidelines, primarily for symptom management.
  • Most energy therapies involve very little risk.
  • Benefits of energy therapies vary from individual to individual.
  • The mechanism of action of energy therapies is not understood, although many hypotheses have been advanced.
  • No strong clinical trial evidence to date shows that these therapies have antitumor effects.
  • Costs of these therapies are important to consider, as they are typically not reimbursed by insurance, although acupuncture and electroacupuncture may be reimbursed by some plans.
  • Most of these therapies are best conducted by competent practitioners. Qigong may be practiced alone, but instruction from a competent practitioner is helpful.
  • People can be trained to administer electroacupuncture at home.
  • These therapies are most likely beneficial across a wide range of cancers, even though research to date may focus on only a few cancer types.

Biofield energy therapies, also known as subtle energy therapies, rely for their efficacy on energies in and around the human body that we don't understand. For some readers, this may sound like hokum. For others, the reality of these energies is beyond question.

The National Cancer Institute defines energy therapy:1

A form of complementary and alternative medicine based on the belief that a vital energy flows through the human body. The goal of energy therapy is to balance the energy flow in the patient. It is used to reduce stress and anxiety and promote well-being. Energy therapy is being studied in patients receiving cancer therapy, to find out if it can improve quality of life, boost the immune system, or reduce side effects. Also called energy healing.

According to the NCI’s Office of Cancer Complementary and Alternative Medicine, (OCCAM):2

Energy therapies involve the use of energy fields. There are two types:

  1. Biofield therapies are intended to affect energy fields that purportedly surround and penetrate the human body. The existence of such fields has not yet been scientifically proven. Examples:
    1. Qigong
    2. Reiki
    3. Therapeutic Touch®
  2. Electromagnetic-based therapies involve the unconventional use of electromagnetic fields, such as pulsed fields, magnetic fields, or alternating-current or direct-current fields. Examples:
    1. Pulsed electromagnetic fields
    2. Magnet therapy

Acupuncture and Electroacupuncture

Though acupuncture and electroacupuncture are often classified under the CAM (complementary and alternative medicine) categories of Alternative Medical Systems or Traditional Medical Systems, these therapies involve the balancing and manipulation of energy channels, and as such could be considered energy therapies as well. The evidence base for and uses of acupuncture/electroacupuncture are more developed than for other energy therapies. We provide information in a separate summary about acupuncture and electroacupuncture.

Overview of Biofield Therapies

Biofield energy therapies include several techniques, with most energy medicine practitioners aiming to restore the flow of energy fields of the human body to relieve symptoms, restore health and reduce the risk of disease. We do not yet have a good understanding of how these therapies exert their effects.

Most energy medicine practitioners aim to restore the flow of energy fields of the human body to relieve symptoms, restore health and reduce the risk of disease.

Distinctions between Healing Touch, Therapeutic Touch® and Reiki

A review article by Pamela Potter provides a table summarizing the distinctions between Therapeutic Touch®, Healing Touch and Reiki. It includes a description of each practice’s approach to teaching, course levels, mentoring, intentionality, technique, anecdotal benefit, efficacy and safety.

View the table in Potter's article, Energy therapies in advanced practice oncology: an evidence-informed practice approach.3

Two of the energy therapy techniques, Therapeutic Touch® and Healing Touch, have a background in nursing. Certification is available to practitioners who meet specific educational and practice criteria. Other biofield therapy practitioners may be unlicensed and/or unregulated.7 Qigong and Reiki practitioners are also trained, but in the style of Master (Sensei) training that is common in Asian martial arts lineages.

Energy Fields and Religion

Some healing practices associated with certain religious traditions—such as laying on of hands—are not included in this summary but can be found in the BCCT summary on Religious and Spiritual Approaches. Energy therapies on this page do not come from a religious source; they are useful within all religious traditions.8

Evidence of Therapeutic Effects

Qigong or Tai Chi: What’s the Difference?

The follow summary draws from Tai Chi Society9 , the Qigong Institute10 and

The qi (also spelled chi) is “the life energy that flows through the body’s energy pathways.” Tai chi and qigong both cultivate the qi by combining movement, breathing and meditation. Tai chi is the most well-known and popular moving form of qigong. The practitioner uses visualization, breathing and body movement to guide the circulation of qi as it moves through and around the body. Other characteristics in common:

  • The same fundamental principle (relaxation)
  • The same fundamental method (slowness)

Studying the effectiveness of these therapies is difficult because of the challenges in creating controls and placebo conditions. Funding research is also difficult.

Research findings to date have been mixed, and many studies have methodological weaknesses, prompting experts reviewing the evidence to conclude that the research is still sparse, needing larger trials with stronger research methods.12

Clinical Practice Guidelines

2009 evidence-based clinical practice guidelines for integrative oncology say that “Therapies based on a philosophy of bioenergy fields are safe and may provide some benefit for reducing stress and enhancing quality of life. There is limited evidence as to their efficacy for symptom management, including reducing pain and fatigue.” The guidelines give a strong recommendation for these therapies:13

Biofield therapies are thought to be safe, although evidence of effectiveness and mechanisms of effect is limited.15

Specific Biofield Therapies

Descriptions, research, cautions and information about finding practitioners for individual biofield therapies are summarized in separate pages:

  • Acupuncture and Acupressure: therapies involving stimulation of one or more designated points on the body with needles (acupuncture), pressure (acupressure), or electricity (electroacupuncture, EA).
  • Healing Touch: a heart-centered energy therapy that uses gentle, intentional touch that assists in balancing physical, emotional, mental, and spiritual well-being.
  • Johrei: a biofield energy healing technique involving a non-touch transfer of life energy.
  • Polarity Therapy: a therapy in which energy is conducted through hands-on touch with the goal of removing energy blocks and restoring smooth, free flow of energy.
  • Qigong: an ancient Chinese practice consisting of a combination of movement, self-massage, meditation, and breathing.
  • Reiki: a Japanese technique for stress reduction and relaxation that also promotes healing.
  • Tai Chi: the most well-known and popular moving form of qigong. The tai chi practitioner uses visualization, breathing and body movement to guide the circulation of qi as it moves through and around the body.
  • Therapeutic Touch®: a holistic, evidence-based therapy that incorporates the intentional and compassionate use of universal energy to promote balance and well-being

Electromagnetically Based Therapies

A description and summary of evidence regarding electromagnetically based therapies is available on our Bioelectromagnetically Based Therapies page.

Written by Laura Pole, RN, MSN, OCNS, and Nancy Hepp, MS; most recent update on June 19, 2019. BCCT has not conducted an independent review of energy therapies research. This summary draws from several sources, including About Herbs, CAM-CancerNational Center for Complementary and Integrative Health (NCCIH) and other sources as noted.
