The invention relates to a Chinese medicinal composition for preventing and treating
seborrheic dermatitis, which comprises the following raw medicines in portion by weight: 20 to 50 weight portions of
pseudolarix, 25 to 45 weight portions of kuh-seng, 10 to 20 weight portions of clove, 10 to 20 weight portions of cinnamon, and 30 to 60 weight portions of Cacumen Platycladi. According to clinical observation and experimental
verification, the Chinese medicinal composition can effectively prevent and treat the
seborrheic dermatitis. After two weeks treatment, symptoms such as
erythema, pruritus and scale are improved markedly, and
statistical analysis shows that the total effective rate of the tested medicament is 75.24 percent and the total effective rate of the contrasted medicament (Caile
lotion, Xian Yangsen Pharmaceutical Ltd.) is 58.10 percent; and after four weeks treatment, the total effective rate of the tested medicament is 85.71 percent, and the total effective rate of the contrasted medicament is 65.71 percent, so that the
treatment effect of the tested medicament is obviously higher than that of the contrasted medicament. The
relapse rate of the
seborrheic dermatitis is only 1.9 percent within one month after the medicament of the invention is stopped, and is low compared with 5.7 percent of the
relapse rate of the contrasted medicament; and no allergic symptom occurs during the
