Quick Answer
LI4 Hegu, often translated as Joining Valley, is a Large Intestine point in the hand web. It is famous, easy to reach, and easy to misuse; pregnancy caution and severe-head-symptom safety come before any pressure idea.
Safety Decision
Stop before pressure if the body area is injured, the symptom is severe or unusual, or qualified care should come first.
Continue only as a short, comfortable, education-only routine after reading the locator and stop signs.
LI4 HeguBefore You Try This
LI4 is educational and not medical advice. Avoid LI4 pressure during pregnancy unless a qualified professional says otherwise, and avoid pressure on injured, bruised, swollen, numb, or painful hand tissue.
Ask a qualified professional for pregnancy, labor-related questions, severe or sudden head symptoms, neurological signs, medication concerns, chronic illness, or symptoms that are unusual or worsening.

Is This the Right Page to Read Now?
This acupoint page fails if the Joining Valley on the back of hand in the Large Intestine family locator becomes a treatment shortcut, a stronger-pressure target, or a replacement for the named safety stop signs.
Read the pregnancy and hand-tissue cautions first, then choose headache, sinus, printable, or Safety only if the context remains mild. Then choose read-only, one brief comfortable contact, a printable card, or a safety stop.
Diagram Notes
The marker highlights LI4 Hegu, Joining Valley, on a back of hand locator view; its landmark cue is "In the web between thumb and index finger, on the fleshy mound rather than on the bone edge." Use it with the safety cues rather than treating the marker as clinical precision.

How to read the LI4 locator
- Start with the broad area: back of hand.
- Compare the written landmark: In the web between thumb and index finger, on the fleshy mound rather than on the bone edge.
- Use the marker as orientation, then let comfort and the avoid during pregnancy unless a qualified professional says otherwise caution decide whether to stop.
The Joining Valley locator uses a licensed educational anatomy base for the back of hand; it is not a clinical locator or personal safety clearance.
Why This Page Gets Extra Attention
Reader Scenario
A reader knows LI4 is easy to find on the hand but has not noticed the pregnancy caution or the risk of hard squeezing.
Common Misread
Do not treat the tender hand web as proof that LI4 is correct or safe; tenderness is not a locator method.
Editorial Call
LI4 is a flagship because an easy landmark can create false confidence, especially when pregnancy or hand injury matters.
Best Next Choice
Choose the headache guide, stress guide, printable card, or pregnancy safety page before any hand pressure.
Use the hand-web locator to choose the broad mound, then let pregnancy and pain cautions decide.
What LI4 Hegu is called
LI4 is the point code. Hegu is the pinyin name. Joining Valley is a common English rendering that points to the valley-like space between thumb and index finger. The name helps readers recognize the same point across charts, printable cards, headache articles, and traditional meridian references. The name is not a result claim. On this page, Hegu is first an identity anchor: a way to keep the hand-web point stable while the safety decision stays visible.
Why LI4 gets searched so often
LI4 is easy to reach, easy to draw, and common in short lists for head tension, stress, sinus pressure, and general hand acupressure. That popularity creates risk because a familiar point can feel automatically safe. The public article needs to answer the search while slowing it down. The useful question is not only where LI4 is, but whether this reader should use pressure today, whether pregnancy changes the answer, and whether the symptom is too strong for a point page.
Broad location in the hand web
For reader education, think of LI4 as the fleshy web area between the thumb and index finger, on the back-of-hand side. The locator should not send the reader hunting for the most painful pinch. The safer cue is broad, comfortable contact on healthy tissue. Bone edges, sharp nerve-like sensations, bruising, swelling, numbness, cuts, infection, or recent hand strain should change the page to reading-only. Tenderness is not proof that the point has been found correctly.
