Has anyone heard of a human poisoned by a Sago Palm? My husband spent over 5 hrs. up under our huge plant trimming all the lower branches. The next day he began running a fever, which has lasted 4 wks. He is now in the hospital with an infected, inflammed colon, extreme nausea, diarhea with blood and he is not responding to antibiotics. We are wondering if this could be the source. Thanks
