The rose hip, or rose haw, is the fruit of the rose plant, that typically is red-to-orange, but ranges from dark purple to black in some species.
Rose hips contain plenty of lycopene, an important and strong antioxidant that is an integral part of low density lipoprotein (LDL) as well as of many cellular membranes. Lycopene in rosehips differs more in its isomer distribution than in other sources (tomatoes, pink grapefruit). Rose hips also contain some vitamin A and B, essential fatty acids and antioxidant flavonoids. A study of a rose-hip preparation for treating rheumatoid arthritis concluded that there was a benefit, apparently due to both anti-inflammatory and anti-oxidant effects. [Source: Wikipedia]
