I had come upon this link (http://www.breville.com.au/75thbirthday/sharedStories.asp?page=40) last year when I was doing some research on Hodgkins Lymphoma. Apparenty, they came across "a vegetable juice which contained all sorts of things such as celery, carrot, parsley, ginger & beetroot. This recipe was found in Lance Armstrongs book "It's not about the Bike" ." Apparently the person using this juice recipe "has been in remission for 6 years now."
Though not a tree fruit based juice, it seems to lend credibility to recovery through diet and nutrition.
