Summary
The traditional use of ephedra is to stop "leakages" caused by lack of energy and vigor. It stops sweating at night, fluid buildup in the lung, and weak pulse causing "dribbles" of arterial circulation. All of these effects are helpful in colds, flu, and asthma. Most members of this genus contain various medicinally active alkaloids (but notably ephedrine) and they are widely used in preparations for the treatment of asthma and catarrh. The stems are a pungent, bitter, warm herb that dilates the bronchial vessels whilst stimulating the heart and central nervous system. The stems are also antidote, diaphoretic, diuretic, pectoral, vasoconstrictor and vasodilator, and they are used internally in the treatment of asthma, hay fever and allergic complaints.
