The wisest of conservative physicians understand and embrace how little effect the clinician has on outcomes.
Blah blah blah.
Now if only more doctors/medical researchers were intensely curious about how to better support the body's "inherent healing properties" effectively. Then we might see a real sea change that is both dramatic and actually, in fact, honors the pledge: First, do no harm.
Edit: Would people be happier if I said "This is nonsense." instead of "Blah blah blah"? (Serious question here. It says the same thing to me and someone else has made much the same point and been upvoted for it.)
