Answer:
Advantages of modern medicine is the scientific approach. We know more about how the human body works & about diseases. Incredible advances have been made including the ability to repair the human body after (for example) car accidents. However, it's disadvantage is sometimes also the science. The double blind placebo controlled trial doesn't work for all investigations - take increasing muscle mass through exercise or the parachute for example. Though we have learned a lot about how & why herbs work.
Much of modern medicine works (in my opinion) to ameliorate symptoms rather than get to the root cause & deal with that. Now, if modern medicine & wholistic medicine practitioners would work together more amicably... that would be advantageous.
