GSE came to prominence as a supplement during the eighties, when the existence of Proanthocyanidins became known to scientists and nutritionists. There are special types of flavonoids that are of significant use to the body because of their properties as antioxidants. This extract was first created by Jacob Harish, a German physicist and researcher who was using it in order to stop the growth of mold on various vegetables and fruits via organic means, rather than using inorganic compounds and chemicals. Not only has it been found useful for these means, it is now utilized by farmers in order to stop mold from becoming prevalent on machinery and tools. It is even used by makeup manufacturers to keep their products well preserved.
