Support A Healthy Cardiovascular System With Resveratrol

Chemically, Resveratrol is a polyphenol that includes the flavanoids and proanthocyanadins, both very powerful antioxidants. These are very useful for the destruction of free radicals that threaten your health and well-being in this age of excessive pollution and vehicle emissions, and also excessive exposure to the harmful factors of sunlight through the erosion of the ozone layer that acts as a filter against these harmful free radical-inducing rays.

Biohemically it is a phytoalexin, a chemical used by a plant to protect against and destroy invaders. Each phytoalexin is specific to a particular invader, whether it is an insect, a bacterium or a fungus. They can take the form of terpenes, alkaloids or any other chemical that disrupt the cell walls of or otherwise destroy the enemy to the plant concerned.

Resveratrol is particularly well known for existing on the skins of red grapes, but can also be produced synthetically and marketed as a nutritional supplement. The so-called ‘French Paradox’ relates to the low incidence of coronary heart disease in Southern France in spite of the high saturated fat content of their diet. At least part of this is claimed to be due to the Resveratrol content of the red wine they drink, although the quantity even in a whole bottle is very small.

However, before considering the nutritional benefits of the extract, apart from red grape skins where else can resveratrol be found? Japanese knotweed is a bushy perennial plant, about 4 to 10 feet high, is a very rich source of resveratrol, and is the more important natural source of the two. Red grape skins hardly contain enough to be worthy of extracting. It is also present in minor quantities in pine nuts, peanuts and various other vines and grapes.

It has been under study for many years now for its effect on the heart and other parts of the body, and the antioxidant effect of resveratrol has been found to be unique. The effect of free radicals on the arteries is to help, along with cholesterol, to promote the thickening and hardening of the artery walls. Damage to the arteries by free radicals, and the resulting scar tissue, causes the production of even more free radicals and a vicious circle of damage and even more free radical production occurs.

The antioxidant action of resveratrol is in the enhancement of the nitric oxide content of the blood. Free radicals can reduce the levels of blood nitric oxide that in turn increases blood pressure. An increase in nitric oxide by appropriate antioxidants can help to reduce blood pressure closer to normal. Resveratrol is more effective in achieving this than any of the vitamin antioxidants, A, C or E. It does so by opening up the arteries and reducing the resistance to blood flow through them. .

It also helps to prevent blood cells from sticking together and forming clots that can lead to serious cardiovascular problems, and has been found by Canadian studies to be effective against a much wider range of chemicals that promote blood clotting than any other anti-clotting components of wine. In fact it has now been established, and more or less confirmed by the medical profession, that drinking red wine significantly reduces the effects of cardiovascular disease and can even go a long way towards curing it.

Inflammation is a condition that is caused by the immune system of the body, the purpose of which is to protect us against foreign invaders. However, once inflammation starts, it triggers even further immune responses itself, that if not controlled can lead to extremely painful and sometimes very serious conditions, even after the major trigger for the initial immune response has been dealt with.
