This shrub is broom-like, resembling horsetail grass. The jointed green stems and branches of some species reach the height of 7 feet, although most are smaller. Two or three scale-like leaves grow at joints in stem and branches. Male and female cones appear on different plants, the male cones have yellow pollen sacs. Found in arid areas of the Northern Hemisphere, especially in deserts of the southwest.
It is most commonly used as a pleasant beverage. Steep for 5 minutes. The whole herb is historically used as a decongestant, and stimulant to the sympathetic nervous system. Frequent use of the tea may result in nervousness and restlessness. It should only be used with medical supervision, particularly if suffering from high blood pressure, heart disease, diabetes or thyroid trouble.
