i've never heard anything about that. all i can add is that i too have very irregular periods and i can't claim any long lasting related to my cycle. as recently discussed here, it seems the Master-Cleanse often bring on a period. it did for me with each MC.

What are anthroposophic remedies? Herbalists say that you won't have much of a period if you are toxin free. WHy are you trying to induce it?

I've never bothered to notice when my period was happening before starting. It doesn't seem to make a difference. When you are on the cleanse, you may have yours delayed further or started early. Mine seem to be delayed 2-4 days when I'm on the cleanse. But nothing terrible.
