Chrysanthemum has the effects of dispersing wind and clearing heat, calming the liver and improving eyesight, and clearing heat and removing toxins (removing heat and toxins from the body). However, the efficacy of medicines in tea is limited, and the therapeutic effect of single medicine is not good. It is recommended that professional physicians identify the symptoms and formulate a prescription to improve the therapeutic effect with other medicines in a reasonable way. Chrysanthemum is slightly cold in nature, sweet and bitter in taste, and belongs to the lung and liver meridians. Its basic function is to dissipate wind and clear away heat, pacify the liver and clear the eyes, clear heat and detoxify the toxin, and is suitable for the treatment of wind-heat and colds, tinnitus and forgetfulness, headache and vertigo, redness of the eyes and swelling and pain, dimming of the eyes and blurring of the vision, and the treatment of carbuncles and ulcers and poisons. White chrysanthemum is good for calming the liver, clearing liver fire and improving eyesight (clearing liver fire to promote eyesight recovery). Yellow chrysanthemum is good for dispersing wind-heat. The adverse reactions and contraindications of chrysanthemum are not clear. When discomfort occurs, one should seek medical advice and choose medication under the guidance of physician’s diagnosis, rather than self-medication, in order to avoid delaying the condition.
