Nausea and vomiting are not a single illness in TCM - they are a distress signal that Stomach Qi is flowing the wrong way. Instead of descending, it rebels upward, and the reason behind that rebellion can be as different as a heavy meal, a wave of frustration, or a long-standing digestive weakness. This page walks you through the six most common patterns that cause nausea and vomiting, each with its own triggers, its own character, and its own treatment.
Nausea is an unpleasant sensation of needing to vomit, while vomiting is the forceful expulsion of stomach contents. These symptoms can arise from many causes: gastroenteritis, food poisoning, motion sickness, pregnancy, migraines, medication side effects, or emotional distress. Diagnosis relies on a careful history and physical exam, sometimes supported by blood tests or imaging when a more serious underlying condition is suspected.
Conventional treatments
Conventional management often includes antiemetic drugs such as ondansetron, metoclopramide, or promethazine, along with dietary adjustments (the BRAT diet - bananas, rice, applesauce, toast) and oral rehydration solutions. When nausea is a side effect of other medications, the dose may be adjusted or the drug changed. In pregnancy or after surgery, specific protocols are followed to minimize risk.
Where conventional treatment falls short
Antiemetics can bring quick relief but they often work by blocking signals in the brain or gut without addressing the underlying pattern that makes nausea keep coming back. Side effects like drowsiness, dry mouth, or restlessness are common, and long-term use is rarely a satisfying solution. The conventional model also lacks a framework for distinguishing why one person vomits after stress while another does so after a fatty meal - a distinction that sits at the very heart of TCM diagnosis.
How TCM understands nausea or vomiting
In TCM, the Stomach is the central pivot of digestion. Its job is to receive food and send it downward - a movement called Stomach Qi descending. When that downward movement fails, Qi rebels and rises, bringing nausea and vomiting. So the immediate problem is always rebellious Stomach Qi, but the real question is what caused it to rebel.
The trigger can be something the Stomach cannot process, like a heavy, greasy meal that sits and ferments (Food Stagnation). It can be an emotional storm - frustration or anger that makes Liver Qi attack the Stomach, forcing it to churn upward. It can be a sticky accumulation of Dampness and Heat, or a cold, watery buildup of Phlegm-Fluids that drowns the digestive fire. And sometimes the problem isn't an excess at all, but a deficiency: a Stomach that has lost its warming Yang and can no longer move anything downward, or a Stomach so dry and Yin-deficient that it cannot guide food along.
This is why a TCM practitioner asks so many questions about the vomit itself. Sour, foul-smelling vomit that brings relief points to Food Stagnation. Vomiting of thin, watery fluid with a splashing sound in the belly suggests Phlegm-Fluids. Dry retching with a parched mouth signals Yin Deficiency. The trigger - stress, cold, overeating - and the tongue and pulse confirm the pattern. What Western medicine calls "nausea and vomiting" TCM sees as six different landscapes, each needing its own map.
「伤寒五六日，中风，往来寒热，胸胁苦满，默默不欲饮食，心烦喜呕……小柴胡汤主之。」
"In Lesser Yang disease, alternating chills and fever, fullness and discomfort in the chest and hypochondrium, no desire to eat or drink, vexation, and frequent vomiting... Xiao Chai Hu Tang governs."
How a TCM practitioner diagnoses nausea or vomiting
Inside the consultation
A practitioner begins by asking what the nausea feels like, when it strikes, and what the vomit looks and smells like. The quality and timing of the symptom are the first clues that point toward one pattern rather than another. A sudden onset after a heavy meal tells a very different story from a chronic, low‑grade queasiness that worsens with fatigue or stress.
When nausea strikes shortly after overeating and the vomit is sour and foul‑smelling, the picture points to Food Stagnation in the Stomach. The person feels a bloated, uncomfortable fullness in the upper abdomen. The tongue coating is thick and greasy, and the pulse feels slippery. This pattern signals a digestive backlog that needs clearing rather than an underlying weakness.
If nausea flares during stress or frustration, and is joined by belching, acid reflux, and a distended feeling along the ribs, the root is often Liver Qi Stagnation invading the Stomach. The tongue edges may look red, and the pulse has a taut, wiry quality. The emotional trigger and the rib‑side discomfort are the key signs that separate this from simple indigestion.
Vomiting of watery, thin fluid and a sensation of heaviness or fullness in the chest suggest Phlegm‑Fluids accumulating in the Stomach. The tongue typically has a white, greasy coating, and the pulse is slippery. This pattern often arises when fluid metabolism is sluggish, so the practitioner will ask about a history of digestive dampness or a feeling of foggy heaviness.
When nausea comes with a sticky taste, a heavy body sensation, and a stuffy fullness, Damp‑Heat in the Stomach is a likely culprit. The tongue is red with a thick, yellow, greasy coating, and the pulse feels slippery and rapid. This pattern often follows rich, greasy foods or hot, humid weather. The yellow coating and rapid pulse confirm that Heat is present alongside Dampness.
