Pine bark extract is amazing. Period. It is not only beneficial to humans, but it can drastically benefit dogs and cats of all ages. Pine bark extract can help fight inflammation (arthritis, hip dysplasia and the effects of aging), and it has been shown to improve circulation, immune response, and more. According to their guardians, agility dogs are thriving on it, and senior pets can find relief from the pain and inflammation symptoms of a variety of age related conditions. Pine bark extract has been used by humans in various forms for centuries, and now it is helping dogs and cats in a big way. No matter the age or breed, pine bark extract can be a powerful tool for the well being of your beloved and deserving dogs and cats. To learn all about the benefits of pine bark extract for dogs and cats (and people, too!), read on:


Antioxidant & Anti-inflammatory Effects
Pine Bark Extract protects cells against free radicals, or oxidants. When free radicals react with cells and the DNA they contain, the cells may become compromised, functioning improperly or dying, resulting in numerous health problems, including a weakened immune system. Antioxidants are believed to slow aging and help in preventing chronic illness, including cardiovascular disorders such as heart disease and stroke, inflammatory issues such as arthritis, and neurological disorders such as Parkinson’s and Alzheimer’s. Pine Bark Extract scavenges reactive oxygen and nitrogen radicals, and suppresses production of peroxides in the body.

In the Circulatory System
Pine Bark Extract reduces the permeability and fragility of blood vessels by binding to the collagen in the vessel walls, improving their strength and elasticity. Circulation is enhanced, and blood pressure is reduced. Pine Bark Extract also aids in the production of nitric oxide (NO), a blood gas that enhances blood vessel dilation, increasing blood flow and oxygen supply. Additionally, it lowers LDL cholesterol levels, and reduces platelet aggregation.

Antiviral Properties
Pine Bark Extract also exhibits an antiviral/antimicrobial effect; when applied topically, rate of healing is increases, and scar formation is decreased. This property was likely quite useful to ancient peoples, and is now of benefit in treating viral myocarditis and ulcers.

What conditions may benefit from it?
A) Feline / Canine Arthritis - and other inflammation/mobility issues
B) Feline/ Canine Cancer - and related health issues
C) Feline / Canine Cardiovascular Issues - incl. Coronary Artery Disease
D) Feline / Canine Diabetes - and related issues, Metabolic Disorder
E) Feline / Canine Stroke Victims - and Alzheimer’s, related Dementia
F) Feline / Canine Venous Insufficiency - edema (blood clots), swelling
G) Feline / Canine Health Maintenance - useful in promoting general health

The HISTORY of PINE BARK

     Ancient Chinese herbalists employed pine bark as an anti-inflammatory, used to treat arthritis. Hippocrates briefly mentions its use, in the fourth century, as does Zurich pharmacist Hans Minner, in the Middle Ages, both referring to pine bark as an ingredient in topical wound treatment. European folk medicine has long employed pine bark as a treatment for scurvy. Native Americans used pine bark as food, and as a remedy for inflamed wounds and ulcers. The Iroquois confederacy frequently warred with the nearby Algonquians, and referred to them derogatorily as ‘Adirondacks’, literally, “bark eaters”, for their habit of using pine bark as a nutritional resource! This bit of rival name-calling has entered the common lexicon, attached to the Adirondack Mountain area of upstate New York, as well as a particular style of rustic wooden chair, created and manufactured in the area!

     During the winter of 1535, the French explorer Jacques Cartier, credited with claiming what is now Canada for France, had a fortunate encounter with pine bark. Ice-bound while exploring and mapping the St. Lawrence River, near modern Quebec, his crew developed scurvy, such that, "out of 110 that we were, not ten were well enough to help the others, a pitiful thing to see". Accounts differ as to the specifics, but Cartier’s crew was saved by the advice of a Native American, who instructed them to brew a tea from pine bark and pine needles. Their guide referred to the tree as “Annedda”, and Cartier called it, “l’arbre de vie”, the “tree of life”, for its curative properties.

     In 1732, Carl Linnaeus, considered one of the fathers of modern botany, reported that the Sami people of Northern Europe would hang strips of “fir bark” (Scotch pine) to dry in their barns. If food stores were plentiful, the bark would be fed to their dogs and livestock, but if necessary, they would grind the bark into meal, and use it to bake ‘famine bread’. Bark bread is still found in Finnish cuisine, and elsewhere in Europe.

     In 1951, Dr. Jacques Masquelier, a French chemist, is reported to have read Jacques Cartier’s account of the “scurvy and pine bark” incident, and began examining several sources to identify the bioactive constituents, eventually leading to the extraction of a type of phytochemicals named proanthocyanidins from the bark of the Maritime Pine, a conifer native to Western Europe, found in Portugal, Spain, France, Morocco, and Italy. Masquelier patented his process, naming the compound ‘Pycnogenol.’

ADDITIONAL INFORMATION
Pine Bark Extract is known by several names; the scientific name of the maritime pine, Pinus Pinaster, the bioactive components which are present in the extract; oligomeric proanthocyanidin complexes (OPCs), proanthocyanidin oligomers  (PCOs), condensed tannins, pygenol, etc, and is marketed under the Registered brand name Pycogenol.
OPCs and PCOs are among the simplest flavanols, more complex polyphenols are known as tannins.  Pine Bark has a very high concentration of OPCs; 80-85%, which are also found in apples, berries, chocolate, rhubarb, and other natural sources.

Drug Interactions
- potent antioxidant effect may interfere with the action of anthracyclines, platinum compounds, and alkylating agents
- immunostimulant effect may antagonize the effects of immunosuppressants
- Pine bark extract can inhibit platelet aggregation and may increase risk of bleeding when used with anticoagulant and/or antiplatelet drugs

Of course, even the best pet supplements must be used responsibly - when considering any supplement, medication, or diet change, always consult your health care professional!

    I have been looking at using pine bark from pinebark.com for my 16 year old cat and this is comforting news to read. I certainly want to keep her around as long as I can!
