Chinese mugwort (Artemisia argyi) has been used in traditional Chinese medicine (TCM) for a variety of purposes, primarily for its warming and blood-invigorating properties. Historical texts and herbal compendia mention its use in the treatment of skin conditions, gynecological issues, and as a general tonic. In the context of eye health, mugwort is sometimes included in herbal formulas intended to alleviate symptoms such as redness or itching, often attributed to "wind-heat" or "liver fire" in TCM theory. The traditional rationale is based on mugwort's ability to dispel dampness and clear heat, which are believed to contribute to ocular discomfort in TCM diagnostics. However, there is little direct mention in classical sources of mugwort being a primary or standalone remedy for red or itchy eyes; it is more commonly used as a supporting herb in complex formulas.

From a scientific standpoint, there is minimal research specifically investigating the efficacy of Artemisia argyi for eye conditions such as redness or itching. Most modern pharmacological studies focus on its anti-inflammatory, antimicrobial, and antioxidant properties in broader contexts. Therefore, the support for mugwort’s use in treating eye irritation is primarily traditional, with weak direct evidence in both traditional and scientific literature for this specific indication.
