Introduction

Liver disorders represent a significant global health burden, encompassing a wide spectrum of conditions such as viral hepatitis, non-alcoholic fatty liver disease (NAFLD), alcoholic liver disease, and cirrhosis. These conditions not only impair liver function but also pose serious risks of complications, including liver failure and hepatocellular carcinoma. Conventional treatments for liver disorders, while effective to some extent, often come with limitations such as adverse effects and incomplete efficacy, prompting the exploration of alternative therapeutic approaches [1,2]. There has been growing interest in the potential of herbal medicines as complementary or alternative therapies for liver disorders. Herbal medicines, derived from various plant sources and characterized by a complex mixture of bioactive compounds, have been used traditionally in many cultures worldwide [3,4]. These compounds are known to possess diverse pharmacological properties, including hepatoprotective, anti-inflammatory, antioxidant, and immunomodulatory effects, which are particularly relevant to the management of liver diseases. This review aims to examine the pharmacological mechanisms through which herbal medicines exert their effects in treating liver disorders [5]. By conducting a comprehensive review and integrating findings from network pharmacology analyses, this study seeks to elucidate the complex interactions between herbal compounds, target proteins, and biological pathways involved in liver disease pathophysiology [6,7]. Specifically, it will highlight key herbal medicines that have been extensively studied for their hepatoprotective effects, such as Milk Thistle (Silybum marianum), Turmeric (Curcuma longa), Schisandra (Schisandra chinensis), Ginger (Zingiber officinale), and Dandelion (Taraxacum officinale). Furthermore, this review will address current gaps in clinical evidence, challenges in standardization of herbal preparations, safety considerations including potential herb-drug interactions, and regulatory issues surrounding the use of herbal medicines in liver disease management [8]. It will underscore the importance of rigorous scientific research, including well-designed clinical trials, to validate the efficacy, safety, and optimal use of herbal medicines as part of integrative approaches to liver disorders. Liver disorders pose significant health challenges globally, ranging from viral hepatitis to non-alcoholic fatty liver disease (NAFLD) and cirrhosis [9]. The conventional treatment options often come with limitations, such as adverse effects and incomplete efficacy. In recent years, there has been growing interest in the use of herbal medicines as alternative or adjunct therapies for liver disorders due to their perceived safety and potential efficacy [10]. This article aims to explore the pharmacological mechanisms of herbal medicines in treating liver disorders through a comprehensive review and network pharmacology analysis.

Overview of herbal medicines in liver disorders

Herbal medicines have been used for centuries in traditional medicine systems such as Traditional Chinese Medicine (TCM), Ayurveda, and others. These medicines are often derived from plant parts like roots, leaves, fruits, and seeds, and they contain a complex mixture of bioactive compounds. In the context of liver disorders, herbs are believed to exert therapeutic effects through various mechanisms, including anti-inflammatory, antioxidant, hepatoprotective, and immunomodulatory actions.

Commonly studied herbal medicines

Several herbal medicines have been extensively studied for their potential benefits in liver disorders. Examples include

Milk thistle (silybum marianum): Known for its hepatoprotective properties, milk thistle extract contains flavonoids like silymarin, which have antioxidant and anti-inflammatory effects.

Turmeric (curcuma longa): Curcumin, the active compound in turmeric, has shown anti-inflammatory and hepatoprotective effects in preclinical and clinical studies.

Schisandra (schisandra chinensis): Used in TCM, schisandra is believed to support liver function through its antioxidant and anti-inflammatory properties.

Ginger (zingiber officinale): Ginger has been studied for its potential in reducing liver inflammation and fibrosis.

Dandelion (taraxacum officinale): Dandelion extracts have shown hepatoprotective effects in animal studies, attributed to their antioxidant and anti-inflammatory properties.

Pharmacological mechanisms

The pharmacological mechanisms underlying the effects of herbal medicines on liver disorders are diverse and multifaceted. They often involve interactions between multiple bioactive compounds and various molecular targets within hepatocytes and other liver cells. Key mechanisms include:

Antioxidant activity: Herbal medicines like milk thistle and turmeric exert antioxidant effects, reducing oxidative stress and lipid peroxidation in liver cells.

Anti-inflammatory effects: Compounds in herbs such as ginger and schisandra can inhibit inflammatory pathways involved in liver injury and fibrosis.

Hepatoprotective actions: Many herbal medicines enhance liver cell regeneration, promote bile flow, and protect hepatocytes from toxins and metabolic stressors.

Modulation of metabolic pathways: Some herbs influence lipid metabolism, glucose homeostasis, and other metabolic processes that impact liver function.

Network pharmacology analysis

Network pharmacology provides a systematic approach to understanding the complex interactions between herbal compounds and biological pathways involved in liver disorders. It involves:

Network construction: Building networks of interactions between herbal compounds, target proteins, and biological pathways relevant to liver function and disease.

Analysis of network properties: Evaluating network topology, identifying key nodes (compounds or targets), and assessing the potential synergistic effects of herbal combinations.

Prediction of therapeutic effects: Using computational models to predict the efficacy of herbal formulations based on their network interactions and molecular mechanisms.

Clinical evidence and challenges

While preclinical studies and traditional uses provide promising insights into the potential benefits of herbal medicines for liver disorders, clinical evidence remains somewhat limited and heterogeneous. Challenges include

Standardization: Variability in herbal preparations can affect consistency and efficacy.

Safety: Herb-drug interactions and potential adverse effects need careful consideration.

Regulatory issues: Herbal products often lack rigorous regulatory oversight compared to conventional medicines.

Conclusion

Herbal medicines represent a promising avenue for the treatment of liver disorders, offering potential benefits through their diverse pharmacological actions. Through a combination of systematic review and network pharmacology analysis, this article highlights the complexity and potential of herbal medicines in liver disease management. Continued research efforts are essential to validate their efficacy, ensure safety, and integrate them effectively into clinical practice. This comprehensive exploration underscores the importance of understanding the pharmacological mechanisms behind herbal medicines' effects on liver disorders, paving the way for future advancements in therapeutic strategies.
