💊 Profile

Rhus consists of the dried fruits of the smooth or Pennsylvanian sumach, Rhus glabra (Anacardiaceae). It has astringent and reputed diuretic properties. R. aromatica has been used similarly to R. glabra. Poison ivy (R. radicans) and poison oak (R. toxicodendron), species growing in the USA, contain irritant poisons, such as urushiol, that produce severe contact dermatitis. Extracts of poison ivy and poison oak have been used for the prophylaxis of poison ivy dermatitis but their effectiveness has not been proved. The spice sumac is prepared from the berries of R. coriaria.


Some Rhus spp. are used in homoeopathic medicine. Poison oak has been used in homoeopathic medicines under the following names: Toxicodendron quercifolium; Rhus toxicodendron; Rhus. tox.
