Crude coal tar has long been an effective and safe form of therapy for psoriasis. However, as compounded in an ointment base it has many objectional features and usually is limited to hospital use. A new tar gel has been studied which appears to equal the effectiveness of crude coal tar, is convenient to apply, and is cosmetically acceptable. This new tar preparation is a valuable addition to the therapy of psoriasis.
粗煤焦油长期以来一直是治疗银屑病的一种有效且安全的疗法。然而，制成软膏基质后，它有许多令人反感的特性，通常仅限于医院使用。一种新的焦油凝胶已被研究，它似乎与粗煤焦油的疗效相当，使用方便，且在外观上可以接受。这种新的焦油制剂是银屑病治疗方法中的一项宝贵补充。
