The nervous system naturally suffers when it does not receive a due supply of healthy blood: depression and a sense of oppression will be felt, and hysterical and hypochondriacal symptoms will be more or less pronounced: in such cases, iron is often a valuable adjunct to other treatment, and is especially suitable when combined with bromides. In the nerve-symptoms which commonly occur in women at the climacteric period, including restlessness, anxiety, fluttering and sinking at the epigastrium, giddiness, clavus, and sometimes menorrhagia, the perchloride, with or without bromide, relieves much.
