Yes, I read the wiki article so I know that. My point being that first, contrary to what MS's translator said, it has absolutely nothing to do with potatoes. And second, regardless of the real world dosages and other possible usages, Mashima didn't simply do the lazy thing and say that the generic tea was drugged, he actually looked up a tea that has the possibility of making people sleepy. Which is a nice small touch.
