Reiki has a positive affect on all forms of illness and negative conditions. The body-mind is a psychophysical unit and as such, anything that benefits the mind, benefits the body, and vice versa. This healing benefits of Reiki positively influence minor afflictions like head or stomach aches, bee stings, colds, flu, tension and anxiety as well as serious illnesses such as heart disease, cancer, digestive disorders (Morbus Crohn, Coeliac Disease), etc. The side effects of regular medical treatments have also been reduced or eliminated. This includes the negative effects of chemotherapy, post-operative pain and depression as well as improving the healing rate and reducing the time needed to stay in the hospital. Reiki always helps and in some cases people have experienced complete healings which have been confirmed by medical tests before and after the Reiki treatments. Of course, while some have experienced "miracles", these cannot be guaranteed. Stress reduction with some improvement in one's physical and psychological condition are what most experience.
