Several herbal teas can help ease acid reflux symptoms, with ginger, chamomile, licorice root, and fennel being the most well-supported options. The key is choosing caffeine-free varieties, since caffeine can loosen the valve between your stomach and esophagus and make reflux worse. Here’s what works, what to skip, and how to get the most out of each cup.
Ginger Tea: The Strongest Evidence
Ginger is one of the best-studied herbal options for upper digestive symptoms. Its main benefit for reflux is that it speeds up gastric emptying, the rate at which food moves out of your stomach and into your small intestine. When food sits in the stomach too long, pressure builds and acid is more likely to push upward. A study published in the World Journal of Gastroenterology found that ginger cut the stomach’s half-emptying time from about 16 minutes to 12 minutes compared to placebo, a roughly 25% improvement. Ginger also increased contractions in the lower part of the stomach, helping move things along.
For reflux specifically, this means less time with a full, pressurized stomach after meals. Fresh ginger slices steeped in hot water for 10 to 15 minutes make a simple tea. Start with a small piece (about a half-inch slice) if you’re new to it, since too much ginger on an empty stomach can cause its own brand of heartburn in some people.
Chamomile Tea: Soothing Irritated Tissue
Chamomile works differently from ginger. Rather than speeding digestion, it targets the irritation that reflux leaves behind. Chamomile contains compounds with anti-inflammatory properties that may reduce inflammation in the esophagus and calm the discomfort that comes from repeated acid exposure. If your symptoms include a raw, burning sensation in your throat or chest, chamomile is a reasonable choice.
It’s also naturally caffeine-free and mildly sedating, which makes it a good option before bed. Nighttime reflux is common because lying down removes gravity’s help in keeping acid down, and chamomile’s relaxing effect can do double duty by easing both the physical irritation and the difficulty sleeping that often comes with it.
Licorice Root Tea: Building a Protective Barrier
Licorice root helps reflux through a different mechanism: it stimulates mucus production in the stomach and esophagus. This extra mucus acts as a physical barrier between your tissue and stomach acid, giving damaged areas a chance to heal while reducing the burning sensation. A 2014 study confirmed that a processed form of licorice promoted this mucus activity.
One important caveat: standard licorice root contains a compound called glycyrrhizin that can raise blood pressure and lower potassium levels with regular use. Look for “deglycyrrhizinated” licorice (often labeled DGL) products, which have this compound removed. DGL licorice root tea or chewable tablets before meals are the safest way to get the benefits without the risks. If you have high blood pressure or take heart medications, this distinction matters even more.
Fennel Tea: Reducing Stomach Pressure
Fennel tea has a surprisingly sophisticated effect on the stomach. Research published in Neurogastroenterology & Motility found that it relaxes the upper portion of the stomach while simultaneously increasing motility in the lower portion. This combination is ideal for reflux: relaxing the upper stomach reduces the internal pressure that pushes acid upward, while boosting movement in the lower stomach helps food exit more efficiently.
Fennel is also traditionally used for gas and bloating, both of which increase abdominal pressure and can worsen reflux. If your reflux tends to flare after meals and comes with a bloated, overfull feeling, fennel tea after eating is worth trying. Use crushed fennel seeds (about one teaspoon per cup) steeped for 10 to 15 minutes.
Marshmallow Root and Slippery Elm Tea
Both of these herbs contain a substance called mucilage that turns into a slippery gel when mixed with water. This gel physically coats the lining of the esophagus and stomach, creating a protective layer over inflamed tissue. Think of it as a natural, temporary bandage for your digestive tract. Slippery elm in particular has a long history of use for acid reflux, and the coating effect can provide fairly quick relief from the burning sensation.
These teas have a thicker, slightly slimy texture that takes some getting used to. Marshmallow root is milder in flavor. Both work best when sipped slowly so the gel has time to coat the esophagus on the way down, rather than being gulped quickly.
The Peppermint Question
Peppermint tea is one of the most common recommendations for digestive problems, but it has a complicated reputation when it comes to reflux. For years, the standard advice has been to avoid it because menthol was thought to relax the valve at the bottom of the esophagus, allowing acid to escape upward. Recent research tells a more nuanced story.
A study published in the journal Dysphagia found that menthol infused directly into the esophagus did not significantly affect valve pressure or esophageal contractions in either healthy subjects or people with diagnosed reflux disease. The researchers concluded that peppermint’s tendency to trigger symptoms likely comes from direct stimulation of sensory nerves in the esophagus rather than any actual loosening of the valve. In practical terms, this means peppermint may cause a burning or irritating sensation in people whose esophagus is already inflamed, even though it isn’t mechanically making reflux worse.
If your reflux is mild and peppermint tea doesn’t bother you, there’s no strong reason to stop drinking it. But if your esophagus is already irritated, peppermint’s sensory effects can mimic or amplify the feeling of heartburn. It’s best treated as a personal tolerance issue rather than a blanket rule.
How to Brew Tea for Reflux
Brewing method matters more than most people realize. For most herbal teas, water between 200 and 212 degrees Fahrenheit steeped for about five minutes works well. Root-based teas like licorice, ginger, and fennel benefit from a longer simmer of 10 to 15 minutes to fully release their active compounds. If you’re using green tea (which does contain some caffeine), brew at a lower temperature, around 160 to 180 degrees, for just one to three minutes. Cold-brewing green tea is another option that reduces both bitterness and caffeine content.
Temperature of the tea when you drink it also matters. Very hot beverages can irritate an already inflamed esophagus. Let your tea cool to a comfortably warm temperature before drinking.
What to Add (and What to Avoid)
Honey is a safe and potentially beneficial sweetener for reflux-friendly teas. It has a mildly thick consistency that may coat the esophagus, and it avoids the issues that come with processed sugar, citrus-based flavorings, or cream. A teaspoon stirred into warm tea is a reasonable amount.
Avoid adding lemon or other citrus, which can lower the pH of your tea and directly irritate the esophagus. Milk or cream can trigger more acid production in some people, though small amounts are generally tolerated. Artificial sweeteners are neutral for reflux but can cause bloating in some people, which indirectly worsens symptoms by increasing abdominal pressure.
Teas to Avoid With Reflux
Any tea with significant caffeine content can worsen reflux. Black tea, standard green tea in large quantities, and chai tea (which combines black tea with spices) are the most common culprits. Caffeine relaxes the lower esophageal sphincter and increases stomach acid production, a combination that directly promotes reflux. If you’re not ready to give up caffeinated tea entirely, keep it to one cup earlier in the day rather than after meals or before bed.
Citrus-based herbal teas like lemon, orange, or hibiscus are also problematic. Hibiscus in particular is quite acidic and can irritate the esophagus even though it’s caffeine-free and often marketed as a health tea.
