Research suggests that aloe vera and its active compounds — including anthraquinones like aloin and the polysaccharide acemannan — show promise for several digestive health applications, particularly as a laxative for constipation and as a potential supportive therapy for inflammatory bowel conditions like ulcerative colitis, with multiple reviews noting encouraging early results that are broadly consistent in direction. Studies indicate that aloe's laxative effects are largely attributed to its anthraquinone content, and some clinical reviews report that aloe vera gel may offer modest benefit in inflammatory bowel disease, with findings occasionally described as comparable to certain standard treatments, though the overall body of evidence relies heavily on narrative reviews, laboratory and animal studies, and small clinical observations rather than large, well-designed randomized controlled trials. The picture is more mixed for irritable bowel syndrome, where at least one randomized controlled trial of 160 patients found no meaningful symptom improvement, and a pediatric review found limited support for aloe in childhood constipation compared to other botanical options. Importantly, safety concerns deserve attention alongside any potential benefits: a documented case report links oral aloe vera capsules to acute hepatitis in an elderly patient, regulatory reviews have associated whole leaf extract with carcinogenic activity in animal studies leading to a Group 2B classification by the International Agency for Research on Cancer, and several reviews caution that anthraquinone compounds carry risks of diarrhea, low potassium, and kidney stress — underscoring that the existing literature, while directionally supportive in some areas, is not yet sufficient to draw firm conclusions about efficacy or long-term safety.
