The comparison between traditional Chinese medicine Jinzhen Oral Liquid (JZOL) and western medicine in treating children with acute bronchitis (AB) showed encouraging outcomes. This trial evaluated the efficacy and safety of the JZOL for improving cough and expectoration in children with AB. 480 children were randomly assigned to take JZOL or Ambroxol Hydrochloride and Clenbuterol Hydrochloride Oral Solution for 7 days. The primary outcome was time-to-cough resolution. The median time-to-cough resolution in both groups was 5.0 days and the antitussive onset median time was only 1 day. This head to head randomized controlled trial showed that JZOL was not inferior to cough suppressant and phlegm resolving western medicine in treating cough and sputum and could comprehensively treat respiratory and systemic discomfort symptoms. Combined with clinical trials, the mechanism of JZOL against AB was uncovered by network target analysis, it was found that the pathways in TRP channels like IL-1{beta}/IL1R/TRPV1/TRPA1, NGF/TrkA/TRPV1/TRPA1 and PGE2/EP/PKA/TRPV1/TRPA1 might play important roles. Animal experiments further confirmed that inflammation and immune regulatory effect of JZOL in the treatment of AB were of vital importance and TRP channels was the key mechanism of action.