Chronic, low‑grade nausea with vomiting of clear fluid and cold hands and feet points to Stomach Yang Deficiency with Cold. The tongue appears pale with a white coating, and the pulse is slow and weak. In contrast, dry retching, a burning sensation in the stomach, and nausea that worsens in the afternoon suggest Stomach Yin Deficiency. Here the tongue looks red and peeled, with a thin and rapid pulse.
TCM Patterns for Nausea Or Vomiting
In TCM, the aim is to address the root cause, not just the symptom — it calls that root cause a “pattern.” The same nausea or vomiting can come from several different patterns, each treated differently. The quickest way to find yours is the quiz below.

Which signs match your experience?
It is very common to see parts of yourself in more than one pattern. For example, both Food Stagnation and Damp‑Heat can cause a thick tongue coating and a feeling of fullness, while emotional stress can trigger Liver Qi invading the Stomach as well as aggravate a pre‑existing Phlegm‑Fluid tendency. These patterns are not rigid boxes; they often blend or follow one another.
To narrow the picture, notice which feature is strongest and what makes it better or worse. If overeating reliably sets off vomiting of sour, undigested food, Food Stagnation is central. If stress and a tight, distended feeling in the ribs dominate, look toward Liver Qi. Vomiting of clear, watery fluid and cold limbs point to a Yang deficiency, while dry retching and a burning sensation suggest Yin deficiency.
Because these patterns can overlap, a professional diagnosis that includes tongue and pulse examination is invaluable. A practitioner can detect subtle signs like a wiry quality in the pulse or a red tip of the tongue that you might miss. If nausea is severe, persistent, or accompanied by weight loss or blood, see a healthcare provider promptly rather than trying to self‑treat.

Formulas traditionally used for nausea or vomiting
9 formulas across the patterns above. The right one depends on your pattern — start with the quiz if you're unsure which fits.
A gentle, time-tested formula for the uncomfortable, heavy feeling after overeating or consuming rich, greasy foods. It helps break down accumulated food, relieves bloating, acid reflux, nausea, and belching, and restores normal digestive movement. Often described as 'digestive first aid' in Chinese medicine, it works by clearing the blockage rather than masking symptoms.
A classical formula that harmonises the body when an illness is stuck between the surface and the interior, causing alternating chills and fever, chest and rib-side discomfort, poor appetite, nausea, and irritability. It is one of the most widely used formulas in Chinese medicine, applied to a broad range of conditions involving the Liver, Gallbladder, and digestive system.
A classical two-herb formula used for digestive problems caused by excess Liver Heat disrupting the Stomach. It is best known for treating acid reflux, sour regurgitation, nausea or vomiting, rib-side pain, and bitter taste in the mouth, especially when these symptoms are triggered or worsened by stress and frustration. The formula works by cooling Liver Fire and restoring the Stomach's natural downward movement.
A classical four-herb formula used to address dizziness, heart palpitations, chest fullness, and shortness of breath caused by a weak digestive system failing to properly process fluids. It gently warms the body and helps move excess fluid accumulation, particularly when someone feels heavy, waterlogged, or dizzy upon standing.
A classical two-herb formula used to stop nausea and vomiting caused by fluid and phlegm accumulating in the stomach. It is especially suited for vomiting with no thirst, a feeling of fullness below the chest, and a white slippery tongue coating. Often regarded as the foundational anti-nausea prescription in Chinese medicine.
A classical formula for treating acute digestive upsets caused by a combination of Dampness and Heat lodging in the Stomach and intestines. It addresses simultaneous vomiting and diarrhea, a feeling of fullness and stuffiness in the chest and upper abdomen, irritability, and dark scanty urine, particularly during hot and humid seasons.
A classical warming formula used to strengthen the digestive system when it has become weakened by internal cold. It addresses symptoms like watery diarrhea, nausea, abdominal pain relieved by warmth and pressure, poor appetite, and a general feeling of coldness. It works by warming the core of the body and restoring the Spleen and Stomach's ability to process food and fluids.
A warming formula used to strengthen the digestive system and restore warmth to the body. It is used for people who feel deeply cold in the abdomen, experience chronic loose stools or diarrhea, vomiting, poor appetite, and cold hands and feet caused by severe weakness and cold in the Spleen, Stomach, and Kidneys.
A classical formula for nourishing the lungs and stomach, used for persistent dry cough, throat dryness, shortness of breath, or nausea caused by depleted fluids in the respiratory and digestive systems. It works by replenishing moisture in the body while gently directing upward-rising Qi back downward.