Pregnancy caution belongs near the top
LI4 carries a strong pregnancy caution in many traditional and professional references. A public self-acupressure page should not bury that warning below a long discussion of head tension. If the reader is pregnant, could be pregnant, helping someone who may be pregnant, or asking about labor, this page should not become a home technique page. The next step is qualified guidance, not a stronger pinch, a printable card, or a combination routine.
When gentle LI4 pressure might fit
A low-risk LI4 moment is narrow: the reader is not pregnant, the hand skin is healthy, the concern is mild and familiar, and stopping immediately is easy. Pressure should be broad and comfortable. A brief hold, release, and reassessment is enough. Do not use LI4 when head pain is sudden, severe, new, unusual, linked with injury, accompanied by neurological signs, vision change, fever with serious illness signs, faintness, chest symptoms, or anything that makes the reader worried.
Do not read LI4 as a headache button
Many people meet LI4 through a phrase like pressure point for headache. That phrase is too short for a health decision. Head pain can be ordinary tension, but it can also signal something that needs urgent or professional care. LI4 can be explained as a traditional and wellness-context point, but it should not be written as a treatment button. The page should make it normal to leave for a safety page before any hand pressure happens.
common mistake: forcing Hegu
The most common LI4 misuse is forcing the web space because the hand feels accessible. A reader may squeeze while scrolling, press until the tissue aches, or keep testing both hands to find the tender spot. That is not careful acupressure. For LI4, the hand should remain relaxed, warm, and comfortable. Sharp pain, spreading ache, tingling, numbness, bruising, color change, or anxiety about the location means stop. Stronger pressure is not a better locator.
If you pressed LI4 too hard
Release first. Do not press again to check whether the point was correct. Look for bruising, swelling, numbness, tingling, color change, heat, skin break, or pain that spreads into the thumb, index finger, wrist, or forearm. A little temporary soreness from overdoing pressure is a signal to rest the hand, not proof that LI4 was activated. If symptoms persist, feel sharp, follow an injury, or worry the reader, the next step is qualified care rather than another point.
How LI4 relates to GB20 and temple-area pages
LI4 often appears beside GB20 or temple-adjacent points in head-tension content. That relationship should be explained as a reading path, not a multi-point prescription. LI4 is a hand point with pregnancy caution and hand-tissue cautions. GB20 is a base-of-skull point where dizziness, neck symptoms, and neurological signs matter. A reader comparing the two should open one page at a time and let the stricter stop sign control the routine.
How LI4 relates to LI20 and sinus pressure
Sinus-pressure articles may mention LI4 with LI20 near the nose. The pairing can help readers understand why a hand point appears in face-related writing, but it does not identify the cause of congestion or infection signs. LI20 has face-skin and eye-adjacent cautions, while LI4 has hand-web and pregnancy cautions. If fever, severe facial pain, infection signs, vision symptoms, swelling, or persistent symptoms are present, the right path is safety or care rather than adding both points.
How LI4 compares with PC6
LI4 and PC6 are both easy to reach, which is why readers may collect them quickly. They are not interchangeable. LI4 is in the thumb-index web and carries a pregnancy caution in this atlas. PC6 is on the inner forearm and is commonly discussed in nausea and travel contexts. The better relationship is educational comparison: read the body area, read the caution, and avoid building a stronger routine simply because both points are accessible.
What the Chinese name adds
Hegu can be remembered as Joining Valley, which fits the hand-web image. That cultural memory is helpful, but it can also create false confidence if the name feels too intuitive. A memorable name does not make the point safe for every reader. The name page should help readers connect Chinese characters, pinyin, English rendering, and point identity. This article keeps that cultural value separate from the decision to press.
Using LI4 in a short routine
A safe public routine should be shorter than the article. Read the quick answer, check pregnancy and hand tissue, locate the broad web area, use comfortable contact only if the situation remains low-risk, release, and reassess. Do not stack LI4 with face, neck, wrist, or leg points in the same first pass. If the reader wants a combination for headache, sinus pressure, or stress, the next page should explain why each point was chosen and when the routine stops.
