Lung Channel
1/31
Your patient presents with fever and chills, cough, sneezing, and a stuffy nose. She also complains of occipital headache. The pulse is floating and tight. You diagnose her with an external attack of wind-cold. What point would you use to release the exterior?
LU-7 releases the exterior (both wind-heat and wind-cold). It also diffuses and descends Lung qi to stop cough. Because it's the Luo-Connecting point, it also opens the nose (the Lung channel doesn't go to the nose, but the LI channel does). LU-7 is the Gao-Wu command point for the head and nape, and it's the empirical point for headache.
