Of the complaints which befal women in a pregnant state, the most troublesome are a redundance of crudities, continued vomiting, salivation, heartburn, and loathing of food; it will therefore be proper to give directions regarding them. The most suitable remedies are, exercise on foot, food not too sweet, wines which are yellow, fragrant, and about five years old, and moderate drink. All these things are proper for the cure of crudities and vomiting. For medicines, you may give the plant of knot-grass, boiled in water, for drink; and likewise dill, and the Pontic-root, called Rha, in the dialect of its native country. These things may be taken at a meal, or before it. Externally, the flowers of the wild vine, those of the wild or domestic pomegranate, the leaves of the alsanders (_smyrnium_), and the seed of the fennel, may be mixed together according to pleasure, along with dates and old wine, and applied to the præcordium in the form of a cataplasm. Heartburn may be alleviated by drinking warm water, by gentle exercise on foot, and by covering the hypochondrium with soft wool. In the case of those who have an aversion to food, whet their appetite with a variety of articles of a savory nature, and also give dry starch. This last is particularly serviceable to those who long to eat earth, as is the case in the complaint called Pica, which occurs most frequently about the third month after conception; because the fœtus being then weak, cannot consume all the aliment which is brought to the uterus, and hence various superfluities are collected in the stomach; and therefore they have a desire for complicated and improper articles, such as extinguished coals, Cimolian earth, and many more such things. On that account, the affection has got its appellation, either from the variety of colours which the bird Pica possesses, or from its being subject to this complaint. Labour and long journeys will also contribute to restore a desire for wholesome food. But she who has accustomed herself to live in an indolent manner, will not be able, when she proves with child, to bear exercise all at once. To those who loathe food, it may be of service to take acrid substances, and particularly mustard. For swellings of the feet, it may be proper to bind over them the herb anthyllis, soaked in vinegar; or to lay the leaves of a cabbage over them, and to anoint them with Cimolian earth mixed with vinegar, or with alum and vinegar. It is likewise of use to sprinkle the feet with a decoction of the Median apples, called citrons. * * * * * COMMENTARY. We shall commence by giving a short account of ancient opinions on a curious subject not touched upon by our author,—we mean, on the influence of the imagination in pregnant women on the fœtus.
