Chrysanthemum (Chrysanthemum morifolium) has a long history of use in traditional Chinese medicine (TCM), where it is commonly used to “dispel wind and clear heat,” which in TCM terms often correlates with symptoms of colds such as fever, headache, and nasal congestion. Chrysanthemum tea is a popular home remedy in East Asia for managing mild upper respiratory infections, especially those with heat-related symptoms (red eyes, sore throat, slight fever). Its use is primarily supported by this traditional context, rather than by robust scientific evidence.

From a pharmacological perspective, chrysanthemum flowers contain flavonoids, phenolic acids, and volatile oils that do exhibit anti-inflammatory and mild antimicrobial properties in laboratory settings. Some small studies and animal models suggest chrysanthemum extracts may inhibit inflammatory mediators and relieve discomfort, but clinical trials in humans specifically for cold symptoms or decongestion are lacking or of poor quality. Thus, while there is plausible biochemical activity, the evidence is not strong enough to support a scientific recommendation for its use as a decongestant.

In summary, chrysanthemum is traditionally used for cold symptoms in East Asian medicine and may offer mild symptomatic relief, but scientific validation for its efficacy as a decongestant remains limited. Most support for its use is rooted in traditional practice and anecdotal experience.
