Fennel is one of the top herbs for regulating digestion. It warms and stimulates the digestive organs without irritating sensitive tissues or aggravating acid reflux. It promotes healthy appetite, helps the body release gas, and is an excellent remedy for colic and for headaches related to improper digestion. Its antispasmodic effects make it a good herb to include in blends featuring stimulant laxatives, which can cause painful cramping if not blended with more soothing digestives. Fennel’s antispasmodic action also benefits the respiratory system, calming a hacking or convulsive cough. It lends a delicious flavor and aromatic lift to herbal blends and cough syrups. It can be used as a mild diuretic and kidney cleanser, especially in combination with other kidney-specific herbs. Fennel also promotes the flow of breast milk in nursing mothers- it is often blended with fenugreek and goat’s rue for this purpose.
