Final answer:
Nei Guan is an acupuncture point, known as P6 or Pericardium 6, used primarily to alleviate nausea and is located on the wrist. It is beneficial for nausea caused by various factors including chemotherapy, surgery, and pregnancy and can be stimulated through acupuncture, acupressure, or manual pressure.
Step-by-step explanation:
Nei Guan is not a medication, dietary supplement, or a relaxation technique but rather an acupuncture point widely recognized in traditional Chinese medicine. It is specifically located on the wrist and is commonly used for the treatment of nausea and vomiting. The proper term is P6 or Pericardium 6, and it lies approximately three finger breadths below the wrist on the inner forearm in between the two tendons.
Studies have shown that stimulating the Nei Guan point can be an effective method to reduce the symptoms of nausea, especially related to chemotherapy, surgery, and pregnancy. It is also used for other purposes such as addressing headaches, anxiety, and motion sickness. The stimulation can be done through acupuncture, acupressure wristbands, or gentle manual pressure.
