LI4 Acupuncture Point
LI4 Acupuncture Point
The Large Intestine 4 Acupuncture Point, LI4 (Hegu), meaning “Joining Valley,” is widely considered one of the most powerful and frequently used acupuncture points across various traditions. It sits on the Large Intestine channel, well-known for influencing conditions that affect the head, neck, face, and sensory organs.
Commonly selected for headaches, jaw issues, sinus congestion, and toothaches
Often referenced in classical texts for its ability to treat external wind-cold or wind-heat syndromes
Praised for its comprehensive reach, from regulating sweat to inducing labor
By targeting both local and systemic concerns, LI4 serves as a cornerstone in the acupuncturist’s toolkit for balancing the body and relieving discomfort.
Key Points
LI4’s reputation stems from its broad scope in treating pain and releasing pathogenic factors. Its classical categorization as one of the “Heavenly Star Points” underscores its importance historically and in modern practice.
Expels wind and releases the exterior (helpful for cold and heat patterns)
Regulates sweating, making it effective whether sweating is absent or excessive
Believed to induce labor when stimulated appropriately, hence traditionally contraindicated during normal pregnancy
Restores yang energy in cases of collapse or severe deficiency
In essence, many practitioners regard LI4 as an all-purpose point to tackle pain, inflammation, or Qi stagnation, especially in the upper body.
Acupoint LI4 Names and Meaning
The name “Hegu” translates to “Joining Valley,” hinting at its location in the fleshy valley between the thumb and index finger. Ancient physicians also viewed the name as symbolic of LI4’s capacity to merge and regulate Qi flow that affects the head and face.
“Joining Valley” evokes the image of channels converging to harmonize the body’s defensive Qi
Historically referenced for unifying internal and external dynamics to bolster immune function
Such symbolism reflects LI4’s central role in clearing stagnation from the upper body and allowing energy to flow unimpeded.
LI4 Point Categories
As a Yuan-Source Point, LI4 is pivotal for regulating Qi within the Large Intestine channel. It also ranks among the “Four Command Points,” associated specifically with face and mouth issues. Additionally, Ma Dan-yang’s classification of LI4 as a Heavenly Star Point further highlights its versatile power.
Yuan-Source Points connect deeply with organ-level Qi
Command Points are especially effective for specific body regions (in this case, face and mouth)
Heavenly Star status cements LI4’s historical reputation as indispensable in clinical practice
These overlapping designations underscore the significance of LI4 in both acute interventions and more routine care protocols.
Large Intenstine 4 Point Location
LI4 is located on the dorsum of the hand, between the first and second metacarpal bones. One practical method to locate it is to have the patient pinch their thumb and index finger together, revealing the muscular bulge at the high point of that junction.
Situated near the midpoint of the second metacarpal bone
Closer to the radial (thumb) border of the hand
Easily palpated due to the prominent mound formed when the thumb and index finger are pressed together
This precise yet simple landmark makes LI4 one of the more straightforward points for both practitioners and patients to locate and stimulate.
LI4 Acupuncture Point Benefits
Classically, LI4 regulates defensive Qi and adjusts sweating, making it a go-to for either inducing or inhibiting perspiration. It’s also praised for its ability to expel wind-cold and wind-heat, reflecting its capacity to release the exterior and help the body rid itself of pathogenic factors.
Regulates face, ears, eyes, nose, and mouth
Alleviates pain through movement of Qi and Blood
Induces labor by promoting uterine contractions
Restores depleted Yang in acute collapse
These diverse actions help explain why texts throughout history have consistently recommended LI4 for a wide array of conditions, from febrile diseases to local pain.
Hegu LI4 Point Indications
Clinically, LI4 is used for everything from headaches and sinus congestion to facial swelling and even mania or mental agitation. By virtue of its connection to the Yangming channel—renowned for its abundance of Qi and Blood—LI4 often addresses pain rooted in stagnation.
Ideal for frontal, one-sided, or generalized headaches
Effective for nasal discharge, nosebleeds, and eye redness
Helpful in jaw problems, lockjaw, and toothache
Addresses external wind invasions accompanied by fever or chills
Whether the issue is acute (like a sudden headache) or chronic (such as recurring facial pain), LI4 consistently shows up in treatment protocols due to its broad-reaching effects.
Needling Technique
Most practitioners needle LI4 perpendicularly to a depth of 0.5–1 cun, though oblique insertions can extend deeper to 1–1.5 cun, often directed proximally. The point’s link to labor induction justifies its contraindication during pregnancy, except under specific medical guidance for birth facilitation.
Perpendicular insertion often chosen for quick dispersion of pain
Oblique insertion may be used to target deeper structures or broader coverage
Manual stimulation (lifting/thrusting, rotating) or electroacupuncture enhances therapeutic impact
Careful needling ensures maximum benefit while respecting the potent physiological responses LI4 can trigger.
Point Combinations
Classically, LI4 is paired with LV3 (Taichong) to form the “Four Gates,” a combination famed for dispersing Qi stagnation and alleviating pain throughout the body. Classical compendiums frequently mention matching LI4 with LI11 (Quchi) to tackle inflammation and high fever. Other synergies include pairing LI4 with KI7 (Fuliu) to manage sweating disorders, adjusting the needling technique between reinforce and reduce for optimal balance.
