Abstract:
The occurrence and development of metabolic dysfunction-associated steatotic liver disease (MASLD) are closely related to intestinal flora imbalance, intestinal barrier damage, and gut-liver axis dysfunction. Due to their multi-target regulatory effects and advantages in intestinal microecological intervention, Chinese herbal monomers have shown promising application prospects in the prevention and treatment of MASLD. However, basic research on their toxicity still lags behind, and issues related to safety and clinical translation urgently need attention. This article systematically reviews the research progress on how flavonoids, triterpenoids, alkaloids, and polysaccharides improve hepatic steatosis, inflammatory responses, and metabolic disorders from a toxicological perspective by reshaping the intestinal microbiota, repairing the intestinal mucosal barrier, regulating short-chain fatty acid and bile acid metabolism, and synergistically acting on signaling pathways such as TLR4/NF-kB, FXR, TGR5, SIRT1, and the NLRP3 inflammasome. Furthermore, by combining methods such as 16S rRNA sequencing, metagenomics, metabolomics, and multi-omics integration, the article analyzes their application value and limitations in toxicological mechanism research, and discusses the translational bottlenecks faced by Chinese herbal monomers in pharmacokinetics, bioavailability, quality standardization, targeted delivery, and toxicological safety. Existing evidence indicates that Chinese herbal monomers have a three-in-one intervention advantage of microecological remodeling-metabolic regulation-inflammation inhibition, but their long-term medication safety, toxic target organs, dose-effect/toxicity relationships, and potential drug interactions still need further clarification. This article aims to provide a systematic reference for the safety evaluation and clinical translational research of Chinese herbal monomers in the prevention and treatment of MASLD.
Insights
Chinese herbal monomers show promise for treating metabolic dysfunction-associated steatotic liver disease (MASLD) by improving gut health and inflammation. Further research is needed to clarify their long-term safety and clinical application for MASLD.
Area of Science:
- Pharmacology and Toxicology
- Gastroenterology
- Integrative Medicine
Background:
- Metabolic dysfunction-associated steatotic liver disease (MASLD) is linked to gut microbiota imbalance and gut-liver axis dysfunction.
- Chinese herbal monomers offer multi-target benefits for MASLD, particularly in microecological intervention.
- Toxicity and safety research for these monomers lag, hindering clinical translation.
Purpose of the Study:
- To systematically review the toxicological perspective of Chinese herbal monomers in treating MASLD.
- To analyze their mechanisms including gut microbiota modulation, barrier repair, and metabolic regulation.
- To discuss limitations and translational bottlenecks for clinical application.
Main Methods:
- Review of research on flavonoids, triterpenoids, alkaloids, and polysaccharides.
- Analysis of toxicological data and mechanisms of action.
- Integration of multi-omics approaches (16S rRNA, metagenomics, metabolomics).
Main Results:
- Herbal monomers reshape gut microbiota, repair intestinal barrier, and regulate SCFA/bile acid metabolism.
- They modulate key signaling pathways (TLR4/NF-kB, FXR, TGR5, SIRT1, NLRP3 inflammasome).
- A three-in-one advantage of microecological remodeling, metabolic regulation, and inflammation inhibition is evident.
Conclusions:
- Chinese herbal monomers present a promising therapeutic strategy for MASLD.
- Further research is crucial to address long-term safety, dose-effect relationships, and drug interactions.
- Clarifying toxicological profiles is essential for successful clinical translation.
