Fenugreek provides a hormone that normally is used to increase milk production during lactation.
Alfalfa, Black Cohosh Root, Cramp Bark, Dong Quai, False Unicorn Root, Fo-Ti Root, Licorice Root, Maca Root, Red Clover, Wild Yam Root would be better choices for Estrogen.
Pueraria Mirifica is also said to help with breast growth, but I haven't found any good studies on it's effectiveness.
