It seems like there might be some confusion in your question. If you're asking about the term "physician" and its origins, I can help with that!
The word "physician" comes from the Middle English term "physik", which in turn derives from the Old French "fisicien" and ultimately from Latin "physica", meaning "natural science" and related to "physicis" meaning "nature." The term has been historically used to refer to a person qualified to practice medicine, particularly one who diagnoses and treats illness.
