We drink kamut green wheat grass periodically as a tonic. And if someone is coming down with something, we all drink it every three hours. It does seem to work for us. Helps to keep us healthy. We rarely get sick. And it seems to reduce the severity and duration if we do. And it helps those in the family who aren't sick, not get it. So good stuff!

Little monkey had the cutest little green mustache. The picture just didn't do it justice.
