Chlorophyll is one of the most important natural compounds. Like a small, green power station it incessantly transforms sunlight into energy. This metabolism in plants is known as photosynthesis.
In 1909 French scientists first called the green colouring of leaves chlorophyll (Greek: chloros = green, phyllos = leaf). It has been known since 1851 that chlorophyllin is chemically related to hemin, the red coloring in blood. Since then the various effects have been studied in a series of scientific examinations. The oral use of chlorophyllin resulted in a decreasing resp. dimishing of penetrant body and mouth odour.
