Source of validity: Traditional
Rating (out of 5): 2

Anise (Pimpinella anisum) has a long history of use in traditional medicine systems, particularly in Mediterranean, Middle Eastern, and Asian cultures, to support digestion and relieve symptoms of indigestion such as bloating, gas, and mild stomach upset. Traditional texts and herbal compendia have described anise seeds as carminative—meaning they help expel gas from the digestive tract and ease discomfort. The seeds are often included in after-meal mixtures or teas in many cultures for this reason.

Scientific research investigating anise’s effectiveness for indigestion is limited, but some studies point to mild benefits. The essential oil of anise contains compounds such as anethole, which have demonstrated antispasmodic and carminative effects in laboratory and animal studies. A few small clinical trials have examined herbal mixtures containing anise, fennel, and other carminative herbs in relieving functional dyspepsia (indigestion), with some positive results. However, these studies do not isolate the effects of anise alone, and high-quality, large-scale clinical trials are lacking.

Overall, while there is a strong basis for the use of anise in traditional remedies for indigestion, and some preliminary scientific evidence for its benefits, the supporting evidence is not robust. Thus, the use of anise for indigestion is primarily justified by tradition, with minor scientific support, reflected in the moderate evidence rating.
