Oblong bottle for quinine salicylate pills

Oblong bottle for quinine salicylate pills, brand name "Quinisan", with contents, by Howards and Sons, from Savory and Moore's shop, English, 1900 to 1940

Developed in the late 1920s and early 1930s Quinisan was a preparation of quinine bisalicylosalicylate, developed by Howards and Sons. Their adverts claimed “in 3 cases out of 4 they will definitely stop a cold. Quinisan is not a quack medicine; it is a highly scientific new salt of quinine.” The maker’s also marketed it for flu and tonsilitis. Quinine was used for cold and flu remedies, following its belief in reducing fevers for malaria. However, it was later realised and accepted that quinine’s success at fighting malaria was due to its direct action on the parasite causing the illness.
