Objectives: This review aims to systematically summarize turmeric’s botanical traits, traditional medicinal applications, phytochemical components and their biological activities, and to integrate botanical, phytochemical, molecular and clinical perspectives to provide a comprehensive theoretical foundation and practical guidance for the future scientific research and clinical applications of turmeric as a functional food. Methods: A systematic overview and comprehensive analysis were conducted on the existing research about turmeric, covering its botanical characteristics, traditional medicinal application value, the biological mechanisms of major bioactive compounds (especially curcumin), pharmacokinetic properties, and the latest progress in relevant clinical trials. Results: Turmeric has important historical and cultural significance in traditional medicine, and its major bioactive compound curcumin is the core of its therapeutic potential, which can modulate antioxidant, anti-inflammatory, and antitumor signaling pathways. Recent studies have found that curcumin exerts significant biological effects by regulating noncoding RNAs (ncRNAs) and epigenetic modifications, showing a promising role in cancer chemoprevention. Meanwhile, curcumin has specific pharmacokinetic properties, and current clinical trials on turmeric and curcumin have made certain progress, yet challenges such as low bioavailability and limited therapeutic efficacy still exist. Conclusions: Turmeric, as a widely recognized functional food with rich phytochemicals and diverse biological activities, has great potential in scientific research and clinical application, especially in cancer chemoprevention. Solving the key challenges such as curcumin’s bioavailability and therapeutic efficacy is the core direction for the future development and utilization of turmeric, and the multi-dimensional research perspective can provide more comprehensive support for its practical application as a functional food.

Gouty arthritis (GA) is a debilitating autoinflammatory disorder precipitated by the deposition of monosodium urate (MSU) crystals, leading to intense, recurrent joint inflammation and systemic metabolic dysregulation. While hyperuricemia is a prerequisite, the transition to clinical gout involves complex intercellular signaling cascades that are not fully understood. Emerging evidence has identified exosomes,— nanoscale extracellular vesicles, —as critical mediators in this pathological process. Exosomes function as intercellular carriers, transporting a diverse cargo of bioactive molecules, including proteins, lipids, and nucleic acids (e.g., microRNAs), which profoundly influence immune cell activation, inflammasome regulation, and metabolic pathways. This review provides a critical analysis of the dual role of exosomes in both propagating and potentially resolving inflammation in GA. We delve into the intricate mechanisms of exosome-mediated pathogenesis, including the modulation of purine metabolism, lysosomal function, and complement–inflammasome crosstalk. Furthermore, we explore the burgeoning field of exosome-based therapeutics, critically evaluating strategies such as engineered exosomes for targeted drug delivery, mesenchymal stem cell (MSC)-derived exosomes for immunomodulation, and the development of exosomal biomarkers for diagnostics. Additionally, we examine how chemical drugs and herbal compounds may exert therapeutic effects by modulating exosome pathways, offering new insights into integrative treatment approaches. By synthesizing recent findings from proteomic, transcriptomic, and functional studies, we aim to unravel the complexities of exosome signaling in GA and to propose innovative therapeutic avenues that target these pathways to improve patient outcomes.
