Charles Leiper Grigg came up with the formula for the lemon-lime soft drink and launched the product two weeks before the Wall Street Crash of 1929.
The original name, “Bib-Label Lithiated Lemon-Lime Soda” was later shortened to “7 Up Lithiated Lemon Soda” before being further shortened in 1936 to “7 Up.”
[Lithium citrate is a chemical compound of lithium and citrate that is used as a mood stabilizer in psychiatric treatment of manic states and bipolar disorder.]
The drink contained a mood-stabilizing drug, until 1948. It was one of a number of patent medicines (heavily advertised over-the-counter products) popular in the late-19th and early-20th centuries.
An early version of Coca-Cola, also available in pharmacy soda fountains, called Lithia Coke, was a mixture of Coca-Cola syrup and lithia water. When launched (1880s) Coca-Cola’s two key ingredients were cocaine and caffeine. In 1903 cocaine was removed.
