Officinal



Officinal is a term applied in medicine to drugs, plants and herbs, which are sold in a chemist or druggist shop, and to medical preparations of such drugs, et cetera, as are made in accordance with the prescriptions authorized by a pharmacopoeia. Not to be confused with the word "official". The classical Latin officina meant a workshop, manufactory, laboratory, and in medieval Latin was applied to a general storeroom. It thus became applied to a shop where goods were sold rather than a place where things were made.

In botanical nomenclature, the specific epithet officinalis derives from a plant's historical use in pharmacology.
