Rating (out of 5): 2

Aerva lanata, commonly known as mountain knotgrass, has a history of use in traditional medicine systems such as Ayurveda and Siddha. In these traditions, it is employed for a variety of ailments, including digestive problems like gas and bloating. Folk remedies often utilize the whole plant or its decoctions as a mild diuretic and for soothing gastrointestinal discomfort. The rationale for its use for gas and bloating is primarily based on its reputed carminative and anti-inflammatory properties, as documented in ethnobotanical surveys and traditional pharmacopeias.

However, there is limited scientific evidence specifically validating its efficacy for gas and bloating. Most studies on Aerva lanata focus on its diuretic, antiurolithiatic, and antimicrobial effects rather than its impact on digestive symptoms such as flatulence or abdominal distension. While some phytochemical studies indicate the presence of saponins and flavonoids that could potentially influence gut motility or inflammation, direct clinical or preclinical studies on gas and bloating are lacking. Thus, current support for its use in addressing these digestive issues remains largely traditional, with a low evidence rating due to the absence of rigorous modern research.
