Apples are a wholesome vegetable aliment and in many cases medicinal, particularly in diseases of the breast and complaints arising from phlegm. But, in general, they agree best with the stomach when eaten either roasted or boiled. The more aromatic kinds of apples are the fittest for eating raw. Pears resemble much in their effects the sweet kinds of apples, but have more of a laxative quality, and a greater tendency to flatulence. Cherries are in general a wholesome fruit, when they agree with the stomach, and they are beneficial in many diseases, especially those of the putrid kind. Plums are nourishing and have besides an attenuating as well as a laxative quality, but are apt to produce flatulence. If eaten fresh, and before they are ripe, especially in large quantities, they occasion colics, and other complaints of the bowels. Peaches are not of a very nourishing quality, but they abound in juice, and are serviceable in bilious complaints. Apricots are more pulpy than peaches, but are apt to ferment, and produce acidities in weak stomachs. Where they do not disagree they are cooling, and tend likewise to correct a disposition to putrescency. Gooseberries and currants, when ripe, are similar in their qualities to cherries, and when used in a green state, they are agreeably cooling.
Strawberries are an agreeable, cooling aliment, and are accounted good in cases of gravel. Cucumbers are cooling and agreeable to the palate in hot weather; but to prevent them from proving hurtful to the stomach, the juice ought to be squeezed out after they are sliced, and vinegar, pepper, and salt afterward added.
