Officinalis is an adjective derived from the Latin word for "workshop", officina, and means basically "of the workshop." In Medieval Latin officina came to be applied to the storerooms of monasteries, where (among other things) medicinal herbs were kept. This led to the use of the adjective officinalis in the scientific names of a number of medically useful plants, including the marsh mallow, Althaea officinalis, and the Apothecary Rose, Rosa gallica officinalis.
