Which point is known for tonifying the lung channel?

LU-9, also known as Taiyuan, is recognized for its significant role in tonifying the lung channel. This point is located at the wrist, where it is easily accessible and is traditionally used to strengthen lung Qi and nourish the lung yin. Its function is pivotal in treating conditions related to lung deficiency, such as chronic cough, shortness of breath, and other respiratory conditions.

In Traditional Chinese Medicine, LU-9 is considered the source point of the lung channel, which enhances its ability to support overall lung health by promoting the distribution of Qi and moisture throughout the respiratory system. Its tonifying properties make it essential when addressing issues of dryness, weakness, or deficiency that can affect lung function.

In contrast, other points listed have different primary functions. For example, LU-10 primarily activates the throat and resolves heat, while LU-7 is known for its role in promoting the release of the exterior and directing Qi. SP-10 is associated with invigorating blood and cooling the blood, making each of these points useful in their own right but less effective than LU-9 for specifically tonifying the lung channel.
