Abstract

Aim: The purpose of this study was to explore the effects of goreisan (GRS) on rats through the analysis of 1H-NMR of urine samples, to assess the variations in metabolites affected by GRS, and to gain a new metabolomic understanding of the effects of Kampo medicine. Methods: Male Wistar rats were randomly divided into two groups: a control group that was fed a standard diet, and a GRS group that was fed a 1% GRS diet. The study was conducted over a four-week period. At the end of the experiment, urine samples were analyzed using 1H-NMR spectroscopy to evaluate the metabolic changes induced by GRS administration. Additionally, various blood parameters were also analyzed. Results: Administration of GRS resulted in an elevation of lactate, acetate, and other metabolites, such as trimethylamine-N-oxide and hippurate, in urine. Additionally, there was a significant decrease in the blood urea nitrogen (BUN) level in the blood of the GRS-treated group. Conclusion: This study has highlighted the substantial changes in lactate, acetate, and other urine metabolites caused by GRS. The findings demonstrate the effectiveness of 1H-NMR spectroscopy in assessing metabolic alterations in response to the therapeutic application of a Kampo formula. This research contributes to the knowledge of mechanisms of action from a metabolomic point of view and offers fresh insights into the effects of complex Kampo formulas such as GRS, using 1H-NMR spectroscopic techniques.
