Wheatgrass is indeed green.  When Dr. Wheatgrass juices the wheatgrass, he makes an extract from it.  The extract is an alcohol process in the same way as other herbal extracts, like echinacea, St. John’s Wort or ginseng, etc.  It is this process that removes the green pigment.  However, we have found that this pigment, “chlorophyll”, is a relatively minor ingredient in the list of therapeutic agents inside this plant.  That is the reason why the Dr. Wheatgrass products are so effective, even though they are not green in color.
