Chrysanthemum and Lycium are used together to nourish the liver and kidneys and brighten the eyes. They can be used to treat dry eyes, blurred vision, and tears in the wind caused by deficiencies in the liver and kidneys. These two drugs are mainly used for the treatment of dry eyes caused by deficiency of fluid or essence and blood in the elderly, such as cataracts and dry eyes in the elderly, or the treatment of dry eyes in white-collar workers and drivers who use their eyes excessively. However, because the chrysanthemum is cold in nature, and the wolfberry is nourishing and greasy in nature, for people with weak spleen and stomach or cold spleen and stomach, taking it may cause certain symptoms of indigestion, so these people should be used with caution.