Acupuncture, moxa, and cupping boundary
LI4 is also an acupuncture point in professional practice, but this site does not teach needling. It also does not teach moxibustion, cupping, gua sha, labor induction methods, or procedural sequences on the hand. Those questions change the risk profile and belong with qualified professionals. The public LI4 page may mention professional and traditional contexts only to explain why the point is known, not to instruct readers in techniques beyond gentle non-invasive pressure.
What sources support beside the evidence note for LI4
Reader use: for LI4 Hegu, the recalled sources support the exact article identity at /acupoints/li4-hegu/, the displayed point name, and the broad locator language used on this page rather than a generic chart. Reader use: for LI4 Hegu, the named sources support the page-specific boundary "LI4 is educational and not medical advice. Avoid LI4 pressure during pregnancy unless a qualified professional says o..." and the article value "A LI4 article that explains the hand-web name, why fame increases misuse risk, how LI4 relates to GB20, LI20, and hea..." without promising a result. Read these notes as traceability for this one point page; they cannot inspect the reader's skin, medication, pregnancy status, chronic illness, pain pattern, urgency, or whether pressure belongs today.
What LI4 does not mean for pain care
LI4 can appear in pain, headache, and tension articles, but this page does not tell a reader to manage pain with acupressure. Pain that is severe, sudden, unexplained, persistent, linked with injury, associated with weakness or numbness, or worrying in any way should not be routed through a hand point. LI4 can still be useful as literacy: it helps the reader identify a famous point and ask better questions without converting that knowledge into a treatment plan.
Using the printable LI4 card responsibly
The printable LI4 card should be a memory cue after the full page has been read. It can remind the reader of Hegu, the hand-web area, the pregnancy caution, and the stop signs. It should not travel alone as a tip that says press here for headache. If context changes, especially pregnancy, severe symptoms, hand injury, numbness, skin irritation, or uncertainty about location, the card is no longer enough. Return to the full article or Safety.
When not to compare more charts
If LI4 still feels uncertain after the written landmark and locator, do not solve uncertainty by opening five more diagrams. More charts can make the hand web look more precise than it feels. Step back: identify the broad web space, check whether the tissue is healthy, confirm pregnancy status is not a concern, and decide whether reading-only is the right mode. Confusion is useful information. It means the page should slow the reader down.
Questions to bring to qualified care
When LI4 seems relevant but the situation is not clearly low-risk, use the page to prepare questions. Ask whether hand acupressure is appropriate with pregnancy, headache pattern, medication use, neurological symptoms, hand injury, chronic illness, or child use. Ask what symptoms should stop home pressure. Ask whether a professional technique such as acupuncture is appropriate at all. These questions are a better outcome than pretending a point article can clear personal risk.
A Real visit: desk tension after screen work
A reasonable LI4 reading scenario is a non-pregnant adult with familiar mild hand and shoulder tension after screen work, healthy hand skin, no alarming head symptoms, and no need to delay care. The article helps that reader avoid turning tension into a long point list. They may read LI4, check the headache or desk-tension guide, use brief comfortable contact if everything still fits, then stop. If the story becomes stronger or stranger, LI4 stops being the right page.
Why labor claims are outside this page
Some readers find LI4 while searching for labor induction or late-pregnancy pressure points. That is exactly the moment this public page should narrow, not expand. The atlas cannot know gestational age, pregnancy risk, fetal status, medication, provider instructions, or whether any pressure is appropriate. LI4 may be discussed in professional acupuncture contexts, but that does not create a home method. If labor, pregnancy discomfort, induction, breech positioning, contractions, bleeding, fluid leakage, severe pain, or reduced fetal movement is part of the question, the useful next step is qualified maternity care or a pregnancy safety page, not a hand-web technique.
