I personally use turkish falim gum, you can get it basically without flavor, it's pretty hard and you can chew on it for >1h without it tasting weird

glycyrrhizic acid in licorice can drop your blood potassium level and cause cardiac arrhythmia, however, as well as commonly raising blood pressure [1]
