History and botany
Slippery elm is a deciduous, understory tree that is native to eastern north america. When healthy, it is a long-lived tree and will tolerate dry spell and partial shade however it prefers sun and moist, limestone-rich soils. It is happiest in riparian forests that grow along the edges of freshwater. Likewise, it’s quite happy when its forest neighbors fall and open the canopy to the sunshine. Along with being a precious herbal ally, slippery elm wood has actually been used to make tools and utensils and the bark can be woven into baskets and mats.
Slippery elms can live up to 200 years and average 60 to 80 feet in height. However, the United States and Canada’s slippery elm trees are presently impacted by a variety of illness that are likewise troublesome for the american elm (ulmus americana), consisting of dutch elm illness and elm phloem necrosis, which is also called “elm yellows” disease. These diseases have actually become so injurious and extensive that slippery elm typically does not have the opportunity to reach full size and old age, and there are few fully grown examples staying. Since there is no useful way to control these illness, the only service is to cut infected elms. Regrettably, by the time symptoms are obvious, it is typically already too late to restore the valuable inner bark.
Stripping the live trees for the medicinal inner bark has also heavily affected the wild populations of slippery elm. In the 19th century, when henry gibson was dealing with american forest trees, he kept in mind that the debarking of slippery elms had actually become common as drug shops and apothecaries produced a need for the dried inner bark. Already in 1913, he was seeing the effect that demand had on the native tree population. “the supply is quickly reducing,” he composed. “the cut for lumber is the primary drain, but a not inconsiderable one is the peeling of trees for bark. This goes on all over the species’ variety and much of it is done by kids with knives and hatchets. It is often hard to discover slippery elms within miles of a town, due to the fact that all have actually succumbed to bark hunters.”.
The removing of live trees for bark continues today and there are increasing instances of slippery elm bark theft on public lands. Gathering from healthy trees, together with lumbering practices in the region, more complicates the outlook for slippery elm because these practices tend to remove the most disease-resistant members of the species, which eliminates their ability to hand down their disease resistance to the next generations.

With this in mind, mountain rose herbs sources slippery elm from only one vendor who gathers bark from a personal organic stand. This single source for slippery elm often suggests we have limited supply, but it is the only source we have discovered that satisfies our uncompromising commitment to sustainable wildharvesting.

The included benefit is that you can grow both of these yourself, so you do not need to depend on wildharvesting. (3 ).
