5 /5 Natalia Spinelli: Nothing really here but the history I love! Lithium fountain of youth. The healing power of lithium! Today lithium is first line of treatment for bipolar disorder. Little did the People know they were drinking âhappy waterâ but it was promoted as âhealingâ and people poured in. Lithium used to be all over the place until salt substitute containing lithium ruined it for everyone!
