PC6 Acupressure for Morning Sickness
Nausea and vomiting are common during early pregnancy, and despite the name “morning sickness,” symptoms can occur at any time of day. One non-drug technique some pregnant patients try is gentle pressure on PC6, also called P6 or Neiguan, an acupressure point on the inner wrist.
Does PC6 Acupressure Help Morning Sickness?
PC6 has been studied extensively for nausea, but the answer depends on the type of nausea being discussed. Evidence for P6 stimulation is strongest for postoperative nausea and vomiting.
For nausea and vomiting during pregnancy, studies of P6 acupressure have produced mixed results and the evidence remains limited. That does not mean you cannot try gentle wrist acupressure. It means it should be presented as a low-complexity complementary technique, not as a proven treatment or replacement for prenatal medical care.
What Is Morning Sickness?
Nausea and vomiting of pregnancy is extremely common. According to the American College of Obstetricians and Gynecologists, symptoms usually begin before nine weeks of pregnancy. For many people they improve by around 14 weeks, although symptoms can last longer.
“Morning sickness” can be a misleading name because nausea may occur in the morning, afternoon, evening, or throughout the day.
The exact cause is not fully understood. Hormonal changes during early pregnancy are believed to contribute, and changes in smell and taste can make certain foods or odors much harder to tolerate.

Where Is the PC6 Pressure Point?
PC6, also written as P6 and known as Neiguan in Traditional Chinese Medicine, is located on the palm-side of the forearm near the wrist. It is the point targeted by many commercially available nausea and motion-sickness wristbands.
How to Find PC6 on Your Wrist
Turn one hand so your palm faces upward.
Place the first three fingers of your opposite hand across the inside of your wrist, beginning just below the wrist crease.
The PC6 point is approximately three finger-widths below the wrist crease, centered between the two prominent tendons running along the inner forearm.
Place your thumb or fingertip on the point and apply firm but comfortable pressure.
Use a small circular motion for approximately two to three minutes, then repeat on the other wrist.
Pressure should feel firm but should not hurt. Memorial Sloan Kettering recommends reducing pressure if the point becomes painful.
Do not apply acupressure over an open wound, rash, significant redness, swelling, warmth, infection, IV line, or other irritated tissue.
Memorial Sloan Kettering Cancer Center provides very similar instructions for locating and pressing P6: see MSK’s P6 acupressure instructions .
Messina Acupuncture also has a more detailed guide devoted specifically to this point: read the complete P6 Neiguan pressure point guide .
What Does the Research Say About PC6?
PC6 has been studied in several different nausea settings. It is important not to combine those studies into one blanket claim that PC6 “works for nausea” in every situation.
Pregnancy Evidence Is Mixed
A Cochrane review examining treatments for nausea and vomiting in early pregnancy included studies of P6 acupressure, P6 electrical stimulation, acupuncture, ginger, medications, and other strategies.
The review concluded that evidence for P6 acupressure during pregnancy was limited. Study methods differed considerably and results were not consistent enough to establish P6 acupressure as a reliably effective treatment for morning sickness.
That distinction matters. PC6 may still be reasonable for someone who wants to try a simple complementary technique, but pregnant patients should not be told that research has proven it will stop nausea or vomiting.

Where the PC6 Evidence Is Stronger: Nausea After Surgery
Research on PC6 is stronger for postoperative nausea and vomiting than it is for pregnancy-related nausea.
An updated Cochrane review published with evidence current through June 2025 evaluated 77 studies involving 9,847 participants. The review found that both invasive PC6 stimulation, such as acupuncture, and noninvasive stimulation, such as acupressure wristbands, may reduce nausea and vomiting following surgery.
The combination of PC6 stimulation with standard anti-nausea medication may also provide additional benefit in some patients.
That evidence helps explain why PC6 continues to be studied and used clinically, but postoperative findings should not automatically be applied to morning sickness.

Is PC6 Acupressure Safe During Pregnancy?
Gentle pressure on the wrist is noninvasive, but pregnancy is still a time when self-treatment should stay simple.
Keep It Gentle
PC6 uses pressure on the inner wrist and does not involve inserting needles. Use firm but comfortable pressure and stop if the technique produces pain, unusual numbness, worsening nausea, dizziness, or another concerning symptom.
Do Not Build Your Own Point Protocol
Pregnancy acupuncture involves additional clinical considerations. Rather than following lists of supposedly “safe” and “unsafe” points online, tell your licensed acupuncturist that you are pregnant and coordinate care with your obstetric provider.
Keep Your OB or Midwife Informed
If nausea is affecting your ability to eat, drink, work, sleep, or function normally, tell your obstetric care provider rather than relying exclusively on acupressure.
Acupressure Can Be Used Alongside Care
Using PC6 does not prevent you from using evidence-based dietary strategies or medication recommended by your obstetric provider. Complementary care should complement standard care, not replace it.
What Else Helps With Morning Sickness?
Start With Established Pregnancy-Nausea Care
ACOG recommends practical dietary and lifestyle measures such as avoiding an empty stomach, trying small frequent meals, and choosing foods you can tolerate.
If those measures are not enough, vitamin B6 may be recommended. Doxylamine can be added when appropriate, and other anti-nausea medications are available when symptoms remain significant.
Talk with your obstetric provider before starting medication, supplements, or a new treatment during pregnancy.
Acupressure can sit alongside these options. It does not have to compete with them.
Acupressure vs. Acupuncture for Pregnancy Nausea
Acupressure
Acupressure uses manual pressure rather than needles. PC6 is easy to reach, so it can be taught as a self-care technique that patients can use at home.
Because it is noninvasive and does not require an appointment every time nausea occurs, it may be an appealing option to try alongside prenatal medical care.
Acupuncture
Acupuncture uses sterile, single-use needles at selected points. A licensed acupuncturist considers the patient’s health history, pregnancy status, symptoms, and broader physical pattern before selecting points.
Current evidence does not justify telling pregnant patients that acupuncture is automatically “stronger” or longer-lasting than PC6 acupressure for morning sickness.
The Traditional Chinese Medicine Explanation
In Traditional Chinese Medicine, nausea is commonly described as Stomach Qi moving upward rather than downward. PC6 has traditionally been selected in patterns involving nausea and vomiting.
That is a traditional clinical framework, not a proven biomedical mechanism. Modern researchers have explored neurological, gastrointestinal, sensory, and autonomic explanations for PC6 stimulation, but no single mechanism fully explains its effects.
Messina Acupuncture PC uses traditional point theory while discussing the limits of current research plainly. You do not need to accept the concept of Qi as literal physiology in order to understand why PC6 has historically been selected and why researchers continue to study it.

