This ancient and often very effective healing method was first used in China more than 5,000 years ago. The name "acupressure" derives from the Latin "acus," or point, and "pressus," or pressure. The acupressure technique involves applying pressure to or massaging specific trigger points on the skin, which is thought to have a therapeutic effect on the entire body. It is based on two traditional tenets of Chinese medicine: that energy forces flow through invisible channels in the body called meridians, and that illness arises from blockages of or imbalances in this energy flow. Acupressure is thought to restore the flow of energy, thereby curing disease and promoting health. Its practitioners believe that performed regularly, it can help prevent illness and alleviate pain and other symptoms of disease.
