A simple way to stem most snake oil is to put all payments for snake oil treatments into escrow till the treatment is approved.
Then the snake oil manufacturer can peddle their unapproved treatment to as many people as they like, but they are losing money on every dose unless the treatment turns out to be safe and effective.
Obviously you need a big team of scientists on the approval panel to make sure no snake oil salesmen are faking trial data to get their payday, but that seems solvable.
