Excellent book, I have marginal zone b-cell cancer and hep c from vietnam, I am currently working with my traditional medical Dr's. but also using as much natural medicine as I can find.I 1st had to get my blood levels healthy enough to be able to be treated with traditional medicine, I believe this was done thanks to the info in this book helping me to process wheatgrass to juice and helping me to grow my own wheatgrass as it is not readily available in the town I live in.
