Lithium is an element. It gets its name from âlithos,â the Greek word for stone, because it is present in trace amounts in virtually all rocks. Lithium works with other elements, drugs, enzymes, hormones, vitamins, and growth factors in the body in many different ways. People use it for medicine. Lithium is used for mental illnesses, including bipolar disorder, depression, and schizophrenia; for eating disorders, including anorexia and bulimia; and for blood disorders, including anemia and low white-cell count (neutropenia).
