About Slippery Elm:
Slippery elm is a neutral/sweet, gentle and effective remedy for mucous membrane irritations on both the outside and inside of the body. Native American Indians used it as a poultice for wounds, boils, ulcers, inflamed eyes as well as for fevers, cold and bowel complaints. What I love most about slippery elm is that it creates huge amounts of mucilage (boogers) that coats and protects the surfaces. Some of my clients who have used it have complained that it dries out and pulls the skin when used as a poultice but I tell them they need to keep it moist and recommend they spray the wrap with distilled water 2-3 times a day to keep it moistened.
Slippery elm is a native of Canada but lots of it is grown in Michigan, the Appalachian Mountains, Florida and in Texas. It grows on high ground and in dry soil but really likes moist ground as well. These days it’s difficult to find a large specimen tree because they are susceptible to several diseases and harvesting the bark deforms or kills the tree. The inner bark of the trunk and branches are collected in spring.
Actions and Uses of Slippery Elm: (Primary actions are on the nerves, stomach and lungs.)
- Antiseptic (inhibits or kills harmful microorganism on living tissue)
- Demulcent (soothes inflamed mucous membranes and protects them from irritation)
- Diuretic (increases urinary flow and helps to alleviate fluid retention)
- Emollient (an agent used externally to soften and soothe)
- Mild emmenagogue (induces menstruation)
- Mucilage: When the herb comes into contact with inflamed membranes or tissues it soothes, coats, and protects the area and draws out toxins and irritants. Some think there is a reflex action to taking slippery elm orally. It is thought that it may affect the nerve endings in the stomach and intestines to somehow cause secretion of mucous into the urinary tract.
- Nutritive: this is one of Dr. Christopher’s favorite treatments for people who are convalescing or are experiencing failure to thrive and those who are not assimilating nourishment. This pale pink-brown gruel can be mixed with a little honey and cinnamon to make it taste better although it doesn’t taste that bad anyway. Some people also use it as baby food!
- Remedy for lung diseases

Contraindications, safety issues, concerns, harmful drug interactions and allergy precautions for Slippery Elm: Slippery elm is quite safe but because it is so mucilaginous it may interfere with the absorption of medicine if taken at the same time.
Other Notes for Slippery Elm: The American Indians used the bark and as a food called Oohooska meaning ‘to slip’. And, I don’t know how it was used but one resource said that the Indians used the bark as a mechanical irritant and abortifacient to abort half-breed babies when the settlers reproduced with the Indians. Gross. Because of this, the bark is now banned in some countries. This species can be damaged by aphids, caterpillars, gall mites, fungal infections and Dutch elm disease.
Cultivation of Slippery Elm: This Elm can grow 20-50 feet in rich, deep soil in a sunny area. It is hardy to -35 degrees F. It is hardy in zones 3-9. Propagate by sowing the seeds, layering or suckers in the fall or by starting semi ripe cutting in the summer. They can also be grafted. It grows best near streams and other moist areas. The bark is brown and rough outside with thick, soft, yellowish-white, and very mucilaginous bark on the inside. Leaves are opposite, ovate-oblong, taper-pointed, four to eight inches long, doubly serrate, very rough on the top and soft-downy underneath, strongly marked with straight veins. Younger branches and buds look downy. Flowers are reddish, in small and nearly sessile lateral clusters, appearing before the leaves; corolla wanting (whatever that means) and calyx bell-shaped, with seven to nine lobes. The Elm fruit is a one-celled and one-seeded samara, two-thirds of an inch in diameter, the wing extending all around (see picture above). Elm wood is reddish and tough.