“Four Gates” synergy addresses widespread pain and muscle tension
LI4 + LI11 for heat, fever, and inflammatory conditions
LI4 + KI7 for regulating abnormal sweating (either excessive or absent)
Such pairings reflect the dynamic and adaptable nature of LI4, allowing practitioners to fine-tune their approach based on individual presentations.
LI4 During Pregnancy
While LI4 (Hegu) is known for its significant therapeutic range—particularly in addressing pain, headaches, and stress-related conditions—this point is traditionally contraindicated during pregnancy unless it is intentionally used by a qualified professional to help induce labor. Because LI4 can stimulate uterine contractions, needling it without proper medical oversight could pose a risk for pregnant individuals. Always consult an experienced acupuncturist or healthcare provider before considering the use of LI4 or any other acupuncture point during pregnancy.
LI4 Acupressure
LI4 Pressure Point
LI4 is one of the most popular hand pressure points for those seeking a pressure point for pain relief—especially for headaches and tension in the upper body. Often referred to as the LI4 pressure point or Hegu pressure point, it’s an accessible and straightforward spot to press when headaches strike or when you experience general discomfort.
Applying Pressure: Locate LI4 between the thumb and index finger on the back of the hand. Gently press with your thumb on one side and your index finger on the other, applying circular pressure for 20–30 seconds.
Benefits: Many people find it an effective headache pressure point, reporting reduced tension around the temples and forehead. It also helps ease stress-related muscle tightness in the neck or shoulders.
Precautions: While self-acupressure can be beneficial, pregnant individuals should avoid strong stimulation of LI4 because of its association with inducing labor. If pain persists or worsens, consult a qualified acupuncturist or medical professional.
This Hegu pressure point is widely recognized in both traditional and modern wellness circles for its quick and convenient application. Whether you’re aiming to calm a headache, reduce facial pain, or simply relax tense muscles, LI4 acupressure is a simple, non-invasive method to explore.
Commentary
Texts like the Great Compendium of Acupuncture and Moxibustion highlight LI4’s unique ability to handle seemingly opposite clinical signs—no sweating versus excessive sweating—by regulating the defensive layer. Likewise, the Ode to Elucidate Mysteries cites using LI4 with LV3 for “cold and heat painful obstruction,” illustrating its dual effect on both interior and exterior syndromes. Its broad application, from postpartum concerns to facial pathologies, exemplifies how thoroughly it spans the scope of acupuncture therapy.
Revered historically for locking or unlocking the body’s pores
Commonly used in analgesia, including scalp, dental, and facial procedures
Known for its ability to instantly move stagnant Qi or Blood, alleviating pain
When viewed through the lens of modern clinical practice, LI4’s enduring reputation is well-earned. Its dynamic capacity to regulate body surfaces, influence internal organ function, and even manage emotional tension solidifies LI4 as a cornerstone in acupuncture treatments—truly embodying the essence of “Joining Valley.”

LI4 Frequently Asked Questions
Where is LI4 located?
LI4 is found on the dorsum (back) of the hand, in the fleshy “valley” between the thumb and index finger. To locate it easily, ask the person to pinch their thumb and index finger together and look for the highest point of the bulge that appears.
Is it safe to needle LI4 if I’m pregnant?
Generally, LI4 is not recommended for routine use during pregnancy because of its well-known action of inducing or stimulating labor. Only under specific medical guidance (such as at term or when labor induction is desired) should it be considered, and always under the care of a qualified acupuncturist or healthcare professional.
How does LI4 help with pain?
LI4 is highly valued for its ability to regulate the flow of Qi and Blood, particularly along the Yangming channel, which is abundant in these vital substances. By promoting circulation, LI4 can alleviate various types of pain—from headaches to dental discomfort—often linked to stagnation.
Can I perform acupressure on LI4 by myself?
Yes, gentle acupressure can be applied to LI4 at home for minor issues like tension headaches or mild stress. However, be aware of the caution regarding pregnancy, and if discomfort persists or worsens, it’s best to consult a licensed acupuncturist or other healthcare professional for further evaluation.
Does LI4 help with colds and fevers?
Classical texts often mention LI4 for releasing external wind-cold or wind-heat, suggesting it can be effective for early-stage or mild cold and flu symptoms. It is believed to help the body sweat out pathogens, but for more severe symptoms, professional medical advice should be sought.
Is there a specific technique to needle LI4?
Practitioners typically insert the needle perpendicularly to a depth of about 0.5–1 cun, or obliquely up to 1–1.5 cun. The exact technique may vary based on the practitioner’s assessment, the patient’s comfort level, and the condition being treated.
Does LI4 work well with other points?
Yes, LI4 is often paired with LV3 (forming the “Four Gates”) for comprehensive pain relief and to move Qi and Blood effectively. It may also be combined with KI7 to regulate sweating or LI11 for addressing heat-related conditions like fever or inflammation. The choice of point combinations depends on each individual’s specific symptoms and overall health profile.
