Andreas should be able to address how the liver flushing will improve and affect your menstrual cycle. I just wanted to say that I have been practicing Uttara Vasti an ayurvedic practice aimed at correcting the mentstrual cycle and aligning it with the lunar cycle, which is thought to bring about a state of perfect health for a woman. So far I am finding that it does work and that it is quite a profound practice. Bri Maya Tiwari teaches this practice and I believe it is outlined in one of her books. I would be happy to provide some more information if you are interested. I have not found any other books on it or anything on the web.
