The exact location of the lack of basin is on the lateral side of the neck, in the center of the supraclavicular fossa, 4 inches from the anterior midline.
The lack of basin is an acupoint of the foot yangming stomach meridian, and the easy way to take this point is to find the supraclavicular fossa, whose midpoint is the point. The point is located on the stomach meridian with the transverse carotid artery below it, so the point should not be stabbed deeply.
In addition, because it is located in the neck, it can treat localized diseases such as sore throat, scrofula (mainly refers to tuberculosis of the lymph nodes in the neck), etc. It can also treat lung diseases such as cough and asthma, and can be combined with Zhongfu and Yunmen points. For the treatment of sore throat, this point can be combined with Shakuzawa, Shaoshang and Quchi.
This point should be operated and treated by a doctor, not self-acupuncture.
