The business people have medicine have poisoned the minds to profit from this, but this is not to say that all of their medicine is bad. There are circumstances in which medicine can be helpful and it takes a bit of discernment to make that call.
People have been using 'alternative' medicine long before pharma came onto the scene (e.g. Traditional Chinese Medicine).
