What Are Acupuncture Points? The 7 Most Useful Points for Self-Acupressure

Points on a Map That Most People Cannot See

Acupuncture points (穴位, xué wèi) are specific locations on the body's surface where the qi flowing through the meridian channels is said to be most accessible — where it can be stimulated, regulated, or redirected by needles, pressure, moxa, or cupping to produce effects throughout the meridian's pathway and associated organ system.

The concept requires accepting at least provisionally that the meridian system is real as a functional concept — that there are pathways through which the body's energy flows, and that specific points on these pathways have specific effects when stimulated. The scientific status of meridians remains contested; the clinical reality of acupuncture points as sites of therapeutic effect is supported by substantial evidence across dozens of randomised controlled trials.

Understanding the basic logic of acupuncture points — even without needles — is practical knowledge. The most commonly used points can be stimulated through acupressure (firm finger pressure) and are relevant to the most common everyday complaints: headache, fatigue, poor sleep, digestive discomfort, and eye strain.

How Points Are Organised

The 361 classical acupuncture points are distributed along 14 primary meridians — 12 organ meridians (one for each of the six yin and six yang organs in TCM) plus the governing vessel (督脉, dū mài) and conception vessel (任脉, rèn mài) that run along the midline of the back and front of the body respectively.

Each point has:

• A number within its meridian (e.g., Stomach 36, abbreviated ST36)
• A Chinese name that describes its location or function (e.g., 足三里, zú sān lǐ — "Leg Three Miles")
• A specific location defined by landmarks and cun (寸, a body-proportional measurement unit based on the width of the patient's thumb)
• A set of primary actions and indications
• Contraindications where applicable (some points are avoided during pregnancy; some require practitioner skill for safe needling)

The meridian organisation means that a point's location does not have to be near the area it treats. ST36, one of the most important points for digestive function, is on the lower leg — not on the abdomen. The therapeutic effect travels through the meridian pathway from the point's location to the organ system it governs.

The Most Useful Points for Self-Acupressure

These seven points cover the most common everyday applications and can be stimulated safely through firm sustained finger pressure (2-3 minutes per point, firm enough to produce a dull, spreading ache at the point — the sensation TCM calls 得气, dé qì, "obtaining qi"):

ST36 — Zusanli (足三里, "Leg Three Miles") Location: Four finger-widths below the kneecap, one finger-width lateral to the tibial crest (the bony ridge of the shinbone). On the outside of the lower leg. Primary actions: Tonifies spleen and stomach qi, supports digestion, builds overall qi and blood, strengthens immune function. Applications: Fatigue, poor digestion, bloating, loose stools, poor immunity. The most widely used point in TCM practice and arguably the most important single point for overall health maintenance. Traditional note: A classical Chinese saying holds that if you want to be healthy past 50, keep Zusanli warm and active. Traditionally stimulated with moxa.

PC6 — Neiguan (内关, "Inner Pass") Location: Three finger-widths above the wrist crease on the inner forearm, between the two tendons. Primary actions: Calms the heart and mind, relieves nausea and vomiting, regulates the chest and stomach. Applications: Nausea (including motion sickness and morning sickness), palpitations, anxiety, chest tightness. The basis for acupressure wristbands used for motion sickness — PC6 is the point they press.

LI4 — Hegu (合谷, "Joining Valley") Location: In the web between the thumb and index finger, at the highest point of the muscle when the thumb and finger are pressed together. Primary actions: Clears wind, relieves pain (particularly headache and facial pain), opens the exterior. Applications: Headache (especially frontal and sinus), toothache, facial pain, colds in the early stage, stress tension in the head and neck. Contraindication: Avoid during pregnancy — LI4 has a descending action that may stimulate uterine contractions.

LV3 — Taichong (太冲, "Great Surge") Location: On the top of the foot, in the depression between the first and second metatarsal bones, approximately two finger-widths back from the web margin. Primary actions: Moves liver qi, calms the mind, relieves headache, regulates menstruation. Applications: Stress-related headache, liver qi stagnation symptoms (chest tightness, irritability, PMS), eye strain from rising liver heat. LI4 and LV3 together form the "Four Gates" (四关, sì guān) — a classic combination for moving qi throughout the body, relieving stress, and clearing headaches.

HT7 — Shenmen (神门, "Spirit Gate") Location: On the inner wrist crease, at the ulnar (pinky) side, in the depression between the tendons. Primary actions: Calms the heart and mind, anchors the shen, relieves insomnia and anxiety. Applications: Insomnia, anxiety, palpitations, poor memory, emotional agitation. The primary point for heart shen disturbance.

SP6 — Sanyinjiao (三阴交, "Three Yin Intersection") Location: Four finger-widths above the inner ankle bone, just behind the tibial border. Primary actions: Tonifies yin, nourishes blood, supports the spleen, regulates menstruation. Applications: Insomnia (particularly the yin deficiency and blood deficiency types), fatigue, menstrual irregularity, digestive weakness. Contraindication: Avoid during pregnancy.

GV20 — Baihui (百会, "Hundred Meetings") Location: At the crown of the head, midway between the ears on the midline. Primary actions: Raises yang, clears the mind, lifts the spirit. Applications: Mental fogginess, low energy in the morning, mild depression, mild prolapse conditions. Stimulated by gentle circular pressure or mild tapping.

Points and Acupressure vs Needling

Acupressure — sustained firm finger pressure on acupuncture points — produces effects that are real but more modest than needling. The mechanisms are different: needling penetrates the tissue and produces the full de qi response; acupressure stimulates surface mechanoreceptors and produces a modified version of the same response.

For self-care purposes, acupressure is safe, accessible, and produces meaningful results for mild presentations of the relevant conditions. The studies on PC6 for nausea are among the best-quality acupressure research and show consistent effect. ST36 acupressure studies for fatigue and digestive support are growing. HT7 for sleep shows modest but consistent effects in small trials.

The limitation of acupressure is precision — finding the exact point location matters, and the first few attempts may miss the point. The indicator is the de qi sensation: when you have the right point and apply sufficient pressure, you should feel a dull, spreading, sometimes radiating ache at the point. If you feel only surface pressure with no spreading sensation, you are either on the wrong location or not pressing firmly enough.

For the acupressure practice that builds on these point locations into a coherent self-treatment framework, the body practices article covers the technique in full. For the acupuncture overview that explains the clinical practice that professional needling represents, the distinction between self-care acupressure and professional acupuncture treatment is important. And for the Baduanjin practice that incorporates point stimulation through specific postural activations, the movement practice provides a complementary approach to many of the same organ-system targets.
