People with inflammatory bowel disease could soon be swallowing worms in an effort to relieve their symptoms. Scientists in the United States have developed a drink containing thousands of pig whipworm eggs. Trials suggest it can dramatically reduce the abdominal pain, bleeding and diarrhoea associated with the disease. According to a report in New Scientist, the drink, which is called TSO, could be on sale in Europe by May if it is approved for use by regulators.
