Ko et al. examined nine Chinese traditional medicines that are typically used in inflammation and viral infection and found that A. paniculata extracts showed the greatest potency in inhibiting the secretion of RANTES, a chemotactic cytokine, in influenza A virus (H1N1)-infected human bronchial epithelial cells (A549) with an IC50 of 1.2 ± 0.4 μg/m [147]. Here, CCL5 is linked to viral infectious disease.
