Could you elaborate? If you are referring to vest kavauh, the nishtaneh
was (at least in major part) the invention of indoor electric lighting.
A woman can induce more regular periods if she goes to sleep at sundown
with the light in the room reflecting the moons light; i.e. a full moon
= a small night light, no moon = darkness.

This would jibe with women in Yerusalem 50 years ago, as well as poor
women in Africa.
