Clinical notes

As the Jing-River and Metal point of the Lung channel, Jingqu is a key point for treating acute respiratory conditions involving cough, wheezing, and chest fullness. Its ability to descend Lung Qi makes it effective for rebellious Qi patterns like asthma and vomiting. The classical emphasis on its role in regulating Qi and blood, and its location at the radial pulse, highlights its importance in addressing systemic imbalances reflected in the pulse.
