Studies have demonstrated its renoprotective effects, where it significantly reduced serum creatinine levels, proteinuria, and glomerulosclerosis in progressive renal failure. This effect is likely mediated by suppressing angiotensin II and regulating TGF-beta1 and type IV collagen expression. Additionally, Rehmannia glutinosa has shown neuroprotective benefits, improving memory impairments and cognitive functions in models of neurodegenerative diseases by enhancing cholinergic activity and reducing inflammation. The herb also exhibits substantial anti-inflammatory and immune-modulating properties. In atopic dermatitis models, Rehmannia glutinosa extract has been effective in reducing dermatitis scores, ear thickness, and serum histamine levels, showcasing its anti-inflammatory capabilities. Furthermore, it enhances immune responses by activating natural killer cells and dendritic cells, contributing to its broad immunomodulatory effects. Moreover, Rehmannia glutinosa has shown potential in promoting bone health. It prevents bone loss and enhances bone formation in models of osteoporosis and diabetes-induced bone deterioration through the regulation of the IGF-1/PI3K/mTOR pathways. Metabolic benefits of Rehmannia glutinosa include its role in reducing waist circumference in obese individuals, potentially by modulating gut microbiota, and its efficacy in managing blood glucose levels in diabetic models. The integration of traditional Chinese medicine (TCM) and modern medical practices offers a comprehensive approach to healthcare, leveraging the strengths of both systems. Combining Rehmannia glutinosa with conventional treatments could enhance therapeutic outcomes, especially in chronic conditions such as renal failure, neurodegenerative diseases, and metabolic disorders. TCM's holistic approach can complement modern medicine by addressing the root causes of diseases and promoting overall well-being. Utilizing herbal therapies like Rehmannia glutinosa may reduce the reliance on synthetic drugs, potentially lowering the incidence of adverse effects and improving patient compliance. Continued research into the pharmacological mechanisms and active compounds of Rehmannia glutinosa can lead to the development of novel therapies that bridge traditional and modern practices. Integrating Rehmannia glutinosa into modern therapeutic regimens presents a promising avenue for enhancing patient care. Future research should focus on conducting rigorous clinical trials to validate the efficacy and safety of Rehmannia glutinosa in various medical conditions. Mechanistic studies exploring the molecular mechanisms underlying its therapeutic effects are crucial for identifying potential targets for drug development. Developing standardized extracts and formulations will ensure consistent quality and potency in clinical applications. Additionally, increasing awareness among healthcare providers and patients about the benefits of integrating TCM with modern medicine can foster acceptance and utilization. By embracing the strengths of both traditional and contemporary medicine, we can provide more effective, holistic, and patient-centered healthcare solutions.
