In medieval times I was used in a compound as a headache remedy and through out history I have been used in compounds to make salt, soap, textiles and pickle foods. It was not until 1807 that I was finally isolated as a single element by Humphry Davy. To isolate me by myself Davy sent an electric current through molten sodium hydroxide. As a compound I have many uses but as a single element I am very limited.
