Listed in Issue 152


DOS SANTOS and others, Faculdade de Ciencias da Saude de Sao Paulo, R. Bartolomeu de Gusmao, Sao Paulo, Sao Paulo, Brazil, have assessed the anti-inflammatory effects of the homeopathic remedy, Rhus Tox (poison ivy).


Homeopathic Rhus toxicodendron (Rhus tox) is used in various inflammatory conditions. The aim of this study was to screen its effect compared to succussed ethanol controls and appropriate active controls.


The potentiations assessed were Rhus tox 6, 12, 30 and 200 cH, using carrageenan-induced paw oedema in rats. The 6 cH dilution appeared most effective and was used in subsequent assays. The authors used pre-treatment and single treatment regimes in Wistar rats and mice.


Significant reductions compared to controls in carrageenan-induced paw oedema, vascular permeability, writhing induced by intraperitoneal acetic acid and stress induced gastric lesions were found.


Rhus tox in homeopathic dilution appears to interfere with inflammatory processes involving histamine, prostaglandins and other inflammatory mediators.
