Peppermint and ginger tea are the two most effective herbal teas for bloating and constipation — peppermint relaxes the gut wall to relieve trapped gas, while ginger stimulates digestive motility to get things moving. Several other teas offer useful complementary benefits, each working through a slightly different mechanism.
1. Peppermint Tea — Best for Gas and Cramping
Peppermint’s menthol compounds act as calcium channel blockers in the smooth muscle of the GI tract, relaxing the intestinal wall and reducing painful spasms. This antispasmodic effect makes it particularly effective for the cramping and trapped gas associated with bloating. Research published in the Journal of Gastroenterology confirms peppermint’s role in reducing IBS symptoms including bloating.
How to brew: Steep 1–2 teaspoons of dried peppermint leaves in 250ml of just-boiled water for 10 minutes. Cover the cup during steeping to keep the volatile oils in the tea, not the air above it.
How often: Up to 3 cups per day, ideally between meals rather than directly with food.
Who should avoid it: People with GERD or acid reflux — peppermint relaxes the lower oesophageal sphincter, which can worsen reflux symptoms. Also avoid if you have a hiatus hernia.
2. Ginger Tea — Best for Slow Digestion and Nausea-Related Bloating
Gingerols and shogaols in ginger act as prokinetics — they speed up gastric emptying and stimulate the movement of food through the intestine. This makes ginger particularly effective when bloating is caused by sluggish digestion rather than just gas. A 2011 study published in the European Journal of Gastroenterology and Hepatology found ginger significantly accelerated gastric emptying compared to placebo.
For a detailed guide on getting the most from ginger, including the differences between fresh and dried root, see our article on ginger tea for bloating and gas.
How to brew: Simmer 2–3 slices of fresh ginger root in 300ml of water for 10 minutes, or steep 1 teaspoon of ground ginger in boiling water for 5 minutes.
How often: 2–3 cups per day. Most effective when drunk 20–30 minutes before meals to prime digestion.
Who should avoid it: People on blood-thinning medications (ginger has mild anticoagulant effects). Avoid at high doses (over 4g daily). Caution in the two weeks before surgery.
3. Fennel Tea — Best for Gas and Bloating After Meals
Fennel contains anethole, the compound responsible for its distinctive anise flavour, which relaxes GI smooth muscle and acts as a carminative — it helps expel trapped gas and reduce the discomfort of bloating. The practice of chewing fennel seeds after meals is a traditional digestive aid across Indian and Mediterranean cultures, with good clinical basis. For more on fennel’s digestive applications, see our guide to fennel seeds for digestive problems.
How to brew: Crush 1–2 teaspoons of fennel seeds lightly (to release the volatile oils), then steep in boiling water for 10 minutes. Strain before drinking.
How often: 2–3 cups per day, particularly after meals.
Who should avoid it: Pregnant women should avoid medicinal amounts of fennel (culinary amounts in food are fine). Those with oestrogen-sensitive conditions should consult a doctor first.
4. Dandelion Root Tea — Best for Constipation and Fluid Retention Bloating
Dandelion root acts as a gentle bitter tonic — it stimulates bile production and liver function, which supports digestion and can gently relieve constipation. Dandelion leaf (different from the root) acts as a natural diuretic, which can help with the water retention component of bloating. The German Commission E approves dandelion root for digestive complaints including bloating and flatulence.
How to brew: Steep 2–3 teaspoons of roasted dandelion root in 300ml of boiling water for 10–15 minutes. The roasted version has a pleasantly coffee-like flavour.
How often: 1–3 cups per day, before meals for digestive support.
Who should avoid it: People with ragweed allergy (same Asteraceae family cross-reaction as chamomile). Those with gallstones or bile duct obstruction — dandelion stimulates bile flow and can worsen these conditions.
5. Chamomile Tea — Best for Inflammation-Related Bloating
Chamomile has well-documented anti-inflammatory properties alongside its antispasmodic effects. For bloating driven by gut inflammation — such as after a food intolerance reaction — chamomile can help calm the intestinal lining while also reducing cramping. The ESCOP (European Scientific Cooperative on Phytotherapy) supports chamomile for gastrointestinal inflammation and spasmodic complaints.
How to brew: Steep 2–3 teaspoons of dried chamomile flowers in 250ml of hot water (just under boiling) for 5–10 minutes, covered.
How often: 3 cups per day during acute digestive discomfort.
Who should avoid it: Those with ragweed or Asteraceae allergy. Caution with blood thinners.
6. Licorice Root Tea — Best for Soothing GI Irritation
Deglycyrrhizinated licorice (DGL) is well-supported for soothing the GI lining and reducing inflammation. Whole licorice root tea is effective for bloating related to gastritis or irritation, but must be used with care because glycyrrhizin — the compound removed in DGL products — can raise blood pressure and deplete potassium at high doses. DGL-form supplements are the safer option for regular use.
How to brew: Use 1 teaspoon of dried licorice root per cup. Steep for 5 minutes only — longer steeping extracts more glycyrrhizin.
How often: Limit to 1 cup per day and do not use for more than 4 weeks continuously.
Who should avoid it: People with high blood pressure, heart disease, kidney disease, low potassium, pregnancy. Anyone on medications that affect blood pressure or electrolytes.
7. Senna Tea — Short-Term Use Only for Constipation
Senna is a potent stimulant laxative that increases intestinal contractions to relieve constipation. It works reliably but is in a different category from the teas above — it’s a medical intervention, not a gentle digestive support. Senna tea is appropriate for short-term relief (up to one week at a time) but should not be used regularly. Chronic use leads to dependency, electrolyte imbalance, and can damage the intestinal lining over time.
Use senna tea only when: Other gentler approaches haven’t worked, you’re comfortable accepting it as a short-term laxative (not a long-term digestive aid), and ideally after checking with a pharmacist or doctor if you have other health conditions.

Frequently Asked Questions
Can I drink herbal teas for bloating every day?
Most digestive herbal teas — peppermint, ginger, fennel, chamomile — are safe to drink daily for extended periods. Licorice root and senna are exceptions and should not be used continuously. If bloating is a daily problem despite using herbal teas, this warrants investigation to identify the underlying cause (food intolerance, IBS, gut microbiome issues).
How quickly do herbal teas relieve bloating?
Peppermint and ginger work relatively quickly — most people notice relief within 20–40 minutes. Fennel works similarly. Dandelion root and chamomile have slower, more cumulative effects. Senna takes 6–12 hours to produce a laxative effect.
When to See a Doctor
Herbal teas are appropriate for occasional digestive discomfort. See a doctor if bloating is severe or persistent (lasting more than two weeks), if it’s accompanied by significant weight loss, blood in the stool, pain that wakes you from sleep, or if you have a family history of bowel conditions. These warrant testing to rule out coeliac disease, IBD, or other conditions that won’t respond to herbal teas alone.
