Liquidambar Styraciflua. (Sweet Gum.)
Some years since we had sweet gum, the exudation from this tree, recommended for the cure of asthma, and a number of cases from the South were given as proof. But experiments in the Northern States were not favorable. I judge, however, from some reports of Southern physicians, that the recent bark contains valuable medicinal properties, as does the fresh exudation. For experiment I would suggest the preparation of a tincture from the fresh bark, using Alcohol of 76°. Its influence is probably most marked on mucous membranes, and probably it influences innervation from the pneumogastric and from the spinal cord.
