What is LV13?

LV13, or Zhangmen, is a point on the side of the trunk, at the pointed free end of the 11th rib. Its name is usually translated as "Completion Gate" or "Camphorwood Gate".

In classical Chinese medicine LV13 carries a lot of weight. It is the Front-Mu (alarm) point of the Spleen, the Hui-Meeting point of the Zang (solid) organs, and a crossing point of the Liver and Gallbladder channels. Because of that, it is taught in every acupuncture curriculum and listed in the major classical texts. Traditionally it was used for abdominal fullness, poor appetite, loose stools, and the pattern practitioners call "Liver overacting on the Spleen" — digestive upset that flares with stress or frustration.

Here is the honest verdict on the evidence. Long traditional standing tells you the point has been used and trusted for centuries. It is not evidence that pressing it produces a specific effect in the body, and it is not evidence that pressing it is safe for everyone. Those two things have to be checked separately, and for LV13 there is almost nothing in the way of human research testing the point on its own.

What research exists uses LV13 inside multi-point acupuncture protocols for digestive complaints, so no effect can be traced back to this point. The wider acupressure literature is mostly small, unblinded and short-term, which means results are easily inflated by expectation and attention.

The practical safety point matters more here than at most points. LV13 sits over the lowest ribs, with the spleen beneath on the left and the liver beneath on the right. Gentle finger pressure on healthy tissue is low-risk. Deep digging is not sensible, and some people should skip this point entirely — see "Who should avoid it" below.

Treat LV13 as a low-cost comfort technique that may help you relax and breathe lower into the belly. Do not treat it as a treatment for abdominal pain, liver disease or digestive illness.

Where is LV13 and how do you find it?

LV13 sits on the side of your trunk, at or just below the pointed free end of the 11th rib — the lower of the two short "floating" ribs you can feel in your side.

• Sit or lie on your side. Let the trunk soften. If you are tensing your waist muscles, the rib tip is much harder to feel.
• Find your lowest ribs. Slide a flat hand down your side, below the ribcage arc at the front, then move backwards and upwards towards your back. You will feel one or two short rib ends that are not joined to anything at the front.
• Pick the upper of the two floating ends. The very lowest free tip is the 12th rib, which marks GB25. LV13 is the next one up, at the 11th rib's tip.
• Settle in the soft spot. The point is at the tip itself and the small hollow just under and in front of it, not on the hard rib shaft.
• Use the classic elbow check. Let your arm hang, bend the elbow and tuck it against your side. The tip of the elbow lands close to LV13 on most body shapes. Use this as a rough guide, then confirm by feel.

In traditional terms the point is on the lateral abdomen, level with roughly the lower border of the ribcage at the side. If you cannot confidently count ribs on yourself, that is common — many people cannot, especially if there is more tissue over the area. In that case use the elbow landmark and the softest hollow you can find under a short rib end, and keep the pressure light.

You will usually notice a mild dull ache or a sense of fullness when you are on the spot. Sharp, stabbing or radiating pain means move off, not press harder. Never try to reach "under" the rib edge with a hooked finger.

How do you apply pressure to LV13?

1. Get comfortable first. Sit, or lie on your back with knees bent. A relaxed belly wall means you can work gently and still feel the point.
2. Use flat fingers, not a fingertip point. Place the pads of two or three fingers over the spot. A broad contact spreads the load over soft tissue and the rib end.
3. Press lightly at first. Sink in slowly over a few seconds until you feel a mild, dull, tolerable pressure. On this part of the body, light to moderate is the ceiling. Firm digging is not appropriate here.
4. Hold and breathe. Keep steady pressure for about 30 seconds to one minute while breathing out slowly. You can add a small, slow circular movement instead of a static hold if that feels better.
5. Ease off gradually. Release over a couple of seconds rather than lifting suddenly.
6. Do both sides. The point is on the left and right. Many people find one side more tender.
7. Repeat sensibly. Two or three short sessions a day is plenty. There is no benefit in grinding away for ten minutes.

Timing matters a little. Avoid working this area straight after a large meal, when the stomach is full and the whole region feels tight. Wait an hour or so.

Stop immediately and do not continue if you feel sharp or stabbing pain, pain that travels into the back or shoulder, nausea that worsens, light-headedness, or any tenderness that lingers afterwards. Stop too if the skin reddens oddly or bruises. Bruising over the lower ribs after light pressure is not normal and is worth mentioning to a doctor, especially if you take blood-thinning medication.

This is self-applied finger pressure only. Nothing on this page involves needles, heat sticks, cups or anything that breaks the skin.

What is LV13 traditionally used for?

• Abdominal fullness and bloating. As the Front-Mu point of the Spleen, LV13 was the classical first choice for distension, rumbling and a heavy feeling after eating. Human evidence specific to LV13 is essentially absent; studies that include it always combine it with several other points, so nothing can be credited to this point alone.
• Poor appetite and loose stools. Tradition frames these as weak Spleen function and uses LV13 to "harmonise" it. No controlled trial has tested finger pressure at LV13 for appetite or bowel habit, so this remains a traditional claim rather than a demonstrated effect.
• Stress-linked digestive upset. The pattern called "Liver overacting on the Spleen" describes gut symptoms that flare with frustration or pressure. Modern research does confirm that stress affects gut symptoms, but that does not validate the point; it validates the observation. Any relief you feel may come from slow breathing and a few quiet minutes.
• Flank and side discomfort. LV13 sits in the area people rub when their side feels tight, and gentle pressure there can feel pleasant. That is plausible local comfort from soft-tissue contact, not a channel-specific effect, and it should never be used to explain away side pain that keeps coming back.
• General relaxation. Holding a point and breathing out slowly reliably calms many people. This is a real and useful effect, but it is not unique to LV13 and would likely happen at many points on the body.

