She is saying 'No' to everything. All blood, all components, fractions and products. This is simply because, in the face of so much intimidating and confusing rhetoric she has retreated to a position she can understand - just say no.
That's the same position my mother is taking. It's almost as if she prefers to be told what to do rather than have the opportunity to make an informed decision. It makes it awkward for me, as I alone have power of attouney for her personal care - my sisters have been excluded from that.
Edited to add: My mother still believes we shouldn't use fertilizers that contain blood in our gardens. Can't have that blood going into our tomato plants now, can we?
