Herba Ephedrae preparations are used in the treatment of nasal congestion due to hay fever, allergic rhinitis, acute coryza, common cold, and sinusitis. The drug is further used as a bronchodilator in the treatment of bronchial asthma and has been used to aid weight loss. Use of the herb is related to its active components - ephedrine and pseudoephedrine which are potent stimulators of the sympathetic nervous system. Since overstimulation of the sympathetic nervous system my induce lethal cardiac rhythm disorders or hypertension their use can not be recommended. The interaction of the herbs with some antidepressant medication (e.g. monoamine oxidase inhibitors) may be lethal. Preparations containing ephedra are banned in the United States. Prescription only medicine: ephedrine, pseudephedrine, amphetamine, ecstasy

Nomenclature