This article is intentionally focused on PC6 because it is easy to locate, widely studied, and commonly used for nausea.
Pregnancy is not the ideal time to build a treatment protocol from a long online list of acupuncture points. If PC6 is not helping enough, the next step should be discussing persistent symptoms with your obstetric provider and, if desired, having a licensed acupuncturist evaluate whether professional treatment is appropriate.
What About Nausea That Is Not Related to Pregnancy?
PC6 has also been studied or used as a complementary technique for other types of nausea. The quality of evidence is not identical for every condition.
Postoperative Nausea
This is where current evidence for PC6 stimulation is strongest. PC6 may be used alongside standard anti-nausea medication rather than instead of it.
Treatment-Related Nausea
NCCIH reports evidence that acupuncture may help manage cancer-treatment-related nausea and vomiting, although much of the research predates current antiemetic standards. Any acupuncture during cancer treatment should be coordinated with the oncology team.
Motion Sickness
P6 wristbands are widely marketed for motion sickness, but results vary. Travelers should use standard motion-sickness prevention or medication when appropriate rather than assuming a wristband will reliably prevent symptoms.

When Morning Sickness Needs Medical Attention
Contact Your Obstetric Provider if You Cannot Stay Hydrated
Nausea and vomiting can become medically significant when you cannot retain food or fluids or begin losing weight.
ACOG recommends contacting your obstetric provider if you have signs of dehydration such as very little dark urine, inability to urinate, inability to keep liquids down, dizziness or fainting when standing, or a racing or pounding heartbeat.
Severe nausea and vomiting with significant weight loss and dehydration may be hyperemesis gravidarum and can require medical treatment, IV fluids, medication, or hospitalization.
New nausea and vomiting beginning for the first time after nine weeks, abdominal pain, fever, headache, or other unusual symptoms may also prompt your obstetric provider to look for another cause.

Frequently Asked Questions About PC6 and Morning Sickness
Where is PC6 for nausea?
PC6, also called P6 or Neiguan, is located on the inner forearm approximately three finger-widths below the wrist crease, between the two prominent tendons.
How long should I press PC6?
One commonly taught method is to apply firm but comfortable circular pressure for approximately two to three minutes and then repeat on the opposite wrist. Pressure should not be painful.
Does PC6 acupressure work for morning sickness?
Studies have investigated P6 acupressure for nausea and vomiting in pregnancy, but results have been inconsistent and the overall evidence remains limited. It can be considered a complementary self-care technique rather than a proven treatment.
Are nausea wristbands the same as PC6 acupressure?
Many nausea and motion-sickness wristbands are designed to place a small button directly over the P6 point so that pressure is maintained without manually pressing the wrist.
Is PC6 acupressure safe during pregnancy?
Gentle wrist pressure is noninvasive, but pregnant patients should discuss persistent nausea with their obstetric provider and should not replace indicated prenatal treatment with acupressure. Stop if pressing the point causes pain or worsening symptoms.
Should I use other acupuncture points for morning sickness?
Rather than building a pregnancy treatment protocol from online point lists, use PC6 as a simple self-care technique and have any broader acupuncture or acupressure treatment selected by a licensed practitioner who knows you are pregnant.
What if PC6 does not help?
Lack of improvement does not automatically mean you need acupuncture. Tell your obstetric provider about persistent symptoms so that dietary strategies, vitamin B6, doxylamine, anti-nausea medication, hydration, and other appropriate care can be considered.
When is pregnancy nausea an emergency?
Contact your obstetric provider promptly if you cannot keep liquids down, have very little or no urine, feel faint when standing, develop a racing heartbeat, lose significant weight, or show other signs of dehydration. Severe nausea and vomiting can represent hyperemesis gravidarum and requires medical care.
Start With Safe, Coordinated Care
If you are pregnant and interested in acupuncture or acupressure, contact Messina Acupuncture PC to discuss your symptoms and current prenatal care. PC6 can also be taught as a simple wrist-pressure technique to use at home.
