Liver 3 Point: Location, Functions, and How to Use It

Liver 3, known in traditional Chinese medicine as Taichong (LR3), is one of the most frequently used acupuncture and acupressure points in clinical practice. It sits on the top of the foot, in the depression between the first and second metatarsal bones, roughly two finger-widths back from the web between the big toe and second toe. Research has explored its effects on blood pressure, menstrual pain, anxiety, and brain activity, with several randomized trials showing measurable short-term results, particularly for blood pressure reduction and period-related discomfort.

Exactly Where to Find It

To locate LR3, start at the webbing between your big toe and second toe. Slide your finger slowly up the top of the foot, along the groove between the two long bones (metatarsals) that lead to those toes. About one and a half to two thumb-widths up from the web, your finger will settle into a noticeable dip or depression just before the bones meet. That depression is LR3. It often feels tender when you press into it, which practitioners consider a useful confirmation that you’ve found the right spot.

Anatomically, this location sits directly over the dorsal pedal artery, the pulse you can sometimes feel on the top of your foot. A dissection study of 40 feet found that this artery ran over the LR3 point in every single specimen. More relevant to why needling or pressing there produces effects, branches of the deep peroneal nerve distribute to the artery extremely close to LR3, with the average distance between the point and the nearest nerve branch being just a few millimeters.¹ That nerve-artery bundle likely explains why stimulation at this spot can influence the autonomic nervous system and produce effects well beyond the foot itself.

Blood Pressure Effects

The most studied clinical application of LR3 is blood pressure reduction, and the results are consistent enough to be worth a closer look. In a randomized controlled trial of patients with hypertension, acupressure at LR3 produced a meaningful drop in both systolic and diastolic blood pressure. Average systolic pressure fell from about 165 mmHg before treatment to roughly 143 mmHg thirty minutes afterward, with diastolic pressure dropping from around 96 to about 89 mmHg. The control group, which received no acupressure, showed no significant change.²

A separate randomized trial compared acupuncture at LR3 to sham acupuncture (needling at a non-acupoint) and found the real treatment significantly outperformed the sham in lowering both systolic and diastolic blood pressure. The reduction appeared within twenty minutes and persisted through a thirty-minute recovery period.³ These are acute effects measured in controlled settings, not evidence that pressing your foot replaces blood pressure medication. But they suggest a real physiological response, not just relaxation or placebo.

Part of that response appears to involve the autonomic nervous system. Laser stimulation of LR3 has been shown to shift heart rate variability measures in a direction consistent with reduced sympathetic (“fight or flight”) nervous system activity.⁴ In practical terms, stimulating this point seems to nudge the nervous system toward a calmer state, which would naturally bring blood pressure down.

Menstrual Pain and Cramping

LR3 is one of the points most commonly used for primary dysmenorrhea, the medical term for painful menstrual cramps that aren’t caused by an underlying condition like endometriosis. Several trials have tested it, usually in combination with Large Intestine 4 (LI4, located in the hand between the thumb and index finger), and the results have been positive enough to make this one of the better-supported acupressure applications.

A randomized controlled trial testing pressure on LR3 alone found it effective at reducing menstrual pain compared to a control group.⁵ Another randomized trial tested a simple protocol combining acupressure at both LR3 and LI4, and found that both pain intensity and duration improved significantly during the second and third menstrual cycles of the intervention period, along with quality of life improvements.⁶

The LR3-plus-LI4 combination is not arbitrary. In traditional Chinese medicine, these two points used together are called “Si Guan” or “Four Gates” (two points, each pressed bilaterally, making four stimulation sites). This pairing has been one of the most frequently applied point combinations across a range of conditions, including various digestive complaints, abdominal pain, and constipation.⁷ For menstrual cramps specifically, the combination seems to address both the cramping itself and the broader tension and stress that often accompany it.

