There have been times in my life when I've wished I knew of this point and how powerful it can be. It is the one point everyone should know.
Michael Reed Gash (http://acupressure.com/) tells you about this point in the video at the bottom of this post. He's got a lovely way of describing how to use this point to help you. According to Michael, you must "firmly press GV 26 between your upper lip and nose, on the center midline. It is one third the distance from the nose to the upper lip. It has considerable influence on the central nervous system. Press this Center of the Perons (GV 26) point firmly enough to press into your upper gum, which can enable you to concentrate, feel more centered and focused."
It is also a revival point as it calms and restores the spirit after a traumatic experience. Pressing GV 26 is a potent point for mental health because it relieves depression, revives consciousness, and improves morale.
"A Spiritual Teaching: This acupressure point clears your mind, enabling you to think more positively. When you treat yourself more positively, it makes a huge difference. In addition to using this point, train yourself to think in a positive way. What you focus on, you attract in your life. . ."
When doing this point, use your nail or tip of the index or middle finger to apply mild pressure in a vertical direction for approximately 1 minute. Breathe freely and visualize a clear mind with sharp mental functioning. If you have high blood pressure, take care not to stimulate this point too hard and if you feel unwell or uncomfortable, stop immediately. But for most people, performing this acupressure workout will help invigorate mental alertness and brain function. It will also help center and calm your spirit after a traumatic event.
Check out his video below. It's only 3 minutes and Michael explains it well. You can do this point anywhere and not look strange.
