Central nervous system: it is used in epilepsy, hysteria and insanity

Respiratory system: The leaf extract has been used for treatment of bronchitis and asthma for many centuries. It relieves cough and breathlessness. The leaves of the plant contain the alkaloid vasicine (C11H12N2O), which is responsible for the small but persistent bronchodilatation, and an essential oil which is chiefly responsible for the expectorant action. The leaves and roots contain other alkaloids, vasicinone, vasicinolone and vasicol, which may contribute to the bronchodilatory effect through anticholinergic action on the vagal innervation of the bronchii. The bronchodilation effect is considerably increased after atropine
