For cough with phlegm, which acupoint is generally recommended?

The recommended acupoint for cough with phlegm is LU-5, which is located on the radial side of the biceps tendon in the cubital crease. This point is known as "Chi Ze," which translates to "Pool of Blood." LU-5 is particularly effective in treating respiratory issues because it is a lung channel point that helps to clear phlegm and alleviate cough. It has the distinct property of being a water point on the lung meridian, which correlates with its ability to transform and expel phlegm from the lungs.

Using LU-5 in treatment focuses on its action to regulate lung qi and promote the secretion of fluids, thereby helping to clear excess phlegm and soothe the cough. In traditional Chinese medicine, cough with phlegm often indicates an underlying issue with phlegm accumulation, and LU-5 directly supports lung function and enhances the body’s ability to resolve this excess.

While the other points listed—such as Ren-12, ST-36, and LI-4—have their own therapeutic benefits, they are not as specifically indicated for cough with phlegm as LU-5 is. Ren-12 is more associated with stomach and digestive issues, ST-36 helps strengthen
