Centipeda minima, commonly known as "small sneezeweed," has a long history of use in traditional Chinese medicine (TCM) for supporting ear health, particularly in treating conditions like chronic rhinitis, sinusitis, and ear-related ailments such as otitis media and hearing loss. In TCM, it is often included in herbal formulations intended for nasal and ear complaints, with the belief that its anti-inflammatory and antimicrobial properties help clear obstructions and reduce swelling in the ear, nose, and throat region.

There is limited scientific research specifically validating the efficacy of Centipeda minima for ear conditions. Some laboratory studies have reported anti-inflammatory, antimicrobial, and antioxidant activities of extracts from this plant, which theoretically could support its traditional uses for infections and inflammation in the ear. However, robust clinical trials in humans are lacking, and most of the support for its use in the ear body system remains anecdotal or based on traditional practice rather than solid scientific evidence.

In summary, Centipeda minima's reputation as a support for the ear system is primarily rooted in traditional medicine rather than well-established scientific validation.
