Rx: A medical prescription. The symbol Rx is usually said to stand for the Latin word recipe meaning to take.. It is customarily part of the superscription (heading) of a prescription.
The R part of the symbol stands for the Latin 'recipere' which means 'take this' and it is related to the word recipe. The X part of the symbol is derived from the symbol for the Roman God, Jupiter. It represents a prayer or invocation to Jupiter that the treatment would result in a cure, with divine help.he traditional RX symbol cannot be represented on a typewriter keyboard. It consists of an R and an X which are merged to resemble an R with an extension of the right leg of the R with a stroke across it (I hope that makes sense).
