Which jin-river points are known for their effectiveness in treating cough and dyspnea?

Jin-river points are a category of acupuncture points located on the yin channels and are traditionally understood to be particularly effective for treating issues related to the lungs, including cough and dyspnea. The designation of these points as "Metal points" specifically ties into the Five Elements theory, where Metal is associated with the lungs.

The Metal element is linked to both the lungs and the act of respiration, which makes these points useful for addressing respiratory conditions. Metal points are believed to have the properties of dispersing and descending Qi, which can alleviate symptoms such as cough and difficulty breathing. Selecting Metal points to focus on lung-related issues is a practice grounded in the elemental theory of TCM where each element corresponds to specific organs and their functions.

Thus, understanding that jin-river points classified as Metal are particularly effective for treating respiratory symptoms, the choice that they represent Metal points directly connects to their therapeutic role in managing cough and dyspnea.
