Fennel has a warm nature and possesses functions of warming the stomach to dispel cold, regulating qi, and relieving pain. It can help alleviate symptoms such as stomach pain, abdominal distension, and indigestion caused by cold stomach. The fennel oil contained in fennel can stimulate the gastrointestinal nerves and blood vessels, promote secretion of digestive juices, enhance gastrointestinal motility, and aid in improving gastric digestive function.