In short: the traditional reputation of LV13 is strong and the human evidence for it is thin. The most defensible thing to say is that it may be a pleasant, low-risk relaxation habit for some people with mild, already-diagnosed digestive discomfort. It is not a treatment for any condition, and persistent abdominal symptoms need a proper diagnosis rather than a pressure point.

Are there tips for using LV13 effectively?

• Breathe out as you press. Sink in on a slow exhale and hold while the belly softens. This makes the point easier to find and makes the whole technique more comfortable.
• Find the hollow, not the ridge. Your fingers should rest in the soft dip at the rib tip. If you feel a hard edge under the pad of your finger, slide a few millimetres until the tissue gives.
• Keep it light here. This is not a point for deep work. Over the lower ribs, less pressure held for longer beats hard pressure held briefly.
• Lie on your side for better access. Lying on the opposite side lets the ribcage drop and makes the floating rib tip much easier to identify than standing up.
• Warm your hands. Cold fingers on the waist make people tense and guard the area, which hides the landmark.
• Work both sides and compare. Noticing that one side is far more tender than the other is useful information — but if that difference is new, marked and persistent, mention it to a doctor rather than pressing it out.
• Give it a fair but limited trial. If you want to know whether it does anything for you, use it consistently for a week or two and note how you feel. If nothing changes, it is reasonable to stop.
• Combine it with the obvious things. Eating more slowly, smaller portions, less alcohol and a short walk after meals have far better evidence for bloating than any pressure point. Use LV13 alongside those, never instead.
• Keep your medication going. If you take something for reflux, bowel symptoms or a liver condition, do not reduce it because the point feels helpful. Changes to prescribed treatment are a conversation with your prescriber.

What do people get wrong with LV13?

• Pressing on bone. Landing on the hard rib shaft instead of the soft hollow at its free tip. It hurts, it does nothing useful, and it can leave the area sore for days.
• Counting to the wrong rib. The lowest free rib tip is GB25 on the 12th rib. LV13 is one rib higher, at the 11th. Many online videos show these two points interchangeably.
• Confusing it with LV14. LV14 sits much higher, below the nipple between the ribs at the front of the chest. It is a different point with different claims; LV13 is out at the side.
• Digging deep for a "release". People push hard because harder feels more serious. Over the lower ribs, with the spleen and liver underneath, hard pressure is the one genuinely risky thing a reader can do at this point.
• Expecting a cure. No pressure point cures a digestive disorder, a liver condition or chronic abdominal pain. Expecting that leads to disappointment and, worse, to delay in getting diagnosed.
• Using it on undiagnosed pain. Treating a new or worsening pain in your side with finger pressure is the wrong move. Pain in this area can come from the ribs, kidney, gallbladder, spleen or gut, and it needs a cause before it needs a technique.
• Ignoring tenderness that is new. Sudden marked tenderness on one side under the ribs, especially after an injury, is a reason to stop and get checked, not a sign the point is "working".
• Overdoing the frequency. Several minutes, many times a day, on the same patch of skin leads to soreness and bruising with no extra benefit.
• Reading tradition as proof. LV13 being a famous classical point tells you about its history, not about its measured effects in people today.

What does the research on LV13 actually say?

There is no useful human research on LV13 used on its own, and nothing at all on self-applied finger pressure at this point. That is the honest answer, and it is the same answer for most individual acupoints.

Where LV13 does turn up in the research literature, it appears as one ingredient in multi-point acupuncture protocols — typically studies of functional dyspepsia (indigestion with no structural cause), irritable bowel symptoms, or abdominal distension, where a practitioner needles a set of six or eight points chosen by traditional pattern. Even when such a trial reports a benefit, the design cannot tell you which point mattered, or whether any single point mattered. LV13 cannot be credited with the result.

It is worth saying clearly what those studies did: they used needles inserted by trained practitioners. That is a different intervention from pressing with a finger, and results from one do not transfer to the other. This page describes finger pressure only.

The wider acupressure evidence base has well-known limits. Most trials are small, often fewer than a hundred people. Participants usually know which group they are in, so expectation strongly colours self-reported outcomes like bloating, comfort and stress. Follow-up is usually short, often days or weeks. There is also a strong tendency for positive results to be published while null results are not.

The one genuine exception in the field is worth knowing, because it shows what decent evidence looks like: PC6 on the inner forearm has repeated controlled trials supporting a modest effect on nausea and vomiting. LV13 has nothing comparable.

What this means for you is simple. If LV13 feels pleasant and you use it gently as part of winding down, that is a reasonable low-risk habit. It should not displace medical assessment for digestive symptoms, and it should not be presented to you — by anyone — as a proven treatment.
