Chrysanthemum tea has a certain effect on clearing the lungs, because chrysanthemum itself is cold in nature and is unique in clearing heat, and at the same time enters the lung and liver meridians. For example, if liver heat is caused by emotional anxiety, busy work and poor mood, and liver fire offends the lungs, it is more appropriate to drink chrysanthemum tea at this time. Chrysanthemum and mulberry leaves are good partners in the Chinese herbal formula to clear the lung, as mulberry leaves itself has the effect of cooling and clearing the lung, while chrysanthemum clears the lung and at the same time has a stronger effect of clearing heat and detoxification. Therefore, the two drugs are more effective in clearing lung heat when combined. The representative formula of Chinese medicine is Sang Ju Drink, which contains mulberry leaves and chrysanthemum flowers, with the appropriate addition of orris, almonds and rehmannia, which can achieve a pungent and cooling pacifier to treat lung heat, and has a better effect in treating early wind-heat colds, and its taste is not bitter, although chrysanthemum flowers taste bitter, but other drugs are not bitter, and there is a certain difference with Yin Qiao San, which is more bitter.
