Sweet Gum

Sweet_Gum_jpgTrees in this genus (Liquidambar) are commonly called “Sweet Gum” trees.  They are named for the juices they posses. Sweet Gum is an ornamental and shade tree, good for veneer and plywood.  The gum flows from the tree in the form of bitter-tasting but sweet-smelling balsamic liquid.  It is semitransparent and yellowish-brown, but upon exposure to the air it hardens into a rosin-like hard solid.  The “gum” is chewed by children, the soaked twigs can be used for a toothbrush. In Pioneer times it was used in the South for the treatment of sores and skin troubles and in the treatment of dysentery.  It was favored by the Confederate armies.  During the first World War, and industry for preparing much needed salves arose in Clark County, Alabama.  The Sweet Gum trees were tapped to yield one-half to one pound of resin from each tree.  It was heated carefully, since it is highly flammable, strained and canned. Francisco Hernandez, the first great herbalist of Mexico speaks of it as having leaves “almost like a maple” and a resin of which the “nature is hot in the third order, and dry, and added to tobacco, it strengthens the head, belly and heart, induces sleep and alleviated pains in the head that are caused by colds.”
