Commentary for Feishu BL-13

As the Back Transporting point for the Lungs, Feishu BL-13 is a very important point for Lung patterns of various Exterior and Interior origins. 

First of all, this point promotes the diffusing and descending of Lung Qi. This regulates and strengthens the Nutritive and Defensive Qi in the space between the skin and muscles, so as to prevents Exterior Pernicious Factors invasion such as Wind-Cold or Wind-Heat. Typical manifestations include cough, wheezing, breathlessness, chest fullness, persistent cough in children, chest pain (from Lung patterns) and expectoration of phlegm. In this case, it is often used together with Shenzhu DU-12. Tonifying Needling method or moxa should be applied here to tonify Qi. 

It is also widely used to expels the Wind-Cold or Wind-Heat at the beginning stage of the their attack, characterized by common cold symptoms such as aversion to cold, fever, cough and sneezing. 

Furthermore, Feishu BL-13 clears Interior Lung Heat, especially if the Heat is at the Qi level of the Four Levels Theory. This situation often occurs in the acute bronchitis due to Wind invasion. Typical symptoms include high fever, thirst, coughing with profuse sticky yellow sputum, breathlessness, restlessness, a rapid pulse and a red tongue body with a thick yellow dry coating.

For above two Excess patterns, Reducing Needling method should be applied. 

Finally, when combined with Gaohuangshu Bl-43, Feishu BL-13 nourishes Lung Yin so that it calms the Mind and eliminates any suicide ideas. It is because the Lungs house the Corporeal Soul (Po), which is a physical soul with a centripetal movement, constantly materializing and constantly separating into different constituent.  It has a relationship with 'Ghost' or 'Spirits of the death'. Both Feishu BL-13 and Pohu BL-42 (both are at the same level of the back) are indicated for suicidal thoughts.
