The superscription consists of the sign ℞, which consists of the letter R with an oblique dash across the final stroke. The letter R is an abbreviation for the Latin word Recipe, meaning you take or take thou; so it instructs the pharmacist to take of the ingredients mentioned below the amounts specified. The oblique dash across the final stroke of the R probably is derived from the old symbol % which represented a prayer to Jupiter (the god of healing). It was the custom of the old Roman physicians to begin a prescription with this invocation (the action of invoking someone) their God of Gods to bless the remedies.
Another theory exists that the “℞” may have originally been a “Px”, where the “P” is short for “pre”, and the “x” is short for “script”.
It is the main body of the prescription. The inscription is that part which contains the name of the drug or drugs ordered and the amount desired. It is usually best written in Latin.
