In 1994 a clinical trial at Second Military Medical University in Shanghai that provided subjects with goji juice and the anti-cancer drug LAK/IL-2 showed better treatment results than when the drug was used alone. Seventy-nine subjects showed amazing Goji Sbelt and unexpected regression of cancer. Further research in Asia demonstrated similar regression in patients with malignant melanoma, renal cancer, colon cancer, and lung cancer. Researchers did the math and found that among patients using the drug augmented by the juice from goji fruit, had a positive response rate of 40.9% as opposed to 16.1% of patients who received only the drug. http://gojivitafacts.com/goji-sbelt/
