Young girls suffering from disturbances of their general health dependent upon a scrofulous or rachitic habit of body may with advantage be sent to brine baths, especially to such as are situated in the Alps or other mountainous regions. These weakly, lymphatic, scrofulous girls, suffering from scanty or irregular menstruation, may also practice sea-bathing with advantage, especially at watering places on the sea coast, where the waves are powerful. In such cases, however, it is advisable in the first instance to take artificially warmed sea-water baths, before proceeding to actual sea-bathing. If the sensibility of a chlorotic patient is so great that she can endure neither peat baths nor carbonic acid containing mineral water baths, we must add to the latter, in order to make their action milder, decoctions of chamomile, wheat bran, malt, and the like. In cases in which nervous symptoms predominate, with an apathetic, melancholic frame of mind, aromatic herb baths are sometimes useful. For this purpose such herbs should be employed as contain a notable quantity of ethereal oils, such as sage (salvia officinalis), wild thyme (thymus serpyllum), hyssop (hyssopus officinalis), wild marjoram (origanum vulgare), rue (ruta graveolens), archangel (archangelica officinalis), levisticum (levisticum officinale). Equally useful are the balsamic pine needle baths, for which the fluid obtained by the distillation of pine needles (pinus sylvestris), freshly collected day by day, is employed. As regards the climatic conditions suitable for adolescent girls suffering from the disorders of the menarche, from the nervous conditions associated therewith, and from chlorosis, residence either in the mountains or at the seaside is especially to be recommended. An altitude of about 1,200 metres (4,000 feet) is the most suitable, being that at which the peculiar characteristics of mountain climates are most fully developed. The influence of such a climate on hæmatopoiesis has to be taken into consideration, as well as its special influence on the menstrual function.
