Which area does the Hegu acupoint work best for pain relief?

The acupoint Hegu generally refers to the "Hegu" point. It is inaccurate to claim that "Hegu is most effective for pain relief in a specific area," as pain-relieving effects usually vary from person to person. However, it tends to be particularly effective for relieving pain in areas such as the head and eyes. Detailed analysis is as follows:

Hegu belongs to the Large Intestine Meridian of Hand-Yangming. It is located between the first and second metacarpal bones, at the midpoint on the radial side of the second metacarpal bone. This acupoint has functions including sedation, pain relief, promoting circulation of meridians, clearing heat, and resolving exterior conditions. Generally, Hegu is notably effective for sedation and pain relief, helping alleviate symptoms such as fever, headache, red and painful eyes, dysmenorrhea, amenorrhea, and ear pain. It shows relatively good analgesic effects for regions including the head, eyes, abdomen, and ears. Additionally, it can help relieve excessive sweating, thirst, jaundice, sore throat, and toothache, thus offering various health benefits.

For daily health maintenance, one should eat a light and balanced diet, maintain healthy eating habits, engage in appropriate physical exercise such as jogging or hiking, and keep a regular sleep schedule with early bedtime and wake-up times to ensure sufficient sleep.
