Ephedra viridis, known by the common names green Mormon tea, green ephedra, and Indian tea, is a species of Ephedra. It is indigenous to the Western United States, where it is a member of varied scrub, woodland, desert, and open habitats. It grows at 900–2,300 metres (3,000–7,500 ft) elevations.
The drug ephedrine, an antidepressant and decongestant, is made from this and other Ephedra species. A tea can be made by boiling the stems, whence the common name, "green Mormon tea".
