Scientific Studies on Energy Healing

More and more people are recognizing the power of energy healing. The scientific world is starting to conduct more research into alternative healing modalities including energy healing. Increasingly more hospitals are enlisting the help of reiki practitioners in operating rooms.

All of which are very good news for mankind as a whole, methinks!

I’ve collected some research papers that support the effectiveness of energy healing. This list will grow as more research of this type is conducted, and as I find more time to add to the list.

Reiki: A Complementary Therapy for Life

“Tom was diagnosed with a very aggressive cancer and received only palliative radiation and medication. At the time of diagnosis, his symptoms suggested that he had a very limited life expectancy. With the Reiki and his intent, he was able to achieve his goal of long-term stability with freedom from immobilizing pain and swelling. Tom’s comfort and quality of life improved dramatically, and he is living well with his cancer. Reiki has been associated with dramatic results for many patients. The importance of the patient’s intent during Reiki treatments cannot be overemphasized. Some general trends seen with Reiki include: periods of stabilization in which there is time to enjoy the last days of one’s life; a peaceful and calm passing if death is imminent; and relief from pain, anxiety, dyspnea and edema. Reiki is a valuable complement in supporting patients in their end-of-life journey, enhancing the quality of their remaining days.”
