Chinese herbal medicine treatment alone is usually not able to kill H. pylori, but when combined with gastric IV treatment, Chinese herbal medicine treatment can play a supplementary therapeutic role, i.e., Chinese medicine is based on adjusting human constitution and treating evidence, which can improve human immunity, so combined with gastric IV can improve the eradication rate of H. pylori. In addition, the standard gastric quadruple therapy protocol prescribed by the national guidelines may cause indigestion symptoms such as abdominal pain, diarrhea and poor appetite because of the use of two antibiotics, and the simultaneous use of TCM treatment can improve the above symptoms and achieve a good therapeutic effect. At present, the rate of H. pylori infection in China is about 40%-50%, while the eradication rate of H. pylori is only about 80%-90%. Therefore, for patients with H. pylori infection who failed in the first-line treatment, they can try to add Chinese herbal medicine treatment when using the second-line treatment, which can increase the eradication rate and achieve the purpose of improving the treatment.
