Pine bark (Pinus pinaster)
Synopsis of pine bark
Pine bark extract, most commonly derived from the Pinus pinaster tree (French maritime pine), is a concentrated source of powerful antioxidants, particularly oligomeric proanthocyanidins (OPCs). These flavonoid compounds are known for their ability to scavenge free radicals, reduce inflammation, and support vascular health. One of the most widely studied standardized extracts is Pycnogenol®, a patented form of pine bark extract from French maritime pine.
Medicinally, pine bark extract is used to support circulation, improve skin elasticity, reduce chronic inflammation, and enhance cognitive function. It is also widely studied for managing high blood pressure, blood sugar control in diabetes, and symptoms of ADHD. OPCs in pine bark help stabilize collagen and elastin, making them beneficial for skin health, joint function, and wound healing.
Pine bark’s cardiovascular benefits stem from its ability to strengthen blood vessels, improve microcirculation, and reduce oxidative stress in the endothelium (the lining of blood vessels). It also exhibits anti-viral, anti-bacterial, and immune-modulating properties. As a supplement, it is commonly available in capsules or tablets, with standardized OPC content to ensure consistent therapeutic value.
Historical Use in Medicine:
The medicinal use of pine bark dates back centuries and is rooted in multiple traditional systems. One of the earliest recorded uses came from Native American and First Nations peoples, who used pine bark infusions and poultices for respiratory infections, scurvy, wounds, and inflammation. The bark of various pine species was boiled into teas or ground into pastes and applied topically.
A key moment in pine bark’s historical medicinal relevance occurred in the 1530s when French explorer Jacques Cartier’s crew suffered from scurvy during a harsh Canadian winter. Indigenous peoples advised them to drink a tea made from pine bark and needles, which likely provided vitamin C and flavonoids, helping to reverse symptoms. This event helped spark European interest in the medicinal properties of pine trees.
In traditional European herbalism, pine was used as a remedy for bronchitis, sore throats, rheumatism, and urinary tract infections. The resin and bark were included in tonics and salves for their antimicrobial and anti-inflammatory properties.
Modern research into pine bark extract began in earnest in the 20th century, with the development of standardized extracts like Pycnogenol. Clinical studies since then have validated many traditional uses, particularly in cardiovascular health, diabetes management, and skin aging. Today, pine bark is considered a well-researched botanical with a diverse range of applications in integrative and preventative medicine.
