Anise (Pimpinella anisum) seeds are a highly prized carminative and expectorant spice containing rich volatile oils, dominated by trans-anethole. Trans-anethole is absorbed systemically and excreted partly through the lungs, where it directly stimulates the bronchial glands to secrete thin mucus, while relaxing smooth bronchial muscles to quiet dry coughs. In the gut, it relaxes intestinal sphincters to ease abdominal bloating and cramps.
