Pycnogenol, a pine bark extract from the French maritime pine tree has been shown to reduce overall knee osteoarthritis symptoms by 20.9 percent, and lower pain by 40.3 percent, in a third clinical trial on osteoarthritis treatment with Pycnogenol.
Pycnogenol acts as an anti-inflammatory and the study also suggests that Pycnogenol may assist the joints in recovery.
The 3-month study involved 100 patients with stage I or II osteoarthritis, and were supplemented with either 150 mg Pycnogenol or placebo every day.
Overall knee osteoarthritis symptoms improved showed a significant 20.9 percent improvement in the Pycnogenol group, with joint improvement persisting for 4 weeks after intake of Pycnogenol was discontinued. After the 3-month trial was completed there was a 40.3 percent reduction in joint pain, 2 weeks later the pain was still 36.1 percent lower.
The patients supplementing with Pycnogenol also required significantly less analgesic medication compared to the placebo group.
