This question came to my mind and was curious as to the answer. Medical boards in both human and veterinary medicine require a standard of care. That implies using a certain protocol for each disease. Like my vet as an example follows the standard of care for polycythemia and investigates accordingly suggesting x ray, ultrasound etc... and if that diagnosis is made there are certain standards like phlebotomy or the chemo drug to treat. If they don't do that, aren't they out of compliance. But in alternative and the above medical practices, the standard of care is not followed (or it would not be alternative medicine). I guess I am asking, if my own vet wanted to use something not in the standard of care to treat polycythemia is that ok with the med boards. Like I think one of my vets over the years mentioned CBD oil for a dog but would not sell or recommend that formally but holistic vets do that all the time, What is the difference as to how they can practice that way but a strict allopathic vet might get into hot water.
