Contractions. - Rhus-rad. Rs-r.
Nat. ord., Anacardiaceae.
It seems still a disputed question whether this differs from R. toxicodendron in anything but habit, Rhus tox. being a dwarf, erect shrub, while R. radicans is a climber. Meantime, since they have been separately proved, and each proving contains symptoms peculiar to itself, it is much the best plan to make tinctures of each and keep them separate. The distinguishing characters of R. radii' cans are the following: -
Stem, from 5 to 40 feet high, furnished with numerous radicles by which it adheres to trees and climbs up them like ivy. Leaves trifoliate and resembling R. toxicodendron in shape, but equally glabrous on both sides and with margins entire.
Preparation. - Tincture, corresponding in alcoholic strength with 40 O.P. spirit.
N.B. - As the plant is not indigenous to this country, the tincture imported from North America must be used.
Reference to Horn. Proving. - Jahr's Symptomen Codex, Hempel's Translation.
Proper forms for dispensing. - φ and upwards, Tincture, Pilules, or Globules.
