Nature is not so defective in her own judgment as to require auxiliaries. Care should be taken to improve the general state of the health, by attention to diet, moderate exercise, change of air, &c. In some instances the menstrual discharge does not make its appearance before the age of seventeen or eighteen, and, nevertheless, health is not in the least affected. The mere want of evacuation at the ordinary time, therefore, is not to be considered as morbid, unless the system be evidently deranged thereby. In many cases, however, symptoms of disease appear which are evidently connected with the defect of the menses, and go off upon its discharge. The treatment, in such cases, must be regulated by the particular circumstances and constitution of the individual. There is no remedy adapted to every case of this kind; but an open state of the bowels, and a due regulation of the diet, together with moderate exercise, are useful in every instance of this complaint. Warm clothing, too, particularly about the lower extremities, is of most essential benefit. The occasional use of the warm bath is pleasant and beneficial, especially if the skin be dry and warm. As the health improves, the cold bath will prove an auxiliary, if, after using it, the patient feels a glow of heat and a greater degree of liveliness. When the means ordinarily employed have failed, marriage, or a change of climate, has produced the wished-for effect. In some instances the evacuation is impeded by a mechanical cause, that is an obstruction of the passage to the womb. This occasionally is met with, and the chief obstacle to its speedy removal is the difficulty of ascertaining its existence. The operation by which it is completely remedied, is not more painful nor formidable than blood-letting. Fortunately, in most cases, the evacuation takes place in due time, and the constitution sustains no material or permanent injury. It is, however, in every instance, proper to pay particular attention to the system during the continuance of the evacuation. The stomach and bowels, at this period, are very easily disordered, and therefore, everything which is heavy or indigestible, ought to be avoided. Some are hurt by eating fruits or vegetables; others by taking fermented liquor. In this respect experience must enable each individual to judge for herself. Exposure to cold, particularly getting the feet wet, is hurtful, as it tends suddenly to obstruct the discharge. The same effect is likewise produced by violent passions of the mind, which are also, at this time, peculiarly apt to excite spasmodic affections, or hysterical fits.
