What is ST41?

ST41, or Jiexi, is a classical Stomach-channel point in the hollow at the front of the ankle, between the two main tendons.

The name is usually translated as "Ravine Divide", which describes the dip you can feel there. In classical theory ST41 is the Jing-River point of the Stomach channel and its Fire point, which also makes it the channel's traditional tonification point. That gives it a high profile, and most acupuncture curricula teach it.

Tradition uses ST41 for ankle pain and swelling, a foot that drags or feels weak, headache with dizziness, puffiness around the face and eyes, and bloating or constipation. Those are claims drawn from a system of theory, not findings from a laboratory.

Here is the honest verdict. There is essentially no published human research that tests ST41 on its own for any of those uses. It turns up inside multi-point acupuncture formulas in stroke and ankle studies, but a formula cannot tell you what one point contributed. Long standing in tradition is not evidence that a point works, and it is not evidence that pressing it is safe for you.

What that means in practice: treat ST41 as a comfort measure rather than a treatment. Some people find steady pressure on a stiff ankle pleasant and relaxing, and that is a reasonable reason to try it. It is not a reason to delay care for an injury, a swollen leg or a persistent headache.

Everything described on this page is self-applied finger pressure. Nothing here involves needles, heat or any technique that breaks the skin.

Where is ST41 and how do you find it?

ST41 sits in the hollow at the middle of the front ankle crease, between the two big tendons that stand up when you pull your toes toward you.

• Sit so you can reach your ankle. Rest the foot on the opposite knee, or sit on the floor with the knee bent. You need the front of the ankle relaxed and visible.
• Find the ankle crease. Pull your toes up toward your shin. A crease appears across the front of the ankle, roughly level with the line between the bony bump on the inside and the one on the outside.
• Make the tendons pop. With the toes still lifted, two cords stand out on the front of the ankle. The inner one moves when you lift only your big toe; the outer one moves when you lift the other four toes.
• Drop into the gap. ST41 is in the soft hollow between those two cords, right at the crease. Line it up loosely with the space between your second and third toes.
• Check by feel. Relax the foot and press gently. You should sink into a dip, not onto hard bone or a tight cord. The spot is often mildly tender.
• Move off any pulse. An artery runs through this region. If you feel a throb under your fingertip, lift off and reposition slightly to the side rather than pressing down on it.

Some texts describe ST41 as roughly level with the tip of the outer ankle bone. Use the crease and the tendon gap as your main guide, since those are easy to feel on yourself. If you are unsure, stay with the obvious hollow at the centre of the crease rather than hunting for a precise spot.

Do not confuse ST41 with points further forward on the top of the foot. ST41 is at the ankle itself, where the leg meets the foot.

How do you apply pressure to ST41?

1. Settle the foot. Sit down and support the ankle so the lower leg is not holding itself up. A tense leg makes the hollow harder to find and the pressure less comfortable.
2. Place your thumb or finger pad. Use the flat pad of a thumb or index finger, not a nail or a knuckle. Set it in the hollow between the two tendons at the ankle crease.
3. Press straight down, gently. Sink in slowly toward the ankle joint. Aim for firm but comfortable, around three to five out of ten. You want a dull ache, never a sharp or burning feeling.
4. Hold or circle. Keep steady pressure for 30 to 60 seconds, or make small slow circles without sliding over the skin. Breathe normally and keep your shoulder relaxed.
5. Repeat and swap sides. Do two or three rounds on one ankle, then the same on the other. Most people use both sides, since the point exists on each leg.
6. Keep it short and regular. Two or three short sessions a day is plenty. Longer or harder is not better and only raises the chance of bruising.
7. Stop at these signals. Lift off immediately for sharp pain, pins and needles, numbness spreading into the foot, a throbbing pulse under your finger, or skin that stays red and sore afterwards.

Warmth helps. A few minutes of ankle circles, a warm shower or a wrapped heat pack before you start makes the area more comfortable to work on.

Keep your nails short and your skin clean. Finger pressure only: no needles, no heat applied to the skin, no suction, nothing that breaks the skin. If you are pressing hard enough to leave a mark, you are pressing too hard.

What is ST41 traditionally used for?

• Ankle pain and stiffness. This is the oldest and most consistent claim, and it is the one that makes anatomical sense, since the point sits right on the front of the ankle joint. Human evidence for pressure on ST41 specifically is absent. Gentle pressure around a stiff, uninjured ankle may feel good, which is a fair reason to try it.
• A weak or dragging foot. Classical texts link ST41 to foot drop, where the toes catch when walking. It appears in acupuncture point selections used in stroke rehabilitation research, but those studies needle several points at once and cannot show what ST41 added. Finger pressure is not a substitute for physiotherapy or a proper gait assessment.
• Headache with dizziness. Tradition treats ST41 as a distal point for head symptoms along the Stomach channel, especially frontal headache. There are no trials testing it for this. Acupressure for headache in general rests on small, unblinded, short-term studies.
• Bloating and constipation. Because it belongs to the Stomach channel, ST41 is grouped with digestive complaints in classical sources. No human research supports pressing it for these. Useful contrast: PC6 and nausea does have real controlled trial support, and ST41 has nothing of that kind.
• Puffiness of the face and red eyes. An older classical indication rather than a modern one. Nothing in the research literature speaks to it, and facial swelling that is new or one-sided needs a doctor, not a pressure point.
• Restlessness and agitation. Some texts list mental restlessness among its uses. Any calming effect from a quiet minute of self-massage is plausible but non-specific, and the same could be said of rubbing almost anywhere.

