Can Zuguang Powder treat onychomycosis (gray nail)?

Many people are unaware they have onychomycosis (commonly known as “gray nail”) in daily life. However, they may notice discoloration or thickening of the nails while washing their feet or taking a shower. Because they find the appearance of the nails unattractive, they often avoid seeking formal medical treatment at a hospital and instead self-medicate with over-the-counter drugs to alleviate symptoms. So, can “Zu Guang San” (Foot Bright Powder) treat onychomycosis?

Can Zu Guang San Treat Onychomycosis?

The therapeutic effect of Zu Guang San on onychomycosis is not particularly pronounced. Although onychomycosis is a common condition, Zu Guang San remains a frequently used topical remedy—both clinically and traditionally—for this infection. Its ingredients are generally related to antifungal agents. First, it is essential to confirm the diagnosis by consulting a dermatologist. If onychomycosis is confirmed, Zu Guang San may be tried—but only under a physician’s guidance to ensure safe and appropriate use and to prevent skin burns.

If Zu Guang San proves ineffective or yields only minimal improvement, dermatology departments in hospitals often prepare customized antifungal formulations, which may offer superior efficacy and greater convenience. Alternatively, systemic oral antifungal medications can also be used to treat onychomycosis; however, these require prolonged treatment courses and necessitate periodic monitoring of liver function during therapy.

Individuals with onychomycosis should avoid consuming spicy or irritating foods, as these may impede nail recovery. Additionally, wearing well-ventilated footwear and keeping the feet dry are important preventive measures. We hope this information has been helpful!
