The nutritional value of brewing with chrysanthemum lies in the fact that some of the nutrients, such as flavonoids, can be dissolved in water and enter the human body along with the drinking water to replenish the corresponding nutrients. The nutritional value of chrysanthemum is that it is rich in flavonoids, volatile oils, amino acids, carotenoids, vitamins, and trace elements such as magnesium, iron, and calcium, which can effectively replenish the nutrients needed by the human body. Fetal chrysanthemum is one of the finest types of chrysanthemum, which is precious due to its scarce production. However, due to the limited solubility of nutrients in water when brewed with fetal chrysanthemum, fetal chrysanthemum does not have any therapeutic efficacy and function, and can only provide a certain amount of nutrients for the organism. Note: Because the water is rich in flavonoids and other substances that are easily oxidized by oxygen in the air, it should be consumed as soon as possible after brewing.
