What’s the Difference Between Lieque (LU7) and Zhaohai (KI6)?
There are two acupressure points located on the hands and feet that handle completely different areas of the body. These are Lieque (LU7) and Zhaohai (KI6). Many people confuse these two points because they share similar Chinese character names and overlapping symptoms (especially sore throat). However, the two points work through different meridians, and their effects operate at different depths. Lieque is a point on the wrist that governs lung qi and responds quickly to acute respiratory symptoms, while Zhaohai is a point on the ankle that nourishes kidney yin and slowly addresses chronic nervous system issues. In this article, I’ll compare these two points in depth to help you choose the right one for your symptoms.
Understanding Lieque (LU7) in Depth
Exact Location
Lieque is located approximately 1.5 cun (about 4-5 cm) above the inner wrist crease, in the direction of the elbow. More precisely, you can find it in the small depression (indentation) just above the radial styloid process (the bony prominence on the thumb side of the forearm). When you bend your wrist, a thick tendon becomes visible on the thumb side. Following the space between this tendon and the bone upward, you’ll find Lieque. Check if there’s tenderness. If you’ve found the correct point, pressing it will produce a sharp, tingling pain or a cool sensation that radiates through the entire arm.
Who Should Use It
Lieque is the terminal point (jing point) of the lung meridian—the place where lung qi is released to the outside. Therefore, it shows immediate effects when you have chills and a slight fever in the early stages of a cold, or when a cough has already started. When you have a persistent dry cough or a swollen throat making it difficult to swallow, few acupressure points are as effective as Lieque in quickly relieving symptoms. It also helps when migraines or tension headaches cause facial flushing. If you frequently catch colds during seasonal transitions or tend to develop sore throats and pharyngitis, it’s good to regularly monitor the condition of Lieque.
Acupressure Technique and Tips
When applying pressure to Lieque, it’s most effective to press slowly using the joint area of your thumb rather than the nail. Begin with gentle pressure of about 2-3 kg for 30 seconds to 1 minute. When you have early cold symptoms, apply acupressure 3-4 times daily, about 1 minute each time. For cough or sore throat, maintaining moderate pressure consistently is better than applying strong pressure. After applying acupressure, drink warm water or ginger tea to enhance the effect. Interestingly, stimulating Lieque often causes the skin to turn red, which is a sign of improved blood circulation. Keeping the throat warm with a scarf or towel right after acupressure makes the effect even better.
Understanding Zhaohai (KI6) in Depth
Exact Location
Zhaohai is located approximately 1 cun (about 2.5-3 cm) below the lowest point of the medial malleolus (inner ankle bone), in a small depression. When your foot is relaxed, feel below the medial malleolus with your fingers to find a spot that feels slightly tender or cool. Zhaohai is a bit trickier to locate than Lieque. If your ankle is swollen or you have eczema, identifying the location can be difficult. Once you find it on one foot, you can stimulate the same location symmetrically on the other foot, so it’s recommended to stimulate both sides.
Who Should Use It
Zhaohai is a key point of the kidney meridian that nourishes kidney yin and stabilizes the nervous system. Therefore, it’s excellent for insomnia where you toss and turn unable to sleep, or frequently wake in the early morning hours—especially sleep disorders caused by anxiety. If you become extremely anxious before your menstrual cycle or suffer from severe menstrual cramps due to abdominal tension, regularly stimulating Zhaohai improves hormonal balance. People struggling with constipation can also experience significant effects from Zhaohai, especially for stress-related constipation or irritable bowel syndrome. Like Lieque, Zhaohai also addresses sore throat, but while Lieque handles acute sore throat, Zhaohai addresses the chronic symptom of a dry and sore throat. It also improves the heat sensation (flushing) and night sweats that menopausal women experience.
Acupressure Technique and Tips
To stimulate Zhaohai, it’s effective to lie down, bend one leg, place your other foot on top of your knee, and slowly press with your thumb or a rounded acupressure tool. Initially, apply gentle pressure (about 2 kg) for 10-15 seconds, repeated several times. Once you adapt, maintain moderate pressure for 30 seconds to 1 minute. If you have insomnia, stimulate Zhaohai 30 minutes before bedtime, and your nerves will calm down for natural sleep. After stimulating Zhaohai, drinking warm milk or warm jujube tea enhances the sleep-inducing effect. An important point is that Zhaohai takes longer to show results than Lieque. You need to apply acupressure consistently for at least a week or more to feel the effects, so approach it with patience. Starting 7-10 days before your expected menstrual period and stimulating Zhaohai daily provides the best effect for menstrual pain relief.
Key Comparison Summary
| Item | Lieque (LU7) | Zhaohai (KI6) |
|---|---|---|
| Primary Effects | Colds, cough, sore throat, headache (acute) | Insomnia, anxiety, menstrual cramps, constipation (chronic) |
| Location | 1.5 cun above wrist crease, above radial styloid process | 1 cun below inner ankle bone |
| Meridian | Lung meridian (Tai Yin of Hand) | Kidney meridian (Shao Yin of Foot) |
| Difficulty Finding Location | Easy | Moderate |
| Speed of Effect | Fast (same day to 2 days) | Slow (1 week or more) |
| Pressure Intensity | Moderate to strong | Gentle to moderate |
| Common Symptom | Sore throat (however, Lieque handles acute cases, Zhaohai handles chronic cases) | |
| Season | Primarily autumn and winter | Year-round needed |
They Create Synergy When Stimulated Together
Interestingly, stimulating Lieque and Zhaohai together creates greater synergy than stimulating either one alone. For example, you might have a cold while simultaneously experiencing anxiety and sleep deprivation. In such situations, quickly calming the lung’s cough symptoms with Lieque and stabilizing the nervous system with Zhaohai significantly speeds up overall body recovery. Additionally, when your immunity drops due to seasonal changes, regularly stimulating Zhaohai beforehand to replenish kidney qi means that if you do catch a cold, stimulating Lieque alone will bring faster recovery. In actual clinical practice, patients with both insomnia and chronic cough are often recommended to use both points. By stimulating Zhaohai 30 minutes before bed and Lieque during the day when coughing is severe, you can dramatically improve your overall physical condition with minimal effort.
Conclusion: Situation-Based Selection Guide
For early cold symptoms or severe cough → Lieque
Choose Lieque if you want results today or tomorrow. Especially in the early stages of throat cold, few acupressure points are as effective as Lieque. Acupressure 3-4 times daily is sufficient.
For chronic insomnia and deep anxiety → Zhaohai
If you want long-term improvement, consistently stimulate Zhaohai. You’ll need to apply acupressure regularly for at least 2 weeks, ideally about a month, to truly feel the effects.
For anxiety and pain occurring before your menstrual cycle → Zhaohai first
Starting 7-10 days before your expected period, stimulate Zhaohai daily. If menstrual cramps begin, you can additionally stimulate Lieque as needed.
For chronically dry and sore throat → Zhaohai
Since this is a chronic symptom, nourishing kidney yin with Zhaohai is the fundamental solution.
For simultaneous cold and anxiety → Stimulate both
Use Lieque for lung symptoms and Zhaohai to stabilize the nervous system for faster recovery.
Ultimately, Lieque and Zhaohai are like an emergency room and psychiatry department. Lieque responds quickly to urgent symptoms, while Zhaohai slowly heals deep nervous system problems. Choose the right acupressure point for your situation, and use both together when necessary to restore complete health.
