"there haven't been any clinical trials testing whether raspberry cordial can prevent or treat stomach bugs in humans or animals"
"[But] we cannot say for certain that the cordial will definitely prevent stomach bugs in people, and we don't know yet if it will help as a treatment if you are already feeling sick. Although again there is some anecdotal evidence to suggest that it might."
