The story of the word

The plant genus Ephedra carries a Greek name Pliny had used for horsetail, built from upon and seat, for a plant that perches on something. Nagai Nagayoshi isolated the alkaloid from ma huang in 1885, and it became the first widely used asthma drug before it became a banned stimulant. The ἕδρα in it is the same seat as in cathedral, which is named for a bishop's chair.
