Treating osteoarthritis with pycnogenol
Pycnogenol is a scavenger of oxygen free radicals. Here’s the latest in a series of positive studies.
First, the details.
- 156 people with osteoarthritis were assigned (not randomly) to take 100 mg pycnogenol capsules daily or placebo for 3 months.
- Symptoms were evaluated using WOMAC scores (for pain and stiffness), and mobility.
- Neither the patients nor the researchers knew the treatment given (blinded).
- Both groups were similar for age, gender, WOMAC scores, walking distances, and use of anti-inflammatory drugs.
And, the results.
- Walking distance on the treadmill was significantly longer with pycnogenol — from 68 m at the start to 198 m after 3 months treatment.
- There was no improvement in the placebo group.
- Drugs use with pycnogenol decreased significantly by 58% vs 1% with placebo.
- Gastrointestinal complications decreased by 63% with pycnogenol vs 3% with placebo.
- Overall treatment costs were reduced significantly with pycnogenol vs placebo.
- Foot edema decreased in 79% of pycnogenol patients vs 1% with placebo.
The bottom line?
Aside from the obvious positive results, another thing strikes me about pycnogenol after about 2 years of blogging on CAM.
The supporters of pycnogenol have embarked on an ambitious program of research that has resulted in a series of positive articles. Some are summarized here.
Eight years ago, I wrote jokingly about the politics of pycnogenol. I said, “We await the supporting clinical trial results.”
Now, the support is being published. We look forward to confirmatory studies.