In short: ST41 is well established inside the tradition and almost untested outside it. Use it as a comfort routine, and keep real treatment for the underlying problem.

Are there tips for using ST41 effectively?

• Lift the toes to find it, relax them to press it. Dorsiflexing makes the tendons stand out so you can locate the gap. Once your finger is in place, let the foot go soft so you are not pressing into a tight cord.
• Warm the ankle first. A warm shower, a wrapped heat pack or a minute of slow ankle circles makes the tissue more comfortable and the point easier to feel.
• Map before you press. Skim the whole crease with light fingertip pressure and note the dip and the tender spot. Finding it this way beats guessing and then leaning in hard.
• Match pressure to tenderness. If a spot is sore, back off rather than pushing through. The goal is a dull, tolerable ache that fades as you hold.
• Work both ankles. Doing one side and then the other takes two minutes and feels more balanced than fixating on a single foot.
• Pair it with movement. For a stiff ankle, follow the pressure with slow ankle circles, calf stretches and a short walk. Movement is the part with actual evidence behind it for joint stiffness.
• Keep sessions short and frequent. A minute or two a few times a day is more sustainable, and kinder to the skin, than one long grinding session.
• Keep a simple note. Jot down pain or stiffness out of ten before and after, for a week or two. It tells you honestly whether this is worth your time, which no article can.
• Check your footwear too. Front-of-ankle discomfort is often aggravated by tight laces over the ankle crease. Loosening the top eyelets may do more than any amount of pressing.

If you cannot reach your ankle comfortably, or balance makes it awkward, skip ST41 entirely. Nothing about this point is essential, and straining to reach it is not worth a fall.

What do people get wrong with ST41?

• Expecting a cure. ST41 will not fix a damaged ankle, reverse foot drop or clear chronic constipation. Going in with that hope leads to too much pressure, too often, and disappointment.
• Pressing on tendon or bone. Landing on one of the standing cords, or on the hard bone beside the hollow, is the most common location error. Ease sideways until your finger sinks into the dip.
• Leaning on a pulse. An artery passes through this area. If you feel a throb, shift your finger slightly rather than pressing harder to "get deeper".
• Working on a fresh injury. A newly sprained, swollen or hot ankle needs assessment, rest and possibly an X-ray. Pressure on an undiagnosed fracture or torn ligament can make things worse.
• Going too hard. Skin over the front of the ankle is thin. Digging with a nail or knuckle leaves soreness and bruising, and bruising is not a sign that it worked.
• Using it instead of rehab. For a weak or unstable ankle, the things that change outcomes are strengthening, balance work and proper footwear. Pressure is at best an add-on.
• Mixing it up with nearby points. ST41 is at the ankle crease, not on the top of the foot or between the toes. If you are in the middle of the foot, you have gone too far forward.
• Ignoring one-sided swelling. A single calf or ankle that is swollen, warm and painful can mean a blood clot. Massaging it is the wrong move; get it checked the same day.
• Abandoning it after one try, or never stopping. Give it a fair trial of a week or two with notes, then decide. Drifting into daily hard pressure on a point that is doing nothing for you helps no one.

What does the research on ST41 actually say?

There is no body of human research testing ST41 on its own, by needle or by finger pressure, for any condition. That is the plain answer, and it has not changed with more searching.

Where ST41 does appear in published trials, it is one item in a longer point prescription. Acupuncture studies in stroke rehabilitation and in ankle and foot complaints sometimes include it alongside several other points chosen by a practitioner. Those designs can only tell you about the whole package. They cannot show what ST41 contributed, or whether removing it would have changed anything.

The wider acupressure literature has the same weaknesses almost everywhere. Studies tend to be small, run for a short time, and are rarely blinded, because people usually know whether someone is pressing on them. Outcomes are often self-reported pain or comfort scores collected right after the session. That mix makes placebo and expectation effects hard to separate from any real effect.

For contrast, it helps to know what good evidence looks like in this field. Pressure or wristbands at PC6 for nausea and vomiting has been tested in many controlled human trials, and there is reasonable support for a modest effect. ST41 has nothing remotely comparable, and no one should present it as if it does.

So the evidence grade here is "insufficient", while the traditional tier is high: ST41 is taught on every curriculum and listed in the classical sources. Those are two separate things. A reader deciding whether to spend two minutes a day on this point should understand they are trying a traditional comfort practice, not a treatment with measured results behind it.
