Ephedrine ( /ɨˈfɛdrɪn/ or /ˈɛfɨdriːn/; not to be confused with ephedrone) is a sympathomimetic amine commonly used as a stimulant, appetite suppressant, concentration aid, decongestant, and to treat hypotension associated with anaesthesia.
Ephedrine is similar in structure to the (semi-synthetic) derivatives amphetamine and methamphetamine. Chemically, it is an alkaloid derived from various plants in the genus Ephedra (family Ephedraceae). It works mainly by increasing the activity of noradrenaline on adrenergic receptors. It is most usually marketed in the hydrochloride and sulfate forms.
In Traditional Chinese Medicine, the herb má huáng (麻黄, Ephedra sinica) contains ephedrine and pseudoephedrine as its principal active constituents. The same is true of other herbal products containing extracts from some of the other Ephedra species.
Ephedrine exhibits optical isomerism and has two chiral centres, giving rise to four stereoisomers. By convention the enantiomers with opposite stereochemistry around the chiral centres (1R,2S and 1S,2R) are designated ephedrine, while pseudoephedrine has same stereochemistry around the chiral carbons (1R,2R and 1S,2S).

Watch you watching me & I catch you watching me & you empty inside me, just to watch me bleed. I see your footsteps bend in my mind as shadows stomp their way down my spine. I try to run away, I can't hide. The demons that I see are inside, watch you watching me & I catch you watching me& you empty inside me, just to watch me bleed. You say my life is a lie, you can see with violence. Show me reality, I feel you look at me, I feel your hands on me, I know your love but I'm not gonna cry. Good God, can't you fucking see? Good God, is this a fucking dream? Good God while I lie & bleed. Good God what'd you do to me? I can see empty in me. I lie & bleed all I can see & you step on me again & your back on me again & you empty inside me just to watch me bleed & when I close my eyes you're all I see, I can't take your face from my dreams, I feel you look at me, I feel your hands on me. I know your love but I'm not gonna cry
