Figure 3: An illustration of SHU formula intervening the influenza development through multiple pathways. The blue rectangle is bioactive herbal compounds derived from SHU formula. The ellipse represents biological pathways that the compounds modulate. The red ones are literature-verified pathways that participate in the process of influenza infection, while the gray ones are not verified yet. A thick edge indicates many common hits (pathway components that are also associated targets of herbal compounds) between two pathways or between a compound and a pathway.
