How It Works
The active constituents in anise, particularly the terpenoid anethole, are contained in its volatile oil. The volatile oil gives the plant a delightful flavor and has been combined with other less pleasant tasting medicinal herbs to offset their taste. The oil is also antispasmodic, helping to relieve intestinal gas and spasmodic coughs.14 Anise has been combined with cathartic laxatives to help reduce the spasmodic cramping they can cause.15 It may also have modest antiparasitic actions and has been recommended by some practitioners to treat mild intestinal parasite infections.16 Anethole has been documented to have phytoestrogen activity in test tubes and animals;17 the relevance of this to humans is unknown. No clinical trials have been conducted to support any of these uses, though anise is approved for use by the German Commission E for relieving coughs and indigestion.18
How to Use It
Three grams (1/2 tsp) of the seeds can be used three times per day to treat indigestion. To make a tea, boil 2 to 3 grams (1/2 tsp) of crushed seeds in 250 ml (1 cup) of water for ten to fifteen minutes, keeping the pot covered. Three cups of this tea can be drunk per day. It has been recommended to combine approximately 0.5 ml anise volatile oil with 4 oz (120 ml) tincture of anise and then take 10 to 30 drops (1/2 to 1.5 ml) of this mixture three times daily for coughs.19 The volatile oil can also be inhaled (by placing it in a vaporizer or in a steaming bowl of water) to help relieve a cough.20
