History and discovery of Grape Seed Extract?
Grapes were first cultivated near the Caspian Sea, and their use as food and drink had spread throughout the Mediterranean world before the Bible was written.
The ancient Greeks believed that wine had wonderful health benefits, and modern science has confirmed that wine has many useful properties. While the benefits of wine may be tarnished by the devastation associated with alcohol abuse, the positive aspects of grape seeds have no such liability.
Vitis vinifera. The first recorded mention of a key ingredient in grape seed extract was in 1534 in the mission logs of Jacques Cartier as he was exploring the St. Lawrence River. It seems he and his men became ice-bound during a particularly bitter Canadian winter. His men had begun suffering from scurvy when a friendly native happened by and taught them how to make a tea from pine bark that produced an immediate improvement in the crew's health.
Jacques Masquelier, upon reviewing Cartier's logs, felt that there must be a rich source of Vitamin C in pine bark, and went about investigating the possibilities. What he found were other substances he called oligomeric proanthocyanidin complexes (OPCs) and procyanidolic oligomers (PCOs). Masquelier patented the method of extracting PCO from pine bark in France in 1951 and gave it the trade name Pycnogenol. In 1970, he was successful in extracting PCOs from grape seeds. Sales in France of the grape seed extract are 400 times greater than those of the more expensive pine bark products. Other sources rich in PCOs are cranberry, blueberry, bilberry, hawthorn berries, black currants, green and black teas, and red wine. From any source, these plant flavonoids seem to exert a number of health-promoting effects.
People have been using grapes since ancient times not only for eating and drinking but for medicinal purposes as well. Different parts of the plant including the grapes themselves, the leaves, and the stems, have been used. It was not until the 1970's when a French biochemist isolated from grape seed the substance called oligomeric proanthocyandin (OPC). This substance was said to improve blood circulation and to have some protective properties against heart disease.
The world have published much of the research on grape seed extract, but ironically grape seeds were a "second choice." Manufacturers turned to using grape seeds only when peanut skins became unavailable.
Important differences between Grape Seed and Pine Bark:There are some important differences.
Antioxidant advantage: In the words of Professor Masquelier, developer and patentee of both OPC products announced: . . ."I underline that in 1986 I discovered that grape seed has an intense free radical scavenging effect (FRSE) on radical oxygen species. These discoveries were laid down in my U.S. Patent (no 4,698,360) of Oct. 6 1987, 'Radical Scavenging Effect of Proanthocyanidins' . . . The tests showed that in this respect OPC from Grape seed has an advantage over OPC from Pine bark. OPC from grape seed contains the gallic esters of proanthocyanidins (in particular: Proanthocyanidin B2-3'-O-gallate). These proanthocyanidins -esters have been recently described as the most active substances in the battle against free radicals." October 1991 Martiliac, France (Procyanidines de France). Independent research by Dr Ricardo Da Silva showed "Proanthocyanidin B2-3'-O-gallate" available only in grape seed was found the most effective compound in trapping free radicals.
Strength: Pycnogenol (Pine tree) has an OPC strength ranging from 80-85% compared with Grapeseed normally marketed at 90-95%. Be careful that the Grapeseed is 95%. A slight difference in favour of grapeseed. Research points toward the fact that proanthocyanidin 100% purity is non-mutagenic. Thus the range 90-95% for maximum benefit.
