Green Tea Leaf Extract
In recent years, the health benefits of consuming green tea, include the prevention of cancer and cardiovascular diseases, and the anti-inflammatory, antiarthritic, antibacterial, antiangiogenic, antioxidative, antiviral, neuroprotective, and cholesterol-lowering effects of green tea. The health-promoting effects of green tea are mainly attributed to its polyphenol content, particularly flavanols. Recently, many of the aforementioned beneficial effects of green tea were attributed to its most abundant catechin, (-)-epigallocatechin-3-gallate (EGCG). In general, herbal medicines are complex mixtures of different compounds that often act in a synergistic fashion to exert their full beneficial effect.
