Overview of the efficacy and function of Lingxu Point

Lingxu point is an important acupoint on the Kidney meridian of Foot Shaoyin, located in the third intercostal space of the chest, 2 inches from the front midline. Its main functions include regulating cardiopulmonary function, relieving chest tightness and shortness of breath, improving breast problems and assisting in the treatment of insomnia. In the theory of traditional Chinese medicine, Lingxu point has a positive effect on the respiratory system, circulatory system and emotional regulation by dredging the kidney meridian qi and blood. In clinical application, it is often combined with other acupoints to enhance the therapeutic effect, such as Tanzhong acupoint, Neiguan acupoint, etc. The following content will explain the acupoint location, specific effects, applicable symptoms and precautions.

1. The positioning of Lingxu point and the theoretical basis of traditional Chinese medicine

The name of Lingxu point comes from the "Acupuncture Jiayi Jing". "Ling" refers to gods and "Xu" means mound, which means that this point can regulate the mind. The anatomical location is in the pectoralis major muscle, the deep layer is the intercostal muscles, and the intercostal nerves and internal thoracic arteriovenous branches are distributed. Traditional Chinese medicine believes that it belongs to the kidney meridian, and the kidney is responsible for receiving qi. Therefore, stimulating this point can improve cough and asthma caused by the kidney's inability to receive qi. Modern research shows that acupuncture at Lingxu point can regulate autonomic nervous system function and relieve heart palpitations caused by sympathetic nervous hyperactivity. Acupressure or acupuncture is often used during the operation. Pregnant women and those with chest infections should use it with caution.
