A white, odorless substance that comes from certain plants or can be made in a lab. It is used to help treat breathing problems like asthma and allergies.

Ephedrine is derived from 'ephedra' (from Greek 'ephedra', meaning a type of plant) and '-ine' (a suffix used in chemistry to denote substances). The word refers to a compound derived from the ephedra plant, which is known for its medicinal properties.
Think of the 'ephedra' plant, which is where ephedrine comes from, and remember that '-ine' indicates it's a chemical substance derived from that plant.
