going down?

As with cocaine in Coca-Cola, lithium was widely marketed as one of a number of patent medicine products popular in the late-19th and early-20th centuries, and was later to evolve into a refreshment beverage.

7 Up was created by Charles Leiper Grigg who launched his St. Louis-based company The Howdy Corporation in 1920. Grigg came up with the formula for a lemon-lime soft drink in 1929. The product, originally named "Bib-Label Lithiated Lemon-Lime Soda", was launched two weeks before the Wall Street Crash of 1929, just when it would be most needed. It contained lithium citrate, a mood-stabilizing drug. It was one of a number of patent medicine products popular in the late-19th and early-20th centuries; they made claims similar to today's health foods. Specifically it was marketed as a hangover cure.

The product's name was soon changed to 7 Up. According to Professor Gary Yu (UCSB) and researchers for the once popular "Uncle John's Bathroom Reader" the name is derived from the atomic mass of Lithium, 7, which was originally one of the key ingredients of the drink (as lithium citrate). Lithium citrate was removed from 7 Up's formula in 1950.
