Medicine and food homology culture has a long history in China. With the continuous improvement of people's living standards, there has been a growing investment in health care, leading to significant development in the health industry. Medicinal and food homologous substances, receiving increasing attention, have become the breakthrough and mainstay of the health industry, with broad prospects for related industries. However, the medicinal and edible industry currently faces numerous challenges, especially regarding the research on quality standards for medicinal and food homologous substances, where the study of food attributes is still in its infancy. Therefore, this article elaborated on the current research status of quality standards for medicinal and food homologous substances, clarified the confusion surrounding the concept of medicinal and food homologous substances, and analyzed the weaknesses in the research on food attributes in the quality standards of medicinal and food homologous substances, as well as the lack of unified safety indicators. Based on the dual attributes of medicinal and food homologous substances, it is suggested that research on quality stan-dards should encompass authenticity, safety, nutrition, and efficacy. Under the premise of ensuring authenticity, the safety of exogenous toxic substances should be evaluated in combination with their dual attributes. In the formulation of standards, the nutritional aspect of food properties should be strengthened, and different indicators should be selected for comprehensive quality control based on the sources and properties of medicinal and food homologous substances. By employing multiple techniques for holistic control from various perspectives, a set of systematic quality standards applicable to medicinal and food homologous substances can be established. This study is expected to provide references for the quality control, safe use, and regulation of medicinal and food homologous substances, thereby promoting the healthy development of the entire industry.
