Which acupuncture point is often used in the treatment of headaches?

The acupuncture point that is commonly used in the treatment of headaches is LI-4, also known as Hegu. This point is located on the dorsum of the hand, between the first and second metacarpal bones. LI-4 is recognized for its ability to release exterior conditions and is particularly effective for alleviating pain, including headaches.

This point functions by promoting the smooth flow of Qi and blood throughout the body, which can address underlying imbalances that contribute to headaches. In Traditional Chinese Medicine (TCM), headaches are often associated with Qi stagnation or a deficiency of blood or yin, and LI-4 helps in harmonizing these elements. Its systematic action on the head and face makes it a go-to point for various types of headaches, including tension-type headaches and migraines.

While the other points listed have their own indications and can be used in the broader context of treatments for various conditions, LI-4 is specifically renowned for its effectiveness in treating headache conditions, making it the preferred choice in this context.
