Acupressure
Evidence grade varies by use. See the breakdown on the entry. Read how the Atlas grades evidence.
Evidence is indication-specific and uneven, which is why the overall grade is low. The strongest signal is for nausea and vomiting at the P6/PC6 wrist point. A Cochrane review of PC6 stimulation for postoperative nausea and vomiting pooled 59 randomized trials and 7,667 participants and reported that PC6 stimulation reduced symptoms versus sham (low-certainty evidence) and performed comparably to antiemetic drugs (moderate-certainty). For chemotherapy-induced symptoms, trials report benefit mainly for first-day nausea, not vomiting. For pregnancy-related nausea, Cochrane and later reviews describe insufficient high-quality evidence and mixed individual trials. For pain, anxiety, and sleep, several meta-analyses report reductions, but trials are small, often unblinded, heavily reliant on auricular (ear) acupressure, and at high risk of bias, so these remain preliminary. Reviewers describe a consistently good safety profile, with no serious adverse events reported across the nausea and sleep reviews.

| Treatment | Grade | Notes |
|---|---|---|
| Postoperative nausea and vomiting (P6/PC6) | 3 of 5 | Cochrane review reports 59 RCTs, 7,667 participants; better than sham (low certainty), comparable to antiemetic drugs (moderate certainty). |
| Chemotherapy-induced nausea | 2 of 5 | Trials report benefit mainly for first-day nausea, not vomiting; smaller and more variable evidence base. |
| Pregnancy-related nausea and vomiting | 2 of 5 | Cochrane and later reviews describe insufficient high-quality evidence; individual trials mixed. |
| Pain | 1 of 5 | Some trials report pain reduction (e.g., low back pain) but methodological quality is limited and results inconsistent. |
| Anxiety and sleep | 2 of 5 | Meta-analyses report reductions, but trials are small, often unblinded, and dominated by auricular acupressure; preliminary. |
What can go wrong
Low physical risk when applied with finger pressure. Reported issues are limited to transient soreness or bruising at pressure sites. Caution applies over open wounds, fractures, acute infection, or thrombosis, and during pregnancy point selection should involve a qualified clinician. The main practical risk is opportunity cost: relying on acupressure in place of effective treatment for a condition that needs medical management.
This is something to take to a clinician. The Atlas can tell you what is known about acupressure in general. It cannot tell you what is happening in your body, and the difference matters most for exactly the symptoms that bring people to this page.
Acupressure is the application of sustained finger, thumb, or palm pressure to the same body points used in acupuncture, without needles. It grows out of ancient Chinese manual acupoint traditions later shaped into tui na, Japanese anma, and modern shiatsu, and it shares acupuncture's meridian map of qi channels. The best-supported use is the P6 (Neiguan) point on the inner wrist for nausea and vomiting: a large Cochrane review of P6 stimulation for postoperative nausea reported it beat sham and matched antiemetic drugs, though the reviewers graded the certainty of that evidence as low to moderate. Reviewers describe benefits for chemotherapy nausea as partial, for pregnancy nausea inconsistent, and for pain, anxiety, and sleep still preliminary and dominated by small, often unblinded studies. The clinical finding at P6 stands on its own terms even though the meridian theory offered to explain it has not been anatomically validated. Acupressure is low-cost, self-administrable, and reported to be safe, which is part of why it persists in clinical settings even where the mechanistic story stays contested.

How it is supposed to work
Established mechanism is modest and conventional: sustained manual pressure on the skin and underlying tissue can stimulate mechanoreceptors and sensory nerves, may engage gate-control and descending pain-modulation pathways, and can produce relaxation and expectancy effects that plausibly dampen nausea signaling and perceived pain. The proposed traditional mechanism, that pressing named acupoints unblocks or rebalances qi flowing through meridians, is the claimed framework practitioners use to select points such as P6 (Neiguan) on the inner forearm. That meridian model has no resolved anatomical correlate. Reviews of cadaver and imaging work describe candidate substrates in fascia, connective tissue, and neurovascular bundles, but the scientific community has not confirmed that meridians exist as discrete structures. The clinical question (does pressing this spot help?) and the theoretical question (is it because of qi and meridians?) are separate and carry different evidence.
What people get wrong
Often saidAcupressure has no evidence behind it at all, it is pure placebo.
ActuallyFor postoperative nausea, a large Cochrane review reports P6 stimulation beat sham and matched antiemetic drugs; the catch is that the reviewers graded certainty low to moderate, and other uses are weaker, not that there is zero signal.
Often saidIf P6 reduces nausea, that proves qi and meridians are real.
ActuallyA point can produce an effect without the traditional theory being correct. Meridians have no confirmed anatomical basis, and conventional neural and expectancy mechanisms can account for the clinical result.

