When you have a dry cough, you can massage the Hegu point, which is part of the Hand Yangming Large Intestine meridian, because the lung and large intestine are adjacent to each other. Gently point and rub this point with your thumb about 100 times, which is effective for patients with prolonged cough. In addition, using the end of the middle finger to point and rub the Tiantu point 200 times can purify the lung qi, resolve phlegm and stop coughing, which is effective for patients with asthma, bronchitis and sore throat. The Tiantu point is located at the center of the upper sternal fossa on the front midline of the neck. Another point is the Tanzhong point, located at the midpoint of the line between the two nipples. You can also use your thumb to rub this point to regulate qi and relieve pain, produce fluid and increase liquid, which can relieve symptoms such as shortness of breath, cough and asthma.
