Well, with real life substances, that concoction seemed plausible, as bile is alkaline, seed oil varies a little from mildly alkaline to acidic, while fruit juice is acidic, but shortly after re-reading the prior messages, I did kinda realize that if the seed oil + bile + the bitter aboline turned out neutral, this mix would be more acidic, as it ditched the bitter aboline and threw in another acidic component. But oh well, it still fit, Taizee shouldn't have any knowledge of this stuff, and her reasoning still makes sense!
