Etymology: Pilocarpine is named after its plant source rather than after a person or an event. It is an alkaloid extracted from the leaves of South American shrubs of the genus Pilocarpus, and the name joins that genus name to the chemical suffix "-ine," which marks many alkaloids and basic compounds. The genus name itself is built from Greek elements, "pilos" meaning felt or cap and "karpos" meaning fruit, a reference to the way the plant's fruit is enclosed in a felt-like covering. The drug's name therefore records a botanical fact: the substance was named for the plant, and the plant for its fruit. Pilocarpine is used in medicine to constrict the pupil and lower pressure inside the eye, which is why the word now usually appears in eye-care contexts.
