Was ist Slippery Elm?
Slippery elm is a native elm of eastern and central North America. Its inner bark — the pale layer beneath the rough outer bark — becomes slick and gel-like when wet, thanks to its high mucilage content. Native American peoples used it for wounds, sore throats and as a food in lean times, and settlers adopted it widely; lozenges and bark gruels were staples of American home remedies into the 20th century.
Like marshmallow root, it is a demulcent: the mucilage coats and soothes irritated tissue. The US FDA has recognised it as a safe demulcent ingredient in throat lozenges. Beyond that, clinical research is very limited — mostly small studies of mixed-herb products for digestive complaints — so much of its reputation rests on tradition and a plausible mechanism.
Wirkung & Anwendungsgebiete
Soothes a sore throat
The most accepted use. Lozenges and warm bark drinks coat the throat and ease the rawness of a cold or overuse. Relief is local and temporary, but real.
Gentle on an irritated stomach
Traditionally used for heartburn, gastritis-type discomfort and as an easily digested food during recovery. Human evidence is thin; the coating effect is the likely explanation.
Bowel comfort
Used in some herbal blends for irritable bowel symptoms and constipation. A couple of small studies of combination products showed improvements, but it is impossible to credit slippery elm alone.
Traditional poultice
Moistened bark powder was applied to boils, burns and wounds. There is no modern evidence, and clean modern dressings are better for broken skin.

Lozenges
The simplest route for a sore throat. Suck slowly, following the label.
Gruel
Stir 1 tbsp powdered inner bark into a little cold water to make a paste, then whisk in a cup of hot water or milk. Sweeten with honey or add cinnamon. Up to 3 times daily.
Tea
1–2 tsp powdered or shredded bark in a cup of hot water, steeped 5–10 minutes. It will be thick and cloudy — that is the mucilage.
Drink plenty of fluid
Always take the powder mixed with plenty of liquid, as it swells considerably.
Consider an alternative
Marshmallow root does much the same job and is easily cultivated. It is a good swap if you are concerned about sustainability.
⚠️ Vorsichtshinweise
- Other medicines: the mucilage can slow absorption of medicines taken at the same time. Take slippery elm at least an hour before or a couple of hours after any tablets.
- Pregnancy: whole bark was historically misused to cause miscarriage. Powder taken by mouth in food amounts is generally regarded as low-risk, but there is no safety data — ask your midwife or doctor first, and avoid it while breastfeeding unless advised.
- Allergy: people sensitive to elm pollen may react, and handling the bark can cause skin irritation.
- Choking risk: dry powder swells, so never swallow it dry and give it to young children only as a well-mixed thin gruel.
- Sustainability: harvesting the inner bark often kills the tree, and wild elms have already been devastated by Dutch elm disease. Conservation groups list slippery elm as a species to watch — buy from suppliers who harvest responsibly, or choose marshmallow root instead.

Häufige Fragen
Why is it called "slippery"?
Because the inner bark feels slimy when wet — chew a strip and it becomes slippery in your mouth. That slipperiness is the mucilage doing its work.
Can it help acid reflux?
Some people find a gruel soothing, and it is a traditional choice. There is no solid evidence it heals the oesophagus, so persistent reflux needs a doctor's review.
Is it safe for children?
Lozenges and a thin gruel are traditionally given to older children. Check with a pharmacist first, and avoid lozenges in children too young to suck them safely.
