The correct way to tap the pericardium meridian is along the medial midline of the arm, from the armpit to the palm of the hand, gently tapping with an empty fist in the hand for 10 to 20 minutes. The Pericardium meridian is located in the medial midline of the arm and includes points such as Tianchi, Quzhe, Qiemen, Maijie, Neiguan, Daling and Laogong. When patting the pericardium meridian, you can hold an empty fist along the medial arm center line, gently patting from the armpit to the palm of the hand, and pausing to pat a few more times when passing through key points; Or use the fingers, palm root pressing and kneading, alternating bilaterally. Strength should be moderate, in order to slightly feel the degree of heat, each patting about 10 to 20 minutes. Tapping on the pericardium meridian helps to relax the tendons and activate the channels (stretching the tendons and bones, dredging the meridians), improve blood circulation, calm the heart and tranquilize the mind, and relieve symptoms such as chest tightness and shortness of breath. If you have a broken arm, skin infection or breakage, you should not tap on the Pericardium Meridian. If you have any of the above symptoms, you should go to the hospital as soon as possible and receive standardized treatment under the guidance of a professional doctor, so as to avoid delaying your condition.
