謝謝分享！Cancer Research UK 的網站上有介紹，尤其對其安全性有所提示，可以參考一下。

The safety of Gerson therapy Some elements of the Gerson diet are healthy, like eating low fat food and lots of fresh fruit and vegetables. But taking this to the extreme and eating very large quantities of one food group in a certain way (juicing), without balancing it with other food groups, isn’t healthy. In fact it can be very harmful for people who are already weak and ill. There are also many harmful possible side effects. Most Gerson therapists encourage people not to use chemotherapy while having Gerson therapy because they believe that chemotherapy damages immunity. Radiotherapy is thought by Gerson therapists to be more compatible with their treatment. It is up to you to decide whether you want to use any alternative therapy. But we do not recommend that you use them instead of your conventional treatments. Stopping your conventional cancer treatments and methods of symptom control methods can be very harmful. You need to talk to your own specialist about any alternative or complementary therapies that you want to try. It is important to find out all you can about the therapy before deciding to use it.
