7-Up was created by C.L. Grigg in 1929, just weeks before the Great Depression began. Originally titled 'Bib-Label Lithiated Lemon-Lime Soda,' it contained lithium citrate, a mood-stabilizing drug used to treat various mental health conditions. The '7' in the name is rumored to refer to the drink's original seven ingredients, while 'Up' may have referred to the 'uplifting' effects of the lithium. It was marketed as a cure for hangovers and a way to improve mood. The US government banned the use of lithium in soft drinks in 1948, and the formula was changed. Despite the removal of its 'medicinal' ingredient, 7-Up remained one of the most popular lemon-lime sodas in the world, known for its crisp, clean taste and 'Uncola' marketing campaigns.
