What is LV11?

LV11 (Yinlian) is a Liver channel point on the inner thigh, just below the groin, beside the adductor longus tendon.

Its Chinese name, Yinlian, is usually translated as "Yin Corner" or "Yin Screen". It is one of the fourteen points on the Liver channel, which classical texts link to the genitals, the lower abdomen and the inner leg. The channel is described as running up the inside of the leg, through the groin and on to the lower trunk, which is why points in this area were grouped with menstrual, urinary and genital complaints.

Within tradition LV11 is a minor point. Every curriculum lists it because the channel has to be learned in full, but it is used far less often than neighbours such as LV3 or SP6. Older texts mention it for irregular periods, genital itching and pain in the inner thigh, and some classical passages connect it to difficulty conceiving.

Two things are worth saying once, clearly, before the rest of the page. First, long traditional use is not evidence that a point works; a claim can be repeated for two thousand years and still be wrong. Second, long traditional use is not evidence that a point is safe either, because the texts were written before anyone mapped the femoral artery, the femoral nerve or the groin lymph nodes that sit close to this spot.

The honest verdict on evidence: there is essentially no human research on LV11 for anything. Acupressure research overall is dominated by small, unblinded, short-term studies, and the few points with genuinely decent trial support — PC6 for nausea is the clearest — are not this one. Treat LV11 as a comfort measure and a piece of traditional anatomy, not as a treatment.

Everything described here is self-applied finger pressure on your own body. Nothing on this page involves needles, heat or anything that breaks the skin.

Where is LV11 and how do you find it?

LV11 sits on the inner thigh, about two thumb-widths below the top of the pubic bone, at the outer edge of the adductor longus tendon.

• Sit and open the hip. Sit on a chair or the floor, let the knee fall outward and the sole of the foot turn in. This brings the inner thigh forward where you can reach it comfortably.
• Find the pubic bone. Press gently along the midline at the very bottom of your abdomen until you feel the firm front edge of the pubic bone. That upper edge is your height reference.
• Find the adductor tendon. Squeeze your knees together against your own hand. A thick cord stands out at the very top of the inner thigh. That is the adductor longus tendon, the main landmark for LV11.
• Drop down two thumb-widths. From the level of the top of the pubic bone, move about 2 cun — roughly two thumb-widths, or 4 cm — straight down the thigh.
• Settle on the outer edge. At that level, LV11 is taken at the outer (front) border of the adductor longus, in the soft hollow beside the tendon rather than on top of it.
• Check for a pulse first. If you feel a steady beat under your fingers, you have strayed toward the femoral artery. Shift back toward the inner thigh until the beating stops.

Sources differ slightly on the exact depth and the distance from the midline, so treat the tendon edge and the two-thumb-width drop as the agreed landmarks and stay conservative. Keep contact light while you search.

This is a private and sensitive area with large blood vessels and lymph nodes nearby. Locate it on yourself, in private, with the flat pad of a finger — never with a fingernail, a tool or anything sharp.

How do you apply pressure to LV11?

1. Get comfortable and private. Sit with the knee relaxed outward. Work over thin clothing or bare skin, whichever feels less awkward, and keep the session to yourself.
2. Warm the area first. Stroke the inner thigh for twenty or thirty seconds with a flat palm. Warm, relaxed muscle tolerates pressure far better than cold, guarded muscle.
3. Use a broad contact. Place the flat pads of your index and middle fingers over the spot beside the tendon. No nails, no knuckles, no massage gun, no hard tools.
4. Confirm there is no pulse. Rest still for a few seconds. If you feel a beat, move your fingers toward the inner thigh and re-check before pressing.
5. Press gently. Sink in slowly to a pressure you would rate about 3 or 4 out of 10 — noticeable, never sharp. The groin needs less force than a shoulder or a foot.
6. Hold and breathe. Keep steady pressure for 30 to 60 seconds while breathing slowly. You can add slow, small circles instead of a static hold if that feels better.
7. Release slowly. Ease off over a couple of seconds rather than lifting off suddenly, then stroke the area again.
8. Repeat sparingly. Two or three rounds per side, once or twice a day, is plenty. There is no benefit in grinding away for ten minutes.

Stop immediately and do not continue if you feel a pulse under your fingers, electric or shooting sensations down the leg, numbness, pins and needles, or any sharp pain. Those signals mean you are on a vessel or a nerve, not on soft tissue.

Stop and leave the area alone if the skin reddens and stays red, if a bruise forms, or if the groin feels more sore the next day. Lasting soreness after light pressure is a reason to let it settle for a week, not a reason to press harder.

What is LV11 traditionally used for?

