Synopsis

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

Sweet Orange (Citrus sinensis) has traditionally been used in various cultures as a remedy for digestive disturbances, including belching (eructation). In Traditional Chinese Medicine and some folk medicine systems, orange peel—particularly dried bitter orange peel, but also sweet orange—has been employed to "regulate qi," reduce bloating, and ease symptoms of indigestion, which can include belching. The aromatic compounds and essential oils found in sweet orange peel are believed to promote the movement of digestive gases and support normal gastrointestinal function.

However, the evidence base for these uses is largely historical and anecdotal. There are very few clinical studies that specifically investigate the efficacy of sweet orange or its extracts in treating belching. Most available scientific research on Citrus sinensis focuses on its antioxidant and anti-inflammatory properties, with minimal emphasis on its direct effects on digestive complaints such as belching. Some in vitro and animal studies suggest that citrus peels may have spasmolytic or carminative effects, but these findings have not been robustly validated in human trials.

In summary, the use of sweet orange for belching is justified primarily by traditional use, with limited scientific support. The strength of evidence is low, and more research is needed to establish its efficacy for this specific indication.
