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.
Progesterone Overview
-
Progesterone is used as a part of hormone replacement therapy in women who have passed menopause (the change of life) and have not had a hysterectomy (surgery to remove the uterus). Hormone replacement therapy usually includes estrogen, which is used to treat symptoms of menopause and reduce the risk of developing certain diseases. However, estrogen can also cause abnormal thickening of the lining of the uterus and increase the risk of developing uterine cancer. Progesterone helps to prevent this thickening and decreases the risk of developing uterine cancer. Progesterone is also used to bring on menstruation (period) in women of childbearing age who have had normal periods and then stopped menstruating. Progesterone is in a class of medications called progestins (female hormones). It works as part of hormone replacement therapy by decreasing the amount of estrogen in the uterus. It works to bring on menstruation by replacing the natural progesterone that some women are missing.
