Abstract: A formulation having a rose hip concentrate is used to treat and/or alleviate the symptoms associated with inflammation including arthritis or to prevent development of arthritis. The rose hip concentrate has a high vitamin content relative to conventionally dried material, and is shown, in vitro, to inhibit the chemotaxis and oxidative burst response of human peripheral blood inflammatory cells, as well as the chemotaxis of monocytes. The formulation, in vivo, was found to inhibit chemotaxis of human peripheral blood inflammatory cells and to reduce the level of C-reactive protein, to alleviate pain and reduce inflammation in patients with arthritis.
