Cough anise

Expectorants are the drugs which increase the production of bronchial secretion and reduce its viscosity to facilitate its removal by coughing. Expectorants can stimulate the expulsion of respiratory secretion either directly or reflexly. Certain volatile oils of plant origin such as oil of lemon, anise, eucalyptus by steam inhalation route increase the respiratory secretion by its direct action. Another compound, guaiacol, which is obtained from wood creosote or synthetically prepared, directly increase bronchial secretion and syrup tolu (Tolu balsum) act in same way. 

Star anise essential oil, I. verum, is often used as a substitute for anise seed oil in perfumery because it shares similar chemistry. It is used in aromatherapy to help relieve coughing, colic, cramping, hiccups and indigestion. It should be used in moderation to avoid skin irritation (Rosengarten, 1969 Lust, 1974 Malcolm, 1987).
