IGHE and atopic eczema: Research on a ternary compound formula containing ginsenoside Rg1, tetrandrine, and icaritin (GTI) can mitigate atopic dermatitis-like symptoms by reducing the infiltration of eosinophils, mast cells, and CD4+ T cells in skin tissue, as well as reducing IgE-mediated reactions and inhibiting MAPK signaling activation.
