It is an ancient form of massage techniques followed by Traditional Chinese medicine. With the help of fingertips, an area is pressurized and massaged helping with issues such as Insomnia, Stress management, Headache, Menstrual cramps, Motion sickness, Muscle tension and pain, Nausea and vomiting during pregnancy and morning sickness, Nausea and vomiting after surgery or chemotherapy, and Cancer-related and other forms of fatigue. Specific energy pathways are targeted to encourage free flow energy in the body and unblock the blocked pathways which is said to provide relief. Acupressure is an alternative medicine technique often used in conjunction with acupuncture or reflexology. It is based on the concept of life energy, which flows through "meridians" in the body. In treatment, physical pressure is applied to acupuncture points, or ashi trigger points, with the aim of clearing blockages in these meridians. Pressure may be applied by hand, by elbow, or with various devices. Although some medical studies have suggested that acupressure may be effective at helping manage nausea and vomiting, insomnia, low back pain, migraines, and constipation, among other things, such studies have been found to have a high likelihood of bias. There is no reliable evidence for the effectiveness of acupressure.
