New research shows that pynogenol, an extract from pine bark, significantly decreases pain and inflammation related to arthritis.  The study followed 156 patients with painful arthritis of the knee; 77 were given 100mg of pycnogenol per day, while the remaining 79 were given a placebo.  After 3 months the treatment group outperformed the placebo group with less pain, increased walking distance, less edema (swelling) in the foot, and 58% less anti-inflammatory use.  

A follow-up to that study found large reductions in CRP (an inflammatory marker in the blood), fibrinigen (an indicator of inflammation and fibrosis), and free radicals following pycnogenol use (read the study here).

Keeping in mind that the diseases that plague modern man are all associated with inflammation and free radical production, on would expect pycnogenol to be helpful in other disorders as well.  A review of the literature over just the recent pasts reveals the following (you can click each topic to read the research): pycnogenol is very effective in the treatment of diabetes, fertility disorders, ADD/ADHD, and dementia (pycnogenol improves memory).
