This cabbage juicing routine was first studied by Dr. Garnett Cheney in 1949 and into the 1950s. In 1949, Cheney published this study, RAPID HEALING OF PEPTIC ULCERS IN PATIENTS RECEIVING FRESH CABBAGE JUICE. In this study, thirteen patients ranging from twenty-six to seventy-two years old with peptic ulcers were given one liter of fresh green cabbage juice daily. Seven of these patients had duodenal ulcers, five patients had gastric ulcers, and one had a gastrojejunal ulcer. All patients showed rapid improvement compared to standard diet and medications. In eleven out of the thirteen patients, the ulcer craters disappeared within six to nine days. For the other two patients it took fourteen and twenty-three days for the ulcer craters to heal. Overall, the average healing time for the total of thirteen cases of peptic ulcer treated with cabbage juice was nine days
