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.
Bromocriptine Overview
-
Bromocriptine (Parlodel) is used to treat symptoms of hyperprolactinemia (high levels of a natural substance called prolactin in the body) including lack of menstrual periods, discharge from the nipples, infertility (difficulty becoming pregnant) and hypogonadism (low levels of certain natural substances needed for normal development and sexual function). Bromocriptine (Parlodel) may be used to treat hyperprolactinemia caused by certain types of tumors that produce prolactin, and may shrink these tumors. Bromocriptine (Parlodel) is also used alone or with other treatments to treat acromegaly (condition in which there is too much growth hormone in the body) and Parkinson's disease (PD; a disorder of the nervous system that causes difficulties with movement, muscle control, and balance). Bromocriptine (Cycloset) is used with a diet and exercise program and sometimes with other medications to control blood sugar levels in people with type 2 diabetes (condition in which the body does not use insulin normally and therefore cannot control the amount of sugar in the blood). Bromocriptine (Cycloset) is not used to treat type 1 diabetes (condition in which the body does not produce insulin and therefore cannot control the amount of sugar in the blood) or diabetic ketoacidosis (a serious condition that may develop if high blood sugar is not treated). Bromocriptine is in a class of medications called dopamine receptor agonists. It treats hyperprolactinemia by decreasing the amount of prolactin in the body. It treats acromegaly by decreasing the amount of growth hormone in the body. It treats Parkinson's disease by stimulating the nerves that control movement. The way bromocriptine works to treat diabetes is not known.
