I agree with the author that Dr. Carson is the last person you would expect to find in a shady sales video like that. Alternative / natural medicine has its place — but as a cancer cure pretty dubious. This lowers my opinion of him. He of all people should have known better. You can’t argue with his proficiency as a neurosurgeon but judgment?
Where did the article say he claimed it was a cancer cure? Symptom reduction is not a cancer cure. This article says he said it reduced his symptoms. Who wouldn't want to try something herbal if it works as well as the more invasive, more expensive big pharma meds?
