Iberogast, also known as STW5, is a liquid formulation of nine herbs used for functional dyspepsia and irritable bowel syndrome. A proprietary blend, it was developed in Germany in 1961 and is available (without prescription) in other countries. Named after the genus (Iberis) of one of its ingredients, it is also claimed to possess anti-inflammatory, antioxidative and free radical–inhibiting properties as well as the ability to reduce gastric acid secretion.[1]
