Indian Rhubarb (Rheum emodi), closely related to other Rheum species, has a history of use in traditional medicine, particularly within Ayurveda and Traditional Chinese Medicine (TCM). In these systems, various rhubarb species have been used as herbal remedies for digestive complaints, including constipation and general bowel irregularity. The plant is valued for its purgative (laxative) properties, mainly due to the presence of anthraquinone glycosides such as emodin and rhein. These compounds can stimulate bowel movements by increasing peristalsis and water secretion into the intestines.

There is, however, limited direct scientific evidence specifically evaluating Indian Rhubarb (Rheum emodi) for Irritable Bowel Syndrome (IBS). Most available scientific studies focus on Rheum palmatum or Rheum officinale, and research typically investigates their use for constipation-predominant IBS or general laxative effects. These studies often have small sample sizes or methodological limitations. No major clinical guidelines recommend Indian Rhubarb for IBS, and existing evidence is insufficient to support its efficacy or safety in this context.

In summary, while Indian Rhubarb’s use for digestive complaints, including symptoms that may overlap with IBS, is rooted in traditional practices, scientific validation for its use specifically in IBS is very limited. Caution is advised due to potential side effects (such as dependency or electrolyte imbalance) from prolonged use of anthraquinone laxatives.
