Why are prescriptions also call rx?
There's a debate, but...
There are various theories around the origin of this symbol - some record its similarity to the Eye of Horus, others to the ancient symbol for Jupiter, both gods whose protection may hold been sought within medical contexts. Alternatively, it may be intended as an abbreviation of the Latin "recipe".
RX: A prescription for drug or a medical appliance.
A remedy, cure, or solution for a disorder or problem.
