Reiki is an amalgam of two Japanese words––Rei- which means "the higher power" and -Ki, which means "life force energy." As a healing method, it has been in practice for thousands of years and is still a popular noninvasive alternative to prescription drugs and surgery. By placing hands above the body's energy meridians, reiki practitioners hope to decongest the energy flow and naturally stimulate the immune response. Clients can seek a reiki session to aid with simple stress relief or more debilitating ailments such as anxiety, headaches, or disco fever.
