Grass juice is a very powerful cleanser of the body in general.The skin is an elimination avenue of the body and over half of the bodies solid waste goes out this way.Skin conditions are a sign of internal issues and overwelmed elimination pathways.if the bile is full of waste and you take a shot of grass you will eject the bile.Opening up the elimination pathways should be done before one uses high power cleansers so things will be less violent.I consume 6-12ozs. of barley juice and have no problem at all,except for growing issues.I have pictures of my grass in the Image Gallery in the photos section under grassmans sprouts.Are you growing your own grass and if so is mold an issue?Jeff.
