What is LV5?

LV5 (Ligou) is the fifth point on the Liver channel, on the inner shin about five thumb-widths above the inner ankle bone.

In classical Chinese medicine LV5 is the luo-connecting point of the Liver channel. That means it was taught as the link between the Liver channel and its partner, the Gallbladder channel. Because of that role it appears in every standard point curriculum, even though it is far less famous than LV3 on the foot.

Tradition groups its uses around the lower abdomen and genitals: itching, urinary difficulty, period problems, and the old category of "shan" disorders (groin and testicular pain or swelling). Older texts also used it for local shin discomfort.

Here is the honest verdict. Being old and widely taught tells you a point was valued; it does not show that pressing it works, and it does not show that pressing it is safe for you. Those are separate questions and this page keeps them separate.

On the evidence side there is very little. We found no controlled human trial that tested finger pressure on LV5 on its own for any condition. Where LV5 turns up in acupuncture research it is one needle among many in a package, so nothing can be pinned on this point. Acupressure research in general is small, short and usually unblinded, meaning people knew what they were getting.

So treat LV5 as a comfort measure with a long tradition and thin modern support. It is cheap, self-applied and low-risk for most people on healthy skin. It is not a treatment for genital, urinary or testicular symptoms, all of which need a proper diagnosis. If you press it and feel better, that is worth something; just do not let it delay care for a symptom that deserves attention.

The rest of this page covers where LV5 is, how to press it, what tradition claimed, who should leave it alone, and when to stop and see a doctor.

Where is LV5 and how do you find it?

LV5 sits on the flat inner face of the shin bone (tibia), about five thumb-widths above the tip of the inner ankle bone.

• Sit down and bare the leg. Sit with your foot resting on the other knee or on a low stool, so you can reach your inner lower leg comfortably.
• Find the inner ankle bone. Feel the hard knob on the inside of your ankle, called the medial malleolus. Put a fingertip on the highest point of that knob — that is your starting mark.
• Measure up the shin. Lay four fingers of your other hand across the inner leg, just above the ankle knob. Four fingers together is about three cun (body-inches). Then add two of your own thumb-widths above them.
• That is about five cun. In most adults the spot lands roughly 10 to 13 cm above the ankle knob, but use your own hand rather than a ruler, since cun are scaled to your body.
• Slide onto the bone face. Feel the sharp front edge of your shin bone, then move your finger backwards about a thumb-width onto the smooth flat surface on the inner side. LV5 is on that flat face, not in the soft calf muscle behind it.
• Check the feel. Under your fingertip you should feel firm bone with a thin layer of skin over it. Gentle pressure often feels tender or slightly achy here, which is normal for points directly over bone.

A useful cross-check: LV5 is higher up than it feels like it should be. The midpoint between your ankle knob and the bony bump at the inner edge of the knee is roughly seven to eight cun, so LV5 sits clearly below halfway.

If you are not certain, stay with what is agreed: the flat inner surface of the shin, about a third of the way from ankle to knee. Everything on this page is finger pressure only, so pinpoint precision matters less than staying off bruised or broken skin.

How do you apply pressure to LV5?

1. Get settled first. Sit somewhere you can hold the position for a couple of minutes without straining your back. Rest the foot on the opposite knee or on a stool.
2. Warm the area. Rub the inner shin briskly with your palm for a few seconds. Skin over bone is thin, and warming it makes pressure more comfortable.
3. Use a finger pad, not a nail. Place the flat pad of your thumb or index finger on the spot. Keep nails short so you do not scratch the skin.
4. Press lightly at first. Lean in slowly until you feel a dull ache or firm tenderness. On a scale of ten, aim for about three or four. LV5 sits on bone, and the bone covering (periosteum) is sensitive, so this point needs less force than a fleshy point.
5. Hold or circle gently. Either hold steady pressure for 30 to 60 seconds, or make small slow circles without dragging the skin.
6. Breathe slowly through it. Let your out-breath be a little longer than your in-breath. Much of the calming effect people report comes from sitting still and breathing.
7. Release gradually. Ease off over a few seconds rather than lifting straight away, then rest the leg for a moment.
8. Do both legs. LV5 is a paired point, one on each inner shin. Give each side the same time.
9. Repeat sensibly. Once or twice a day, up to two or three minutes per leg, is plenty. More is not better here.

Stop straight away if the pain turns sharp, burning or electric, if you feel pins and needles running into your foot, if the skin reddens and stays red, or if a bruise forms. Give the area at least a day off after any bruising.

Never break the skin. This page is about finger pressure only — no needles, no heat applied to the skin, no suction devices. If you want needling, that is a trained practitioner's job, not a home one.

What is LV5 traditionally used for?

