Ephedraceae is a family of plants that includes the genus Ephedra, which consists of shrubs and small trees. These plants are primarily found in arid and semi-arid regions around the world. They are characterized by their jointed stems and scale-like leaves, which help them conserve water in dry environments. Members of the Ephedraceae family are known for producing alkaloids, such as ephedrine, which have stimulant properties. Due to these compounds, some species have been used in traditional medicine and as dietary supplements. However, their use can also pose health risks, leading to regulatory scrutiny in various countries.
