Rosehips, the reddish-orange fruit of rose bushes, provide an excellent source vitamin C, antioxidants and polyphenols, especially when obtained from the dogrose species of roses. Dogroses (Rosa caninea) are the most widespread, natural growing species of roses as indicated by an article published in a 2009 edition of "Chronica Horticulturae." Rosehips are additionally touted to provide relief from a host of medical conditions ranging from cardiovascular disease to osteoarthritis and are clinically studied for their health benefits.
Osteoarthritis Benefits
Rosehips possess anti-inflammatory properties which may prove useful in patients with osteoarthritis. A systematic review published in a 2006 edition of "Phytotherapy Research" found clinical evidence that rosehip powder (obtained from dogrose plants) increased hip and knee joint motility as well as decreased osteoarthritic pain and frequency of use of synthetic pain medications used to treat symptoms. While research is promising, further research may be needed to confirm rosehips as an effective, natural treatment for this condition.
Cardiovascular Benefits
Rosehips also possess carotenoids and vitamin C, antioxidants which may provide cardio-protective effects. An article published in a 2009 edition "Chronica Horticulturae" informs that fruits and berries such as rosehips, possess high antioxidant concentrations and may decrease the risk of coronary heart disease. Rosehips also contain up to 5% pectin (a type of soluble fiber) known to guard against cardiovascular disease as noted by Winston Craig, MPH, PhD, RD for Vegetarianism & Vegetarian Nutrition. Dr. Craig also notes that some clinical studies have discovered rosehips' ability to decrease levels of C-reactive protein. Decreased levels of this protein are associated with a decreased risk of cardiovascular disease.
Other Benefits
Besides osteoarthritis and cardiovascular benefits, rosehips may also provide skin health benefits and contain vitamin E, as well as omega-3 and 6 essential oils. An article published in a 2010 edition of "Horticultural Review" notes that salves made from rosehip oil (which is made from the seeds of rosehips) is used to treat skin problems such as eczema, scars and burns. This article also notes that rosehips contain ellagic acid, a tannin which has been shown to induce cell death (apoptosis) in cancerous cells. Rosehips contain many other polyphenols besides ellagic acid, such as anthocyanins, which give the reddish color to the hip and may provide additional health benefits.
