Both chrysanthemum and chrysanthemum come from chrysanthemum, only the flowering period is different at the time of harvesting. Chrysanthemum is the dried flower buds of chrysanthemum in the family of Asteraceae, and chrysanthemum is the head-like inflorescence of chrysanthemum in the family of Asteraceae. However, the efficacy is the same, both have the efficacy of dispersing wind and clearing heat, calming the liver and brightening the eyes, and clearing heat and removing toxins (removing heat and toxins from the body). Chrysanthemum is cold in nature and can clear liver heat and calm liver yang. It is often used for headache and dizziness, tinnitus and forgetfulness caused by yin deficiency and hyperactivity of yang (deficiency of yin fluid and hyperactivity of yang).

Chrysanthemum is pungent and bitter, slightly cold and heat-clearing, and mainly enters the liver meridian, which can not only clear wind-heat, but also clear liver-heat, and also benefit yin, with the effect of brightening the eyes. Its functions are similar to those of Mulberry leaf, but it is more powerful in clearing liver heat and improving eyesight (clearing liver fire to promote the recovery of vision). Commonly used in wind-heat attack or liver fire due to inflammation of the eye red swelling and pain, shyness and tears (eyes afraid of light, often tears) and the liver and kidney essence and blood deficiency, blurred vision, and so on. Chrysanthemum is bitter and slightly cold in flavor, and can clear heat and detoxify. It is suitable for the treatment of feverish sores and ulcers, both internally and externally.
