Traditional Chinese Medicine (TCM) is increasingly recognized for its multi-target immunomodulatory properties. This review systematically synthesizes the current evidence on the mechanisms by which TCM formulas and active ingredients regulate macrophage polarization to modulate the inflammatory response in CHD.

By inhibiting leukotriene-mediated signaling, montelukast targets a pathway involved in bronchoconstriction, mucus secretion, vascular permeability, eosinophil recruitment, cytokine release, and airway remodeling. Available evidence indicates that montelukast may reduce several markers of allergic inflammation, including fractional exhaled nitric oxide, peripheral and tissue eosinophilia, eosinophil-derived mediators, adhesion molecules, selected cytokines, and markers related to airway remodeling. These effects are most consistently demonstrated in asthma and allergic rhinitis, while evidence in chronic urticaria, atopic dermatitis, and other inflammatory conditions remains limited or exploratory. Montelukast's once-daily oral administration and age-adjusted pediatric formulations make it a practical option in selected children, particularly when inhaled therapy is difficult or adherence is problematic. However, montelukast should not be regarded as a direct substitute for corticosteroid-based anti-inflammatory therapy. Current evidence and guideline positioning support its use mainly as an add-on controller, or an alternative when more efficacious treatment is contraindicated. The benefit-risk balance is further shaped by concerns regarding neuropsychiatric adverse events, especially in children, although evidence remains heterogeneous. Current data show no increased risk of severe, diagnostically coded neuropsychiatric events, yet milder sleep-related and behavioral symptoms are consistently reported, so that caution and active monitoring remain warranted.

While recent reviews have broadly surveyed plant-derived exosome-like nanovesicles (PELNVs) across diverse botanical sources or focused on general isolation technologies and drug delivery applications, a systematic synthesis that specifically centers on medicinal and edible plants and integrates isolation methodology with immunomodulatory functionality remains lacking. This review addresses this gap by concentrating on the unique dual identity of MEPELNVs that combines validated pharmacological heritage from traditional medicine with the safety profile of dietary sources, and examines how their immunomodulatory potential is shaped by upstream preparation techniques. As research has progressed, techniques for isolating and preparing these extracellular vesicles have diversified; however, significant challenges remain in improving purity, optimizing yield, and preserving their immunomodulatory and anti-inflammatory biological functions. This review comprehensively surveys current mainstream isolation and preparation methods, analyzes how each technique impacts vesicle integrity and immune-regulatory activity, and discusses their differential effects on inflammatory mediator release and immune cell functionality. Based on recent preclinical findings, we highlight the potential clinical applications of MEPELNVs in three inflammation-centric areas: first, reprogramming macrophage polarization from pro-inflammatory M1 to anti-inflammatory M2 phenotypes to alleviate chronic inflammation; second, remodeling the tumor immune microenvironment by alleviating PD-L1-mediated immunosuppression; and third, ameliorating metabolic inflammation and promoting immune homeostasis in metabolic diseases. In summary, while MEPELNVs present considerable therapeutic opportunities across anti-inflammatory, anti-tumor, and metabolic disease intervention, their clinical translation is currently hindered by substantial challenges. These include the absence of standardized isolation and quality control protocols, batch-to-batch heterogeneity in vesicle yield and cargo composition, incomplete safety and toxicological profiling, poorly understood cross-kingdom regulatory mechanisms, and underdeveloped regulatory frameworks. This review critically discusses these translational barriers and proposes actionable strategies to overcome them, offering a realistic roadmap from bench to bedside.
