When you cough, there is a cough point, which is an acupuncture point on top of the Ren Vessel. The Ren Vessel follows a line in the middle of the front of the body, and this acupuncture point is at the bottom of the neck, the pharynx and the side of the sternum, and there is a nest from the sternum upwards. If you don’t have a San Fu patch, you can also rub your palms together and put your palms against the acupuncture point, you will feel that your throat and airway are very comfortable, so it is particularly effective in relieving airway sensitivity, so it is also the most commonly used cough point.
