Parisi, G. et al. 2005. Treatment effects of partially hydrolyzed guar gum on symptoms and quality of life of patients with irritable bowel syndrome. A multicenter randomized open trial

The effects of partially hydrolysed guar gum (PHGG) were compared in a multicentre randomised open trial in patients with irritable bowel syndrome for 12 weeks. Gastrointestinal symptoms, quality of life and psychological symptoms were evaluated and improved significantly after the first month of administration until follow-up compared to those at baseline.
