What’s the difference between Sanyinjiao and Taichong?
Sanyinjiao and Taichong are the two acupoints that beginners most often confuse. Both are known to support women’s health, be effective for insomnia, and help relieve stress. However, these two acupoints operate in significantly different regions of the body, have different directions of energy flow, and have distinctly different primary benefits. If Sanyinjiao is the ‘strong foundation’ responsible for the digestive, reproductive, and immune systems of the lower body, then Taichong is the ‘gateway of emotion’ that oversees qi and blood circulation throughout the body and emotional stability. This is why the acupoint you choose should vary depending on your specific symptoms.
Understanding Sanyinjiao (SP6) in depth
Exact location
Sanyinjiao is an acupoint located on the inner side of the ankle. Its exact location is four finger-widths (approximately 3 cun) directly above the protruding bone on the inner ankle (medial malleolus), on the inner surface of the tibia (shinbone). Sit down and place one foot on the opposite leg, then move your fingers upward from the protruding bone on the inner ankle, and you’ll feel a slightly recessed area. This is Sanyinjiao. It exists on both the left and right legs, and stimulating both sides is more effective.

Sanyinjiao is the most powerful acupoint for women-specific symptoms. If you suffer from severe menstrual cramps or have irregular menstrual cycles, Sanyinjiao is highly recommended. In particular, pressing it daily for 5-7 days before your expected period can significantly reduce the intensity of menstrual pain. Additionally, those suffering from chronic insomnia, frequent nighttime awakenings, and sudden fatigue can experience significant relief. Since Sanyinjiao connects to the spleen-pancreas meridian and activates digestive function, it’s also effective for indigestion and abdominal bloating. Those who struggle with edema that won’t go away, especially those experiencing heaviness in the legs due to lower body swelling, also experience significant improvement through Sanyinjiao pressure therapy.
Massage technique and tips
Since Sanyinjiao is located relatively deep, you should apply strong pressure using the padded part of your thumb (the fleshy area, not the nail). Apply pressure slowly for about 3-5 seconds, then release, and repeat. Continue for a total of 3-5 minutes, maintaining moderate pressure that causes some discomfort. As the saying goes, ‘pain means it’s working,’ so feeling some discomfort is normal. When pressing, maintain comfortable breathing and never hold your breath. Pressing in the evening (around 5-7 PM) improves sleep quality at night. When experiencing menstrual pain, you can apply stronger pressure and stimulate it longer. The effect is doubled if you apply warm compresses before the massage.
Understanding Taichong (LR3) in depth
Exact location
Taichong is an acupoint located on the upper part of the foot. Its exact location is at the point where the first metatarsal (big toe bone) and second metatarsal (index toe bone) meet – a slightly indented area in the center of the top of the foot. Looking down at the top of your foot, find the point 2-3 centimeters up from the webbing between your big toe and index toe. Since this acupoint is close to the top of the foot, it’s easier to locate than Sanyinjiao. It’s located on both feet, and depending on your symptoms, you can stimulate just one side or both.
Recommended for those with:
Taichong is an acupoint that addresses ’emotional issues.’ It’s very effective for stress-related headaches, particularly throbbing pain on both sides of the temples. Those who experience rising anger and difficulty controlling feelings of rage due to work stress or interpersonal conflict can calm their emotions through Taichong massage. Those who frequently experience dizziness or vertigo, or those with elevated blood pressure, can also see improvement through Taichong stimulation. Additionally, Taichong is an excellent choice for those suffering from emotional instability such as anxiety, restlessness, and sensitive mood changes. Chronic stress-related neck and shoulder tension can also be relieved through Taichong pressure therapy.
Massage technique and tips
Taichong is located more shallowly than Sanyinjiao, so apply moderate pressure. Use your thumb to press with ‘the feeling of pressing a coin’ for 3-4 seconds, then release and repeat. Continuing for 2-3 minutes at a time is sufficient, and the appropriate pressure level is when you feel a ‘refreshing sensation’ or ‘warmth’ rather than pain. Pressing immediately when stressed or angry helps emotional stabilization. Pressing in the morning when you wake up or around 3 PM (when the liver meridian is most active) is even more effective. The effect of Taichong massage is amplified when combined with meditation or deep breathing. It’s best to avoid pressing when extremely fatigued, and press at least one hour after meals rather than on an empty stomach.

| Location difficulty | Moderate (inner ankle, deep) | Easy (top of foot, shallow) |
| Pressure intensity | Strong pressure (slightly painful) | Moderate pressure (refreshing sensation) |
| Recommended time | Evening 5-7 PM (improves sleep) | Morning or around 3 PM (emotional stability) |
| Meridian system | Spleen-Pancreas (digestion, women’s health) | Liver (emotions, blood circulation) |
| Beginner suitability | ★★★☆☆ (hard to locate) | ★★★★★ (easy to locate) |
Synergistic effects when stimulated together
Since Sanyinjiao and Taichong are responsible for different areas, stimulating them together creates a synergistic effect. In particular, if you’re a woman with severe stress or experiencing emotional instability due to premenstrual syndrome, it’s good to stimulate both acupoints. The recommended method is to first stimulate Taichong (top of foot) for 2-3 minutes to calm your mind, then stimulate Sanyinjiao (inner ankle) for 3-5 minutes. This way, emotional stability and physical recovery occur simultaneously, maximizing overall well-being benefits. Especially during the 5-7 days before your period, continuously stimulating both acupoints in the evening can significantly reduce menstrual pain as well as reduce pre-menstrual anxiety and depression. However, when fatigue is severe, focus on shallow stimulation (Taichong) rather than deep stimulation (Sanyinjiao), and avoid excessive stimulation.
Conclusion: Selection guide by situation
Choose Sanyinjiao: When you have severe menstrual cramps, insomnia, or extreme fatigue. In particular, as a woman, regularly stimulating Sanyinjiao as part of health management can provide long-term physical health improvements.
Choose Taichong: When you have stress-related headaches, tend to get angry frequently, or experience severe anxiety. In work-related stress situations, Taichong massage provides immediate emotional calming effects.
Choose both together: When you experience both emotional changes and physical symptoms due to PMS (premenstrual syndrome), or when you have menstrual irregularities caused by stress. When mind and body problems are intertwined, harmonious stimulation of both acupoints creates the best results.
