Ignorance and scepticism are a double edge sword. The problem is absence of curated information. The fact that she believed in how homeopatic medicine worked, or that he believed in aura cleansing, has nothing to do with the capability of the method itself, but with the source of knowledge for the carrier of the method. There are alternative medicine that work wonders, there are concepts of aura. The application of the method is wrong: non physical nature of the aura concept presented via foreign means to the method itself: a device. Or, the context is wrong: general immune system boost with alternative medicine will also cover the fact that her organism could fight off a specific case of infection. While she is ignorant in why that might have worked, I would not equate the method with the application of the method in your post.
