Ginger & digestion: help with stomach and intestinal complaints

Ginger supports digestion and can effectively ease gastrointestinal symptoms. Studies show that it can speed up gastric emptying by 25%, stimulate digestive enzymes and soothe the gut during diarrhoea. Ginger tea can help with nausea and stomach cramps, while its prokinetic effect can relieve constipation. This natural support may improve your wellbeing, even at small amounts of 0.5–1 g a day.

1. Ginger and digestion: can the root support your stomach and gut?

Ginger is a popular home remedy for gastrointestinal symptoms, from nausea to bloating.

Many people swear that the root gets digestion moving and soothes the stomach. But how much truth is there to that? Can ginger really help with problems such as diarrhoea or feeling overly full? 

In this article, we look at how ginger affects the stomach and gut, what the research says and how you can use it for a specific purpose.

2. How ginger supports digestion

Ginger supports digestion in several ways. Its bioactive compounds act directly on the stomach and gut, affecting everything from gastric emptying to motility.

We explain how ginger may help and why the root is so popular for gastrointestinal symptoms.

2.1. Faster gastric emptying: less fullness

Ginger speeds up gastric emptying—a key factor in feeling less full and nauseous.

A 2008 study found that 1.2 g of ginger may shorten gastric emptying time by about 25%.

This means food reaches the gut sooner, which can reduce bloating and ease digestion—helpful when your stomach feels heavy. Faster gastric emptying means the small intestine fills with digested food sooner and sends out hormones that, in turn, tell the brain that an energy supply is available.

2.2. Digestive enzymes: helping the body process food

The pungent compounds in ginger, such as gingerol, stimulate the production of digestive enzymes. These enzymes—in saliva and the pancreas, for example—break food down more efficiently, improving nutrient absorption.

According to another study, ginger, or gingerol, promotes bile production, which makes fat digestion easier. This makes it a natural aid when digestion feels sluggish.

2.3. Gut motility: help with constipation and diarrhoea

Ginger has a prokinetic effect, meaning it encourages gut movement. It can stimulate the intestinal muscles and so relieve constipation.

At the same time, it may have a regulating effect: during diarrhoea, its anti-inflammatory properties may soothe an irritated gut. A 2019 study confirms that ginger improves gut motility—a bonus for balanced digestion.

3. Ginger for gastrointestinal symptoms: what does the science say?

Research suggests ginger may help with certain symptoms, but it is not always the answer. Let’s look at what studies say about ginger’s effects on the stomach and gut.

3.1. Ginger tea: relief from stomach cramps and nausea

Ginger tea is a classic for stomach complaints—and for good reason. A 2014 study found that ginger reduced nausea in pregnant women by up to 40%, thanks to its antiemetic (nausea-relieving) effect.

It may also help with stomach cramps: its pungent compounds relax the muscles and promote circulation. It is not an instant fix, but may gently soothe the stomach.

3.2. Ginger for diarrhoea: effects and limitations

Ginger can cut both ways when it comes to diarrhoea. Its anti-inflammatory properties may soothe an irritated gut, as a 2019 study suggests—particularly in mild cases caused by irritable bowel syndrome or infections.

However, the evidence is lacking for severe diarrhoea, for example when caused by bacteria such as Salmonella.

4. How to use ginger for your stomach and gut

Ginger may ease gastrointestinal symptoms—but only when used appropriately.

How you prepare it and how much you use can determine whether it supports digestion or irritates your stomach.

Here we show you how to use ginger effectively to soothe your stomach and support digestion.

4.1. Ginger tea recipe to support digestion

This simple ginger tea may help with nausea and soothe the stomach:

• Ingredients: 1–2 cm fresh ginger (about 5 g), 250–400 ml hot water, optional: 1 tsp honey.
• Method:
  1. Slice it thinly so the active compounds are released as effectively as possible.
  2. Pour boiling water over it and leave to steep for 5–10 minutes.
  3. Strain out the slices and add honey if you like—this softens the pungency and may also soothe the stomach.
• Tip: Sip the tea slowly, especially if you have stomach cramps or after a heavy meal.

At around 1 g of ginger per cup, this tea may gently soothe the stomach. As an alternative to fresh ginger, which in Germany usually comes from Asia and contains little gingerol, you can use wild Amazonian ginger from Ecuador. It contains up to 2.5 times the active compounds.

4.2. Dosage and practical tips

Here is how to use ginger to support digestion:

• Dosage: 1–5 g fresh ginger a day (about 1–2 tsp grated) or 0.5–1 g dried. More than 5 g may irritate the stomach.
• Everyday use:
  • Stir grated ginger into soups or rice—it may support fat digestion.
  • Chew a small piece of raw ginger (about 1 g) if you feel nauseous—quick and effective.
  • Sip warm ginger water (2–3 slices in 400 ml) throughout the day.
• Note: Start with small amounts, especially if you have a sensitive stomach, and avoid ginger on an empty stomach if you are prone to heartburn.

Regular, moderate use is better than large portions—your stomach will thank you.

5. Limitations and cautions: when ginger may upset your stomach

Ginger may support digestion, but it is not right for every stomach.

 In some cases it may do more harm than good. Here we explain when to be cautious and how to avoid unpleasant surprises.

• Irritation from excessive amounts: More than 5 g of fresh ginger a day may cause heartburn or stomach cramps. An NIH review warns of these effects, particularly for sensitive stomachs.
• Worsening gastritis: If you have gastritis or ulcers, ginger may increase irritation. Its pungent compounds may then have the opposite effect, so gentler alternatives may be preferable.
• Diarrhoea in people who are sensitive to it: While ginger may soothe mild diarrhoea, it can trigger an excessive gut response in some people. This often happens with high doses or when ginger is eaten raw.
• Interactions with medicines: Ginger may affect stomach medicines (such as antacids) or increase the effects of blood thinners. Talk to your doctor if you take medicines regularly.

In short, ginger may help, but it is no cure-all. Listen to your stomach and adjust the amount to what you tolerate.

6. Conclusion: ginger as a natural digestive aid?

Does ginger really help with digestion?

Yes, in moderation: it speeds up gastric emptying, stimulates enzymes and can soothe the gut.

Studies show that ginger tea can ease nausea and relieve mild diarrhoea—a gentle aid for the stomach. 

For everyday use, ginger is a practical option: 1–5 g a day, for example as tea or in food, may support digestion without risk.

Listen to your body and avoid ginger if you have gastritis.
