Chrysanthemum has the efficacy of dispersing wind-heat, clearing heat and removing toxins (removing heat and toxins from the body), clearing the liver and brightening the eyes (removing liver fire to promote the recovery of vision), and it is mainly used for treating wind-heat and colds, sores, carbuncles and swollen toxins and the internal movement of the liver wind, caused by high fever, headache, vertigo, blurred vision, and so on. It is not to be used by those with Yang deficiency or those with headache and cold (fear of cold). Cassia seeds have the effect of clearing heat and calming the liver, brightening the eyes, moistening the intestines and laxatives, used for eye redness and astringent pain, shyness and tearfulness (eyes afraid of light, often tears), headache and dizziness, dark and unclear eyes, constipation. Diarrhea and low blood pressure should be used with caution. It can be seen, chrysanthemum, cassia seeds combined with heat, eyesight and laxative effect, drinking water with limited active ingredients, generally do not reach the therapeutic effect. However, chrysanthemum and cassia seeds are cold in nature, easy to hurt the spleen and stomach, spleen and stomach cold (spleen and stomach weak cold) people should be careful to drink, so as to avoid diarrhea, abdominal pain and other gastrointestinal discomfort.
