An assessment of high and low temperature tars in Psoriasis.
Comparison of the efficacy of crude coal tar from high and low temperature sources in the treatment of patients suffering from chronic psoriasis showed the tars to be equally effective. High temperature tar was then compared with standard refined tar. Again, an equal therapeutic response was achieved. Crude coal tars obtained by the carbonization of coal in coke ovens and in smokeless fuel manufacture can be employed in dermatological therapy in place of the dwindling supplies of crude tar of gasworks origin.