Anxiety and Emotional Regulation

The claim that LR3 helps with stress and anxiety is common in acupressure guides, and there is some clinical evidence behind it, though the picture is mixed. In a trial of women with primary dysmenorrhea, acupressure at LR3 significantly reduced “apparent” (consciously felt) anxiety scores compared to baseline, while the control group’s scores did not change significantly. Hidden or subconscious anxiety, however, did not show significant improvement, and the between-group difference after treatment was not significant for either type.⁸

A broader scoping review of acupressure for depression, anxiety, and stress found that body acupoints like LR3 and Stomach 36 (ST36, located below the knee) were used to support overall emotional balance and physical well-being, though ear-based acupressure points played a larger role in stress management studies, making up the majority of applications in that category.⁹ So LR3 shows up in the anxiety-and-mood literature, but it’s typically part of a multi-point approach rather than a standalone solution.

What Brain Imaging Reveals

Some of the most interesting research on LR3 comes from functional MRI studies that track what happens in the brain during acupuncture at this point. These studies suggest the effects are not just local to the foot or even just autonomic. Stimulation at LR3 produces distinct patterns of brain activity that differ from stimulation at other commonly studied acupoints.

An fMRI study of 46 healthy subjects compared brain responses to acupuncture at three different points: LR3, LI4 (the hand point), and ST36 (the leg point). While all three produced overlapping deactivation in certain midline brain regions, each point also had its own signature. LR3 stimulation was most prominently associated with activity in the posterior hippocampus and posterior cingulate cortex, areas involved in memory processing and self-referential thought.¹⁰ LI4 dominated in the pregenual cingulate and hippocampal formation, while ST36 was strongest in the subgenual cingulate. Each point, in other words, talks to the brain differently, even when the surface-level experience of “deqi” (the sensation of aching or heaviness that signals an effective needle placement) feels similar.

A separate fMRI study looking specifically at LR3 found changes in functional connectivity between the temporal lobe and several other brain regions, including the superior frontal gyrus, the cingulate gyrus, and the insula. These changes were significantly different from sham acupuncture and from needling at a non-acupoint location.¹¹ The insula is particularly notable because it plays a central role in interoception (your sense of what’s happening inside your body) and emotional processing. Changes in insula connectivity could plausibly contribute to the calming and autonomic effects reported with LR3 stimulation.

How to Apply Acupressure at LR3 Yourself

You don’t need needles or a practitioner to use LR3. Acupressure, which uses sustained finger pressure instead of needles, is the most accessible way to work with this point at home. Here’s a practical approach:

Find the point: Sit comfortably with one foot resting on the opposite knee or on a surface where you can reach it. Slide your thumb from the web between your big toe and second toe up toward the ankle along the groove between the two metatarsal bones. Stop when your thumb drops into a natural depression, roughly two thumb-widths from the web.
Apply pressure: Use the pad of your thumb (not the tip or nail) to press firmly into the depression. The pressure should be strong enough to produce a deep, dull ache but not sharp pain. On a one-to-ten scale, aim for about a six or seven in pressure intensity.
Hold or massage: Maintain steady pressure for one to three minutes, or use small circular motions. Some practitioners recommend pressing during an exhale and slightly releasing during an inhale.
Work both feet: Since the meridian system is bilateral, most protocols press LR3 on both feet, one after the other or simultaneously if you can manage the position.

The blood pressure trials typically used about five minutes of sustained acupressure per session, with effects measured immediately afterward and up to thirty minutes later.² The dysmenorrhea trials used pressure for similar durations across multiple menstrual cycles.⁵ You don’t need to time it precisely, but spending less than a minute is probably not enough to produce the kind of autonomic shift the research describes.

The Four Gates Combination

If you’ve spent any time reading about acupressure, you’ve likely come across the recommendation to press LR3 and LI4 together. LI4 sits in the fleshy web between your thumb and index finger, and pairing it with LR3 creates what practitioners call the Four Gates (pressing both points on both sides of the body). This combination appears frequently in both classical texts and modern clinical practice for conditions spanning pain, digestive complaints, and emotional disturbance.⁷

