Eczema belongs to the category of wet sores in Chinese medicine, which is a kind of allergic inflammatory skin disorder, named because the lesions always have wet rotting, oozing and crusting. Damp-heat eczema is mainly manifested as acute onset, short course, reddish lesions, herpes mound, burning itching, scratching oozing and greasy water; accompanied by heartburn and thirst, body heat, dry stools, short and red urine (urine is small in volume and dark yellow in color) and other symptoms. The treatment of damp-heat eczema is based on the principle of clearing away heat and inducing dampness to relieve itching, and it is often treated with the combination of Gentian Liver Tang and Dioscorea Villosa. Commonly used drugs include gentian herb, scutellaria baicalensis, dioscorea villosa, coix lacryma, chen, baixianpi, etc. Severe itching can be added with diclofenac sodium. It is also possible to use heat-clearing and itch-relieving traditional Chinese medicines such as bitter ginseng, cypress, diclofenac seed, thorns, etc. to apply wet compresses in decoction, or to use Sanhuang lotion, glycerite lotion, etc. to apply externally. If the manifestation of damp-heat eczema occurs, you should consult a doctor in time and follow the doctor’s instructions to use medication.
