Chinese herbal medicine (CHM) addresses complex diseases through polypharmacological interactions.However,systematic studies of herbal medicine pharmacology remain challenging due to the complexity of CHM ingredients and their interactions with various targets.In this study,we aim to address this challenge with computational approaches.We investigated the herb-targetdisease associations of 197 commonly prescribed CHMs using the similarity ensemble approach and DisGeNET database.We demonstrated that this method can be applied to associate herbs with their putative targets.In the case study of three well-known herbs,Radix Glycyrrhizae,Flos Lonicerae,and Rhizoma Coptidis,approximately 70％ of the predicted targets were supported by scientific literature.By linking 406 targets to 2439 annotated diseases,we further analyzed the pharmacological functions of 197 herbs.Finally,we proposed a strategy of target-oriented herbal formula design and illustrated the target profiles for four common chronic diseases,namely,Alzheimer’s disease,depressive disorder,hypertensive disease,and non-insulin-dependent diabetes mellitus.This computational approach holds great potential in the target identification of herbs,understanding the molecular mechanisms of CHM,and designing novel herbal formulas.