The neuroimaging data offers a plausible reason why combining these points might work differently than using either alone. LR3 and LI4 activate partially overlapping but also distinctly different brain regions.¹⁰ LI4 is more associated with the pregenual cingulate and hippocampal formation, while LR3 has its strongest effects in the posterior cingulate and posterior hippocampus. Using both together may engage a broader swath of the brain’s pain-modulating and emotion-regulating networks than either point alone. This isn’t conclusively proven, but it aligns with what practitioners have observed clinically for centuries and with the trial data showing the combination is effective for menstrual pain.⁶

One important caution: LI4 is traditionally contraindicated during pregnancy because of concerns that strong stimulation there could promote uterine contractions. The evidence behind this warning is debated, but most practitioners err on the side of caution and avoid heavy pressure on LI4 in pregnant women. LR3 alone does not carry the same caution in most traditions, though if you are pregnant and considering acupressure for any purpose, talking to a qualified practitioner first is a reasonable step.

LR3 in Liver and Digestive Conditions

Given that this point sits on the Liver meridian, it’s natural to wonder whether it has any connection to actual liver health. The name “Liver 3” refers to the traditional Chinese medicine meridian pathway, not to the organ in the way Western medicine would frame it. That said, there is a curious overlap. A systematic review and meta-analysis of acupuncture for non-alcoholic fatty liver disease (NAFLD) found that LR3 was one of the most commonly selected acupoints across randomized controlled trials, appearing in seven out of the eight included studies. The other most-used point was ST36, also included in seven trials.¹²

This doesn’t mean pressing your foot cures fatty liver disease. The NAFLD trials used professional acupuncture with needles, often alongside other treatments, and the evidence base is still small. But LR3’s consistent selection across these studies suggests that experienced practitioners consider it relevant to liver-associated metabolic conditions, not just pain and mood. The traditional Chinese medicine framework treats the Liver meridian as governing the smooth flow of qi throughout the body, which encompasses digestive function, emotional fluidity, and musculoskeletal flexibility. Western research on LR3 keeps turning up effects in autonomic regulation, brain connectivity, and vascular tone that, while described in completely different language, overlap with those traditional claims in interesting ways.

What the Point Won’t Do

It’s worth being realistic about limits. The blood pressure reductions measured in trials are acute, meaning they were captured in the minutes after stimulation. No study has demonstrated that self-acupressure at LR3 produces lasting blood pressure control comparable to medication. If you have hypertension, this might be a useful complement to your treatment plan but not a substitute for it.

Similarly, the anxiety findings are modest. The within-group improvement in one trial was real, but the between-group difference was not significant, meaning acupressure at LR3 may reduce anxiety relative to your own baseline without clearly outperforming what happens when you simply sit still for the same amount of time.⁸ Some of the benefit could be from the act of stopping, sitting, and paying attention to your body. That’s not a dismissal; relaxation and body awareness have real value. But it’s a different claim than “this specific point uniquely fixes anxiety.”

The menstrual pain evidence is the strongest for self-care application, with multiple trials showing significant improvements in pain intensity and duration that beat control conditions. If you experience monthly cramps and want to try something low-risk alongside your usual approach, working LR3 (and ideally LR3 plus LI4 together) across two or three cycles is the most evidence-supported use case for at-home acupressure at this point.

Why You Sometimes Feel Tenderness Without Pressing Hard

Many people notice that LR3 is sore even with light pressure, especially during periods of stress, menstrual discomfort, or headaches. In traditional Chinese medicine, tenderness at an acupoint is interpreted as a sign of stagnation or imbalance in the associated meridian. From a Western anatomy perspective, the LR3 region sits over a neurovascular bundle where nerve branches reach the dorsal pedal artery within just a few millimeters of the point.¹ Areas where nerves and blood vessels bundle together tend to be more sensitive than surrounding tissue, which may explain why this particular spot on the foot feels different from the tissue just a centimeter away. The tenderness some people report during stress or illness may reflect changes in local blood flow, nerve sensitivity, or muscle tension in the foot that track with systemic autonomic activation. Pressing a spot that already has heightened nerve activity could amplify the signaling that reaches the brain, which might partly explain why acupressure there produces measurable central nervous system effects even though the stimulation is occurring far from the organs and brain regions it seems to influence.
