About Menstruation

[Sheryl]

I read this article:
http://www.allabouttantra.info/en/englis...nstruation

And my question is: what makes menstruation stop? Whatever the belief about why menstruation happens, without a change in lifestyle or still living a life that lacks harmony, if not a natural occurrence then what makes it stop? Or if it evolved from the body needing to rid itself of toxins, what makes it cease when the body continues to be toxic?
