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.
Fluoxymesterone Overview
-
Fluoxymesterone is used to treat symptoms of low testosterone in adult men who have hypogonadism (a condition in which the body does not produce enough natural testosterone). Fluoxymesterone is used only for men with low testosterone levels caused by certain medical conditions, including disorders of the testicles, pituitary gland, (a small gland in the brain) or hypothalamus (a part of the brain) that cause hypogonadism. Fluoxymesterone is also used to stimulate puberty in men with delayed puberty. Fluoxymesterone may also be used alone or along with other medications in certain women with breast cancer that has spread to other parts of the body and can not be removed with surgery. Fluoxymesterone is in a class of medications called androgenic hormones. It works by supplying testosterone to replace the testosterone that is normally produced naturally in the body. Testosterone is a hormone produced by the body that contributes to the growth, development, and functioning of the male sexual organs and typical male characteristics. When used to treat breast cancer, testosterone works by blocking the release of estrogen to stop or slow the growth of breast cancer..
