efedriini
Efedriini is a naturally occurring stimulant found in plants of the Ephedra genus. It is chemically related to amphetamines and acts as both a sympathomimetic agent, meaning it mimics the effects of adrenaline and noradrenaline, and a central nervous system stimulant. Historically, various Ephedra species have been used in traditional medicine for respiratory ailments, as a decongestant, and as an appetite suppressant.
In modern pharmacology, efedriini is used as a bronchodilator to treat asthma and other respiratory conditions.