Clinically studied acupressure at the P6 point offers natural relief from nausea for travel, pregnancy, and post-surgery.
Skeptical biomedical commentators
There is no conclusive evidence that meridians or acupoints exist as real structures; modest benefits are better explained by ordinary nerve stimulation and expectation.

How we got here
Acupressure descends from the manual acupoint pressing of ancient China, where applying finger and palm pressure along channels of qi predates and runs parallel to needle acupuncture. The foundational text is the Huangdi Neijing (Yellow Emperor's Inner Canon), compiled roughly around 100 BCE during and after China's Warring States period, which set out the meridian and acupoint framework shared by both methods. Manual pressing became formalized in Chinese tui na (push-grasp) bodywork, transmitted to Japan over centuries and adapted into anma, with tradition crediting Akashi Kan Ichi around 1320 CE and later popularization by the blind acupuncturist Sugiyama Waichi in the 1600s. In Japan, Tokujiro Namikoshi systematized shiatsu (finger pressure) from anma in the 1940s, opening his institute in Tokyo and winning Japanese legal recognition for the practice by the 1950s and 1960s. The Western label acupressure is a 20th-century umbrella term for these older Asian pressing traditions.
Manual pressing of body points is among the oldest documented therapies in China, where it sat alongside needling within the same theory of qi and meridians codified in the Huangdi Neijing around 100 BCE. It matured into tui na bodywork, one of the formal branches of classical Chinese medicine. The technique traveled east to Japan, where anma developed in the medieval period and was widely practiced, often by blind practitioners, into the Edo era. In the 20th century the Japanese practitioner Tokujiro Namikoshi reframed pressure-point work as shiatsu, deliberately leaning on Western anatomy rather than meridian language to gain legal recognition, which Japan granted across the 1950s and 1960s. Acupressure spread to the United States and Europe in the 1960s and 1970s as part of broader interest in Asian healing practices. The P6 anti-nausea application later drew formal clinical study and entered hospital and obstetric settings via commercial wristbands.

How it is understood
Acupressure sits inside living Chinese and Japanese bodywork lineages (tui na, anma, shiatsu) that remain practiced and taught within their cultures of origin. It is not a closed ceremonial practice, and its diffusion has been largely commercial rather than extractive of a sacred rite, so it does not raise the same sovereignty stakes as ceremonial plant or ritual traditions.
Where scholars disagree
There is broad agreement that P6 acupressure can reduce some nausea, but sharp disagreement over why it works. Practitioners attribute effects to qi moving through meridians; critics hold that meridians have no confirmed anatomical reality and that observed benefits run through conventional neural, gate-control, expectancy, and placebo pathways.
Traditional Chinese and shiatsu practitioners and proponents
Pressing specific acupoints such as P6 (Neiguan) regulates the flow of qi along defined meridians, and this channel system is the operative basis for the clinical effects.
What it rests onThe meridian-and-acupoint framework codified in the Huangdi Neijing; clinical traditions of tui na, anma, and shiatsu; reviews proposing fascia or connective-tissue correlates for meridians.
Mainstream biomedical reviewers
There is no conclusive evidence that acupoints or meridians exist as discrete structures; any genuine effects are better explained by mechanoreceptor and sensory-nerve stimulation, descending pain modulation, relaxation, and expectancy.
What it rests onAnatomical and imaging studies that fail to confirm meridians; Cochrane's low-to-moderate certainty grades; trials where point specificity is weak and sham responses are large.
This disagreement is live. It has not settled.
