The fruit (rosehip) of the dog rose plant, used in herbal medicine and culinary preparations.
From Greek 'cyno-' meaning dog and 'rhodon' meaning rose; the suffix '-on' makes it a neuter noun, with the same origin as cynorrhoda but in a slightly different grammatical form.
During World War II, when citrus was scarce, the British government sent children to pick wild rosehips (cynorrhodons) to make vitamin C syrup—a genius use of a 'worthless' wild plant!
