What Medicinal Benefits Can Be Derived from Yellow Dock?


Nail fungal infections are common, and this infection may happen to anyone. This type of infection may not be serious, but it can be challenging to treat. It is said that about 10 percent of the population has nail fungal infections. The question remains: how do we get them?

A nail fungal infection is medically known as onychomycosis. It is a fungal infection that affects the nail plate and the nail bed, which often appears as a yellowish, black, green, white, or brown discoloration of the nail. The infected nail may appear brittle, thickened, and crumbly. In severe infections, the nail may break into pieces and fall off.

Nail fungus infections typically don’t heal on their own without resorting to a nail fungus treatment. The fungus may spread to other parts of the hands and feet. The infection may range from mild with only cosmetic implications to more severe and cause pain and discomfort.

Toenails are more prone to this infection than fingernails. This is because they take time to grow and they are more exposed to a warm and moist environment inside the shoes.

Causes and Symptoms

Nail fungal infections are often brought about by different kinds of fungi, yeasts, and molds. Fingernail fungal infections are often caused by yeast fungi, particularly Candida. Fungal nail infections are common among older male adults who suffer from chronic conditions like diabetes and circulation issues. Those who frequent public places that are often damp like swimming pools and shower rooms are more prone to it. It’s the same thing with those who frequent nail salons.


A nail fungus treatment depends on the microorganism that caused the infection as well as its level of severity. For severe cases, the doctor may prescribe oral antifungals like fluconazole, terbinafine, and griseofulvin. An alternative nail fungal treatment may also be advised by the doctor in the form of nail lacquer, cream, or ointment. Sometimes the doctor may recommend a combination of the two.
