Rose hips are the fruits of a wild species of rose bush commonly known as dog rose. The hips, or haws, which mature in late fall, are one of the best sources of vitamin C known. During World War II, British soldiers were supplied with rose hip syrup to compensate for the lack of fresh citrus fruit.

Rose hips are also rich in antioxidant flavonoids and pigments, such as lycopene. They also provide iron and vitamins A, C, D and E.
