Dealing with occasional digestive issues? Want to work something into your routine to help keep your gut humming along nicely? Tea might be the answer. There are several herbal teas that may support gut health or provide relief from occasional digestive concerns like nausea, gas, bloating, and heartburn.

“Peppermint tea and ginger tea provide extra fluids and soothing warmth without caffeine,” says Patsy Catsos, RDN, who specializes in irritable bowel syndrome (IBS) and is the owner of Advanced Nutrition, LLC, in New London, New Hampshire. Ginger may be particularly useful for reducing nausea, and peppermint may help ease IBS symptoms.

 

Ashley Oswald, RDN, the gut health–focused founder of Oswald Digestive Clinic in Minneapolis, also recommends drinking fennel tea, which may be particularly helpful for gas, bloating, and heartburn.

Our team of editors, writers, and product testers recently tried dozens of teas from over 10 well-known tea brands. Based on the results of our testing, and insights from Catsos and Oswald, we've narrowed down a long list of prospects to these eight gut-friendly picks. Here are the best teas for digestion in 2026.

Our Picks for the Best Teas for Digestion

When to Consult Your Doctor

Tea is safe to drink for most people. But herbal tea ingredients may affect some medications. If you're taking any prescription medications, it's a good idea to speak with your doctor before you start using herbal tea specifically for digestive health.

If you have ongoing digestive issues, it's best to talk with your doctor or a dietitian who specializes in gut health.

Best Chai Mix

Chai.com Glow Chai

Pros

  • No steeping time required
  • Contains no added sweetener
  • Smooth texture and taste

Cons

  • May not contain enough ginger to support digestive health
  • Not appropriate for people with nut allergies

Key Specs

  • Format: Powdered mix
  • Ingredients: Turmeric, black peppercorn, cardamom, cinnamon, cloves, ginger, nutmeg
  • Caffeinated: No
  • Organic: Yes
Glow Chai is a caffeine-free chai mix that contains ginger, which may help improve nausea and assist with the movement of food through your digestive tract.

 It also contains turmeric, a spice with the antioxidant curcumin, which may help improve digestive symptoms and gut microbiome health.

 Cinnamon, cardamom, and cloves give it a comforting, warm flavor.

Our editorial director, Simone Scully, says this chai is smooth without being overpowered by the ginger and pepper. “I like this one with and without milk,” she says.

The chai comes in a resealable pouch, and it also comes with a reusable wooden scoop. To prepare it, you simply mix the powder into your preheated liquid of choice, such as milk, water, or a plant-based milk. To improve turmeric absorption, it's best to choose a liquid that contains some fat, like low fat or whole-fat milk, or soy, oat, or nut-based milks.

This mix contains no sweetener, so you can customize the sweetness level to your preference. Since it requires no steeping time, this mix may also be a good option for people who want something that's quick and easy.

We do want to note that this tea may not contain enough ginger per serving to have a noticeable effect for everyone. Also, it's manufactured in a facility that also handles tree nuts, so do not use it if you have a tree nut allergy.

kombucha ginger lemon

Best Ready-to-Drink

Health-Ade Kombucha Ginger Lemon

Pros

  • Source of probiotics
  • Available in several flavors
  • Convenient, ready-to-drink bottles or cans

Cons

  • Strong ginger flavor may be overwhelming for some people
  • Pricier than other teas

Key Specs

  • Format: Ready-to-drink bottles or cans
  • Ingredients: Kombucha, ginger juice, lemon juice concentrate, live active cultures (Bacillus coagulans)
  • Caffeinated: No
  • Organic: Yes

Health-Ade Kombucha Ginger Lemon combines the probiotic benefits of fermented tea (kombucha) with the digestive health benefits of ginger in a convenient, ready-to-drink bottle or can. I've personally tried this product, and while I find the ginger flavor a bit overwhelming, it's a flavorful, fizzy, and refreshing way to get a quick dose of probiotics and ginger with or after a meal.

Regular kombucha intake may help relieve digestive symptoms, and it can positively influence microbial balance in the gut.

 

“There are many options that will suit your taste buds,” says writer Raki Swanson. “Health-Ade is taking drinks we normally consume — soda and kombucha — and adding healthy ingredients with a bunch of flavors."

Health-Ade Kombucha is available in several flavors, including some that contain nausea-relieving ginger.

 One drawback, though, is that this kombucha is significantly more expensive than most loose-leaf tea, tea bags, or tea mixes, at over $4 per bottle.

