Larix Americana.

Botanical name: 

The American Larch deserves study, not in combination, as it has been employed, but singly, to determine its real medicinal value. For this purpose a tincture may be prepared from the recent bark, in the proportion of ℥viij. to Alcohol, 30° Oj. It has been employed in combination for a large number of diseases, but its influence upon mucous membranes and upon the skin, is probably most definite.
