Synopsis

Source of validity: Traditional
Rating (out of 5): 1

Senna is a herbal laxative traditionally used to treat constipation. Its use in Irritable Bowel Syndrome (IBS) is rooted more in tradition than in scientific evidence, particularly for IBS subtypes characterized by constipation (IBS-C). Historically, senna leaves and pods have been used in various cultures as a remedy for sluggish bowels due to their active compounds called sennosides, which stimulate intestinal motility and promote bowel movements.

However, the evidence supporting senna’s efficacy specifically for IBS is weak. Most clinical studies on senna focus on its laxative effect in general constipation, not IBS. While some IBS patients with predominant constipation may experience relief from senna, there is little direct scientific research on its safety or effectiveness for IBS overall. In fact, its stimulant effect may be too harsh for some IBS patients, potentially causing cramping, diarrhea, or worsening bowel irregularity, especially in those with mixed or diarrhea-predominant IBS.

Major gastroenterology guidelines do not recommend senna as a first-line treatment for IBS. Instead, they typically suggest lifestyle modifications, dietary fiber, or other medications with more established evidence. In summary, senna’s use in IBS is based on traditional use as a laxative, but lacks robust scientific validation for this specific condition.
