Green under toenail can be a sign of Green Nail Syndrome (GNS), which is caused by an infection with Pseudomonas aeruginosa bacteria. The green-black discoloration of the nail is due to pyocyanin, an antibiotic pigment produced by the Gram-negative P. aeruginosa. The color of the nail may vary from blue-green, to green-brown, or green-yellow. The infection can occur in two places: between the nail plate and the nail bed, or between the acrylics and the nail plate.
Positive:
- Tobramycin eye drops have been reported to successfully treat GNS.
Negative:
- GNS can be a sign of a more serious condition, such as melanoma, and a biopsy should be performed if there is any concern.
- Fungal infections are a common complication of acrylic nails, and they can cause yellow, green, black, or white discoloration of the nail.
Ingredients or materials:
- Pyocyanin, an antibiotic pigment produced by the Gram-negative P. aeruginosa, is responsible for the green-black discoloration of the nail in GNS.
- Vinegar, Vicks VapoRub, and tea tree oil are some of the home remedies that can be used to treat fungal nail infections.
