This is a disease characterized by chronic anaemia, or bloodlessness, affecting females about the age of puberty. In some instances it is undoubtedly dependent upon a nervous affection, but in most instances it is connected with disordered menstruation and other causes. The red corpuscles of the blood are pale and small, and diminished in numbers. The countenance assumes a wax-like hue, which is so remarkably characteristic, that the disease is called by nurses "green sickness."  The appetite is irregular, with craving for particular kinds of food, the urine is thick and full of sediment, and there is usually vertigo, headache, backache, hysterical affections, dysmenorrhoea, and leucorrhoea. The tongue is flaccid and indented at the edges, the pulse is weak and quick, and there is a feeling of general languor, with great indisposition to bodily or mental exercise.

TREATMENT. -- When arising from feeble and imperfect digestion, give prickly ash, alder, golden-seal, and nux vomica, cautiously. The animal oils are also very serviceable. The great object in the treatment of this disease is to restore the general health, and not to force menstruation by agents having that power. The patient wants strength and blood, and when that is achieved, menstruation will be natural. Baths, friction, out-door exercise, and a nutritious diet should not be neglected.
