Neiguan Point (PC6): The Wrist's Universal Health Hub
When most people mention Neiguan point, their first thought is "press it for motion sickness," yet few realize that this tiny acupoint hidden between the two tendons on the wrist is actually the "universal health hub" in TCM that "connects upward to the heart, mediates to the spleen, and reaches downward to the liver." It not only relieves everyday minor ailments but can also serve as emergency first aid for heart palpitations and fainting, while helping manage insomnia, stomach pain, and emotional anxiety—the common afflictions of modern life.
I. Neiguan's "TCM Secret Code"
Neiguan point is the Luo-connecting point of the Hand Jueyin Pericardium Meridian, and simultaneously one of the Eight Confluent Points, connecting to the extraordinary vessel Yin Linking Vessel (Yin Wei Mai).
The Pericardium Meridian acts as the heart's personal bodyguard. Since the heart serves as the body's "monarch organ" and cannot directly receive pathogenic influences, all external pressures and harmful factors are first intercepted by the Pericardium Meridian. As the Pericardium's Luo-connecting point, Neiguan functions as a "meridian traffic hub," capable of both regulating Pericardium Meridian qi-blood and communicating with multiple other meridians including the San Jiao, Spleen, and Stomach meridians.
The Yin Linking Vessel connects all yin meridians throughout the body, governing internal qi-blood circulation. TCM doctrine states: "Disorders of the Yin Linking Vessel manifest as heart pain." As the key node linking to the Yin Linking Vessel, stimulating Neiguan can unblock yin-meridian qi-blood throughout the entire body, addressing discomfort such as chest pain, tightness, and stomach pain at their root.
II. 30-Second Precise Location Method
Three-Step Localization:
Step 1: Establish the "Baseline" — Wrist Palmar Distal Transverse Crease
Extend your wrist with palm facing up. One or two distinct horizontal creases will appear on the inner wrist. Identify the crease closer to the forearm (the one farther from the hand).
Step 2: Measure the Correct Distance — How to Gauge 2 Cun
In TCM, "cun" refers to proportional measurement using your own body:
- When the index, middle, ring, and little fingers are placed together, the total width equals about 3 cun
- Therefore, 2 cun equals two-thirds of this width
- Or more simply: use the width of one thumb knuckle as 1 cun, measure two thumb-knuckles' width upward from the crease
Step 3: Lock In the Target — The Depression Between Two Tendons
At the 2-cun position, feel the inner forearm—you will detect two prominently raised "tendons" (the palmaris longus tendon and the flexor carpi radialis tendon). Neiguan point lies hidden in the depression between these two tendons. Upon compression, distinct sensations of soreness, numbness, and distension are felt.
III. 5 Core Therapeutic Functions
1. Relieve Motion Sickness Nausea & Vomiting
Applicable scenarios: Motion sickness while traveling by car, ship, or airplane
Operation method: Begin pressing 30 minutes before departure. Use index finger and thumb to pinch Neiguan point, applying gentle kneading pressure for 1 minute each time, rest 10 seconds, repeat every 15 minutes throughout the journey.
Scientific basis: A 2020 study published in the Journal of Practical TCM Internal Medicine confirmed that Neiguan stimulation significantly reduces nausea associated with motion sickness.
2. Cardiac First Aid: Palpitations, Chest Tightness, Arrhythmia
Neiguan is hailed as the "number-one acupoint for heart disease." It bidirectionally regulates heart rate—slowing tachycardia while accelerating bradycardia, truly serving as the heart's "stabilizer."
3. Regulate Digestion: Stomach Pain, Distention, Nausea, Vomiting
Neiguan excels at broadening the chest and regulating qi, harmonizing the stomach and descending rebellion. It is particularly effective for nausea, vomiting, belching, and concurrent emotional regulation.
4. Calm Spirit & Promote Sleep: Insomnia, Anxiety
Through autonomic nervous system modulation, it alleviates anxiety and improves sleep quality.
5. Relieve Pain: Headaches, Migraines
When combined with other acupoints, it effectively relieves various types of headaches.
IV. Expert Recommendations: Travel Motion Sickness Relief
Dr. Zhang Wei, Chief Physician from the Acupuncture Department, Xiamen TCM Hospital (Beijing University of Chinese Medicine Dongzhimen Hospital Xiamen Branch) recommends:
Neiguan (PC6): Three finger-widths above the wrist crease, between the two tendons—apply firm pressure to relieve nausea and retching
Hegu (LI4): Highest point of the tiger's mouth—pinch and knead to improve dizziness and chest tightness
Zusanli (ST36): Four finger-widths below the knee, lateral side—press until soreness is felt to stabilize digestion and prevent motion sickness
Taichong (LR3): Between the big toe and second toe on top of foot—soothes liver and relieves dizziness
V. Driver-Specific Relaxation Acupoints
Director Liu Jia from the Acupuncture Department, Guang'anmen Hospital Xidan Outpatient Clinic (China Academy of Chinese Medical Sciences) introduces:
3 Exclusive "Relaxation Acupoints" for Drivers:

Jianjing (GB21): Releases stiff shoulders — Location: center of shoulder, midpoint between Dazhui (GV14) and the acromion — Method: press for 15-20 seconds, pinch-lift 10-15 times
Shousanli (LI10): Reduces arm heaviness — Location: 2 cun below the cubital crease, depression lateral to bone — Method: knead for 1-2 minutes
VI. Food Remedies for Motion Sickness
The "Anti-Nausea Trio":
Fresh ginger: Slice and place under nostril to inhale, or hold in mouth; alternatively tape to navel area
Orange peel: Squeeze fresh peel to burst and inhale the released limonene vapor
Vinegar: Apply a few drops to tongue tip when motion sickness strikes
VII. Important Precautions
Pressure control: Follow the standard of "sore but not painfully sharp"
Timing: Begin pressing 30 minutes before travel for optimal effect
Contraindicated populations: Pregnant women (especially early pregnancy) should exercise caution
Conclusion
Neiguan point functions like a "multi-function remote control"—pressing the right button for each bodily issue achieves remarkable therapeutic leverage with minimal effort. For holiday travel, remember this "anti-nausea gem" hidden on your wrist, and make your journey more comfortable and pleasant!
