A preparation method of the traditional Chinese medicine composition for the treatment of facial acne comprises the following steps: taking cortex phellodendri, cordate houttuynia and/or catechins, and herba ecliptae powder so as to prepare cortex phellodendri filtrate; taking radix scutellariae, a spreading hedyotis herb and/or a chaenomeles speciosa extract, saponins, corydalis amabilis, and radix cynanchi panicullati powder so as to prepare radix scutellariae filtrate; taking rhizoma coptidis, Japanese ginseng powder and/or fructus ligustri lucidi, and paeonia suffruticosa powder so as to prepare rhizoma coptidis filtrate; taking indigo naturalis, Chinese honeylocust fruit and raw sanguisorba officinalis so as to prepare indigo naturalis filtrate; and mixing the cortex phellodendri filtrate, the radix scutellariae filtrate and the indigo naturalis filtrate at weight ratio, so that a water-based traditional Chinese medicine composition is obtained. After the traditional Chinese medicine composition disclosed by the invention is coated, millet-sized to rice-grain-sized follicular keratosis papules on the face disappear, pustules are significantly reduced, and only dark red hyperpigmentation is left, so that the effective treatment rate is over 95%.
