And apply medical trial standards. And everyone benefits, evem treatment isn't successful there are research results to work with.

I strongly agree. The makers of the treatment recoup their investment once the treatment goes into prod. But while in beta, it should be free to the patient. Without this rule, I can imagine a world where businesses make a living selling treatments that are never intended to get past the FDA's certificatuon process.

Not charging would prevent treatments like the one in this article which would presumably be expensive. I think better that a doctor has to sign off a bit of paper saying they feel the treatment is reasonable. They'd be reluctant to do that for snake oil.
