How about a series where people get treated for the same things by different cultures doctors?
For instance Joe comes in with back pain and is treated by a European trained doctor, a Chinese medical practitioner, etc....You could even go all out. There are over a hundred forms of alternative medicine listed in Wikipedia, all the way from Accupressure to Zang fu theory.
At the end of the diagnoses each patient could decide on the type of treatment they want and tell their reasons for it. And as the series continues the patients could give updates on how the treatments worked for them.
Couldn't be used for serious conditions but would be interesting, informing and possibly great fun!
