Encyclopedia of Natural Medicine by Michael Murray and Joseph Pizzorno, page 593:
"Researchers investigating ulcerative colitis often use carrageenan (a compound extracted from red seaweeds) to experimentally induce the disease in animals. In the initial experiments reported by Marcus and Watt in 1969, one-percent and five-percent carrageenan solutions were provided as the exclusive source of oral fluids for guinea pigs. Over a period of several days, the animals lost weight, developed anemia, had bloody diarrhea, and developed ulcerative colitis. These results have since been confirmed by numerous investigators and in studies involving diverse animal species, including primates."
