Ephedra Overview
Ephedra, also known as ma huang, is a plant species in the family Ephedraceae, which is native to Asia and parts of North America. It has been used traditionally in herbal medicine for centuries to treat a variety of conditions, including respiratory problems, allergies, and obesity.
Ephedra contains a number of active compounds, including ephedrine and pseudoephedrine, which are stimulants that affect the central nervous system. The stimulant compounds in ephedra compounds have been used in a number of over-the-counter and prescription medications, including decongestants and weight loss supplements.
While ephedra and related stimulant compounds are still available in a number of over-the-counter medications, such as the inhaler Primatene Mist, and Bronkaid Caplets, it is banned for use in dietary supplements.
Ephedra was once an extremely popular ingredient in dietary supplements for weight loss, but it was linked to a number of serious adverse effects, including increased blood pressure, heart palpitations, stroke, and even death. As a result, the use of ephedra and ephedra-containing products were banned or restricted in many countries.
