Extracts from French maritime pine bark may reduce the pain associated with arthritis of the knee by about 40 percent. It can also result in about a 52 percent improvement in physical function.
Researchers used the Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index as a measure of arthritis symptoms. Pain and physical function scores improved after 60 and 90 days of supplementation with pine bark extract, and after 90 days of supplementation the WOMAC scores for self-reported pain, stiffness, and physical function were reduced by 43, 35, and 52 percent, respectively.
The beneficial effects of pine bark extract might be due to its antioxidant and anti-inflammatory properties.
