The inner bark of this tree is an article of much value, and may be used to advantage in many different ways. There are several species of the elm that grow common in this country, and there are two kinds of the slippery elm. In one the bark is rather hard and tough, and the other is very brittle; the latter is the best for medicinal uses. The bark should be peeled, the outside rind shaved off, dried, and ground or pounded to a fine powder. If used internally, put a teaspoonful of this powder into a teacup with as much sugar, mix them well together, then add a little cold water and stir it until perfectly mixed, and then put hot water to it and stir till it forms a jelly thick enough to be eaten with a spoon. A teacupful may be taken at a time, and is an excellent medicine to heal soreness in the throat, stomach and bowels, caused by canker; or more hot water may be put to it and made into a drink and freely taken for the same purpose. I have always made much use of this bark for poultices, and have in all cases found it a most excellent article for that purpose. Mixed with pounded cracker and ginger it makes the best poultices I have ever found; for burns, scalds, felons, old sores, etc., it is the best thing that can be used to allay the inflammation, ease the pain and heal them in a short time.

With Lobelia, it forms an excellent poultice for abscesses and boils.

In constipation, dysentery, diarrhoea and cholera infantum, used both internally and per rectal injection, it soothes and relieves the intestinal irritation. It is a nutritious demulcent, soothing to the mucous membrane wherever needed and quieting to the nervous system. In diphtheria, after the throat has been ridded of the decayed membrane, it is quite raw, also during the scaling process in scarlatina and measles and at times in typhoid fever; slippery elm is then a very important agent.
