Why is RX used for prescription?

Never have figured it out. please explain. Also why is lbs used for pounds? Thanks
Answer:
It isn't really Rx at all. It's R with a line through the leg of the R. It's an abbreviation for the Latin "recipe," meaning "take thou," a simple direction.
A typical prescription would be written in this form:
Rx Miraclecillin 500 mg
#15
Sig: i bidThe first line directs that you take Miraclecillin in the strength of 500 milligrams.
The second line tells the pharmacist to dispense 15 pills.
The third line directs the pharmacist to label the prescription "one bis in diem" which he will conveniently translate to "one twice a day."
I have noticed that as fewer and fewer people study Latin, grammatical errors have become common in medical Latin; for instance, the correct form for "daily" should be "O.D." for omni diem, but "Q.D." seems to have thoughtlessly found its way into common usage. The romantic side of me bemoans this state of affairs, but the point will soon be moot. Computers will simply print the word "daily" in plain English.
I had always heard it stood for recipe mixture
Rx - its a sign of respect to god tht pls help us in wat we r doin
Rx. symbol, [Latin. rec'ipe] (take)
lb. [Latin. li'bra] (pound).
I think it is an abreviation of a latin word
Its interesting that QD is not the correct term for "every day" but rather OD, which is the abbr. for right eye.Less confusion maybe?
Rx,is an abbreviation of word recipe.In Latin,it means let it be made.In modern language,it means the order of drugs and their respective information to be given to a patient,written by a physician to a pharmacist. It is thought that it also symbolises,Greek god of heeling,i.e. Jupiter.So writing it at the begining of a presciption indicates that,the patient be blessed by God for the effects of the drugs he is taking.
