Persica molli carne vulgaris viridis & alba C. B. Amygdalus Perfica Linn. Peach: a tree common in gardens; with oblong, narrow, pointed, serrated leaves; pale reddish flowers, composed of five broad petala with numerous stamina in the middle, set in five-leaved reddish cups, adhering to the branches without pedicles; and a fleshy fruit covered with downy matter and including a furrowed stone.
The flowers of the peach tree have an agreeable but weak smell, and a bitterish taste: Boulduc observes, that when disltilled without addition, by the heat of a water-bath, they yield one sixth their weight or more of a whitish liquor, which communicates, to a considerable quantity of other liquids, a flavour like that of the kernels of fruits. These flowers appear to be gently laxative: it is said, that an infusion in water of half an ounce of the fresh gathered flowers, or of a dram of them when dried, sweetened with sugar, proves, for children, an useful purgative and anthelmintic; and that the leaves, more unpalatable than the flowers, are somewhat more efficacious. The fruit is of the same quality with the other dulco-acid summer fruits: see Fructus horaei.
