Slippery Elm powder is made from the inner bark of the Ulmus rubra and Ulmus fulva tree. It has three main actions in the body. It is a demulcent (soothing effect on the mucus membranes), an emollient (soothe, soften or protect skin) and a laxative (helps facilitate bowel movements). Slippery Elm places a soothing coating on the membranes of the digestive system, helping to heal inflammation and making it a valuable herb for the gut. Slippery Elm powder should be taken with plenty of water. The powder does have a tendency to float, a bit like cinnamon, so mix 1 teaspoon with a small amount of water or yoghurt to make a runny gruel and take this followed by a glass of water. If using for gastritis or peptic ulcer slippery elm should be taken before meals. If using for gastro-oesophageal reflux take after meals and before bed. A larger dose may be necessary if using to help with constipation or anal fissure. In the case of diarrhoea, slippery elm supplies an increase in dietary fibre plus absorbs toxins and aids in balancing of good gut flora.
