Chinese herbal medicine Xiangsu Hewei Granules in treating non-erosive gastroesophageal reflux disease with liver stomach stagnation heat syndrome: A multicentre, randomized, double-blind, placebo-controlled trial.
An eight-week placebo-controlled trial reported better heartburn and acid-regurgitation responses with Xiangsu Hewei Granules in a narrowly selected group of adults. The study does not answer whether the preparation works better than standard proton pump inhibitor treatment.
What did the trial test?
Researchers studied 480 adults aged 18 to 65 with non-erosive gastroesophageal reflux disease and a specified traditional Chinese medicine syndrome. Participants had a GerdQ score of at least 8 and tested negative for H. pylori. The trial used random assignment, blinding and a placebo comparison across multiple centres.
How was the treatment compared?
Participants were assigned in a three-to-one ratio to the herbal preparation or placebo. They took the assigned treatment three times a day for eight weeks. The main outcomes concerned response in heartburn and acid-regurgitation scores at week eight, rather than a comparison with another active reflux treatment.
What results were reported?
The analysis included 479 participants: 360 in the treatment group and 119 in the placebo group. Reported heartburn-response rates were 76.39% and 21.01%, respectively. Acid-regurgitation response was reported in 79.72% of the treatment group and 23.53% of the placebo group. These percentages describe the study's defined symptom response, not cure rates.
What remains uncertain?
The authors caution that these results may not apply to the broader reflux population. Their participants were selected using several clinical criteria, including negative H. pylori testing and low anxiety/depression scores. Comparative effectiveness against proton pump inhibitors remains untested by this placebo comparison. The findings should not be used to replace prescribed treatment without a clinician's assessment.
How to read this explanation
This explanation is based on the paper's abstract, not an independent review of the full methods, participant-level data or safety records. It preserves the distinction between what the researchers reported and what the study can establish. Read the underlying paper before making a clinical or research decision.
