The below uses are based on tradition or scientific theories. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious and should be evaluated by a qualified health care professional.
Uses based on scientific evidence
These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare professional.
Autonomic nervous system disturbances
One randomized trial suggested that Reiki may have an effect on autonomic nervous system functions such as heart rate, blood pressure, or breathing activity. Large, well-designed studies are needed before conclusions can be drawn.
Reiki may contribute to reduced perception of pain, improved quality of life, and reduced fatigue in cancer patients. More studies are needed.
Cognitive disorders (mild cognitive impairment)
Early research suggests that Reiki therapy may improve behavioral and memory problems in patients with mild cognitive impairment or mild Alzheimer's disease. However, additional studies are needed to confirm these findings.
Depression and stress
There is evidence that Reiki can reduce symptoms of distress when compared to placebo. More information is needed before a conclusion can be drawn.
Reiki instruction may help HIV/AIDS patients reduce pain or anxiety, but results are unclear.
Patients in a preliminary ("phase II") trial of Reiki in combination with standard pain medications (with opioids) were reported to experience improved pain control. Further research is needed to confirm these findings.
In a randomized controlled trial, Reiki did not have any clinically useful effect on stroke recovery in patients receiving appropriate rehabilitation therapy. Selective positive effects on mood and energy were noted.

Many complementary techniques are practiced by healthcare professionals with formal training, in accordance with the standards of national organizations. However, this is not universally the case, and adverse effects are possible. Due to limited research, in some cases only limited safety information is available.
Natural Standard developed the above evidence-based information based on a systematic review of the available scientific articles.
