How to Use Oil of Oregano on Toenail Fungus

  • Take 1 – 3 Oil of Oregano capsules every day – the brand I used had 45 mg. of Oil of Oregano per capsule.

  • Apply Oil of Oregano directly on the infected toenail – You could apply the oil twice a day, once in the morning and again before going to bed.

  • Effectiveness could depend on the overall strength of oregano oil and the duration of treatment.  

Toe nail fungus thrives in warm, damp conditions.

While using oregano oil to treat fungal infections, you should make efforts to keep your feet and toenails dry and clean.

  • Completely dry your feet and toes after showering.

  • Avoid walking barefoot in public showers and locker rooms.
  • Keep toenails cut short.

  • Don’t use the same nail file and nail clipper used on the infected nails on uninfected nails. You may risk spreading the fungus to other nails.

  • Wear 100% cotton socks that allow your feet to ‘breathe’.

  • Changing to dry clean socks when they become wet or sweaty.

  • Wear comfortable shoes with a wide toe ‘box’ so your toes have some wiggle room. Don’t wear tight fitting shoes that press your toes together as this can help spread the fungus from toe to toe.

  • Drink plenty of water.

  • Try to be patient and consistent with the treatment.

Please consult with your doctor before using any natural health supplements.
