Abstract
AIM: To evaluate the anti-Helicobacter pylori (H. pylori) activity of 50 traditional Chinese herbal medicines in order to provide the primary evidence for their use in clinical practice.
METHODS: A susceptibility test of water extract from 50 selected traditional Chinese herbal medicines for in vitro H. pylori Sydney strain 1 was performed with broth dilution method. Anti-H. pylori activity of the selected Chinese herbal medicines was evaluated according to their minimum inhibitory concentration (MIC).
RESULTS: The water extract from Rhizoma Coptidis, Radix Scutellariae and Radix isatidis could significantly inhibit the H. pylori activity with their MIC less than 7.8 mg/mL, suggesting that traditional Chinese herbal medicines have anti-inflammatory and antibacterial effects and can thus be used in treatment of H. pylori infection.
CONCLUSION: Rhizoma Coptidis, Radix Scutellariae and Radix isatidis are the potential sources for the synthesis of new drugs against H. pylori.