Best Ginger Tea

Traditional Medicinals Ginger Aid

Pros

  • Certified organic
  • Not too spicy, thanks to additional ingredients
  • May help with nausea relief

Cons

  • Tea bags give you less control over the strength of your tea
  • Contains stevia, so it’s pre-sweetened

Key Specs

  • Format: Tea bags
  • Ingredients: Ginger rhizome, blackberry leaf, stevia leaf, lemon myrtle leaf
  • Caffeinated: No
  • Organic: Yes

Traditional Medicinals Ginger Aid is a balanced blend of ginger, lemon myrtle, and blackberry leaf. I’ve found that the key flavor in the blend is definitely the ginger, but it's not as overwhelmingly gingery as teas that contain only ginger.

Although tea bags give you less control over the strength of your tea than loose-leaf tea, you can steep it for a shorter or longer period of time to adjust the sharpness of the flavor. This organic tea also contains stevia as a sweetener, so it may not appeal to people who prefer to control the level of sweetness themselves.

Ginger is well-known for helping relieve nausea, so this tea is a great option for pregnant women who are battling morning sickness or for anyone who deals with occasional bouts of nausea.

Technically speaking, there's very little research on the effects of ginger tea, specifically. But in our research, we noted that many people appreciate ginger tea for its calming effects on their digestion. Many people who drink this tea regularly say they enjoy it after their evening meal to help settle their stomachs before bedtime.

ginger mint tea

Best for Nausea

Celestial Seasonings TeaWell Organic Ginger Mint

Pros

  • Mild ginger-and-mint flavor
  • Certified organic
  • Spearmint may support overall wellness

Cons

  • Not available in loose-leaf form
  • Some customers say this tea tastes weak

Key Specs

  • Format: Tea bags
  • Ingredients: Green rooibos leaf, dandelion root, European elderberry fruit, Asian ginseng root, spearmint, ginger, moringa
  • Caffeinated: No
  • Organic: Yes

According to the experts we spoke with, ginger use is excellent for supporting digestion and relieving nausea. This tea from Celestial Seasonings combines ginger with spearmint, green rooibos tea, dandelion root, elderberry fruit, and ginseng root.

This caffeine-free blend provides antioxidants and polyphenols that could support gut microbial balance.

 Research shows that spearmint may provide several benefits for digestion, gut health, and overall health. But well-designed human studies on the benefits of spearmint are lacking.

In my opinion, spearmint has a milder flavor than peppermint, so this is a good choice for people who don't like a strong minty flavor or smell. We noted during our research that many people drink this tea on a daily basis. Some like to have it after meals to help with digestion or to ease stomach upsets. But some customers also say that this tea is weak and that they needed two tea bags and a long steep time to get an acceptable flavor. This tea is only available in tea bags.

peppermint tea

Best Peppermint Tea

Teapigs Peppermint Tea

Pros

  • Larger leaves and high-quality tea bags
  • Pure peppermint leaves are the only ingredient
  • May help ease digestive issues

Cons

  • Not organic
  • Some say its peppermint flavor isn’t strong enough

Key Specs

  • Format: Tea bags, loose leaf
  • Ingredients: Peppermint leaves
  • Caffeinated: No
  • Organic: No

Teapigs Peppermint Tea is a single-ingredient tea that contains only large pieces of dried peppermint leaves. Peppermint may help relieve IBS symptoms and abdominal pain.

But it’s important to note that peppermint oil is the most heavily researched form of peppermint, and there's no direct evidence that peppermint tea would have the same effect.

 Anecdotally, though, peppermint tea is a soothing favorite.

Teapigs is one of my personal favorite brands of tea, and I’m not alone. “I like the open, pyramid-shaped bags that allow the leaves the space they need to move around,” says editor Olivia Campbell, who tested this tea. “The company also uses much larger leaves and pieces than most bagged tea, giving it a better and stronger flavor.”

This tea isn't organic, and according to our research, it isn't as minty as some prefer.

fennel tea

Best for Gas and Bloating

Traditional Medicinals Fennel Tea

Pros

  • Certified organic
  • May help with gas and bloating
  • Widely available

Cons

  • Not available in loose leaf
  • Some people don't enjoy the licorice-like taste of fennel

Key Specs

  • Format: Tea bags
  • Ingredients: Fennel fruit
  • Caffeinated: No
  • Organic: Yes
This organic fennel tea from Traditional Medicinals may be particularly helpful for gas and bloating, says Oswald. Fennel tea works by speeding up gastric motility, or the rate at which food moves through your digestive tract.

 Fennel has a taste that's similar to licorice — one that people tend to either love or hate.