• Genital itching and irritation. This is LV5's best-known classical use, especially itching around the vulva or scrotum. There is no human trial testing finger pressure on LV5 for itching, and persistent genital itching needs a diagnosis, since thrush, eczema, lichen sclerosus and infection all look similar from the outside.
• Groin and testicular pain. Old texts list LV5 for "shan" disorders — pain, swelling or dragging sensations in the groin and testicles. No modern evidence supports pressing it for this. Sudden severe testicular pain is a medical emergency, not a self-care situation.
• Urinary difficulty. Tradition used LV5 for trouble passing urine, dribbling or a sense of incomplete emptying. Nothing in the research literature tests this point for urinary symptoms, and these complaints have treatable causes worth finding.
• Period pain and irregular cycles. LV5 appears in classical prescriptions for menstrual problems. Worth knowing: the acupressure point that has actually been tested in trials for period pain is SP6, a different point three thumb-widths above the ankle bone, and even there the trials are small and unblinded. LV5 itself has not been tested that way.
• Feeling wound up or irritable. The Liver channel is linked in tradition to frustration and tension, so LV5 is sometimes suggested for stress. Any calming you notice is most likely from the few quiet minutes of slow breathing, which is a real benefit but not a point-specific one.
• Local shin and inner-leg aching. Gentle pressure and rubbing over a tender spot on the inner shin can feel soothing in the moment. That is ordinary massage comfort rather than anything particular to LV5.
• Channel-pairing use. As the luo-connecting point, LV5 was chosen to balance the Liver and Gallbladder channels. This is a theory-driven reason for picking the point, not a tested one.

In short: a rich tradition, almost no point-specific human evidence. Use LV5 as comfort alongside proper care, never instead of it.

Are there tips for using LV5 effectively?

• Measure with your own hand. Cun are scaled to the person being measured. Use your own four fingers and your own thumbs, not a partner's hand and not a tape measure.
• Mark it once. When you have found a tender spot you trust, dab it with a washable pen. After a few sessions you will find it without measuring.
• Go lighter than you expect. LV5 lies directly on bone. Heavy pressure here causes bruising and lingering soreness rather than better results.
• Let your breath lead. Press as you breathe out, soften as you breathe in. It keeps the force steady and stops you bearing down too hard.
• Treat both legs. Tradition and simple balance both favour working the point on each side for the same length of time.
• Pick a calm moment. Evening, after a shower, with warm skin, is more comfortable than a cold shin at a desk.
• Keep a short diary. Note the date, how long you pressed, and how you felt an hour later. Over a few weeks this tells you far more than any claim on a video.
• Give it a fair trial, then decide. Two weeks of daily use is enough to judge. If nothing has shifted, stop rather than escalating the pressure.
• Combine it with the basics. Sleep, hydration, movement and warmth do more for period pain and tension than any single point. Acupressure sits on top of those, not instead of them.
• Check the skin each time. Look before you press. A new rash, a broken patch, a swollen vein or a bruise means skip the point that day.
• Keep expectations modest. The honest aim is a few minutes of calm and perhaps a little less tension, not a change in a diagnosed condition.

What do people get wrong with LV5?

• Expecting a cure. This is the big one. LV5 is a comfort measure with a long history and very thin modern evidence. No acupressure point cures itching, infection, infertility or urinary disease.
• Confusing it with SP6. SP6 is three thumb-widths above the ankle bone and sits just behind the back edge of the shin bone. LV5 is five thumb-widths up and on the flat inner face of the bone itself. Videos mix these up constantly.
• Pressing too hard on bone. People treat LV5 like a muscle point and dig in. The result is a tender, bruised shin. Moderate pressure is the ceiling here.
• Using someone else's thumb to measure. Cun are proportional to your own body. Borrowing a partner's hand can put you a couple of centimetres off.
• Ignoring a painful calf. A calf that is swollen, warm, red or newly painful can mean a blood clot (deep vein thrombosis). Massaging that area is dangerous. Get it checked instead.
• Pressing over damaged skin. Varicose veins, eczema, an ulcer, a shaving nick or a healing surgical wound on the inner shin all mean leave the point alone.
• Delaying care for genital symptoms. Persistent itching, discharge, a lump, blood in the urine or testicular pain need examining. Weeks of self-pressure while the problem develops is the real harm.
• Doing it for too long. Ten minutes of grinding on one spot does not multiply the effect. A minute or two per leg is the sensible dose.
• Assuming old means safe. Traditional standing says nothing about whether pressure is safe over your particular leg today.
• Trying to needle at home. Nothing on this page is a needling instruction. Skin-breaking techniques belong to trained practitioners, full stop.

What does the research on LV5 actually say?

Very little, and we will not pretend otherwise. We found no controlled human trial testing finger pressure on LV5 by itself for itching, urinary symptoms, period pain or anything else.

Where LV5 appears in acupuncture studies, it is almost always one point in a multi-point prescription chosen by a practitioner. Those study designs cannot separate out what any single point contributed. Even a positive result in such a trial tells you nothing specific about LV5.

The wider acupressure literature has the same weaknesses everywhere. Most trials are small, run for days or weeks rather than months, and are unblinded, meaning participants knew whether they were receiving pressure. Expectation alone shifts self-reported symptoms like pain and itch, so unblinded results are easy to overstate.

For contrast, it helps to know what good evidence looks like. PC6 on the inner wrist has been tested in many randomised trials for nausea and vomiting, including in pregnancy and after surgery, and reviews find a real if modest benefit. That is the strongest case in the whole acupressure literature. LV5 is nowhere near it.

So the honest grading is: insufficient human evidence for LV5 specifically, alongside a solid traditional standing as the luo-connecting point of the Liver channel. Those two things sit on separate axes and neither rescues the other.

What this means in practice is simple. Pressing LV5 is a low-cost, low-risk thing to try on healthy skin, and you may find it calming. It is not a reason to postpone seeing a clinician about genital, urinary or menstrual symptoms, and it should not replace any treatment you have been prescribed. If future trials test this point properly, this page will say so.
