15. Researchers at the University of Palermo reported in the American Journal of Clinical Nutrition that consuming prickly pear had a more positive and complete effect on the body's redox balance than a comparable dose of vitamin C. 


16. Studies at Tulane University reported in the Archives of Internal Medicine, that taking prickly pear fruit extract before drinking alcohol significantly reduced symptoms of a hangover (nausea, dry mouth, and loss of appetite.)


17. A study at the University of Arizona, funded in part by the American Heart Association, found that LDL (bad) cholesterol levels were reduced in guinea pigs fed a diet including prickly pear pectin. A meta-analysis of studies done on prickly pear and diabetes has strongly suggested that ingestion of the fruit has a true metabolic effect on persons with the disorder and reduces serum glucose levels.


18. Italian research has also shown prickly pear to be protective against ulcers in rats.
