I think I'd be a little disappointed to find out my T believed in homeopathy and things like that. But I do happen to know he believes in spiritual things and has some religion which I don't at all. But he never mentions it in sessions and it's never gotten in the way of my therapy. I would say as long as she's keeping her opinions on that to herself in the therapy room, it probably won't affect your work too much.
That said, do talk to her about it if it is troubling you.
