The herbal remedies provided by nature are an amazing aspect of our planet, and slippery elm is no exception. Formally known as Ulmus rubra (or fulva), the inner bark of the elm tree has been used in North America for centuries. Its name stems (no pun intended) from the fact that the bark consists of mucilage, which creates a slick substance when mixed with water. Native Americans used it as a healing salve for sores and wounds, as well as for GI issues and flu-like symptoms. Today, slippery elm is used to treat a variety of ailments from healing digestive distress to soothing stress and anxiety to treating symptoms of psoriasis. Studies are even showing the herb has its benefits for women who are undergoing treatment for breast cancer.

Aside from the mucilage, slippery elm is also packed with nutrients. It is not only a potent source of antioxidants but also contains a host of minerals, such as magnesium, iron, calcium, potassium, as well as vitamin C and a family of B vitamins, to name a few. It's no wonder that this herb provides a powerful medicinal punch! I use the herb regularly in my practice—here is what you need to know about its benefits, how to buy it, its safety record, and its side effects.

How you can experience slippery elm's benefits.

Slippery elm comes in many forms, and can be found online, or at your local health food store or natural market. It is typically sold as a powder, capsule, tea, or tincture. The way in which you will use it will depend on your treatment needs, but the most common way to consume slippery elm is either as a supplement or tea.

How slippery elm helps with constipation and digestion.

Slippery elm has been shown to relieve symptoms of digestive issues across the board, from heartburn and gastroesophageal reflux disease (GERD), to irritable bowel diseases, such as Crohn's, ulcerative colitis, IBS, and diverticulitis. Specifically, slippery elm is a demulcent, meaning it has the capacity to coat mucus membranes in the esophagus, stomach, and intestines. This not only helps to move things along but also works to calm inflammation and irritation in the digestive tract. In one study, when IBS sufferers were given a mixture containing slippery elm, they experienced a reduction in the severity of symptoms like diarrhea, constipation, abdominal pain, and bloating. Another study attributes the herb's ability to soothe IBS symptoms to its high antioxidant content.

If you feel as if slippery elm is just what you need to nourish your digestive system, I recommend drinking it in tea form, or try this comforting gut-healing pumpkin porridge. The slippery elm together with the gelatin makes this a very digestive-friendly (and fall-flavored) dish!

Gut-Healing Pumpkin Pudding

Serves 4


  • 1 15-ounce can pure pumpkin puree
  • 1 can full-fat coconut milk
  • 2 to 3 tablespoons coconut nectar, honey, or maple syrup
  • 1 teaspoon vanilla extract
  • 1 tablespoon cinnamon
  • 2 teaspoons pumpkin pie spice
  • 1 inch grated ginger
  • 2 tablespoons slippery elm powder
  • 2 tablespoons gelatin, dissolved in ¼ cup boiling water


  1. In a high-speed blender, add coconut milk, pumpkin, liquid sweetener, vanilla, cinnamon, pumpkin pie spice, and ginger. Blend for about 10 seconds until creamy. Add slippery elm powder and blend again.
  2. Prepare the gelatin. In a small bowl, add gelatin and boiling water. Stir vigorously with a fork until completely dissolved (if you end up with some chunks, that's OK). Add to blender. Process again.
  3. Pour into bowls or Mason jars. Allow to set in the fridge for at least 6 to 8 hours or preferably overnight.

How slippery elm can help soothe a sore throat.

Slippery elm can also be used for upper respiratory issues like cough, sore throat, laryngitis, and tonsillitis. The demulcent effect works the same way it does in the digestive tract: The mucilage coats the throat, which calms irritation while antioxidants fight inflammation. If you are struggling with a sore throat, or needing to soothe other symptoms of the common cold, there are teas and lozenges on the market that can help. If you want to get creative in the kitchen, make your own lozenge! This recipe contains slippery elm in powder form, as well as Manuka honey, which comes with its own sore-throat-soothing powers.

  1. Place the Manuka honey in the fridge for at least 30 minutes to chill.
  2. Roll a teaspoon of the honey in the slippery elm powder to form a little ball.
  3. Transfer to a plate and continue until all honey is used. Allow the lozenges to harden in the freezer. Store in the freezer as well.

How slippery elm can help with bladder health.

Slippery elm is sometimes used as an alternative treatment for urinary tract and bladder infections. While more evidence is needed to support this claim, the demulcent effect of the mucilage, when taken orally through tea or tincture, could calm the irritation and inflammation brought on by bladder infection and UTIs.

How slippery elm can help with stress and anxiety.

Given that our mental health is largely tied to our digestive system, it is no surprise that slippery elm's gut-healing effects can help to reduce anxiety and relieve stress. Additionally, slippery elm contains plant phenolic compounds, which studies have shown support both physical and mental health, and can even naturally protect against stress. If you are curious to see if slippery elm could help you in this capacity, I recommend consuming the herb in its powder of tincture form.

How slippery elm helps with symptoms of psoriasis.

One study found that when participants consumed slippery elm water with a real food, nutrient-dense dietary regimen, the severity of their psoriasis symptoms improved. There currently is no cure for psoriasis, and therefore it is a skin disorder that must be managed. While the cause of psoriasis is still unknown, research concludes that a disruption in immune function plays a role. Since elm bark contains immune-protective properties, this has positive implications for treatment. It seems as if drinking slippery elm tea or water could be beneficial; however, more research is needed to confirm the correlation.

How slippery elm could potentially help in breast cancer treatment.

Slippery elm has become a part of a popular herbal remedy for breast cancer patients. Essiac, which combines slippery elm with a blend of burdock root, Indian rhubarb, and sheep sorrel, is often administered to women with breast cancer to help improve their symptoms. One study reports numerous women felt the beneficial effects of Essiac, which research shows contains antioxidant and anti-cancer activity.

Does slippery elm have any side effects?

While there are no reported serious side effects, more research is needed to explore the efficacy and safety of slippery elm, given that there is still unsubstantiated evidence to support its use. Before adding this herb to your diet or natural remedy regimen, there are a couple other points to consider. Since slippery elm gels coat the lining of the digestive tract when ingested, the mucilage could prevent the absorption of other medications. Furthermore, slippery elm has been said to potentially trigger miscarriage, so it is not recommended to consume while pregnant. I advise speaking to a health care professional to determine if slippery elm is right for you.
