According to Bulletin 133, Bureau of Plant Industry, United States Department of Agriculture, valuable fixed and volatile oils can be produced from the kernel of the peach. Peach-stones are now burned as fuel by most canneries, excepting small quantities sold to nurseries for propagation. The possibility of producing oils from the kernels seems well worth looking into, since there is now an enormous waste of this part of the fruit by canneries. Oils extracted from peach-kernels may be used for the same commercial purposes as the almond oils; namely, in medicine, for soaps, cosmetics, perfumes and confections. The processes of extraction and distillation are not complex and establishments equipped with steam would have little difficulty in extracting these oils. It is said, too, that the press-cake from which the oils have been extracted makes valuable stock-foods or fertilizers owing to its high content of nitrogenous matter. It is estimated that in California alone the quantity of peach-pits obtained as a by-products of canneries amounts to 10,000 tons in a normal year; that these would yield from 600 to 1,200 tons of kernels from which 210 to 420 tons of oil could be extracted. The wholesale price of bitter-almond oil, or oils purchased under this name, for which peach-oil could be substituted, is from $3.25 to $4.75 per pound. Pliny named several medicinal uses for the peach and from his time down the flesh, kernels, leaves, bark and blossoms have had a place in the pharmacopoeia of various countries though nowadays little used except in domestic therapeutics. All of the structures named abound in a bitter and astringent principle and most of them produce hydrocyanic acid upon maceration with water. The peach might have value in medicine for this acid were not the chemical more easily obtained elsewhere. The oils from the kernels, as we have seen, may be used in medicine. Noting the medicinal uses to which peach-products have been put by various peoples in various times we find: The leaves are pounded and boiled in vinegar for a liniment, an eye-wash, a cure for "scurf," a preventive of bald heads, and as an insecticide on the heads of children. The blossoms, treated in various ways, have been used for the same ailments and also as a febrifuge. The burned pits are also used in making lampblack for paints.
