Can Herbal Tea Cause Heartburn? | Tea And GERD Facts

Some herbal teas may cause or worsen heartburn, particularly those with peppermint or spearmint.

You probably think of herbal tea as a gentle, soothing drink. A steaming mug of chamomile before bed, a ginger infusion after a heavy meal, maybe a peppermint tea to settle your stomach. It’s the kind of drink that’s supposed to help you relax, not add to your troubles. So when you take a sip and feel that familiar burn creeping up your chest, it can feel confusing or even frustrating.

The truth is more nuanced than a simple yes or no. While many herbal teas are well-tolerated and may even soothe digestive discomfort, certain ingredients—particularly peppermint and spearmint—can trigger or worsen heartburn in some people. The effect depends on the specific herb, your individual sensitivity, and whether you already have a condition like GERD. This article breaks down which teas to avoid, which to try, and what the science really says.

How Herbal Teas Interact With The Esophagus

The key player in heartburn is the lower esophageal sphincter (LES), a ring of muscle at the bottom of your esophagus that acts like a one-way valve. When it’s working well, it lets food and drink pass into your stomach and then closes tight to prevent stomach acid from splashing back up.

Certain compounds in food and drink can cause the LES to relax too much. When that happens, even if you feel fine otherwise, acid can creep upward and cause that familiar burning sensation behind your breastbone. For people who already have a weak LES due to GERD, even a small amount of relaxation can trigger symptoms.

Menthol, the active compound in peppermint and spearmint, is one substance thought to encourage this unwanted relaxation. While many people enjoy mint tea for its refreshing taste and digestive-aid reputation, the same mechanism that helps soothe gas and bloating may also contribute to acid reflux in some individuals.

Why The Mint Misconception Sticks

The idea that mint helps digestion is deeply ingrained. For generations, peppermint tea has been recommended for upset stomachs, nausea, and general digestive discomfort. And in many ways, that reputation is earned—menthol can help relax smooth muscle tissue in the gut, which may relieve cramping and bloating.

But here’s the catch. The same muscle-relaxing effect that helps lower intestinal cramping can also relax the LES. For someone with a tendency toward acid reflux or GERD, this creates an opening—literally—for stomach acid to travel upward. That’s why a mint tea that seems to calm your stomach might still leave you with a burning throat an hour later.

Common herbal teas and their potential effects on heartburn:

• Peppermint tea: May relax the LES due to menthol content; often cited as a common trigger for heartburn symptoms, especially in those with GERD.
• Spearmint tea: Contains a similar compound profile to peppermint, though with less menthol; still a potential trigger for some people.
• Chamomile tea: Generally well-tolerated and may actually help reduce stress, a known contributor to acid reflux. Most experts consider it safe.
• Ginger tea: Often recommended for nausea and digestive comfort; widely regarded as a safe option that may help soothe the digestive tract.
• Licorice root tea: Traditionally used for digestive health; generally not associated with worsening reflux, though it has different considerations for blood pressure.

If you’re prone to heartburn, paying attention to which herbal teas you choose and how you feel afterward can help you identify your personal triggers. The herbal tea you drink may be the culprit, but it’s not the only one—how you brew it and when you drink it matter too.

What The Research Says About Tea And GERD Risk

A noteworthy study on the topic is a meta-analysis of observational studies published in the peer-reviewed journal BMC Gastroenterology. That analysis looked at the link between general tea consumption and the risk of developing GERD. The finding was clear: across the pooled data, tea drinking had no significant association with overall tea and GERD risk.

That seems reassuring, but there’s an important caveat. The study included all types of tea—black, green, oolong, and herbal—without isolating the specific effects of mint-based infusions. Because the analysis combined all tea drinkers, a potential triggering effect from peppermint tea could have been diluted by the larger number of green and black tea drinkers who experienced no issues.

So the research doesn’t suggest that tea in general causes heartburn. Rather, it indicates that the risk is ingredient-specific. For the average person without a history of acid reflux, herbal tea is unlikely to cause problems. For those with sensitive digestion or existing GERD, the mint varieties deserve extra scrutiny.

This table summarizes the typical associations, but individual responses can vary. If you have a known sensitivity to mint, even a small amount in a tea blend might be enough to trigger symptoms.

How To Enjoy Herbal Tea Without The Burn

If you love herbal tea but worry about heartburn, you don’t need to give it up entirely. A few simple adjustments can make a big difference. Start by identifying the safest choices for your body and paying attention to the context around your tea-drinking habits.

1. Swap mint for a gentler option. Chamomile, ginger, or rooibos are less likely to relax the LES and may even support digestion. They’re good starting points for people with reflux.
2. Check the label on blends. Many “herbal” teas are blends that may contain small amounts of peppermint or spearmint along with other herbs. Read the ingredient list if you’re unsure.
3. Drink it at the right time. Avoid drinking large amounts of any tea close to bedtime or right after a heavy meal when reflux is more likely. Wait an hour or two after eating.
4. Skip the sweeteners. Adding sugar, honey, or other sweeteners can increase the acidity of the beverage and may worsen symptoms for some people.

These strategies are simple, but they address the most common triggers. If you find that even gentle teas cause problems, consider whether other factors—portion size, temperature, or timing—might be the real issue.

Other Herbal Teas Worth Trying For Reflux

Beyond the common choices, there are a few less-heralded options that some people find helpful. Slippery elm tea, made from the inner bark of the tree, is sometimes suggested as a soothing beverage for the esophagus. The mucilage in the bark can coat the lining of the throat and stomach, which may provide temporary comfort.

Decaffeinated herbal teas, without mint, are also a practical option. Caffeine itself can relax the LES, so removing that variable helps narrow down your triggers. As Gaviscon’s guide on herbal tea cause heartburn notes, caffeinated and decaffeinated drinks like tea can cause heartburn, and choosing plain water or herbal teas without mint is recommended instead.

It’s worth repeating that individual responses vary widely. What triggers a flare-up in one person may be perfectly fine in another. Keeping a simple food diary—noting when you drink a tea and whether you experience any symptoms afterward—can be more useful than any general list of rules.

The Bottom Line

Herbal tea can cause heartburn, but it depends entirely on the ingredients. Peppermint and spearmint teas are the most common offenders due to their potential to relax the lower esophageal sphincter. Most other herbal infusions—chamomile, ginger, rooibos, licorice root—are generally well-tolerated and may even help soothe mild digestive discomfort. A meta-analysis found no link between general tea drinking and GERD risk, suggesting the effect is ingredient-specific rather than universal.

If heartburn persists after switching to a gentler tea, your primary care doctor or a gastroenterologist is the right person to discuss your specific symptoms and rule out other underlying causes of reflux. They can also help you sort out whether the timing of your tea or the meal before it is playing a bigger role than the tea itself.
