Chlorophyll has protective and regenerating effect on the liver.
Other than the hundred types of enzymes that wheatgrass supplies (exogenous enzymes which means from outside source), the indole part of the chlorophyll supports production of enzymes by the body (endogenous). These enzymes detoxify carcinogenic substances that can cause liver cancer. The liver also uses theses enzymes to carry out its function as the detoxifying organ of the body.
Three compounds found abundantly in wheatgrass help the liver stay vital and healthy. Choline prevents deposition of fats in the liver, magnesium helps draw out excess fats in the liver and potassium acts as invigorator and stimulant.
