Introduction
The claim that Fengyoujing (wind oil) can cure onychomycosis (gray nail) in 7 days is unscientific and incorrect. One should maintain personal hygiene, trim nails regularly, and keep nails clean and dry, avoiding prolonged immersion in water or staying in damp environments. At the same time, a balanced diet with increased intake of fresh vegetables, fruits, and high-quality protein can help enhance the body's immunity to resist fungal infections.
Generally speaking, the claim that Feng You Jing (a topical analgesic) can treat onychomycosis (fungal nail infection) in 7 days is unscientific and incorrect. The detailed explanation is as follows:
Onychomycosis is a condition caused by fungi such as dermatophytes and yeasts invading the nail plate or underlying tissue. The main ingredients of Feng You Jing include menthol, camphor, eucalyptus oil, eugenol, and others, which primarily provide cooling, pain-relieving, anti-pruritic, and wind-dispelling effects. These components do not have clearly established antifungal properties. Although some argue that ingredients like camphor in Feng You Jing may have certain antibacterial and anti-inflammatory effects and might contain salicylic acid, an agent with potential antifungal activity, these components have limited penetration and fungicidal effectiveness against fungi deeply embedded in the nails. Therefore, the efficacy of Feng You Jing in treating onychomycosis is uncertain and cannot significantly cure the condition in a short period.
Maintaining personal hygiene, regularly trimming nails, and keeping nails clean and dry are important in daily life. Avoid prolonged immersion in water or staying in damp environments. Additionally, maintaining a balanced diet rich in fresh vegetables, fruits, and high-quality protein can help enhance immune function and resist fungal infections.
