Another active principle soon extracted from plants was salicylic acid. Salicin, extracted from the willow tree, has been launched in 1876 by a Scottish physician, Thomas John McLogan It was in extensive competition with Cinchona bark and quinine and never became a very popular treatment for fever or rheumatic symptoms. The Italian chemist Raffaele Piria, after having isolated salicylalde-hyde (1839) in Spireae species, prepared salicylic acid from salicin in Dumas laboratory in the Sorbonne, Paris. This acid was easier to use and was an ideal step before future syntheses. Its structure was closely related to benzoic acid, an effective preservative useful as an intestinal antiseptic for instance in typhoid fever. Acetylsalicylic acid has been first synthesized by Charles Frederic Gerhardt in 1853 and then, in a purer form, by Johann Kraut (1869). Acetylsalicylic acid synthesis with carbolic acid and carbon dioxide was improved by Hermann Kolbe in1874, but in fact nobody noticed its pharmacological interest.
