Synopsis

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

Carvone is a naturally occurring monoterpene found in essential oils of various plants such as caraway and spearmint. It has been traditionally used for gastrointestinal complaints, including bloating and flatulence, due to its carminative properties. Scientifically, several studies have investigated the effects of caraway oil, with carvone as a major constituent, on functional dyspepsia and related symptoms such as belching. Some clinical trials and reviews suggest that caraway oil, often in combination with peppermint oil, can reduce symptoms like bloating, fullness, and belching by relaxing gastrointestinal smooth muscle and reducing spasms ("spasmolytic effect"). The mechanism is thought to involve modulation of calcium channels in the gut wall, leading to decreased motility and reduced gas formation.

However, while the evidence indicates a potential benefit, most studies use mixed preparations (e.g., caraway oil plus peppermint oil) rather than isolated carvone, and sample sizes are often small. The data supporting carvone specifically for belching is limited but promising, justifying a moderate evidence rating. Thus, there is scientific, albeit not robust, support for the use of carvone-containing preparations in treating belching and related dyspeptic symptoms.
