Qichong

What is ST30?

ST30 (Qichong) is a Stomach-channel point in the groin crease, level with the top of the pubic bone and about two thumb-widths off the midline.

Its Pinyin name, Qichong, is usually translated as "Surging Qi" or "Penetrating Qi". In classical Chinese medicine it is described as a meeting place of the Stomach channel and the Chong Mai, the so-called Penetrating Vessel, and as one of the points of the "Sea of Qi" in the lower abdomen. On that basis it was used for complaints of the lower belly, the groin and the reproductive organs.

That is a long and well-documented traditional pedigree. It is worth saying once, clearly, that traditional standing is not evidence that a point works, and it is also not evidence that a point is safe. Those are two separate questions, and this page keeps them separate.

The honest verdict on the evidence: there is essentially no human research that tests ST30 on its own for any condition. Acupressure research overall is dominated by small, short, unblinded studies, and ST30 has not been a focus even within that modest literature. So anything you read about what Qichong "does" is tradition and practitioner experience, not trial data.

Everything described here is self-applied finger pressure on unbroken skin. This page never describes needling, moxibustion or cupping, and you should not attempt any of those on yourself. Where a published trial used needles, that is reported as what the researchers did, not as something for you to copy.

ST30 also sits in a crowded piece of anatomy. The femoral artery, the inguinal lymph nodes and the inguinal canal are all nearby. That makes the "who should avoid it" section unusually important for this point, more so than for a point on the hand or the shin. Read it before you press.

Where is ST30 and how do you find it?

ST30 sits at the level of the upper edge of the pubic bone, about two thumb-widths (roughly 5 cm) out from the midline, at or just above the groin crease.

• Lie down first. Lie on your back with your knees bent and feet flat. This softens the lower belly and makes the bony landmarks easier to feel.
• Find the top of the pubic bone. Walk your fingers down the midline of your lower belly until you meet a firm horizontal ridge of bone just above the pubic hair line. That upper edge is your height reference.
• Move sideways two thumb-widths. From the midline at that level, measure about two of your own thumb-widths out to the side. In classical terms this is 2 cun lateral to the midline; in most adults it is around 4 to 6 cm.
• Settle into the soft hollow. You should be in soft tissue at the top of the groin crease, not on hard bone and not out on the hip. If you are on the pubic bone itself, you have come in too far toward the midline.
• Feel for the pulse and move off it. A little below and lateral to this area you may feel the femoral artery pulsing in the groin. ST30 is described as lying medial to that pulse. If your finger is on a beating vessel, shift slightly toward the midline until the beat is gone.

Two common mix-ups are worth naming. The bony knob you can feel on the front of your hip, well out to the side, is the hip bone, not ST30 — that is far too lateral. Points higher up the same line sit above the pubic bone, closer to the navel, so if your finger is nearer your belly button than your pubic bone you have drifted up the channel.

Because the point lies in the groin, it is easiest to locate on yourself, in private, with the waistband lowered rather than through clothing.

How do you apply pressure to ST30?

1. Empty your bladder first. ST30 sits over the lower abdomen, and pressing with a full bladder is uncomfortable and unhelpful.
2. Lie on your back, knees bent. This relaxes the abdominal wall so you are not fighting tense muscle.
3. Check for a pulse. Rest two fingers lightly on the spot for a few seconds. If you feel a steady beat under your fingertips, move slightly toward the midline before pressing. Never bear down on a pulsing vessel.
4. Use the flat pads of two fingers. Index and middle finger together, pads flat, nails away from the skin. Do not dig in with a single fingertip or a knuckle.
5. Press gently and slowly. Sink in over about three seconds to a pressure you would rate 2 or 3 out of 10. The groin is sensitive, and more pressure is not better here.
6. Hold for 30 to 60 seconds. Breathe slowly out through the mouth while you hold. You can also use small, slow circles instead of a static hold.
7. Release slowly, then repeat. Let the pressure off over a couple of seconds. Two or three rounds per side is plenty.
8. Do both sides. ST30 is a paired point, one on each side of the midline.
9. Limit how often. Once or twice a day is reasonable. There is no benefit in grinding at it for long stretches.

Stop immediately and do not continue if you feel sharp or shooting pain, numbness or tingling down the leg, a lump or pulsing mass under your fingers, or any bulge that appears when you cough or strain. Those are signs to leave the area alone and get it checked.

Also stop if the skin is reddening, bruising or sore afterwards. Light bruising in this soft area means you pressed far harder than the technique calls for. Give it several days before trying again, and use less force.

What is ST30 traditionally used for?

• Lower abdominal and groin discomfort. The classical texts place ST30 among the points for pain, fullness and dragging sensations low in the belly and groin. Human evidence testing ST30 for this is absent, so treat it as a traditional indication only.
• Menstrual complaints. Because of its link to the Chong Mai, the vessel tradition associates with menstruation and fertility, Qichong appears in older point lists for irregular or painful periods. Trials of acupressure for period pain exist, but they use other points, most often SP6 and LI4, and their results are mixed and come from small, unblinded studies.
• Reproductive and sexual complaints. Traditional sources list ST30 for impotence, swelling or pain of the genitals, and infertility. There is no controlled human research isolating this point for any of these, and none of them should be self-managed with pressure instead of a medical assessment.
• "Qi rushing upward". The name Qichong refers to a classical idea of energy surging up the midline, described in old texts as a rising, panicky sensation from the lower belly to the chest. This is a traditional description of a symptom, not a diagnosis recognised in modern medicine.
• Bloating and digestive fullness. As a Stomach-channel point on the abdomen, ST30 appears in traditional protocols for distension. Any relief most people notice from slow abdominal pressure with slow breathing is hard to separate from relaxation itself.
• Hernia-type groin pain. Old sources mention ST30 for "shan" disorders, a broad classical category that includes groin swellings and hernias. This is one to be careful with: a genuine hernia is a structural problem, pressing on it can hurt you, and it needs a doctor rather than a pressure point.

