Onychomycosis is stubborn and difficult to treat. After trying a variety of treatment methods, it is what patients expect to find the one that suits them best. The traditional treatment of onychomycosis is nothing more than surgical removal of onychomycosis, oral antifungal drugs and external application. Surgical nail removal is not ideal; Take only griseofulvin, fluconazole, itraconazole and other antifungal drugs. , has a certain effect, but because this kind of drugs must reach the deck where fungi live to play an antibacterial role, and the solubility in water is low and slow, and the absorption and metabolism are fast, the dosage is large and the medication time is long, which is easy to cause normal flora imbalance. Oral drugs have great side effects on liver and kidney, and it is easy to relapse after stopping taking drugs, which is not an ideal choice.
