The produce for juicing on the therapy is what really cost the most, doing 10 juices a day it was about $250 weekly and then for eating food maybe another $100, remember everything you eat and use must be organic and fresh.
I wash/soak the head of reb cabbage on my veggies wash day however no I don't wash the individual leaves. I've been doing this over a year and never had a problem so for me it works.