Hand injury changes the decision
LI4 looks simple because it sits on the hand, but the hand is not a neutral surface. Recent sprain, thumb strain, tendon irritation, swelling, arthritis flare, numbness, tingling, cuts, burns, infection, bruising, or loss of normal sensation should move the page to reading-only. A reader should not press around injury to see whether LI4 helps discomfort. The point article can still be useful: it names the area and explains why pressure is not the right action today. In a high-trust page, choosing not to touch an injured hand is part of the content quality.
Why LI4 combinations need a reason
A combination should never be a pile of famous points. If LI4 appears beside GB20 for head tension, the reason is a hand-and-neck comparison with different cautions. If it appears beside LI20 for sinus pressure, the reason is hand-to-face context with infection and eye-adjacent caution. If it appears beside PC6 for stress or travel unease, the reason is access and body-awareness, not a stronger effect. A useful combination page should say which point to read first, which stop sign overrides the rest, and why adding points may be less helpful than stopping.
How to record a low-risk LI4 attempt
If the reader uses LI4 in a low-risk moment, the record should stay modest. Note the context, whether pregnancy was not a concern, whether the hand skin was healthy, which hand-web area was touched, how gentle the contact felt, when pressure stopped, and whether soreness, tingling, or skin change appeared. Do not record the experience as proof that LI4 worked or failed. Record it as context. That kind of note can help the reader notice overpressure habits and can support a clearer conversation if head tension, hand discomfort, or medication questions later become relevant.
What a short answer usually misses
A short LI4 answer can show a hand diagram and say that Hegu is between the thumb and index finger. That is not enough for this site. It misses pregnancy caution, severe-headache stop signs, the difference between hand soreness and point precision, related face and neck points, and the boundary between acupressure and professional acupuncture. This article is longer because LI4 is familiar enough to be misused quickly. The editorial job is to make the common point slower, clearer, and safer without turning it into medical advice.
How LI4 differs from the Large Intestine meridian page
The meridian page can explain why LI4 belongs to the Large Intestine route and how it relates to LI20 or other points in the family. The LI4 page has a different job. It must stay close to one body area, one point name, one locator, one pregnancy caution, and one next decision. Do not infer digestive or head symptoms from the meridian label. Meridian context is a map for reading traditional language, not a condition-mapping shortcut. If the reader wants route-family context, open the meridian page after this point-specific safety check.
What the locator leaves out
The LI4 locator does not show how hard the reader is squeezing, whether the web tissue is irritated, whether a joint is inflamed, whether a nerve-like sensation is spreading, whether pregnancy is possible, or whether the head symptom is concerning. That missing information matters more than the marker. A good locator helps orientation, then hands control back to the text: stop for pregnancy questions, stop for unhealthy hand tissue, stop for severe or unusual symptoms, and stop when the point feels uncertain. The image should never outrank the caution.
The decision after reading LI4
After reading LI4, the reader should be able to choose one path. Stay reading-only because pregnancy, symptom severity, hand tissue, or uncertainty creates risk. Open the headache, sinus, or desk-tension guide only for mild scenarios. Compare one related point for education, not for a stronger routine. Use the printable card only after the full caution is understood. Or leave the atlas for qualified care. A famous point earns trust when it makes stopping feel normal.
Questions Readers Usually Ask
Why is LI4 so often mentioned?
LI4 is famous and easy to locate broadly, but fame is not safety clearance. The hand-web location, pregnancy caution, and symptom context still decide how to read the page.
Can LI4 be used with GB20 for headaches?
Only as a mild-context reading relationship. Sudden, severe, unusual, or neurological head symptoms should leave the atlas for urgent or qualified care.
Why does the LI4 page keep mentioning pregnancy?
Because pregnancy changes the risk boundary. The site does not give pregnancy or labor instructions, and LI4 should stay read-only unless qualified care says otherwise.
What if LI4 feels sharply tender?
Stop. Sharp tenderness is not proof of correct location. It can mean the pressure is too much or the tissue is not suitable.
