Thank you, PAA.
The HLM he refers to is not mitzvah related, it is sakanah related. He also says he is not being mechadesh it, he sources it in the Gemara. I don’t think you need to say that he exaggerated, I think this point is clear. It’s not in the category of shiurim, chatzizin, and mechitzin; it means we have a mesorah of the proper medical procedure which trumps contemporary science’s views, and he proves this from the sugya.
Even if we accept Sam’s premise that it’s an obvious exaggeration, at least we see where he’s coming from from his opening paragraph. Is there the same kind of “hint” in the other sources? If not, we must assume that at least those sources are literal.
