These studies demonstrate that pleuran can decrease the incidence of specific respiratory infection subtypes, can potentially mitigate symptom intensity, and can accelerate recovery time.17, 18, 19 Pleuran also showed potential as an anti-allergic agent in clinical studies that demonstrated a substantial reduction in peripheral blood eosinophilia, a stabilization of total serum IgE levels, and the relief of allergic symptoms after oral administration.20 The gene discussed is IGHE; the disease is respiratory tract infectious disorder.
