"The laying on of hands 'Reiki' by a highly evolved spiritual individual is a therapy which can directly affect the plane of the electrodynamic field. By this is not meant the common psychic healing, faith healing, or massage practices, which affect the vital force only indirectly through one of the three levels (Mind, Emotion (Spirit), Body).  Laying on of hands by a spiritually evolved person who is in fact a channel for universal energies can directly strengthen the defense mechanism and thereby bring about a lasting cure."  The Science of Homeopathy by George Vithoulkas

Reiki is a vibrational healing practice that engages your bodies self healing and balance.

There have not been any known cases of Reiki interacting with medications; on the contrary, Reiki has even been known to aid with side effects from anesthesia, radiation treatment and chemotherapy.  Cancer patients claim that reiki has helped with pain management, relaxation, and side effects of treatment like nausea and stomach upset. 

Reiki is a safe, gentle, non-invasive healing technique.  It complements any medical treatment by stimulating the body's own natural healing process. Reiki has no bad side effects, it reduces stress, pain, and promotes deep relaxation. Reiki is performed by using a series of hand positions placed on or close to the body. Reiki is given while the patient is fully clothed and lying comfortably on a massage table. Since it is so adaptable, Reiki can also be given in any setting, in a chair or hospital bed.
