Medicinal Use: 
Pine Bark Extract is an extract from the barks of the pines. The barks peeled from the pines are harvested, ground and extracted.

It is a species of pine, native to a wide area of central and southern China, including Hong Kong and Taiwan, and northern Vietnam.

Pine bark has been proved to be a new resource of OPCs, the OPCs extracted from the pine bark does not show any difference in quality and functions except for mild dissimilarity in appearance. 

By its excellent antioxidant activity, OPCs eliminates damages that free radicals, as well as collagenase and elastinase do to the arteries, thus prevents or reverses atherosclerosis. 

Animal evidence suggested that OPCs can slow or reverse atherosclerosis.

Because of its antioxidant activity, OPCs is thought to prevent the skin from excessive ultraviolet radiation and free radicals. Considerable evidences indicate that OPCs protects and strengthens collagen and elastin of the skin, 

so that wrinkle is prevented and elasticity of the skin is kept.

 OPCs in cream form is a popular treatment for aging skin, on the theory that by repairing elastin and collagen they will return skin to a more youthful appearance.

Some small brief studies have been done to look at pine bark extract’s possible usefulness in treating asthma, menstrual pain, blood clots and leg swelling during long airplane flights, 

retinal disease in diabetics, high cholesterol, and other disorders.

In addition, different types of pine bark and have different formulations.

Pine bark extract is made from the bark of the maritime pine tree .The scientific name is Pinus maritime, which contains naturally occurring chemicals called proanthocyanidins. 

It’s well known that people can use to benefit their health duet to it’s a kind of antioxidant is wonderful for the human body.

It can be used for hypertension.58 patients in a placebo-controlled, double-blind, parallel group study were investigated effects of pine bark extract, Pycnogenol, on patients with hypertension. 

Supplementation of the patients with 100 mg pine bark extract over a period of 12 weeks helped to reduce the dose of the calcium antagonist nifedipine in a statistically significant manner. 

The intake of pine bark extract decreased endothelin-1 concentrations significantly compared to placebo while concentrations of 6-keto prostaglandin F1a in plasma were significantly higher compared to placebo.

 Values for nitric oxide (NO) in plasma increased in both groups, but the differences were not significant. 

Angiotensin II concentrations in plasma were lowered in the placebo group to a larger extent than in the pine bark extract group. 

Heart rate, electrolytes and blood urea nitrogen were not changed during treatment in both groups of patients. 

Unwanted effects observed in both groups were of mild and transient nature,

 such as gastrointestinal problems, vertigo, headache and nausea.
