The study gathers information about Chinese dietary herbal medicine and flower-derived medicine, focusing on Juhua, from varied sources such as government reports, classic books of Traditional Chinese medicine, doctoral and master's theses, and various databases. The methodology includes summarizing all flower-originated crude medicines listed in Chinese pharmacopeia and their applications for the first time, retracing the edible history and development of flowers in China, discussing the theory of Chinese dietary herbal medicines, and examining flowers as dietary herbal medicines.

Discussion of the results highlights applications in Traditional Chinese medicine and diet, cultivars, phytochemistry, quality control, and pharmacology of Juhua. A safety evaluation of Juhua, along with an overview of chrysanthemum breeding and biotechnology, are included in the findings. The study determines that many herbal flowers, particularly Juhua, have considerably contributed to the prevention and treatment of various diseases in China.