I'm a fan of Traditional Medicinals as a brand, and I've tried this fennel tea before. While I personally don't like the taste of fennel enough to drink the tea regularly, I can attest that Traditional Medicinals is an excellent, affordable brand. It's available in most grocery stores, too. It's only available in tea bags, though. So if you prefer loose-leaf tea, you'll need to find a different brand.

lemon ginger tea

Best With Probiotics

Twinings Lemon Ginger With Probiotics

Pros

  • Contains heat-resistant probiotics
  • Contains ginger to support digestive relief
  • Balanced flavor

Cons

  • Not organic
  • Requires 4 cups per day for suggested daily dose of probiotics

Key Specs

  • Format: Tea bags
  • Ingredients: Ginger, natural lemon and ginger flavor with other natural flavors, turmeric, cinnamon, clove, licorice root, B. coagulans Gbi-30 6086
  • Caffeinated: No
  • Organic: No
Twinings Lemon Ginger With Probiotics is a tea made with a special probiotic strain that is able to resist boiling water temperatures. Probiotics are live, active bacterial strains that can help support gut health by improving the balance and health of beneficial microbes in your digestive tract.

According to Twinings, each cup of this tea contains approximately 250 million colony-forming units (CFU) of probiotics. It also contains ginger to help with nausea relief and offers a balanced flavor all around.

Campbell tested some Twinings teas. "They offer consistent, reliable flavors at a budget-friendly price," she says. This tea isn't organic and also contains added natural flavor. If you're trying to avoid non-organic ingredients or added flavors, it won't be the right fit for you.

For a full daily dose of 1 billion CFU, you'd need to drink four cups of this tea daily. This can get expensive fairly quickly, though. so it may not be practical unless you already drink this much tea regularly.


matcha

Best Green Tea

The Republic of Tea Super Green Tea Digestion

Pros

  • Lower in FODMAPs than other leaf teas
  • Contains ginger to support nausea relief
  • Nice packaging

Cons

  • Not available in loose leaf
  • No string tags on tea bags

Key Specs

  • Format: Tea bags
  • Ingredients: Turmeric root, green tea leaf, ginger root, Japanese matcha leaf, black pepper fruit, natural flavor
  • Caffeinated: Yes
  • Organic: Yes
Green tea is a naturally caffeinated leaf tea that can be good for digestive health. Catsos says it's lower in carbs called FODMAPs (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols) than black tea. FODMAPs can be difficult for people with IBS to digest properly. So low-FODMAP options are important choices for people with this condition.

Also, caffeine can be helpful for speeding up the movement of food through your digestive tract. So drinking green tea may be particularly suitable for people who struggle with constipation or bloating.

In addition to green tea, this blend contains ginger, turmeric, and black pepper. Ginger is a particularly helpful addition to digestive-health blends, because it may help relieve nausea and improve gut motility.

 Likewise, turmeric may offer some digestive benefits as well, particularly for people with IBS and irritable bowel disease.

“There's nothing really not to like about these teas,” Scully says of the brand. “I think they're all very nicely balanced and flavorful, and the prices seem reasonable. I like that all of these teas come in tins that you wouldn't mind leaving out on a shelf.”

This tea isn't offered in loose-leaf form, and the Republic of Tea tea bags don't have string tags on them. That can make them slightly less convenient to dispose of once your tea is done steeping.

Other Noteworthy Teas We Considered

Our team tried several different tea brands and individual teas. Here are a few others that didn't make our final ranking, but that may be worth your consideration:

Leaves of Leisure Autumn Breeze Herbal Tea contains ginger as a main ingredient, along with other warm and comforting ingredients like cinnamon. “A lot of the tea came through the mesh bag,” says Campbell. “It would be better to either have a tighter-woven bag or loose-leaf tea.”

Palais des Thes L'Herborist No. 52 and No. 119 are two tea blends created especially for digestion. While we didn't try these teas specifically, Scully tried several other blends from Palais des Thes. “I think these are all very nice teas that are tasty and feel special,” she says. “Overall, I like that most of these teas come with tins that I can store them in.”

Traditional Medicinals Cup of Calm isn't particularly marketed as a digestive tea, but it contains chamomile and peppermint, along with other floral ingredients like lavender. I love the taste of this tea; it's much more subtle than a pure peppermint tea, and it may be worth trying if you don't like an overwhelming minty flavor.

Nepal Tea Collective Chamomile Ginger is a high-quality loose-leaf tea that contains ginger as a key ingredient. “The vacuum-sealed bags are not resealable in any way,” Campbell says.

How We Chose the Best Teas for Digestion

To choose the best teas for digestion, we first spoke with two registered dietitians — both experts in digestive health — about which teas were the best, how they worked, and how to use them.

