How to fight nail fungus in an efficient way

By Vitia

Nail fungus, also known as onychomycosis, is a very common problem that affects both men and women. In addition to causing changes in the color and thickness of the nails, they can cause bad odor, brittleness and, in some cases, pain. Many people resort to expensive treatments without obtaining good results, when in reality there are natural alternatives that can help combat this problem in a simple and effective way.

In this article, I share with you a powerful homemade formula, made with easy-to-find ingredients, that helps to eliminate fungi progressively when applied consistently.

You can also follow the preparation and how to use it, in the following video from the
Loucos das Plantas channel:

Why do nail fungus appear?

Fungi develop mainly in moist and hot environments. Among the most frequent causes are:

  • Prolonged use of closed-toe shoes
  • Excessive sweating
  • Lack of proper drying after bathing
  • Use of unprotected public swimming pools
  • Low defenses
  • Small wounds on the nail

Once installed, fungi can spread easily if not treated in time.

Ingredients for anti-fungal formula

This recipe combines ingredients with antifungal, antibacterial and cleansing properties:

  • A little toothpaste
  • A drizzle of excellent quality oil (preferably olive oil)
  • 1 teaspoon baking soda
  • 1 sprig of rosemary, using only its leaves

How to prepare homemade antifungal pasta

  1. Place some toothpaste in a bowl.
  2. Add a teaspoon of baking soda.
  3. Add a drizzle of olive oil.
  4. Finely chop the rosemary leaves and add them to the mixture.
  5. Mix everything until it forms a homogeneous paste.

This preparation will result in a powerful paste that helps fight nail fungus.

Correct application mode

  1. Wash the affected area thoroughly with warm water and mild soap.
  2. Dry the nail very well, especially between the edges.
  3. Apply the paste directly to the fungal area.
  4. Leave on for 20 minutes.
  5. Remove with warm water and dry again.

This treatment can be applied once a day, preferably in the evening.

Why this formula is effective

  • Baking soda helps neutralize the acidic environment that fungi need to thrive.
  • Toothpaste provides antiseptic and cleaning agents.
  • Olive oil moisturizes and helps the ingredients penetrate better.
  • Rosemary possesses natural antifungal and antibacterial properties.

The combination of these ingredients creates a hostile environment for the fungus, favoring its progressive elimination.

Additional Tips to Speed Up Results

  • Keep your nails always short and clean.
  • Avoid prolonged use of nail polishes for the duration of the treatment.
  • Wear ventilated shoes and change your socks daily.
  • Don’t share towels, files, or nail clippers.
  • Carefully dry your feet after each bath.

Consistency: the key to success

Like any natural treatment, the results are not immediate, but with constant daily use improvements can be observed in a few weeks. The healthy nail will grow slowly as the fungus weakens.
