When your stomach is upset, drinking a warm cup of tea is an easy way to ease the symptoms.
However, the type of tea can make a big difference.
In fact, certain varieties have been shown to treat problems such as nausea, diarrhea and vomiting.
In the rest of the article, see the 9 best teas to calm an upset stomach.
The best teas for the stomach
1. Green tea
Green tea has been extensively researched for its many potential health benefits.
Historically, it has been used as a natural remedy for diarrhea and infection with Helicobacter pylori, a strain of bacteria that can cause stomach pain, nausea and bloating.
It can also relieve other stomach problems.
For example, one study noted that green tea significantly reduced the frequency and severity of diarrhea caused by radiation therapy.
Also some studies have shown that green tea and its components also treat stomach ulcers, which can cause problems such as pain, gas and indigestion.
Note that it’s best to stick to 1-2 cups (240-475ml) per day, as – ironically – excessive intake is associated with side effects such as nausea and stomach upset due to the high caffeine content.
2. Ginger tea
Ginger tea is obtained by boiling ginger root in water.
This root can be incredibly helpful for digestive issues like nausea and vomiting.
According to one review, ginger helped prevent morning sickness in pregnant women, as well as nausea and vomiting caused by chemotherapy.
Another review noted that ginger can reduce gas, bloating, cramping and indigestion while supporting proper bowel function.
Although most of these studies looked at high doses of ginger supplements, ginger tea can provide many of the same benefits.
To make it, grate peeled ginger and soak it in boiling water for 10-20 minutes. Strain and drink as is or add a little lemon, honey or cayenne pepper.
3. Mint tea
Peppermint tea is a common choice when an upset stomach starts.
In fact, studies reveal that peppermint can relax the intestinal muscles and help relieve pain. Furthermore, studies suggest that peppermint oil reduces the duration, frequency, and severity of stomach pain in children.
This oil has even been shown to prevent nausea and vomiting associated with chemotherapy.
You can buy this tea at grocery stores or make it yourself by steeping crushed mint leaves in hot water for 7-12 minutes.
4. Black tea
Black tea boasts a number of health benefits similar to those of green tea, especially for soothing stomach aches.
It can be particularly effective in treating diarrhea quickly.
In fact, taking black tea pills can help you improve the volume, frequency, and regularity of your stools.
One study noted that black tea extract can reduce the prevalence of diarrhea by 20% in cases of E. coli infection.
Although most of the research looks at supplements, tea on its own can still help with stomach problems.
However, it is best to limit your intake to 1-2 cups (240-475 ml) per day, as excessive amounts of caffeine can cause stomach upset.
5. Fennel tea
Fennel is a plant from the carrot family with a licorice flavor.
Tea from this flowering plant is commonly used to treat a variety of ailments, including relieving stomach pain, constipation, gas and diarrhea.
Taking a fennel supplement a few days before and during your period can reduce symptoms such as nausea.
Studies also reveal that fennel extract blocks the growth of several strains of bacteria, such as harmful E. coli, and promotes proper digestion and intestinal recovery after surgery.
Try making fennel tea at home by steeping 1 cup (240 ml) of hot water with 1 teaspoon (2 grams) of dried fennel seeds.
Alternatively, you can soak the roots or leaves of the fennel plant in hot water for 5-10 minutes before straining.
6. Licorice tea
Licorice is known for its distinctly sweet, slightly bitter taste.
Many forms of traditional medicine have used this legume to soothe upset stomachs.
Multiple studies indicate that licorice helps heal stomach ulcers. An ulcer can trigger symptoms such as stomach pain, nausea and indigestion – a condition that causes stomach discomfort and heartburn.
It was pointed out that one study showed that taking 75 mg of licorice extract twice a day significantly reduced indigestion.
This tea can be bought in many supermarkets as well as online. It is often combined with other ingredients in herbal tea blends.
Note that licorice root is associated with several side effects and can be dangerous in large amounts. So stick to 1 cup (240 ml) of licorice tea a day and consult your doctor if you have health problems.
7. Chamomile tea
Chamomile tea is light, aromatic and often considered one of the most calming types of tea.
It is often used to relax the digestive muscles and naturally treat heartburn and reflux, as well as other problems such as gas, indigestion, nausea, vomiting and diarrhea.
In studies, taking 500 mg of chamomile extract twice daily reduced the frequency of chemotherapy-induced vomiting.
Chamomile extract has also been shown to prevent diarrhea.
Although these studies tested large amounts of chamomile extract, tea made from these daisy-like flowers can also ease stomach problems.
To make a tea, steep a tea bag or 1 tablespoon (2 grams) of dried chamomile leaves in 1 cup (237 ml) of hot water for 5 minutes.
8. Basil tea
Also known as tulsi, holy basil is a powerful herb that has long been valued for its healing properties.
Although not as common as other teas, it is an excellent option for soothing an upset stomach.
Multiple studies have found that holy basil protects against stomach ulcers, which can cause a wide range of symptoms, including stomach pain, heartburn, and nausea.
In fact, in one study, holy basil reduced the incidence of stomach ulcers and completely healed existing ulcers within 20 days of treatment.
Holy basil tea bags can be found in many health stores as well as online. You can also use dried basil powder to make your own fresh cup.
9. Mint tea
Like peppermint, peppermint can help relieve digestive problems.
It boasts a compound called carvone that helps reduce muscle contractions in the digestive tract.
In one study, people with irritable bowel syndrome (IBS) were given a product containing mint, coriander and lemon balm along with anti-diarrhea or constipation medication.
Those who took the peppermint product reported significantly less abdominal pain, discomfort, and bloating than those in the control group.
However, the supplement contained more ingredients than just mint.
Also, studies have noted that mint can block the growth of several strains of bacteria that can contribute to foodborne illness.
Mint tea is easy to make at home. Simply boil 1 cup (240 ml) of water, remove from heat and add a handful of mint leaves. Keep for 5 minutes, then strain and serve.
