Synopsis

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

Lemon has been traditionally used to support the stomach and digestive system in several cultures. Historical records from Ayurveda and traditional European herbal medicine cite lemon and its juice as being beneficial for digestion, used to alleviate symptoms of indigestion, bloating, and heartburn. The citric acid in lemon is thought to stimulate gastric juice production, which may aid in the breakdown of food. Additionally, lemon water is a common home remedy for nausea and to help "cleanse" the digestive tract, although these uses are largely anecdotal.

Scientific studies supporting these traditional uses are limited. While lemons are a source of vitamin C and antioxidants, there is little direct clinical evidence that lemon or lemon juice provides specific benefits to the stomach or digestive health beyond what would be expected from general hydration and vitamin C intake. Some in vitro studies suggest that lemon extracts may have mild antimicrobial effects, which could theoretically support gut health, but these findings have not been robustly demonstrated in humans. Overall, the use of lemon for stomach support is primarily justified by tradition rather than strong scientific evidence.
