I presume the product could easily contain whole blood, and this is a transfusion process. Has the WTS openly objected to this process, which is a procedure that is medically accepted and administered - that has save many lives and influenced various serious ailments with some patients.
I shall need to research this. My questions include the timing of its modern application, as compared to the timing of the WTS's start of opposing the tranfsusion of blood (relaxed somewhat in recent times), and if it was an ancient medical practice.
If you get the chance, watch "Life On Us, Part 2: Superhuman". (Try YouTube - at a cost.) Part 1 is also amazing, about the animals and stuff that live on our skin.
