Re: Problems with hay grown on land prevoiusly planted to ginsen



          The active components of ginseng are saponins called
          ginsenosides. Saponins are poorly absorbed, so most of their
          physiological effects are exerted in the gut. If they are
          absorbed, they cause red blood cell hemolysis, which would
          be evident by the excretion of red urine, due to excretion
          of hemoglobin metabolites arising from the breakdown of the
          rbc. A recent paper " Ginsenosides in roots and leaves of
          American ginseng " J Agr Food Agr 44: 717-720 was published
          by G. Mazza of Ag Canada, Summerland, BC which is just down
          the road from you. His e-mail address is : mazzag@em.agr.ca.
          I have never seen any reports on the toxicity og ginseng to
          livestock. If anyone knows of any, please let me know. I am
          revising my book " Natural Toxicants in Feeds, Forages and
          Poisonous Plants " which has a section on saponins. If
          ginseng is toxic to livestock, I'd like to include reference
          to it. I also suggest that you contact Dave Dyble, Pro Form
          Feeds, Abbotsford, BC. He has some knowledge of ginseng. His
          number is 1-800-663-2267.
                    Hope this is useful.
