What is Slippery Elm?
Ulmus rubra (Slippery elm) is a small tree found in Central & Northern US and Canada. The beneficial section is found within the inner bark. The first documentation of slippery elm dates back to Native American tribes who used this plant for skin-related issues.
Historically, slippery elm has been used to help with heartburn, sore throat, flatulence, IBS, and diarrhea, as well as to support urinary tract health. Slippery elm can be used topically for skin care, such as for ulcers, boils, and wounds (11).
Key Components and How It Works
The most important constituents of slippery elm to note are mucilage and tannins. The mucilage is composed of carbohydrates, which form a viscous, sticky substance when added to water.
The inner bark also contains nutrients such as vitamin E and bioflavonoids. The gel-like substance is then used to coat mucous membranes, which may help with coughing, GERD, or other digestive complaints (20).
The tannin properties of slippery elm contain antioxidant and inflammation-modulating activity. Tannins only comprise around 3% of the chemical composition of slippery elm, however, they are a crucial component of this herb. Studies show that slippery elm demonstrates systemic anti-inflammatory and antioxidant activity due to the presence of tannins (20).
Potential Health Benefits of Slippery Elm
Gastrointestinal Support:
Slippery elm is a popular remedy used to support digestive health, including conditions like GERD, gastritis, and IBS, as its emollient and demulcent properties may soothe intestinal mucosa.
In the context of GERD, slippery elm may help coat the lining of the esophagus. The protective coating may support the stomach and small intestine against increased acidity. It can also be used to support digestive health in conditions like ulcerative colitis, Crohn's disease, and diarrhea (18).
Slippery elm is considered useful for individuals with irritable bowel syndrome (IBS) due to its inflammation-modulating and antioxidant properties.
A study conducted on slippery elm, aloe vera, pectin, peppermint oil, and glutamine showed significant improvement in indigestion, nausea, and regurgitation, presenting promising results on the potential benefits of slippery elm for digestive upset (17).
Soothing Sore Throats:
Slippery elm has historically been used to soothe an irritated sore throat. It acts as a soothing agent, especially in spasmodic coughs. The soothing properties stem from the mucilage within the inner bark. The expectorant properties of slippery elm may assist in clearing mucous from the lungs (1).
One study showed that those with a sore throat who consumed slippery elm as a tea reported a reduction in throat discomfort. The study examined other herbs (Licorice) as well (2).
Skin Health:
Slippery elm can be used topically for skin care, such as for wounds, burns, skin inflammation, hemorrhoids, and boils. When applied topically, the inflammation-modulating effects may aid in the healing of damaged skin. The mucilage creates a protective barrier on the skin, allowing the area to heal more effectively. While human studies are limited, promising results show that the use of slippery elm may support wound healing by upregulating enzymes responsible for skin rejuvenation (15).
Additional Considerations:
- Weight Management/Metabolic Conditions: Weight gain can be due to several underlying factors. However, changes in gut microbiota play a significant role in regulating metabolic processes and weight gain. As of now, evidence is anecdotal; however, it suggests that slippery elm may assist in managing blood sugar, which could support weight management (16).
- Cystitis: Slippery elm has occasionally been used to help with discomfort in those with interstitial cystitis. There are currently no studies supporting this; however, many healthcare providers hypothesize that the demulcent properties can soothe the urinary tract in a similar fashion to the digestive tract.
How to Use Slippery Elm
You can purchase slippery elm in the form of capsules, lozenges, or powder to make teas. The most popular method for consuming slippery elm is through decoction.
This involves purchasing the powder and mixing 1 tsp of powder into 1 cup of cold water and letting it sit for 4-12 hours. This method is effective in extracting mucilage and delivers a soothing beverage. This method is often used for soothing a sore throat and supporting gastrointestinal health (13).
Suggested dose of cold decoction tea: ½ cup 2-4x per day
For topical use, slippery elm can be used to make a poultice for skin care, such as for wounds, ulcers, and boils. To make a poultice, mix 1 tsp of powder with enough boiling water to make a paste (13).
Safety and Side Effects
Slippery elm is generally considered a safe herb with minimal side effects and contraindications. Due to the mucilage properties, slippery elm can decrease the absorption of other medications and supplements. It is advised to take slippery elm at least 2 hours away from other medications and foods for best absorption.
Most researchers believe slippery elm is safe during pregnancy and breastfeeding. However, there are no scientific studies to confirm this. Always consult a healthcare provider before starting any herbal supplement during pregnancy or breastfeeding (18).
Comparing Slippery Elm to Other Herbal Remedies
Slippery elm is not the only herbal remedy that contains soothing, demulcent properties. Other herbs with similar properties are marshmallow root and licorice root. Here is a summary of each and its potential benefits:
Marshmallow Root
- Constituents: Mucilage, flavonoids, disaccharides
- Actions: Demulcent, Emollient, Anti-Inflammatory
- Uses: Sore throat, cough, GERD, diarrhea, inflammation of the digestive system
- Evidence: A study conducted on the use of marshmallows for sore throat showed significant improvement in oral and pharyngeal irritation and symptomatic improvement of cough symptoms (14).
Licorice Root
- Constituents: Saponins, flavonoids, isoflavonoids, volatile oils
- Actions: Anti-inflammatory, Mucoprotective, adrenal tonic, demulcent
- Uses: Muco-protective, Anti-ulcer activity, Anti-viral, Anti-Inflammatory, Anti-bacterial
- Evidence: Licorice can help soothe the digestive and respiratory tracts, similar to slippery elm. Due to its high flavonoid content, licorice can be used to coat the stomach in patients with gastric ulcers. In addition, Licorice has anti-bacterial properties that are effective against H. pylori, the causative agent for most ulcers (23).
