Trivia

Eno's Fruit Salt is referenced in The Birthday Party by Harold Pinter in the famous interrogation scene between Stanley, Webber, and McCann.

In The Riddle of the Sands (1903), a novel by Erskine Childers, Davies says: "After that I taught myself to make rolls; had no baking powder at first, so used Eno's fruit salt, but they wouldn't rise much with that".
