Propolis can effectively support the development of nail fungus, as propolis is one of the natural anti-fungal agents. Nail fungus (nail mycosis, onychomycosis) is an infectious disease that affects the fingernails and / or toenails and is caused by filamentous fungi (dermatophytes, molds) or sprouts (yeasts). The fungal spores cause a white to yellow-brown discoloration of the nail, it becomes thicker and often also brittle to crumbly. To treat nail fungus, apply the propolis tincture directly to the affected nail and let it dry. The propolis tincture then sticks to the nail and can develop its effect. Alternatively, foot baths with propolis can also be helpful. Put 30 drops of propolis tincture in a water bath. The exposure time should not be less than 20 minutes.
