Rhus glabra, R. tryphina, and R. coriaria have acid fruit and astringent bark, which is used in tanning. Rh. g. is a deciduous shrub with stem 2 to 12 feet high, and has terminal flowers, and fruit clothed with acid crimson hairs, like the other non-poisonous Rhoes.
The tincture of the bark was proved by Dr. A. V. Marshall on himself with very substantial doses.
The symptoms of the Schema are his, and they bear out the traditional uses of the remedy. One of these is, “profuse perspiration arising from debility” (Scudder); and Marshall had “profuse sweat during sleep” and such a degree of debility that he was obliged to leave off the proving. Hale mentions that an infusion of the root has a popular repute in diarrhœa and dysentery, especially when the discharges are fetid; and that the berries are used for chronic cough, wheezing cough, and laryngeal asthma.
A tincture made of the whole pannicle (“Sumach-bobs”) cured a patient of his who had every spring an attack of laryngeal cough with dyspnœa and almost complete loss of voice. Farmers place “bobs” in the mangers of horses who have “heaves.”
