Etymology: Norpseudoephedrine is a chemist's name built from parts that each describe a chemical relationship. Its core, "pseudoephedrine," takes "pseudo-" from Greek "pseudes," meaning "false," and "ephedrine," named after the plant genus Ephedra. Ephedra's name comes from Greek roots that likely mean something like "sitting upon," a reference to the plant's growth habit. The "nor-" prefix is a chemistry convention that marks a compound with one methyl group (a CH₃ unit) removed, so the substance is a demethylated relative of pseudoephedrine. Its best-known natural source is not the decongestant plant but khat (Catha edulis), a shrub chewed for its stimulant effect in East Africa and the Arabian Peninsula. Its stereoisomer, the form known as cathine, is the compound responsible for much of khat's stimulant action.

Synonyms: cathine
