Which of the following is true about BL-17?

BL-17, also known as Geshu, is indeed associated with reversing blood stagnation in the tissues. This point is located on the bladder meridian and plays a crucial role in regulating and invigorating blood flow, making it particularly effective in addressing various conditions related to blood health, such as blood stasis. Blood stagnation can lead to issues such as pain or a lack of nourishment in tissues and organs, hence the role of BL-17 is significant in promoting circulation and ensuring that blood adequately nourishes the body.

While it is true that BL-17 is influential in overall blood health, it is not classified as a source point for qi or specifically indicated for digestive issues. Additionally, while it may have an ancillary role in respiratory health indirectly through its effect on blood circulation, it is not primarily used to treat lung infections. Instead, its primary indication lies in its ability to invigorate blood and alleviate stagnation, reinforcing this understanding of the point’s traditional applications in practice.
