For concern about the aspects of using peach seeds, here is a bit of info about the usage of peach products, Peach Uses & Scientific Evidence For
Peach leaves and bark have demulcent, sedative, diuretic and expectorant properties, and work well to relieve bladder inflammation and urinary tract problems. The leaves and bark can also be used to treat whooping cough, ordinary coughs, and chronic bronchitis. Peach seed (kernel) can be used as a mild laxative, and an expectorant for the lungs, nose and throat, and it can help relieve chest pain and spasms. Peach bark is still used to improve blood flow and eliminate blood stagnation caused by amenorrhea, dysmenorrhea, postpartum abdominal pain, and pain and swelling due to external injuries.
Since there is only one pit per peach and alot of peel, the recipe should not be altered if the peach seed is left out.
