Taichong (LR3) vs Union Valley (LI4) — Which Acupressure Point Should You Use?

Taichong and Hegu, What’s the Difference?

When experiencing headaches or dizziness caused by stress, many people are confused about whether to press Taichong or Hegu. Both acupoints are effective for stress relief and headache improvement, but the mechanisms by which they work are completely different. Taichong is an acupoint that regulates the liver’s energy and focuses on emotional stability and stress relief, while Hegu is a key point on the large intestine meridian that rapidly promotes the circulation of qi and blood throughout the entire body.

Diving Deep into Taichong (LR3)

Exact Location

Taichong is located on the top of the foot. It is situated approximately 1cm up toward the center of the foot from the valley between the big toe and the second toe, at the depression just in front of the junction of the first and second metatarsal bones. The method to find it is simple: follow the area between the two toes upward, and at the point where the bones meet, about 1cm away, you’ll find Taichong. It’s easier to locate if you remember that it’s positioned slightly higher toward the ankle direction rather than the very top of the foot near the toes.

Taichong is particularly effective for those with significant emotional fluctuations, those who frequently feel anger caused by stress, and those suffering from chronic headaches. In traditional medicine, the liver is called the “emotional storage center,” and when stress and anger accumulate, liver qi becomes blocked, resulting in headaches, dizziness, and eye fatigue. Additionally, those with high blood pressure, those who frequently wake at night or have insomnia, and women experiencing premenstrual syndrome (PMS) can also benefit greatly. Especially if you want to address the fundamental cause of stress-induced symptoms, Taichong is more suitable.

Acupressure Method and Tips

Acupressure on Taichong is based on gentle and consistent stimulation. Press the toes with a wooden chopstick or massage gently using the fingerprint area of your thumb. Apply moderate pressure at a level where you feel “ah, this feels refreshing,” pressing for 10 seconds and resting for 5 seconds, repeating this for about 1-2 minutes. After completing one foot, do the same on the other side. It’s particularly effective when done before bed or right after experiencing stress. If you warm your feet thoroughly with warm water before acupressure, blood circulation improves and the effect is doubled. Be careful not to apply excessive force, as overly strong pressure can tire your feet; instead, aim for consistent and gentle stimulation.

Diving Deep into Hegu (LI4)

Exact Location

Hegu is an acupoint located on the hand and is one of the easiest acupoints to find. It is located approximately 1cm up toward the back of the hand from the web (the crease between the fingers) between the thumb and index finger, above the midpoint of the second metacarpal bone (the bone of the index finger). The simplest way to find it is to bring your thumb and index finger together, and a small depression will form on the back of your hand—that’s exactly where Hegu is. Even when you spread your fingers and bring them together again, it’s at the same location, so you can easily stimulate it anywhere.

Hegu is the acupoint that shows the most widespread effect for pain relief throughout the entire body. It works quickly for toothaches, facial pain, and headaches (especially temporary pain). It’s also effective for early symptoms of colds or flu and for strengthening immunity. Those with temporomandibular joint pain or facial nerve pain caused by stress can also benefit. Hegu is more effective especially when you need acute pain relief and want immediate symptom relief in emergencies. It’s also a practical acupoint for office workers who experience fatigue and headaches in the afternoon and need immediate relief.

Acupressure Method and Tips

Hegu can tolerate stronger stimulation than Taichong. Press the Hegu area firmly with the thumb of the opposite hand, applying pressure at a level that is “painful but refreshing,” pressing for 10-15 seconds and resting for 2-3 seconds, repeating this for 1-2 minutes. Rubbing in circular motions is also effective. Being able to stimulate both hands alternately is a major advantage, as you can do it easily anytime and anywhere. If a headache develops while working on a computer, you can press it immediately, or if you have a toothache, stimulating it right away will produce quick results. Note that pregnant women should avoid acupressure on Hegu.

Key Comparison Summary

You’ll Experience Synergy When Pressing Both Together

When stimulating both Taichong and Hegu together, you can experience even more remarkable effects. When you have a headache caused by stress, first relieve the immediate pain with Hegu, then address the root cause of stress with Taichong to maximize the effect. Particularly when experiencing headaches and sensitivity from premenstrual syndrome, or when suffering from tension headaches and dizziness due to work stress, stimulating both acupoints in sequence produces excellent results. The stimulation order should be to stimulate Hegu first for 1-2 minutes, then stimulate Taichong for 2-3 minutes. If you follow this routine 3-4 times per week, you’ll experience significant relief from chronic stress and headaches.

Conclusion: Selection Guide by Situation

If you currently have a headache or need immediate pain relief, choose Hegu. You can stimulate it immediately with your hand and see results within minutes. On the other hand, if you’re suffering from chronic stress and anxiety, emotional instability, consistently stimulate Taichong. Taichong is more effective for addressing the root cause. The most ideal approach is to utilize both acupoints. If acute stress-induced headaches develop during the day, respond quickly with Hegu, and then consistently stimulate Taichong before bed in the evening to find emotional stability. By regularly stimulating these points to normalize the flow of your body’s energy, you can develop a mind and body that are resilient to stress.
