Ginger tea is one of the most effective drinks for relieving indigestion, backed by solid evidence that it speeds up the rate at which food leaves your stomach. But it’s not the only option. Several other beverages can calm an upset stomach, and a few common drinks will make things worse. The best choice depends on what type of discomfort you’re dealing with.
Ginger Tea: The Strongest Option
Ginger contains a compound called gingerol that directly improves gastrointestinal motility, which is the speed at which food moves through your digestive system. When food sits in your stomach too long, you get that heavy, bloated, uncomfortable feeling. Ginger encourages efficient digestion so food doesn’t linger. This makes it especially useful after a large meal or when you feel overly full.
You can make ginger tea by steeping fresh sliced ginger root in hot water for 10 to 15 minutes, or use a store-bought ginger tea bag. Ginger in normal food-level amounts is safe for most people. If you want something faster, even flat ginger ale made with real ginger (check the label) can provide mild relief, though the sugar content makes fresh tea a better choice.
Fennel Tea for Bloating and Cramps
Fennel tea has been used for centuries to treat gas, bloating, and stomach cramps. Its essential oil contains a compound called trans-anethole that relaxes smooth muscle in the gut, which is why fennel infusions are a traditional remedy even for colicky babies. If your indigestion feels more like trapped gas or abdominal cramping than general fullness, fennel tea is worth trying. Steep crushed fennel seeds in boiling water for five to ten minutes, strain, and sip slowly.
Peppermint Tea: Helpful but With a Catch
Peppermint relaxes the smooth muscle throughout your digestive tract, which can ease cramping and that tight, uncomfortable feeling in your stomach. However, that same muscle-relaxing effect extends to the valve between your esophagus and stomach. If your indigestion involves acid reflux or heartburn, peppermint can actually make it worse by allowing stomach acid to travel upward more easily.
If your symptoms are mostly in your stomach (fullness, nausea, cramping) rather than your chest or throat (burning, sour taste), peppermint tea is a good option. If you get heartburn regularly, skip it.
Plain Warm Water
Sometimes the simplest option works. Warm water on its own can help move things along. Research on fluid temperature and digestion found that warm drinks (around 60°C, or about 140°F) increase the frequency of stomach contractions compared to cold drinks. More stomach contractions means your digestive system is actively working to process food. You don’t need anything fancy. A cup of warm water sipped slowly after a meal can ease mild discomfort.
Baking Soda Water for Quick Relief
If your indigestion is more of a burning, acidic feeling, dissolving half a level teaspoon of baking soda in four ounces of water creates a basic antacid. It neutralizes stomach acid on contact and can bring fast, temporary relief. Make sure the baking soda is fully dissolved before drinking.
There are firm limits on how much you should use. Adults under 60 should not exceed six half-teaspoon doses in 24 hours, spaced at least two hours apart. Adults over 60 should stop at three doses per day. This is a quick fix, not a daily habit. Overuse can disrupt your body’s acid balance.
A Herbal Blend Worth Knowing About
A European herbal preparation called Iberogast (sometimes labeled STW-5) combines nine plant extracts and has been studied specifically for functional digestive complaints. In clinical trials, patients experienced a 76% reduction in symptom scores during treatment, and roughly 88% of both patients and physicians rated the results as good or very good. It’s available over the counter in many countries and can be added to warm water. If single-herb teas aren’t doing enough, this combination approach may be more effective.
What About Apple Cider Vinegar?
Apple cider vinegar is one of the most popular home remedies you’ll find recommended online, but the evidence isn’t there. Harvard Health Publishing notes that no research published in medical journals supports using apple cider vinegar for heartburn or indigestion. The theory behind it, that low stomach acid causes reflux and vinegar corrects this, oversimplifies how the digestive valve actually works. Drinking something acidic when your stomach is already irritated can make discomfort worse. Stick with options that have stronger evidence behind them.
Drinks That Make Indigestion Worse
Knowing what to avoid matters as much as knowing what to drink. Three categories of beverages are common indigestion triggers:
- Carbonated drinks expand your stomach with gas. A stretched stomach puts pressure on the valve at the top, pushing acid upward and encouraging reflux.
- Alcohol relaxes the same valve, giving acid a clear path into your esophagus. This is especially likely after a large meal, when your stomach is already full.
- Excess caffeine is a less obvious trigger. A single cup of coffee in the morning is usually fine, but multiple caffeinated drinks throughout the day can set off symptoms.
If you’re reaching for a drink because your stomach already hurts, avoid all three. Opt for warm ginger or fennel tea instead, or plain warm water if nothing else is available.
Matching the Drink to Your Symptoms
The type of indigestion you’re experiencing determines the best drink. If you feel uncomfortably full after eating, ginger tea is your best bet because it speeds up stomach emptying. If you’re dealing with gas and bloating, fennel tea targets those symptoms directly by relaxing cramped intestinal muscles. If you have a burning sensation in your chest or throat, baking soda water provides the fastest neutralization of acid, and you should avoid peppermint and citrus drinks entirely. For general mild discomfort, warm water is surprisingly effective and always safe.
