Why it might work
Fennel seed’s volatile oil, mostly anethole with some fenchone, relaxes gut smooth muscle, which is why the seeds are chewed after meals in much of the world. In a 2025 laboratory study, brewed fennel tea relaxed the upper part of guinea pig stomach strips and strengthened contractions in the lower part, a pattern the authors link to functional dyspepsia. A tea releases only part of the seed’s oil, so the effect is gentle and unmeasured, and no human trial confirms the stomach finding. The 2,000 mg of seed can be checked on the panel; the oil content of a cup cannot.
What the trials show
One trial of fennel tea was found, and it was in surgery patients: 159 women who drank a cup made from 5 g of fennel fruit twice a day after abdominal cancer surgery passed gas about 11 hours sooner and went home about a day earlier than controls. The rest is in infants and in oil: a fennel seed oil emulsion cleared colic in 65% of 62 infants against 24% on placebo, and a curcumin and fennel oil capsule cut IBS scores by half in 121 adults. No trial tested a fennel tea bag for everyday bloating, and a bag here holds 2 g.
What the label discloses
The panel prints one organic ingredient, fennel fruit, at 2,000 mg a bag, with no sweetener, flavor or other ingredient. The brand states USDA and CCOF organic, Non-GMO and kosher status but publishes no testing laboratory or certificate. It asks for a covered 10 to 15 minute steep and up to three cups a day.

Who this tends to suit
Its symptom profile covers bloating, gas and general abdominal discomfort. It is scored for a goal of day-to-day comfort or handling meals. Whether it is the best fit for you depends on the rest of your answers — what you have already tried, what format you will take, and anything that has to be ruled out.
Where it may not fit
The label supports vegan, gluten-free, dairy-free, no added sweeteners and minimal ingredient list. If you are pregnant or breastfeeding, expect Organic Fennel Tea to be missing from your results on purpose; that decision is routed to a clinician, not made here. Like any tea, it depends on being taken as often as the label directs.
Reactions and warnings
Some reviewers dislike the strong licorice flavor, a few find the bags weak or poorly stapled, and one reports an allergic reaction. The label says not to use it with an allergy to parsley-family plants (which includes fennel and dill) and to consult a practitioner if pregnant or breastfeeding, even though the brand also lists fennel as a traditional herb for nursing mothers.
The questions that come up
Does fennel tea help with gas and bloating?
No trial of fennel tea for everyday gas or bloating exists. Amazon reviewers say it eases bloating after meals (4.7 from 1,945 ratings), and the only tea trial found was in surgery patients, where it shortened the time to first gas. Trials in colicky infants used fennel oil or herbal blends.
How much fennel is in Traditional Medicinals Fennel tea?
2,000 mg of organic fennel fruit (the seed) per tea bag, and nothing else. The tea trial found used 5 g of fennel fruit per cup.
How much does Traditional Medicinals Fennel tea cost per cup?
A 16-bag box is $7.49 on the brand’s store, about $0.47 a cup, and $6.99 on iHerb and Amazon.com, about $0.44. The brand’s 6-pack works out to about $0.44 a cup.
Is fennel tea safe, and what are the side effects?
The label says not to use it with an allergy to parsley-family plants and to consult a practitioner if pregnant or breastfeeding. Reviewers mention the licorice-like taste; one reports being allergic to it.
Fennel tea vs peppermint tea for bloating?
Neither has a trial as a tea for everyday bloating. Fennel gives a sweet, anise-like cup at 2,000 mg a bag, and peppermint tea is one herb with a menthol flavor and a heartburn caution for some people.
One check first. Traditional Medicinals sells a supplement, not a treatment, and if you are pregnant or breastfeeding the decision belongs with a doctor or pharmacist, not with this page.
