Citrus (mixed), which typically refers to various species and parts of citrus fruits like lemon, orange, lime, and grapefruit, has a longstanding place in traditional medicine systems for supporting digestive health, including the relief of belching (eructation). Traditional remedies often recommend citrus peels, extracts, or juices to aid digestion and alleviate symptoms such as bloating, gas, and belching. The rationale in folk medicine is that citrus components—especially the bitter compounds in the peel—can stimulate gastric secretions and promote motility in the digestive tract, helping to move trapped gas and reduce belching.

However, scientific evidence specifically supporting the use of citrus for belching is limited. While some studies have explored the digestive effects of citrus flavonoids and essential oils, most focus on general gastrointestinal health or dyspepsia, not belching specifically. The evidence base consists largely of traditional use, anecdotal reports, and small studies that do not directly address belching as an isolated symptom. Therefore, while citrus is traditionally used for this purpose and may have mild digestive benefits, robust clinical trials validating its effectiveness for belching are lacking. Overall, the justification for using mixed citrus for belching is rooted in traditional practice rather than strong scientific support.
