I'm actually not that of "Bio-type", but environmental and nature-conscious behavior is important for us from day to day. And with "Neem" I have no hesitation to wash the herbs after a few days and eat later. In many forums Neem has been highly praised and I can only agree with the No "side effects", but very very good effect! I am more than surprised and would recommend it only! And someone should again say "organic would have no effect" ...
