Ephedra

A genus of 40 shrubs and some vines that are native to dry regions of Eurasia, north Africa and the America, with rush-like, mostly green branches that resembles horsetails.
The leaves are tiny and scale like. The cone like flowers are small ( to 0.5 inches ) and are followed by fleshy red berries. A tasty medicinal tea was made from the branches by the Mexican Native Indians. The Tea is made from dried or fresh chopped stems boiled for 2 minutes. Animals do not eat Ephedra.
They prefer full sun and sandy soil and make excellent rock garden plants and for groundcover. They can be reproduced from seed, layering, separating suckers from the parent and by dividing the clumps.

  1. The most well known sort of ephedrine is a type of stimulant based on the plant ephedra extract and has been utilized in Chinese medicine for significantly more than 5, 000 years for treating asthma, colds, hay fever and more. Referred to as ephedra sinica in Chinese, this natural stimulant increases heart rate, stimulates brain activity, constricts blood vessels and opens the bronchial tubes.