Excess patterns like Food Stagnation or Damp-Heat often improve within one to two weeks of herbal therapy and acupuncture. Stress-related Liver-Stomach patterns may take two to four weeks, depending on the emotional landscape. Deficiency patterns - Stomach Yang or Yin deficiency - require rebuilding and usually show steady progress over four to eight weeks, with deeper change unfolding over several months.
Treatment principles
All TCM treatment for nausea and vomiting revolves around one aim: restore the Stomach's downward movement. The strategy for doing that, however, changes completely depending on what is blocking or weakening the Stomach. In excess patterns, the priority is to clear the obstruction - digesting food stagnation, soothing constrained Liver Qi, transforming Phlegm-Fluids, or draining Damp-Heat. In deficiency patterns, the focus shifts to replenishing what is missing - warming Stomach Yang or nourishing Stomach Yin - so the organ can once again perform its natural descending function.
Acupuncture and herbs work together. Points like Neiguan (PC-6), Zusanli (ST-36), and Zhongwan (REN-12) appear across almost all patterns because they directly regulate Stomach Qi, but additional points are chosen to address the root: Taichong (LR-3) for Liver Qi stagnation, Fenglong (ST-40) for Phlegm, Yinlingquan (SP-9) for Damp-Heat, and moxibustion on Shenque (REN-8) for Yang deficiency. This layered approach is why TCM can treat both the acute symptom and the chronic tendency.
What to expect from treatment
Most patients notice a clear improvement in nausea within the first one to three weeks of weekly acupuncture combined with daily herbal formulas. Acute episodes, such as nausea after a heavy meal, often settle within a day or two of treatment. Chronic patterns rooted in deficiency take longer - expect gradual, steady progress over four to eight weeks, with the frequency and intensity of nausea decreasing step by step. Your practitioner will adjust the herbal formula as your pattern shifts, so the treatment evolves with you.
General dietary guidance
When nausea is active, favour warm, cooked, and easily digestible foods: congee, steamed vegetables, mild soups, and small amounts of ginger tea. Ginger is a gentle Stomach warmer that helps Qi descend. Avoid cold drinks, raw salads, fried foods, dairy, and anything overly sweet or greasy - these create Dampness and burden the Stomach. Eat small portions at regular intervals rather than three large meals, and try not to lie flat immediately after eating. Even after the nausea passes, maintaining a warm, moderate diet helps prevent recurrence.
Combining TCM with conventional treatment
TCM and conventional care can work side by side. If you are taking antiemetics, do not stop them abruptly; instead, coordinate with your doctor to taper as your symptoms improve. Herbs that descend Stomach Qi are generally safe with standard anti-nausea drugs, but always bring a full list of your medications to your TCM consultation. If you are on blood thinners, note that some herbs (such as Dang Gui or Chuan Xiong) may not appear in nausea formulas, but your practitioner still needs to know. Pregnant women should only use TCM under the guidance of a practitioner experienced in obstetric care.

Safety & special considerations
-
Vomiting blood or material that looks like coffee grounds — This may indicate bleeding in the stomach or esophagus and requires immediate emergency evaluation.
-
Severe abdominal pain, especially if it is constant or comes in waves — Could signal a surgical emergency such as appendicitis, bowel obstruction, or pancreatitis.
-
High fever with stiff neck and vomiting — These can be signs of meningitis; seek emergency care without delay.
-
Signs of severe dehydration - dizziness when standing, very dry mouth, little or no urine for 8 hours — Inability to keep fluids down can lead to dangerous dehydration, especially in children and older adults.
-
Vomiting after a head injury — This may indicate a concussion or more serious brain injury and should be evaluated in an emergency department.
-
Inability to keep down any food or liquid for more than 24 hours — Prolonged vomiting can cause electrolyte imbalances and requires medical intervention to prevent complications.
Audience-specific guidance — open what applies to you
During pregnancy, the growing fetus can disrupt the normal descent of Stomach Qi, making nausea and vomiting very common. The most frequent TCM patterns are Phlegm-Fluids in the Stomach and Liver Qi invading the Stomach. However, deficiency patterns like Stomach Yang Deficiency may also appear if the mother is constitutionally weak.
Herbal treatment must be cautious. Ban Xia (Pinellia) is a key herb for vomiting but is traditionally considered risky in pregnancy; many practitioners replace it with Zhu Ru or fresh ginger. Acupuncture at Neiguan (PC6) is a safe and effective alternative. Any formula containing strong Qi-moving or blood-moving herbs should be avoided unless prescribed by a qualified professional.
If a breastfeeding mother takes herbs for nausea, some active compounds can pass into breast milk. Bitter-cold herbs like Huang Lian (Coptis) used for Damp-Heat patterns may cause loose stools in the infant. For nursing mothers with nausea, milder, food-grade herbs such as ginger, Chen Pi (tangerine peel), and Shan Zha (hawthorn) are preferred. Acupuncture remains a safe option with no risk to the baby. Always inform your practitioner that you are breastfeeding so they can select the safest approach.
