Ephedraceae

Ephedraceae (pronounced eh-feh-druh-see-ee) is a family of gymnosperm shrubs, known as the Ephedra family. The family is small, containing only one genus, Ephedra, with about 40 species.

Etymology

The name Ephedraceae is derived from the genus name Ephedra, which in turn comes from the Greek word "ephedros," meaning "sitting upon," in reference to the plant's habit of growing on rocks and other elevated places.

Description

Members of the Ephedraceae family are typically shrubby plants that inhabit arid and semi-arid regions. They are characterized by their jointed stems and scale-like leaves. The plants produce small, cone-like structures instead of flowers, a characteristic of gymnosperms. The seeds are borne in small, berry-like cones that turn red or orange when mature.

Distribution

Ephedraceae is distributed worldwide, but most species are found in the Americas, southern Europe, and Asia. They are typically found in desert or semi-desert environments, and are well-adapted to these harsh conditions.

Uses

Many species within the Ephedraceae family have been used for medicinal purposes. The most well-known of these is probably Ephedra sinica, also known as Ma Huang, which has been used in traditional Chinese medicine for thousands of years. The plant contains ephedrine, a stimulant that can treat conditions such as asthma, nasal congestion, and low blood pressure.
