We have written about thirty conditions on this site, and for most of them the honest summary has been some version of “promising, low certainty, worth trying”. This one is different, and it is worth saying so clearly.
Stimulation of a single point on the wrist for nausea is among the best-evidenced things in this field.
What the evidence shows
A Cochrane systematic review of stimulation at P6 for postoperative nausea and vomiting pooled 26 trials and more than 3,000 patients. It found real P6 stimulation superior to sham for both nausea and vomiting, in adults and in children.
That combination — large trial count, consistent direction, and beating sham rather than merely beating no treatment — is what the other conditions on this site mostly lack.
| Comparison | Finding | Why it matters |
|---|---|---|
| vs sham stimulation | Superior for nausea and vomiting, 26 trials, 3,000+ patients | Passes the hard test |
| vs antiemetic drugs | Equivalent for vomiting; possibly better for nausea | A real alternative, not just an add-on |
| Adults vs children | Effective in both | Unusual consistency |
| Needles vs acupressure bands | Similarly effective | You do not necessarily need a practitioner |
| Guideline status | Recommended in Society for Ambulatory Anesthesia consensus guidance | It has crossed into mainstream practice |
The professional body for anaesthesiology, the American Society of Anesthesiologists, publishes patient information on what to expect around surgery if that is your situation.
Where P6 is, and how to find it
This is worth knowing because you can use it yourself.
- Turn one arm palm up.
- Place three fingers of the other hand across the wrist, with the edge of your index finger on the wrist crease.
- Just past your ring finger, you are at the right level.
- Feel for the two tendons running down the middle of the forearm. The point sits between them.
- Press firmly for a minute or two, then swap arms.
An acupressure band does the same job continuously, which is why they are sold for travel and morning sickness. The button should sit on that spot, not on the back of the wrist — worn wrongly they do nothing, which is probably why some people conclude they do not work.
Why we are saying this so plainly
Most of this site is careful to the point of being unhelpful about what acupuncture can do, because most of the evidence deserves that caution. Fibromyalgia, menopausal hot flashes and tennis elbow all get an honest “the trials do not really support this”.
That is exactly what makes it worth saying when a use does have good support. A practice that claims everything works tells you nothing. One that tells you where the evidence is thin has earned the right to point at the place where it is not.
What it covers, and what it does not
The strength of the evidence varies a lot by cause, and it is worth being specific rather than claiming it helps “nausea”.
| Cause | Evidence | Sensible use |
|---|---|---|
| After surgery | Strongest | Discuss with your anaesthetist; bands are easy to use |
| Motion sickness | Reasonable | A band before travelling is low cost and low risk |
| Pregnancy | Some support | Bands are commonly used; raise it with your midwife or doctor |
| Chemotherapy | Some support | Only alongside your oncology team, never instead |
| Migraine-related | Indirect | Treating the migraine matters more |
| New, unexplained nausea | Not applicable | Needs a diagnosis first |
Why one point, and why the wrist
It is a fair question. Most of acupuncture involves individual diagnosis and a different set of points for each person. Nausea is the exception: the research has converged on a single point used the same way for almost everyone.
P6 sits directly over the median nerve, which is thought to be part of why stimulating it has such a consistent effect. It is also the reason the technique transfers so readily to a band — there is no point selection to get wrong.
What else helps
- Ginger has its own modest evidence, and works independently of the acupressure.
- Small, dry, plain food rather than nothing at all. An empty stomach usually makes nausea worse.
- Cool air and a fixed horizon for motion sickness — front seat, window open, eyes on the road.
- Sips rather than glasses. Large volumes come straight back.
- Avoid strong smells, which are a bigger trigger than most people credit.
None of this needs a practitioner. We would rather you knew it than paid us for it.
When to see a doctor
Please seek medical advice for nausea that is persistent or unexplained; nausea with severe abdominal pain, a headache unlike any before, chest pain, or a stiff neck; vomiting blood or anything resembling coffee grounds; inability to keep fluids down for more than a day; or nausea alongside unexplained weight loss.
Booking a session in Beverly
Acupuncture is $75 a session, published with everything else on our rates page. Honestly though, for travel sickness a five-dollar wristband is the sensible first step, and we would rather tell you that than book you in.

Frequently asked questions
Does acupuncture really work for nausea?
For this one, the evidence is unusually good. A Cochrane review of stimulation at the P6 point covering 26 trials and more than 3,000 patients found it superior to sham for both nausea and vomiting, in adults and children. It is one of very few uses that reaches this standard of support.
Where is the P6 point?
On the inner forearm, about three finger-widths up from the wrist crease, between the two tendons you can feel running down the middle. Its traditional name is Neiguan, meaning inner gate. It sits over the median nerve.
Do the wristbands work as well as needles?
The reviews found P6 stimulation similarly effective across methods, invasive and non-invasive. So an acupressure band is a reasonable option, particularly for travel sickness where you want something you can apply yourself.
Is it as good as anti-sickness medication?
Pooled trial data put P6 stimulation as broadly equivalent to antiemetics for vomiting, and possibly better for nausea itself. It is not a replacement for prescribed medication, but it is a genuine option alongside it, or where medication is unsuitable.
What kinds of nausea does this cover?
The evidence is strongest for nausea after surgery. There is also support for chemotherapy-related and pregnancy-related nausea, though those need to be managed with the team treating you, not instead of them. Motion sickness is a common everyday use.
