As an antifungal treatment for nails, dilute oregano oil in a carrier oil of your choice to a 1:1 ratio. Apply 1 drop to the affected area 1-2 times a day until the fungal infection clears.
As part of an antibacterial room spray, mix together the following essential oils in a 500ml spray bottle filled with water and a teaspoon of dishwashing liquid:
5 drops oregano
3 drops thyme
10 drops frankincense
10 drops tea tree
15 drops lavender
10 drops marjoram
Be careful not to accidentally spray at eye-level. Vacate the room and allow the mist to disperse for 5 minutes, just to be safe.
Do not use oregano oil daily for an extended period. Aim for short, 7-day applications at a time for acute conditions. Long-term use of oregano oil may lead to complications or changes in liver metabolism, so don’t take chances with it.
Oregano oil is high in a chemical compound called carvacrol as well as thymol, which are the key reasons behind its strong antibacterial, antifungal and antiviral actions. It also affects platelet aggregation, and so is not recommended for use by people with blood clotting disorders, or patients who are taking anticoagulant drugs such as aspirin or Warfarin, or before surgery.
Do not use with infants, babies, pregnant and lactating women.
Will cause skin irritation in high doses, and will also irritate mucous linings (i.e. the inside of your mouth, throat, eyes and nose). Do not use in steam inhalation unless blended together to a maximum of a 10% concentration with other less potent essential oils, and only 1 drop of this blend is used at a time.
