What does the 'Rx' stand for.?

Question

We generally find this 'Rx' on doctor's prescription,round the world.

Answer 1

Actually, that was something I've always wondered myself, so I did a little research and found this:

"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.

Another explanation for the origin of Rx is that it was derived from the astrological sign for Jupiter which was once placed on prescriptions to invoke that god's blessing on the drug to help the patient recover."

Answer 2

I know that Rx in chemistry means reaction. So instead of writing out reaction all the time, they just write Rx.
