Pine trees are an ancient genus of evergreen trees, with over 100 species growing abundantly in the northern and parts of the southern hemisphere. Historically, many cultures have utilized various parts of pine trees, including the bark, needles, resin, and nuts, for medicinal purposes.
In the 1940s, scientist Jacques Masquelier began exploring the health benefits of pine bark after discovering its use by indigenous North Americans in treating scurvy and wounds. Since then, pine bark extract has gained popularity as an herbal supplement.
What is Pine Bark Extract?
Origin
Pinus pinaster, commonly known as the maritime pine, is native to regions around the Mediterranean such as Portugal, Spain, France, and Morocco. The bark of these trees, which comes in shades of brown, orange, and red, is thick and robust.
Production Process
To make pine bark extract, the bark is ground, washed, and soaked in hot water. The solid materials are then removed from the liquid extract. This liquid can be used as is or further processed into a powdered form through freeze-drying and grinding.
Common Names and Forms
Pine bark extract is marketed under various trade names, including:
- Pycnogenol
- Oligopin
- Flavangenol
These supplements often contain additional ingredients like vitamin C, other plant extracts, and fillers such as cellulose or glycerin.
Health-Promoting Compounds
Maritime pine bark is rich in beneficial plant compounds, particularly polyphenols, which include:
- Procyanidins: Flavonoids with antioxidant properties, crucial in many medicinal formulations. Pycnogenol, a popular maritime pine bark extract, is standardized to contain at least 75% procyanidins.
- Catechins: Antioxidant-like flavonoids that protect cells from oxidative damage.
- Phenolic Acids: Polyphenols with high antioxidant activity commonly found in plant foods.
These compounds contribute to the extract’s potential health benefits, such as antioxidant, antimicrobial, and anti-inflammatory effects.
Benefits of Pine Bark Extract
Reducing Inflammation
Pine bark extract’s anti-inflammatory properties may help manage chronic conditions like heart disease, diabetes, and inflammatory airway diseases such as asthma and COPD. For instance, a study involving asthma patients found that taking Pycnogenol significantly improved symptoms and reduced reliance on corticosteroids.
Supporting Heart Health
Pine bark extract may promote heart health by reducing oxidative stress, limiting fat buildup, improving venous function, and lowering the likelihood of blood clots. Some studies have shown it can improve cholesterol levels and lower blood pressure, though more research is needed to confirm these benefits conclusively.
Other Potential Uses
Research suggests pine bark extract may have various other benefits, including:
- Promoting healthy aging
- Enhancing wound healing
- Supporting bone health
- Potentially aiding in conditions like Alzheimer’s disease and ADHD
- Improving skin health
- Boosting athletic performance
- Supporting cognitive function
- Helping with erectile dysfunction
How to Use Pine Bark Extract
Pine bark extract is available in various forms, including capsules, tablets, powders, and liquid tinctures. The appropriate dosage can vary based on individual factors like age, body weight, and the specific health condition being addressed.
Conclusion
Pine bark extract, rich in polyphenols like procyanidins, catechins, and phenolic acids, offers promising health benefits due to its antioxidant, antimicrobial, and anti-inflammatory properties. While it shows potential in supporting heart health, reducing inflammation, and more, further research is needed to substantiate specific health claims.
