I don't think THEY know more in Europe than in the US. All information on flushing I obtain from Interenet, from curezone in particular. I decided not to visit any doctors and give a birth to my child naturally. No ultrasounds, no recommendations, no mediactions, nothing... I don't think I need all this things since I am healthy and feeling good.
From what I know about flushing, it is safe to do it while nursing. All the toxins that body dumps get flushed out of your body immediately with the help of Epsom Salts . They block absorbtion of toxins by your intestines and cause diarrea.
