Ephedra
Ephedra is a genus of plants that includes several species known for their medicinal properties. Traditionally, it has been used in herbal medicine to treat respiratory issues, such as asthma and bronchitis, due to its natural stimulant effects. The active compounds in Ephedra, particularly ephedrine, can help open airways and improve breathing.
However, Ephedra has also been associated with health risks, especially when used in high doses or for weight loss. It can cause side effects like increased heart rate, high blood pressure, and anxiety. As a result, the use of Ephedra in dietary supplements has been banned in some countries, including the United States.
