it is difficult to find exactly what you want. I also have not found anything with resveratrol and oral cancer with respect to ongoing trials.

Perhaps we have to do our very own personal trial with the occasional glass or red wine.....

(note of caution this was JUST a cell line study, and once you ingest the wine you will of course greatly dilute the substance.... but still.
