Small magnolia (Magnolia glauca)
"The Magnolia glauca belongs to the class of tonic bitters, and is far from being an unimportant article of this useful set of medicines. The bark of the roots of this tree have an aromatic odour and a bitter taste; and a decoction is said to have been very useful in rheumatic affections. […] It is said that the root is used as a bait to catch the beaver, that animal being fond of it as food […] The tree may be propagated by seeds; and it is said, I know not with what foundation, that those sent from this country to Europe, will not vegetate without being passed through the alimentary canal of the turkey."
