Rating (out of 5): 2

Perilla (Perilla frutescens) is an herb widely used in traditional East Asian medicine and cuisine. Its leaves and seeds have a long history of use in China, Korea, and Japan for a variety of gastrointestinal complaints, including gas and bloating. Traditional practitioners have recommended perilla for its purported carminative (gas-relieving) properties, and it appears in classical herbal formulations aimed at digestive comfort. These uses are largely based on empirical observations and centuries of anecdotal reports rather than systematic clinical studies.

Modern proprietary extracts such as "benegut perilla" are often standardized for certain active components (like rosmarinic acid or flavonoids), purportedly to enhance these traditional benefits. While laboratory and animal studies have demonstrated that perilla extracts can modulate gut motility and may reduce intestinal inflammation or hypersensitivity, direct evidence in humans—especially regarding gas and bloating—is sparse. A few small clinical studies suggest potential benefits for mild digestive discomfort, but these are limited by sample size, methodology, and lack of replication.

Therefore, the use of perilla for gas and bloating is primarily justified by tradition, with modest and emerging (but not definitive) scientific support. The overall quality of evidence is low to moderate, meriting a rating of 2 on the provided scale.
