Fighting antimicrobial resistance (AMR): Chinese herbal medicine as a source of novel antimicrobials - an update

B C Millar et al. Lett Appl Microbiol. 2021 Oct.

Abstract

Antimicrobial resistance (AMR) has now emerged as a global public health crisis, requiring the discovery of new and novel antimicrobial compounds, that may be precursors of future therapeutic antibiotics. Chinese Herbal Medicine (CHM) comes with a rich pedigree of holistic and empirical usage in Asia for the last 5000 years. Extracts of Anemarrhena asphodeloides Bunge, Angelica sinensis (Oliv.) Diels, Dianthus superbus L. Forsythiae fructus (Lian Qiao), Lonicerae flos (Jin Yin Hua), Naemorhedi cornu, Platycladus orientalis Franco, Polygonum aviculare, Polygonum cuspidatum, Poria cocos (Schw.), Rehmannia glutinosa (Gaertn.) DC, Rheum palmatum, Salvia miltiorrhiza Bunge, Scutellaria barbata, Scutellariae radix (Huang Qin) and Ursi fel (Xiong Dan) have shown to have antimicrobial properties against clinically significant Gram-negative and Gram-positive bacterial pathogens, as well as the mycobacteria (TB and non-tuberculous mycobacteria). Evidence is now beginning to emerge through systematic reviews of the outcomes of clinical studies employing CHM to treat infections. Of the 106 Cochrane systematic reviews on CHM, 16 (ca 15%) reviews examine CHM in the context of treating a specific infection disease or state. This update examines direct antimicrobial effect of CHM on bacterial pathogens, as well as synergistic effects of combining CHM with conventional antibiotics.

Keywords: Chinese herbal medicine; antibiotics; antimicrobial resistance; antimicrobials; complementary medicine; cystic fibrosis; infection; natural products; pharmaceuticals.
