Typically concentrated in the bark of trees and in the outer shells of seeds, proanthocyanidins help protect plants against oxidative elements such as oxygen and sunshine. One of the richest sources of proanthocyanidins in nature is grape seeds. Recent studies in animals, as well as some human studies, have shown that grape seed proanthocyanidin extracts possess a broad spectrum of biological, pharmacological and chemoprotective properties against free radicals and oxidative stress. Some grape seed extracts have also been reported to promote collagen formation, enhance cardiovascular health and improve microcirculation. There is a growing body of scientific evidence to suggest that proanthocyanidins are far more powerful antioxidants than vitamins C, E or beta-carotene and that they may prevent many of the effects related to premature aging and protect the body\u2019s cells against the toxic effects of drug induced, chemical and environmental pollutants.<\/p>\r\n  <p>Another polyphenol naturally present in grape seeds is resveratrol, which is being investigated for its possible effect on cancer cell growth, proliferation or apoptosis (programmed cell death) of cells, and other potential chemopreventive mechanisms.<\/p>\r\n  <p>Preliminary research using disease models is investigating the beneficial properties of grape seed extract for the treatment of :\r\n    <ul class=\"noline\">\r\n      <li>Skin and wounds \u2013 induced vascular endothelial growth factor and accelerated healing of injured skin in mice.<\/li>\r\n      <li>Teeth \u2013 seed phenolics may inhibit oral sugar metabolism and retard growth of certain bacteria that cause dental caries.<\/li>\r\n      <li>Bones \u2013 grape seed extracts enhanced bone density and strength in experimental animals.<\/li>\r\n      <li>In vitro cancer studies \u2013 grape seed proanthocyanidins for decreasing tumor numbers and reducing the malignancy of papillomas.<\/li>\r\n      <li>Ultraviolet damage \u2013 dietary proanthocyanidins are under study for mechanisms against carcinogenesis and for sunscreen protection.<\/li>\r\n      <li>Anti-viral effects.<\/li>\r\n      <li>Liver function.<\/li>\r\n      <li>Blood flow and fluid balance.<\/li>\r\n    <\/ul>\r\n  <\/p>\r\n  <p>The potential for beneficial effects of grape seed extracts in human disease and health issues has been studied in a number of controlled clinical trials, in particular conditions such as breast cancer, and cardiovascular diseases and health issues such as post menopausal hormonal imbalance.<\/p>\r\n<\/div>\r\n<div class=\"details_box\">\r\n  <b>References<\/b>\r\n  <ol class=\"reference\">\r\n    <li>Joshi SS; Kuszynski CA; Bagchi D.
