Overview

Rhubarb (Rheum officinale) is a plant. Its stalk is commonly eaten. Its root and underground stem are used in traditional Chinese medicine combinations.

Rhubarb contains chemicals that might help heal cold sores and reduce swelling. Rhubarb also contains fiber, which might help reduce cholesterol levels and affect stomach conditions.

People use rhubarb for diarrhea, stomach pain, indigestion, symptoms of menopause, menstrual cramps, obesity, swelling of the pancreas, and many other conditions, but there is no good scientific evidence to support most of these uses.

Uses & Effectiveness ?

Possibly Effective for

  • Symptoms of menopause. Taking a rhubarb root extract by mouth seems to improve symptoms of menopause, including hot flushes, mood, quality of life, and fatigue.
  • Swelling (inflammation) of the pancreas (pancreatitis). Taking rhubarb by mouth or rectally might help reduce pain and other symptoms of pancreatitis. It might also reduce the length of a hospital stay for pancreatitis.
There is interest in using rhubarb for a number of other purposes, but there isn't enough reliable information to say whether it might be helpful.
