Mary Jane helps in counteracting all of chemotherapy\'s side affect like nausea, pain and lack of hunger. In fact, all of Mary Jane\'s side affect completely overwhelms the side affect of chemo.
They get hungry (which sustains health)
It counter acts nausea (a good thing since your body needs all the nutrients it can get)
Dulls the pain of chemo (chemo was described to me as someone taking a screw driver and prying your joints apart with it).
