Seeking a treatment for IBS pain in tarantula venom

For patients who have irritable bowel syndrome (IBS), the condition is literally a pain in the gut. Chronic — or long-term — abdominal pain is common, and there are currently no effective treatment options for this debilitating symptom. In a new study, researchers identify a new potential source of relief: a molecule derived from spider venom. In experiments with mice, they found that one dose could stop symptoms associated with IBS pain.
