I know that when adding carbonated water with Yerba Mate leaves there is a reaction that removes the carbonation. (Empirical results)

I wonder what actually causes such reaction but looking in Scholar even for similar reaction such as soda + mate wasn't very productive.

What is the reaction that undergoes there? Is mate just a catalyst ?

    $\begingroup$ The carbonate is supersaturated in solution and unstable. That is why if you just leave a bottle of carbonated water open it will go flat. I'm guessing that the Yerba Mate plant goo has particulates in it which act as nucleating sites for bubbles to form. With a lot of bubbles forming you'll lose the fizz quickly. $\endgroup$ – MaxW May 16 '16 at 16:08
