Get medical help if arrange medical assessment if gas symptoms are persistent or troublesome, change suddenly, affect daily activities, or occur with abdominal pain, bowel changes, or unexplained weight loss.
Self-care guide
Intestinal gas
Belching, passing gas, or gas-related abdominal pressure that becomes bothersome or more frequent than usual.
Step 1 · First-line care
What to do first
Some gas is normal. For bothersome symptoms, start with reducing swallowed air by eating more slowly, avoiding gum, straws and fizzy drinks when they are triggers, trying smaller meals, and tracking foods or drinks that reliably increase symptoms. Treat identified causes such as lactose intolerance, constipation, or IBS rather than relying on indefinite symptom treatment. Traditional herbal options are secondary supportive choices.
Step 2 · Safety
When to get medical help
Extra caution: Children, pregnancy, breastfeeding, people with reflux or biliary disease, and people with significant food restriction or suspected malabsorption need preparation- and cause-specific review. Avoid broad elimination diets without a clear trigger or professional guidance.
Step 3 · Optional ingredient support
For relief now
These options have been reviewed for evidence and key safety concerns.
Anise
Traditional short-term relief of mild indigestion complaints that include flatulence using aniseed preparations that follow medicinal-product directions.
How it is used: Use a clearly identified aniseed medicinal preparation or tea that follows product or monograph directions. Do not infer a therapeutic dose from ordinary culinary use.
What does this evidence mean?
Aniseed has recognized traditional medicinal use for mild digestive complaints including flatulence. The recognition is based on long-standing use rather than strong modern clinical trials.
Evidence may apply to one specific form of an ingredient — a capsule, extract, cream, or tea — and to a particular amount. Recipes and everyday foods may not match the form or amount that was studied.
Caraway
Traditional short-term relief of flatulence and related mild digestive discomfort using caraway-fruit preparations.
How it is used: Use a clearly identified caraway-fruit medicinal preparation that follows product or monograph directions. If symptoms persist beyond about two weeks or change meaningfully, look for an underlying cause.
What does this evidence mean?
Caraway fruit has recognized traditional medicinal use for digestive problems such as flatulence. This is a traditional-use claim, not proof that culinary caraway reliably treats excess intestinal gas.
Evidence may apply to one specific form of an ingredient — a capsule, extract, cream, or tea — and to a particular amount. Recipes and everyday foods may not match the form or amount that was studied.
Fennel
Traditional short-term relief of mild spasmodic gastrointestinal complaints that include flatulence using sweet-fennel-fruit preparations.
How it is used: Use a clearly identified sweet-fennel-fruit preparation that follows product or monograph directions. Culinary fennel can remain part of normal food use without inheriting a medicinal-dose claim.
What does this evidence mean?
Sweet fennel fruit has recognized traditional use for mild spasmodic digestive complaints including flatulence. This does not establish that ordinary food amounts or any fennel tea are clinically proven treatments.
Evidence may apply to one specific form of an ingredient — a capsule, extract, cream, or tea — and to a particular amount. Recipes and everyday foods may not match the form or amount that was studied.
Peppermint
Traditional short-term relief of digestion-related symptoms including flatulence using peppermint-leaf preparations.
How it is used: Keep peppermint leaf and peppermint oil separate. A broad intestinal-gas claim should not borrow IBS evidence from enteric-coated peppermint oil or treat essential oil as interchangeable with leaf tea.
What does this evidence mean?
Peppermint leaf has recognized traditional use for digestion-related complaints such as indigestion and flatulence. This is distinct from the stronger, condition-specific evidence for enteric-coated peppermint oil in IBS.
