What is SP5?

SP5 (Shangqiu) is a classical Spleen-channel point in the hollow just in front of and below the inner ankle bone.

In Chinese medicine SP5 is the fifth point of the Spleen channel and one of its Five Shu points, classed as the Jing-River and Metal point. Older texts also call it a point for draining excess from the Spleen channel.

Tradition links SP5 to digestion and to the ankle itself. Classical indications include abdominal bloating, rumbling, loose stools, constipation, heaviness in the limbs, and pain or stiffness in the inner ankle and foot.

Here is the honest verdict on the evidence: there are no good controlled human trials testing SP5 on its own for any of these complaints. Where SP5 appears in research it is usually one of several points in a mixed protocol, which makes it impossible to say what SP5 itself did.

Two things are worth stating plainly once, and they apply to every section below. First, a long traditional history is not evidence that a point works; it tells you what practitioners believed, not what has been measured. Second, that same history is not evidence that pressing a point is safe for you, because the people who wrote those texts were not thinking about your blood thinners, your recent ankle surgery or your diabetic foot.

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

What acupressure on SP5 may reasonably offer is what gentle, attentive pressure on a tender foot usually offers: a few minutes of comfort, some local easing of stiffness, and a calm pause. That is a modest and real thing. It is not a treatment for a digestive disease, and it should never replace a diagnosis for gut symptoms that are new, severe or persistent.

Where is SP5 and how do you find it?

SP5 sits in the soft dip between the tip of your inner ankle bone and the bony bump further forward on the inside of your foot.

• Sit down and cross one ankle. Rest the foot on the opposite thigh so the inner side of the ankle faces you. Good light helps, because this point is found by feel more than by sight.
• Find your inner ankle bone. This is the medial malleolus, the round knob on the inside of the ankle. Put a fingertip on its lowest, most forward tip.
• Find the second bump. Slide your finger forward along the inside edge of the foot, towards the big toe, about two to three centimetres. You will meet another bony rise, the navicular tuberosity.
• Press into the hollow between them. SP5 is in the soft depression between those two bony points, roughly midway. The spot is usually a little tender and feels slightly spongy compared with the bone either side.
• Check you are not on bone. If your finger is on something hard and unyielding, you have drifted onto the ankle bone or the navicular. Walk your fingertip back and forth until it drops into the dip.

In traditional measurements SP5 is described as being in the depression distal and inferior to the medial malleolus. Distal and inferior simply mean forward of it and below it, on the inner edge of the foot.

A common landmark mix-up is worth flagging. SP6 is a different point, three thumb-widths above the top of the inner ankle bone on the back edge of the shin bone. KI3 is behind the ankle bone, in the groove between it and the Achilles tendon. SP5 is neither of those; it is forward and low, almost on the instep.

How do you apply pressure to SP5?

1. Get comfortable first. Sit with the foot resting on the opposite thigh or on a low stool. Do not bend awkwardly to reach it, since straining your back defeats the purpose.
2. Settle your thumb in the hollow. Use the pad of the thumb, not the nail. Let the fingers of the same hand wrap the outer side of the foot so you have something to press against.
3. Press in slowly. Build up over two or three seconds until you feel a firm, dull ache. A score of about 3 or 4 out of 10 is right. Sharp, bright or burning pain means ease off immediately.
4. Hold or circle. Either hold steady pressure for 20 to 30 seconds, or make small slow circles for the same time. Keep breathing normally.
5. Release and repeat. Let go for 10 seconds, then repeat three to five times. One side takes two to three minutes.
6. Do the other foot. Points are used on both sides unless only one ankle is stiff. Most people find the two sides feel noticeably different.
7. Repeat sensibly. Once or twice a day is plenty. There is no benefit to grinding at the spot for ten minutes.

Stop straight away if the skin reddens and stays red, if the ache keeps getting worse rather than settling, if you feel pins and needles spreading into the foot, or if you feel faint or light-headed.

Do not work on SP5 through a sock seam or a shoe edge, and do not use a hard tool, a pen cap or a massage stick here. The area sits over tendons and the back of the foot's arch, and a hard point can bruise skin that has very little padding.

Nothing about this involves needles, heat or anything that breaks the skin. If you have numb feet and cannot feel pressure accurately, do not use this point unsupervised.

What is SP5 traditionally used for?

• Bloating and abdominal fullness. Classical texts list SP5 for distension and rumbling in the belly. There are no controlled human trials of SP5 alone for bloating, so this remains a traditional claim rather than a measured effect.
• Loose stools or constipation. Tradition frames SP5 as regulating the Spleen's handling of fluids, and uses it for both ends of bowel trouble. Human evidence specific to this point is absent; studies on acupuncture for bowel symptoms use multi-point protocols, so SP5's own contribution is unknown.
• Inner ankle pain and stiffness. This is the most plausible use, because SP5 lies directly over the sore area in many ankle complaints. Gentle local pressure and movement can ease stiffness, but no trial has tested SP5 specifically against a sham for ankle pain.
• Heaviness and sluggishness in the legs. Described traditionally as clearing dampness. In modern terms this is a feeling, not a diagnosis, and nothing has been measured. Some people simply find foot pressure relaxing.
• General relaxation. A few quiet minutes of deliberate foot pressure lowers tension for many people. This is a non-specific effect of touch and attention, not a property unique to SP5.
• Classical oddities. Old texts also name SP5 for jaundice, a stiff tongue and childhood convulsions. These are historical indications with no modern support, and all three describe conditions that need urgent medical assessment today.

