in conjunction with the Ulmus aspera, in the form of decoction, and 
in general the effects were very satisfactory. Dr. J. T. Young, who 
I have already quoted, speaks in very high terms of this remedy in 
the cure of hysteria. " I can assert from experience," says he, 
: ' that there is not, in all the Materia Medica, a more certain, speedy, 
and effectual remedy in the hysteria, than the poplar bark, combined 
with a small quantity of laudanum." 
The bark of this tree has of late gained considerable celebrity 
as a tonic, in restoring action to the digestive organs ; also as a val- 
uable medicine given in connexion with the Hydrastus canadensis, 
in restoring weak and debilitated habits. The powdered bark also 
enters largely into the preparation called spice bitters, so universally 
used by the botanic practitioners, as a stimulating tonic. The com- 
position powder so highly valued for the cure of colds, and as a 
diaphoretic, is composed of about one-eighth part of this bark. One 
ounce of the powdered bark, put in one quart of good wine, forms a 
valuable strengthening bitter for female weaknesses and general de- 
bility. 
The poplar bark has been recommended and advantageously 
administered as an anthelmintic. Dr. J. Cost, speaking of this bark, 
says : "The inner bark of the Tulip-tree, or yellow poplar, ZArio- 
dendron tulipifera, is a very good bitter tonic, but is still more valu- 
able as a prophylactic against worms." The bark may be given in 
substance, tincture, infusion, or decoction. In substance, however, 
it acts with most power. The dose of the powdered bark, for an 
adult, is from twenty to one hundred grains. If it produces purging 
and griping, a few drops of laudanum is sometimes added.