• Irregular or painful periods. Classical texts group LV11 with menstrual irregularity because the Liver channel is said to govern the lower abdomen and genitals. No human trial has tested LV11 for menstrual symptoms, so this is tradition only. Some acupressure studies on other points, such as SP6, report short-term pain relief, but those results do not transfer to this point.
• Genital itching, pain and discharge. Older sources list LV11 for itching and discomfort in the genital area. There is no modern evidence for it, and these symptoms usually have a treatable cause — thrush, a skin condition or an infection — that needs a diagnosis rather than finger pressure.
• Inner thigh and groin discomfort. LV11 sits directly on the adductor muscle group, so gentle pressure there can feel like ordinary muscle massage and may ease a tight, aching inner thigh. That is a plausible soft-tissue effect, not proof that the point itself does anything special.
• Numbness or weakness of the thigh. Tradition mentions LV11 for heaviness and numbness in the leg. Modern practice would send persistent numbness to a doctor, because it can come from the back, a nerve or circulation.
• Difficulty conceiving. Some classical passages connect LV11 with infertility, usually in the context of heat treatments that this library does not cover. There is no human evidence that pressing LV11 affects fertility, and fertility problems deserve proper medical investigation.
• Urinary difficulty. A minor traditional association, with no supporting trials. Trouble passing urine is a symptom to have assessed, especially if it comes on quickly.

Taken together, the realistic expectation is modest: a warm, relaxed inner thigh and a few quiet minutes. Anything beyond that is unproven for LV11. Use it alongside medical care, never instead of it.

Are there tips for using LV11 effectively?

• Make the tendon stand out. Squeeze your knees together for a second before you search. The adductor longus cord pops up clearly and gives you a reliable edge to work from.
• Warm before you press. A warm shower or a few minutes of walking relaxes the adductors, so you need much less force to reach anything useful.
• Less force, more time. The groin is thin-skinned and vessel-rich. A light hold for a minute is safer and usually feels better than a hard dig for ten seconds.
• Keep breathing out. Pressing on a long, slow exhale lets the muscle release instead of bracing against your fingers.
• Pair it with a stretch. If your inner thigh is tight, a gentle butterfly or seated groin stretch afterwards often does more for the tightness than the point work alone.
• Work both sides. If you use the left, use the right. Even pressure feels more balanced and stops you fixating on one sore spot.
• Keep it private and self-applied. This is an intimate area. Do it alone, over clothing if you prefer, and never on someone else without clear consent and good reason.
• Track honestly for two weeks. Note the symptom score before and after. If nothing shifts, let the point go rather than pressing harder or longer.
• Give skin a day off. If the area is tender or pink from yesterday, skip it. Repeated pressure on irritated skin in a warm, folded area invites soreness.
• Choose the easier point when you can. For general relaxation, points on the hand, forearm or foot are far simpler to reach and carry none of the groin's anatomical complications.

None of this makes LV11 a treatment. These tips simply make a short, low-risk self-massage more comfortable and less likely to go wrong.

What do people get wrong with LV11?

• Expecting a cure. The biggest error is treating LV11 as a fix for infertility, period problems or genital symptoms. Nothing in the evidence supports that, and the delay in getting a diagnosis is the real harm.
• Pressing on a pulse. The femoral artery runs close by in the groin. If you feel beating under your fingers, you are in the wrong place — move toward the inner thigh and start again.
• Digging into a gland. Groin lymph nodes feel like small movable beans. People mistake them for the point and press hard. A lump in the groin should be seen by a doctor, not massaged.
• Confusing it with its neighbours. LV12 sits higher, at the groin crease, and SP12 and SP13 are nearby too. Working at the crease instead of two thumb-widths below it means you are not on LV11 at all.
• Using tools or nails. Massage guns, pens and fingernails have no place on thin groin skin. Flat finger pads only.
• Going too hard because it is "deep". The muscle is thick but the structures above it are not. Heavy pressure here causes bruising, not better results.
• Trying heat or needles at home. Classical texts for this point mention heat methods. Those are not self-care and are not described here. Finger pressure is the only thing this page covers.
• Pressing through sharp or electric pain. Shooting sensations down the leg mean a nerve, not a blocked channel. Stop rather than push on.
• Ignoring one-sided swelling. A leg that is swollen, warm and painful needs urgent assessment, not massage, because a clot can be the cause.
• Stopping prescribed treatment. People sometimes trade their medication for a point routine. Keep the medication and ask your doctor before changing anything.

What does the research on LV11 actually say?

There is no useful human research on LV11 specifically. A search of the acupuncture and acupressure literature turns up no controlled trial, and no sizeable case series, that tested this point on its own for menstrual problems, genital symptoms, fertility or thigh pain. That is the honest position, and inventing a study to fill the gap would be worse than leaving the gap visible.

What that means in practice: the claims attached to LV11 rest on classical texts and on channel theory, not on measured outcomes in people. The point does appear inside multi-point acupuncture protocols in some gynaecology research, but when a protocol uses eight or ten points at once, a positive result says nothing about any single one of them. You cannot pull LV11 out of that mix and call it supported.

The wider picture is worth knowing. Acupressure research as a whole is dominated by small studies, often with fewer than a hundred participants, usually unblinded, and usually measuring outcomes only over days or weeks. Blinding is genuinely hard, because a person can tell whether someone is pressing on them, and that opens the door to strong placebo and expectation effects. The clearest exception is PC6 for nausea and vomiting, where repeated controlled trials and systematic reviews do support a real, if modest, effect. LV11 has nothing comparable behind it.

There is a separate body of sports-medicine work on the adductor muscles, covering soft-tissue massage and stretching for groin strain. That literature is about muscle treatment in general, not about acupressure points, so it cannot be used to validate LV11. It does, however, make it reasonable to say that gentle massage of a tight inner thigh may feel good.

If better evidence appears, this page will change. Until then, grade LV11 as unproven and use it accordingly.
