Notable clinical outcomes include reduction in severity score, reduction across various allergic diseases that demonstrated no toxicity, no severe adverse effects, and are well-tolerated. Immunological outcomes that attribute to this include a switch from Th2-mediated allergic response to a Th1/Treg response, characterized by reduced total and specific IgE, total eosinophil counts, and levels of exotoxin, TNF-a, IL-6, IL-8, IL-5, and IL-4, with elevated levels of IFN-γ and IL-10. For eczema, both multiple and single herbal formulations are common treatment modalities, including internal administration and external herbal baths and creams, whereby both provide substantial beneficial outcomes. For EoE, internally administrated formulations and use of acupuncture have been reported and shown mitigation of allergic responses. In FA, formulations have been studied in clinical trials showing consistent safety, with protection remaining to be established. More advanced development of single herbal compounds may provide an advantage for use in FA treatment.
