Fact

Drug grinders were employed by apothecaries and chemists & druggists to prepare drug material to be used in medicinal preparations.
Drug grinding involved reducing the medicinal substance to a fine powder. This labour intensive work was normally achieved in a mortar and pestle, using a revolving, shearing action.
