Chrysanthemum (Chrysanthemum morifolium, 菊花, "ju hua") has a long history in Traditional Chinese Medicine (TCM) as a remedy for various eye conditions, particularly for red, swollen, or itchy eyes often associated with "wind-heat" or liver fire. In TCM, chrysanthemum is believed to have cooling and anti-inflammatory properties, which help clear heat and detoxify the body, thus alleviating eye discomfort. Classic TCM texts, such as the "Shennong Bencao Jing" and other materia medica, recommend chrysanthemum in decoctions or teas, sometimes combined with other herbs like goji berry (Lycium barbarum), specifically to benefit vision and relieve eye irritation.

From a scientific standpoint, limited laboratory studies suggest that chrysanthemum contains flavonoids, phenolic acids, and other antioxidants, which may have anti-inflammatory effects. Some in vitro and animal studies indicate a potential for reducing inflammation and oxidative stress, which could theoretically help with eye irritation. However, robust human clinical trials are lacking, and there is no direct scientific evidence confirming its efficacy specifically for red or itchy eyes in humans. Thus, the use of chrysanthemum for this purpose is primarily justified by traditional practice, with modest support from preliminary pharmacological data, but not by strong modern clinical evidence.
