Traditional Chinese medicine (TCM) is an ancient healing system that has been practiced for thousands of years in China and other East Asian countries. According to the TCM theory, medicine and food share the same origin and may have the same functions in the prevention and treatment of various health conditions. This is how the concept of medicine and food homology is developed and popularized. In China, an official list of medicine and food homology substances is promulgated by the China National Health Commission (formerly Ministry of Health) (NHC, 2002; NHC, 2020a; NHC, 2020b). All these substances are included in the Chinese Pharmacopoeia and safe to be used as food.
