An atopic dermatitis therapeutic hydrogel is provided to inhibit the moisture release, continuously deliver drugs, adequately absorb percolate, show excellent gel strength, prevent the infection by bacteria and satisfy the storage property and sterilizing effect, thereby being effectively used for atopic dermatitis. A hydrogel for treating atopic dermatitis through irradiation is prepared by a method comprising the steps of: (a) after dissolving 1-50 wt.% of a biocompatible polymer and 1-20 wt.% of a polyhydric alcohol in 1-10 wt.% of at least one extract of a plant medicinal herb selected from the group consisting of Houttuynia cordata, persimmon leaves, Chelidonium majus var. asiaticum, pine needles, Canavalia gladiata, rosemary, lavender, spearmint, chamomile and rooibos, casting the solution; (b) freeze-drying the casted gel at a temperature of -100 to -15 deg.C and thawing it at a temperature of 5-50 deg.C; and (c) applying radioactive rays to the thawed hydrogel to crosslink and sterilize.
