Let’s take a little excursion into languages, and see what some others think.
the book Devils, Drugs, and Doctors: The Story of the Science of Healing from
Medicine-Man to Doctor (1929) [available in paperback (2003)] by Haggard had it
partially correct at least when it said: "Rx is not, as is frequently supposed,
an abbreviation of a Latin word meaning recipe or compound, but is an invocation
to Jupiter, a prayer for his aid to make the treatment effective . . . sometimes
in old medical manuscripts all the R's occurring in the text were crossed."
The Facts on File Encyclopedia of Word and Phrase Origins came to the
rescue, however, with what is certainly the correct answer:
“The Latin ‘recipe,’ take,’ provides the R in the symbol Rx used by
pharmacists for centuries, while the slant across the R’s leg is the sign of the
Roman god Jupiter, patron of medicine.”

It is evident that the RX symbol, which was anciently
associated the Egyptian Horus, Osirus, as well as with Jupiter, was in turn
applied to the ‘saving’ attributes of the bearer.

Origin of ‘Rx’ Symbol May Lie in the Eye of an Egyptian
The "Rx" symbol is recognized by pharmacists and laypersons worldwide, but
its origins may be older and more exotic than many might think. According to a
recent article by clinical pharmacologist Jeff Aronson in the British Medical
Journal, the symbol does not represent the letters "R" and "x," an abbreviation
of the Latin word for "recipe." Instead, he contends, the symbol derives from
the symbol used by ancient Egyptians to signify the utchat, the eye of the
ancient god Horus the Elder.
Egyptian legend holds that Horus
had two eyes, the sun and the moon. Set, the god of darkness and evil, stole the
sun eye. The deity Thoth attempted to end the conflict, but Set kept battling
and cut off pieces of Horus’ remaining moon eye, which Thoth renewed each
month—tidily explaining the lunar phases. Because of the theme of miraculous
restoration, "the eye of Horus became a potent symbol of good fortune and
healing, later adopted by the Greeks, Arabs, and others," according to Aronson (BMJ
1999;318:1543).
The eye symbol is easily recognized
as the letter "R." In recent times, the use of "R," followed by "x" to indicate
an abbreviation, has led to many new abbreviations, such as "Hx" for history and
"Dx" for diagnosis.
Four amateur historians have
already written to the journal to refute Aronson’s hypothesis and offer
alternative theories about the origins of the "Rx" symbol.

“The sacred monogram Chi-Rho, so called because composed of the Greek letters
chi (C ) and rho (R), is of Egyptian origin. According to Sir Flinders Petrie,
the Egyptologist, the monogram Chi-Rho was the emblem of the Egyptian god,
Horus, thousands of years before Christs.” [
