Uses
Main article: Ephedra

Ephedra distachya is used to relieve acute muscular and rheumatic pains (when it is called teamsters' tea), as a stimulant, and in the cardio tonics in Ayurveda. It is sometimes identified with the legendary drug soma, as described in the Avesta and the Rig Veda, the respective ancient sacred texts of the Zoroastrian and Hindu faiths.

Ephedrine, an alkaloid, is obtained from its dried branches and is used as a stimulant, often to control asthma. It was isolated from the plant by Nagayoshi Nagai in 1885. All parts of the plant contain up to 3% ephedrine.[4]
