I do believe that one's brain is capable of changing one's body chemistry. It happens all the time on a daily basis. However.........."pointing the bone" does not mean the person who points has any power to change the subject's body chemistry. It is the symbolism in the act of pointing the bone, usually for good reason, that affects the thinking of the subject, which then in turn changes the subject's body chemistry in a detrimental way.. A form of hypnosis (mental suggestion). However, I doubt that this would work, unless the subject actually witnessed the *imposed punishment* personally, and I can't accept that sticking a pin into a rag doll to inflict pain on someone far removed (unaware) would be negatively affected. But I did just run across this and somehow, I feel this may be tangently connected to the practice of voodoo and *curses* as an example of the subject's mirror neural system being able to *believe* the curse and thereby begins a process of biochemical self-destruction.

And factors in old blood interfere with the process in the brain of a young mouse (second from left). https://www.sciencenews.org/article/old-blood-carries-risks-brain As the brain is a computer, running the body, I can visualizing implanting a slow acting mental *program virus* in the subjects brain and the subject begins to mentally self destruct. The above, shows that the chemistry of blood changes with age, which means it can change as well in younger subjects. Perhaps a little farfetched, but perhaps worthy of consideration.
