Future studies should focus on comprehensive clinical trials, bioavailability assessments, and the development of new technologies to enhance the efficacy and consumer acceptance of MFH functional foods (Marotta et al., 2012; Hou and Jiang, 2013; Granato et al., 2017; Brown et al., 2018; Birch and Bonwick, 2019). 6 Safety and Standardization of Food-Medicine Homology Functional Foods 6.1 Safety evaluation of food-medicine homology products The safety evaluation of food-medicine homology (FMH) products is a critical step in ensuring that these functional foods are safe for consumer use. Given the dual nature of FMH products, which combine both nutritional and medicinal properties, rigorous safety assessments are necessary. These evaluations typically involve both preclinical and clinical testing phases. Preclinical testing often includes in vitro and in vivo studies to assess the potential toxicity, bioavailability, and pharmacokinetics of the active ingredients (Jones and Jew, 2007; Granato et al., 2020). Clinical trials are then conducted to confirm the safety and efficacy of these products in human subjects. Moreover, the safety of FMH products is also evaluated through the lens of traditional Chinese medicine (TCM) and modern pharmacology. TCM provides a historical context for the use of these products, while modern pharmacology offers a more detailed understanding of their mechanisms of action and potential side effects(Hou and Jiang, 2013; Yuanyuan et al., 2023). This dual approach ensures a comprehensive safety profile for FMH products, addressing both traditional and contemporary safety concerns. 6.2 Standardized production and quality control Standardized production and quality control are essential for the consistent efficacy and safety of FMH functional foods. The production process must adhere to stringent guidelines to ensure that the final product meets the required standards. This involves the use of high-quality raw materials, standardized extraction processes, and rigorous quality control measures (Jones and Jew, 2007; Granato et al., 2020). Quality control is particularly important in the context of FMH products, as the active ingredients can vary significantly depending on the source and processing methods. Advanced analytical techniques, such as high-performance liquid chromatography (HPLC) and mass spectrometry, are often employed to ensure the consistency and purity of the active ingredients (Figure 1) (Hou and Jiang, 2013; Alongi and Anese, 2021). Additionally, the development of a comprehensive database for FMH varieties can aid in the standardization process by providing a reference for the identification and quantification of active ingredients (Hou and Jiang, 2013). 6.3 Regulatory compliance and market entry Regulatory compliance is a significant hurdle for the market entry of FMH functional foods. Different countries have varying regulations regarding the approval and labeling of functional foods, which can complicate the market entry process. For instance, the European Union, the United States, and Japan each have distinct regulatory frameworks for functional foods, which include specific requirements for health claims and safety assessments (Kwak and Jukes, 2001; Bech-Larsen and Scholderer, 2007; Díaz et al., 2020). In the European Union, the regulatory framework is particularly stringent, requiring substantial evidence to support health claims. This often involves comprehensive clinical trials and detailed documentation of the product's safety and efficacy (Bech-Larsen and Scholderer, 2007; Birch and Bonwick, 2019). In contrast, the regulatory frameworks in the United States and Japan are somewhat more flexible but still require rigorous safety and efficacy data (Kwak and Jukes, 2001; Díaz et al., 2020). To navigate these regulatory landscapes, FMH product developers must engage in thorough documentation and compliance efforts. This includes compiling detailed dossiers that provide evidence of the product's safety, efficacy, and quality. Additionally, effective communication strategies are essential to educate both regulators and consumers about the benefits and safety of FMH products (Alongi and Anese, 2021; Baker et al., 2021). The