The wider picture is that acupressure research as a whole is made up of small, short-term, unblinded studies. Blinding is genuinely hard, because a person can tell they are being pressed. That weakens even the positive findings.

One contrast is useful. PC6 at the wrist has repeated controlled trials supporting it for nausea and vomiting, and that is the clearest case in the whole acupressure literature. SP5 has nothing of that quality behind it, and saying otherwise would be dishonest.

Are there tips for using SP5 effectively?

• Warm the foot first. A minute of rubbing, or pressing after a warm shower, makes the hollow easier to find and the pressure more comfortable. Cold, tense feet feel bony and vague.
• Let tenderness guide you. SP5 is usually slightly tender compared with the bone on either side. If you have hunted for a minute and found nothing tender, you are probably still on the ankle bone.
• Use the hand on the same side. Reaching across the body twists your spine. Crossing the ankle onto the opposite thigh and using the nearer hand is steadier and lets you feel more.
• Pair it with ankle movement. For stiffness, hold the pressure while slowly circling the foot. Movement plus pressure usually loosens an ankle more than either alone.
• Keep sessions short and regular. Two or three minutes a side, once or twice a day, beats one long session. Long grinding pressure mostly produces soreness.
• Trim your thumbnail. There is very little padding on the inside of the foot. A long nail digs in and can scratch skin before you notice.
• Track honestly. If you are using SP5 for bloating or an ache, note the symptom score before and after for a fortnight. Honest notes tell you quickly whether it is doing anything for you personally.
• Treat it as an add-on. Use it alongside, not instead of, the things with stronger support for digestion and ankle recovery: fluids, fibre, sleep, graded walking and any treatment your doctor or physiotherapist has given you.
• Stop if it hurts afterwards. Pressure that leaves the inner ankle sore for hours is too hard. Halve it next time, or leave the point alone for a few days.

One practical note on expectations. Any easing you feel from SP5 is likely to be short-lived and modest. That is still worth something, but judge it on that scale rather than hoping for a transformation.

What do people get wrong with SP5?

• Pressing on bone. Landing on the hard ankle bone instead of the soft hollow in front of and below it. Bone gives no spongy feel and no useful tenderness, and prolonged pressure there just bruises.
• Confusing SP5 with SP6. SP6 is three thumb-widths above the top of the inner ankle bone, on the back edge of the shin. SP5 is low and forward, on the instep. Many videos muddle the two.
• Confusing SP5 with KI3. KI3 sits behind the ankle bone, in the groove in front of the Achilles tendon. If your thumb is behind the ankle knob, you are not on SP5.
• Expecting a cure. No acupressure point cures a digestive condition or a damaged ankle. Pressing SP5 and waiting for a problem to disappear wastes time that a diagnosis might use better.
• Working a freshly sprained ankle. People press hard into a hot, swollen ankle hoping to speed healing. Pressure on an acutely injured, swollen or possibly fractured ankle can make things worse and delay proper assessment.
• Using a hard tool. Pen caps, knuckles and pointed massage sticks concentrate force onto thin skin over tendon. Fingers give better feedback and far less bruising.
• Going too hard for too long. More pressure is not more effect. Beyond a dull ache you are just creating soreness and, on blood thinners, possibly a bruise.
• Dropping real treatment. Stopping a prescribed medicine, a rehab programme or a planned investigation because the point feels helpful is the most costly mistake on this list.
• Ignoring numb feet. If reduced sensation means you cannot judge how hard you are pressing, you can injure skin without feeling it. That applies strongly to long-standing diabetes.

What does the research on SP5 actually say?

There is essentially nothing specific. We found no controlled human trial that tested SP5 on its own, by acupressure or by any other method, for digestion, bowel symptoms or ankle pain. That is the plain answer, and it is the answer for most individual acupuncture points.

Where SP5 does turn up in published work, it is as one name on a list. Acupuncture studies for functional bowel complaints and for ankle sprain typically needle several points in one session. When a mixed protocol shows a benefit, the result belongs to the whole package, not to any single point in it. You cannot extract an SP5 effect from that design.

A second gap matters too. Most research on this channel involves needling, not finger pressure. Reporting that a trial needled a point is just describing what the researchers did; it tells you little about what a thumb on intact skin will achieve, and this page never instructs needling.

The broader acupressure literature has the same weaknesses throughout. Trials tend to be small, run for days or weeks rather than months, and are rarely blinded, because a participant can feel where they are being pressed. Comparison groups often receive no treatment at all, which inflates the apparent benefit. Positive results from that kind of study are a hint to test further, not a finding to rely on.

For contrast, PC6 at the wrist has been tested repeatedly in controlled trials for nausea and vomiting, including in pregnancy and after surgery, and the evidence there is genuinely reasonable. That comparison shows what decent point-specific evidence looks like. SP5 does not have it.

What this means for you is straightforward. Use SP5 as a low-risk comfort measure if you enjoy it, judge it by your own experience over a couple of weeks, and do not let it stand in for the assessment of a symptom that is new, worsening or persistent.