  • Patsy Catsos, RDN, owner of Advanced Nutrition, LLC, in New London, New Hampshire
  • Ashley Oswald, RDN, founder of Oswald Digestive Clinic in Minneapolis

We also dug into recent research on the topic of tea for gut health, and the specific ingredients that Catsos and Oswald recommend.

Our team of editors, writers, and product testers recently tested teas from more than 10 reputable, well-known tea brands. We were able to recommend products from brands with high-quality, flavorful teas at a variety of price points.

I'm also a regular tea drinker. Although I don't currently seek out teas for digestion, I have leaned heavily on ginger and peppermint teas during my pregnancies to help with nausea. I've personally tried several of the picks on our list as well.

What to Look for When Buying Teas for Digestion

If you want to start a new tea habit to help support gut health or improve digestion, here are a few things to consider when choosing a tea:

  • Ingredients Certain teas may be more helpful for digestion than others. Catsos and Oswald recommend peppermint and ginger tea.

     

     Fennel tea, chamomile tea, and green tea may also be good choices for some people. Some teas may also contain added ingredients, like probiotics or prebiotics.
  • Caffeine Content Leaf teas — like green, black, and white teas — naturally contain caffeine. Herbal teas, including peppermint and ginger, do not. Caffeine can speed up the movement of food through your digestive tract. “This can be a plus or a minus for digestion, depending on the person,” says Catsos. It may be helpful for people with constipation, but it could also irritate the gut in other people.

  • Tea Form This is a matter of personal preference. Do you like tea bags or loose-leaf tea? Would you prefer a powder that you can simply mix in hot water? Are ready-to-drink options more convenient for you?
  • Flavor To make tea drinking a habit, you'll have to find one that you enjoy. Some teas can have very strong flavors. Ginger tea, for example, may taste too strong or spicy for some people, especially if it's steeped for a long time. Fennel tea is reminiscent of licorice, which not everyone enjoys.

What Are the Best Teas for Digestion and How Do They Work?

There are several teas that may offer digestive health benefits. Here are the teas that Catsos and Oswald recommend:

  • Peppermint Tea Oswald says that peppermint is a very soothing choice for gut health for many people. She cautions that it may cause heartburn for some people, so it may not be right for people who have acid reflux issues. Catsos says peppermint is low in FODMAPs, so it's a good choice for people with IBS as well.
  • Ginger Tea This is a go-to for nausea. “It's a traditional remedy for nausea and has antioxidant and anti-inflammatory properties that might explain how it works,” says Catsos. She recommends it for people who have IBS as well.
  • Fennel Tea Oswald recommends fennel tea as a good option for people with acid reflux, gas, or bloating. “Its gentle, calming effect on the digestive tract helps relax intestinal muscles and reduce digestive discomfort,” she says.

  • Chamomile Tea Chamomile tea is a natural source of fructans, which are prebiotic fibers that may help feed healthy gut bacteria.

     Catsos warns that fructans are FODMAPs, so they may be irritating to people with IBS.
  • Green Tea Catsos says that green tea is the best leaf tea for digestive health, particularly for people with IBS, because of its lower FODMAP content. Unlike the herbal teas listed above, green tea naturally contains some caffeine.

Are There Any Risks or Side Effects of Teas for Digestion?

Most teas are gentle enough that there are few risks or side effects. But herbal teas may contain ingredients that can interact with prescription medications. Be sure to speak to your doctor if you have any concerns about the potential effects of herbal tea on medication.

“A small number of people find peppermint products cause heartburn,” adds Catsos. Regarding regular teas — including green, black, and white teas — she says that caffeine can have unique effects on digestion. “Some may find that caffeine is a useful part of their bowel routines, helping with regularity. Others report that caffeine is too strong for them and causes diarrhea.”

“Additions to tea should also be considered to avoid digestive issues,” she says. She recommends that people with IBS consider using lactose-free milk products in their tea. She also emphasizes that sweeteners should be limited and that a small amount of honey or maple syrup is the best sweetener option for people with digestive concerns.


FAQs

What tea is good for bloating and IBS?
Catsos says the best teas for bloating and IBS are peppermint, ginger, and green teas. These are lowest in FODMAPs, which may make them more gentle on the digestive system for people with IBS.
Some teas contain added probiotics, like Twinings Lemon Ginger With Probiotics. Also, kombucha is a type of fermented tea beverage that is a natural source of probiotics.
Many teas provide potential health benefits. Depending on what you add to your tea, your health needs, and your current caffeine content, two to three cups of herbal or traditional tea per day can be a healthy addition to your routine.
