This study reports significant improvement of atopic dermatitis condition as a result of experiment using Xanthium strumarium L. extract (XS-E) at the dorsal skin of induced atopic dermatitis Nc/Nga mice. Skin clinical score has decreased (2.75±0.85, *p<0.05), showing visible change of skin condition. IgE (***p<0.001) and IgG1 (2522.00±32.80, ***p<0.001) in plasma also decreased significantly. mRNA (gene expression) level increased (RQ=2.75±0.10, ***p<0.001) within skin tissue of

Upon examining cells permeated with H&E and toluidine blue staining technique, thickness of epidermis and mast cell's permeation decreased, and the result of examining the distribution of CCR 3+ eosinophils within ALN showed that it's level fell down to that of wild type (normal group, NC/Nga-WT). By such results, it is suggested that XS-E is highly effective on atopic dermatitis, and it is considered that continued quantitative research and case study of clinical research such as effect of cell number in individual tissues or change of total cell number are necessary.
