[Question] asking for the validity of a recipe

Hey all, i was reading the book World War Z and in it a character gives this ingredients list for root beer;

Ingredients: molasses from the United States anise from Spain licorice from France vanilla (bourbon) from Madagascar cinnamon from Sri Lanka cloves from Indonesia wintergreen from China pimento berry oil from Jamaica balsam oil from Peru

Is this an actual list of ingredienfs for root beer or is it bs?

Thanks, F,
