Which point is used to treat hernia?

The point used to treat hernia is LR-1, also known as Da Dun. This point is located on the liver meridian and is known for its ability to regulate liver qi, which is essential in addressing conditions like hernia. In Traditional Chinese Medicine (TCM), hernias are often associated with patterns of disharmony in the liver and spleen, particularly involving qi stagnation or deficiency. LR-1 helps to move and harmonize liver energy, thus potentially alleviating the symptoms or conditions related to hernias.

While other acupoints may have different uses and effects on the body, they are not specifically indicated for treating hernia. SP-1 is more often associated with spleen issues and blood regulation, BL-67 is primarily utilized for conditions related to the bladder and reproductive organs, and SP-21 is typically associated with pain relief and regulation of the body's energy balance. Therefore, LR-1 is the correct choice for addressing the specific condition of a hernia in the context of TCM practice.