In children, nausea and vomiting are most often caused by Food Stagnation due to overeating or improper diet. The classic formula Bao He Wan is frequently used, but the dosage must be reduced to one-quarter to one-half of the adult dose depending on the child's age and weight. Children cannot always describe their symptoms clearly, so diagnosis relies on observation: a thick, greasy tongue coating, a bloated belly, and vomiting of undigested food with a sour smell are telltale signs. Acupressure at Neiguan (PC6) and Zusanli (ST36) can be taught to parents for mild cases. For recurrent or severe vomiting, professional evaluation is essential to rule out more serious conditions.
In the elderly, nausea and vomiting are more likely to stem from deficiency patterns, particularly Stomach Yang Deficiency and Stomach Yin Deficiency. The digestive fire weakens with age, leading to coldness and poor digestion, or the Stomach's fluids dry up, causing dry retching. Treatment should use gentle, tonifying formulas like Li Zhong Wan or Mai Men Dong Tang, with dosages reduced to about two-thirds of the standard adult dose. Older patients often take multiple medications, so herb-drug interactions must be carefully checked. Acupuncture and mild dietary therapy are often safer and better tolerated than strong herbal decoctions.
Evidence & references
Acupuncture at the Neiguan (PC6) point has the strongest evidence base for nausea and vomiting, with multiple Cochrane systematic reviews confirming its effectiveness for postoperative nausea, chemotherapy-induced nausea, and pregnancy-related nausea. The evidence is robust and consistent across many randomized controlled trials.
For Chinese herbal medicine, the evidence is less definitive. Studies on formulas such as Xiao Ban Xia Tang and Bao He Wan show promise for functional dyspepsia and nausea, but many are small, conducted in China, and lack rigorous blinding. More high-quality, international trials are needed to confirm these findings.
Key clinical studies
This Cochrane review assessed the effectiveness of P6 acupoint stimulation for preventing postoperative nausea and vomiting. It found that P6 stimulation significantly reduced the risk of nausea and vomiting compared to sham treatment, with a risk ratio comparable to antiemetic drugs.

Frequently asked questions
Common questions about using Traditional Chinese Medicine for nausea or vomiting.
For many people, yes - especially when the nausea is acute and the underlying pattern is excess in nature. The point Pericardium-6 (Neiguan, on the inner wrist) is famous for calming rebellious Stomach Qi and can be needled or pressed during an episode. In a clinical setting, acupuncture often reduces the urge to vomit within minutes. Chronic nausea may take a few sessions to settle fully.
Generally yes, but you should always tell both your TCM practitioner and your prescribing doctor what you are taking. Herbs that descend Stomach Qi, such as Ban Xia (Pinellia), are commonly used alongside conventional antiemetics without issue. If your medication causes drowsiness, your practitioner will avoid herbs with strong sedative properties. Never stop prescribed medication suddenly - work with your doctor to adjust doses as your symptoms improve.
Start with the simplest, most neutral foods: plain congee (rice porridge), a slice of dry toast, or a few sips of warm ginger tea. Ginger is a classic TCM remedy that gently warms the Stomach and directs Qi downward. Avoid cold, raw, greasy, and dairy-heavy foods, which are harder to digest. Eat tiny amounts frequently rather than large meals, and rest in a semi-upright position after eating.
Yes - this is a textbook Liver Qi invading the Stomach pattern. The formula Xiao Chai Hu Tang (Minor Bupleurum Decoction) with Zuo Jin Wan (Left Metal Pill) soothes the Liver, clears heat, and sends rebellious Stomach Qi downward. Many patients notice that within a few weeks, their gut feels less reactive to emotional triggers. Acupuncture at points like Taichong (Liver-3) and Neiguan (PC-6) reinforces this calming effect.
TCM has a long tradition of treating nausea in pregnancy, and our dedicated Morning Sickness page goes into detail on the specific patterns involved. The core principle is the same - calming rebellious Stomach Qi - but the herbal choices are carefully selected to be safe for both mother and baby. Always consult a qualified practitioner rather than self-prescribing during pregnancy.
Yes. Pericardium-6 (Neiguan) is the most famous anti-nausea point. Find it three finger-widths below the wrist crease, between the two tendons on the inner forearm. Press firmly with your thumb for two to three minutes while breathing slowly. Stomach-36 (Zusanli), four finger-widths below the kneecap and one finger-width outside the shinbone, is also useful for strengthening digestion. These points are safe to use as often as needed.
This is a common concern. Your practitioner can adjust the formula to be gentler on the Stomach or prescribe it as a tea sipped very slowly in tiny amounts. Some patients start with acupuncture alone to settle the vomiting first, then introduce herbs once the Stomach is calmer. In severe cases, the herbs can be administered as a retention enema or through acupoint injection, though this is less common.