Across the board, the pattern is the same. ST30 has a long traditional record and almost no modern evidence. Gentle pressure here is low-risk for most healthy adults, but it is not a treatment for any of the conditions listed above.

Are there tips for using ST30 effectively?

• Warm your hands first. Cold fingers on the lower belly make the abdominal muscles tense and guard, which hides the soft hollow you are aiming for. Rub your palms together for a few seconds before you start.
• Let your breath do half the work. Press as you breathe out, ease off as you breathe in. Slow exhaling relaxes the abdominal wall and makes a light pressure feel like it is reaching further.
• Flat contact, not a point. The pads of two fingers spread the load. A single fingertip or thumbnail concentrates it and is far more likely to bruise this soft area.
• Wait an hour after a big meal. Pressing on a full lower abdomen is uncomfortable and may make bloating feel worse, not better.
• Keep a short record. Note the date, how long you pressed and what you noticed over the next hour. A week of honest notes tells you more than any article about whether it does anything for you.
• Stay symmetrical. Work both sides for the same length of time. If one side is markedly more tender than the other and stays that way, that is worth mentioning to a doctor rather than pressing harder.
• Pair it with the basics. For ordinary lower-belly ache or period discomfort, a heat pack, movement and sleep have better support than any single pressure point. Use ST30 alongside those, not in place of them.
• Give it a fair but finite trial. If a week or two of regular, gentle use changes nothing, accept that answer. Escalating pressure on the groin to force a result is how people hurt themselves.
• Do it somewhere private. This point sits at the top of the groin crease. You need skin contact and a relaxed posture, which is not a public-transport activity.

What do people get wrong with ST30?

• Expecting a cure. The single biggest error. No acupressure point cures infertility, erectile problems, hernias or period pain, and ST30 has no trial evidence behind any such claim. Expecting a cure also delays care that might actually help.
• Pressing on the pulse. The femoral artery runs through this region. If you feel a beat under your fingers, you are on a blood vessel. Move toward the midline or stop. Never lean your body weight onto a pulsing spot.
• Pressing a lump or a bulge. A swelling in the groin that comes and goes, or appears when you cough, needs a doctor. Massaging it is not a treatment and can make things worse.
• Going too deep. People treat the abdomen like a tight shoulder and dig in. This area has little padding over important structures, and hard pressure buys you bruising, not benefit.
• Landing on the hip bone. Measuring too far out lands you on the bony prominence at the front of the hip. ST30 is in soft tissue roughly two thumb-widths from the midline, not out at the side.
• Drifting up toward the navel. Other Stomach-channel points sit higher on the same vertical line. ST30 is level with the top edge of the pubic bone, close to the groin crease.
• Using it during pregnancy. Lower-abdominal points are routinely avoided in pregnancy, and ST30 sits directly over the lower belly. This is not the point to experiment with.
• Trying to copy a needling video. Clips that show needles, angles or depths are showing clinical acupuncture. Nothing on this page involves needles, and you should not attempt needling, moxibustion or cupping on yourself.
• Ignoring new pain. Tenderness that is new, one-sided and persistent is information, not an obstacle. Stop pressing and get it looked at.

What does the research on ST30 actually say?

There is essentially nothing. We could not identify any controlled human trial that tests ST30 (Qichong) on its own, by acupressure or by any other method, for any condition. That is the honest answer, and it is the usual answer for most individual acupuncture points.

Where ST30 does appear in the research literature, it is as one point inside a larger protocol. Acupuncture studies in areas such as pelvic pain, menstrual disorders and male reproductive complaints often needle six, eight or more points in a single session. Those trials were needling studies, not acupressure, and that is reported here only to describe what the researchers did. Even when such a study shows a benefit, its design cannot tell you which point contributed, or whether finger pressure on one of them would do anything at all.

The wider acupressure evidence base is worth understanding, because it sets the ceiling for what any point page can honestly claim. Most trials are small, run for a few weeks, and cannot blind participants to whether they are being pressed. Expectation and attention both shift self-reported symptoms, so unblinded results drift upward. The clearest exception in the whole field is PC6 on the forearm for nausea and vomiting, where repeated controlled trials and systematic reviews support a real, modest effect. ST30 has nothing comparable.

What that absence means in practice is simple. It does not prove ST30 is useless, and it does not prove it is useful. It means nobody has done the work. If gentle pressure here feels pleasant and you use it as part of a relaxation routine, that is a reasonable, low-cost thing to do. Treating it as therapy for a diagnosed condition is not supported.

If you see a page or a video citing a specific trial on Qichong with a journal name and a number, check the citation itself. Fabricated references are common in this corner of the internet, and we would rather tell you the shelf is empty than fill it.
