Chinese herbal medicine has built up a sophisticated system for treating skin disorders, using both external and internal administration. There are hundreds of herbal formulas available for skin conditions such as herpes, eczema, and psoriasis
Extensive modern pharmacological research has been done on the herbs in this formula in regard to their effectiveness as antibacterial, antiviral and anti-fungal agents. The antibiotic effect of skullcap (Huang qin) has been confirmed to be effective against many pathogenic bacteria includingStaphylococcus aureus, Streptococcus pneumonia, Corynebacterium diphtheriae, Pseudomonas aeruginosa, and Neisseria meningitides. Clinical research indicates that philodendra (Huang bai) are very effective in treating eczema around the ears; and local external application of rhubarb (dai Huang) is effective in the treatment of stomatitis, oral ulcers, and folliculitis, especially those caused by Staphylococcus aureus. Decoctions of sophora (ku shen) have an in vitro inhibitory effect against common dermatomycoses (fungal infections).
