Peppermint, ginger, fennel, caraway and chamomile are the best-studied herbs for bloating and indigestion. Most work by relaxing the muscles of the gut (antispasmodic or “carminative” action) or by speeding up stomach emptying. A cup of herbal tea after meals is a simple, low-risk way to use them, while persistent or severe symptoms always deserve a medical check.
Key takeaways
- Carminative herbs help release trapped gas and ease cramping.
- Peppermint oil has strong evidence for IBS; ginger speeds stomach emptying.
- A peppermint–caraway oil combination is one of the most studied herbal treatments for functional dyspepsia.
- Fennel, caraway and anise seeds can be chewed after meals, as is traditional in India.
- See a doctor for weight loss, blood in stools, difficulty swallowing or persistent change in bowel habits.
How do digestive herbs work?
Herbs that ease bloating and indigestion fall into a few overlapping groups:
- Carminatives – aromatic herbs rich in essential oils (peppermint, fennel, caraway, anise) that relax smooth muscle and help expel gas.
- Prokinetics – herbs that speed up stomach emptying, such as ginger.
- Bitters – bitter herbs (gentian, dandelion, artichoke) that stimulate saliva, stomach acid and bile, traditionally taken before meals.
- Demulcents – mucilage-rich herbs (marshmallow root, slippery elm) that coat and soothe the lining of the gut.
9 herbs for better digestion
| Herb | Main action | Best for | How to use |
|---|---|---|---|

| Ginger | Prokinetic, anti-nausea | Nausea, sluggish digestion | Fresh ginger tea, 1–2 cups |
| Fennel | Carminative | Bloating, wind, infant colic (traditional) | Chew ½ tsp seeds or brew tea |
| Caraway | Carminative | Bloating, fullness | Seeds in tea or cooking |
| Chamomile | Antispasmodic, calming | Stress-related indigestion | Tea after meals |
| Artichoke leaf | Choleretic (bile) | Fatty-meal indigestion | Extract capsules |

| Marshmallow root | Demulcent | Irritated stomach lining | Cold infusion |
| Turmeric | Anti-inflammatory | Functional dyspepsia | In food with black pepper |
Peppermint
Peppermint oil is recommended in UK and US clinical guidance for IBS. The tea is gentler but useful after meals, unless you have reflux. Read peppermint tea benefits.
Ginger
Ginger speeds up the rate at which the stomach empties, helping that heavy, over-full feeling, and it is one of the best-evidenced natural remedies for nausea. See our ginger tea guide.
Fennel
Fennel seeds contain anethole, which relaxes the gut. In India and Pakistan, a small handful of sugar-coated fennel seeds (mukhwas) is offered after meals. Fennel tea is a traditional remedy for wind and colic, though fennel products should not be given to babies without medical advice.
Caraway and peppermint together
A combination of peppermint and caraway oils has been tested in several German trials for functional dyspepsia, showing significant improvements in pain, pressure and fullness compared with placebo.
Chamomile
Chamomile relaxes the gut and the mind – useful when stress and digestion are linked. See chamomile tea benefits.
Artichoke leaf
Artichoke leaf extract increases bile flow, which helps the body digest fats. Trials have reported improvement in indigestion symptoms. Avoid it with gallstones or bile duct obstruction.
Dandelion root
A classic bitter tonic. Roasted dandelion root makes a coffee-like drink that may gently stimulate appetite and digestion, although human studies are scarce.
Marshmallow root and slippery elm
These mucilaginous herbs form a soothing gel. Make a cold infusion by soaking 1–2 teaspoons of marshmallow root in cold water for several hours. Take them two hours apart from medicines, as they may slow absorption.
Turmeric
A Thai trial found turmeric capsules worked as well as omeprazole for functional dyspepsia. More in turmeric and curcumin.
A simple after-dinner digestive tea
Mix 1 tsp crushed fennel seeds, ½ tsp caraway seeds and a few fresh peppermint leaves (or 1 tsp dried). Pour over 250 ml boiling water, cover, steep for 10 minutes and strain. Lightly crushing the seeds releases their oils.
Lifestyle habits that matter more
- Eat slowly and chew well to reduce swallowed air.
- Limit fizzy drinks, chewing gum and sugar alcohols (sorbitol, xylitol).
- Try reducing high-FODMAP foods such as onions, garlic and beans if you have IBS – ideally with a dietitian.
- Take a short walk after meals; gentle movement helps gas move through.
When to see a doctor
Book an appointment with your GP or doctor if you have unexplained weight loss, difficulty swallowing, blood in your stools or vomit, persistent change in bowel habit, or bloating that lasts more than three weeks – especially if you are over 50, as persistent bloating can occasionally signal ovarian or bowel conditions.
