Rating (out of 5): 2

Spearmint leaf (Mentha spicata) has a long history of use in traditional medicine systems, such as those in Europe, the Middle East, and South Asia, for relieving digestive discomfort, including belching (also known as eructation). Traditionally, spearmint is believed to have carminative properties, meaning it helps to expel gas from the stomach or intestines, thereby reducing bloating and belching. Folk medicine practitioners have used infusions and teas made from spearmint leaves to soothe the digestive tract, ease stomach cramps, and decrease excessive gas.

Despite its historical use, there is limited scientific evidence specifically validating spearmint’s effectiveness for belching. Most modern research on mint species focuses on peppermint, which contains higher concentrations of menthol and has more robust clinical data supporting its use for irritable bowel syndrome and dyspepsia. Spearmint contains less menthol but is gentler on the stomach and less likely to cause reflux than peppermint, which may be why it has been favored traditionally for milder digestive complaints.

In summary, spearmint’s use for belching is primarily justified by traditional usage rather than scientific validation. While historical and anecdotal evidence supports its role as a digestive aid, direct clinical research on spearmint for belching is lacking, so its effectiveness remains largely unproven by modern standards.
