Gray nail is a fungal infection that causes infection of the nail plate and the underlying nail tissue. The efficacy of Fenugreek in treating gray nails is not exact. However, if the nail is not well controlled, the patient may suffer from total destruction of the nail and even severe pain. And grey nails are currently among the better treatment drugs in the clinic, like ciclopirox, amorolfine, tincture of iodine, and oral antifungal drugs, like itraconazole, terbinafine, and fluconazole, so patients should still go to the regular hospital dermatology department to treat grey nails.
