Because of the strength of oregano oil, home remedies should dilute oregano oil with one part olive oil, suggests Natural Health Advisory. Anyone using a home cure of oregano oil should be aware of any existing allergies that could cause a reaction, such as those to basil, hyssop, lavender, marjoram, mint and sage. A diluted mixture of oregano oil and olive oil is appropriate when using oregano oil topically for ailments such as athletes foot, or when ingesting oregano oil.
Other home remedies using oregano oil are those fighting E. coli and salmonella, regulating menstrual cycles, preventing negative menopause symptoms, and treating allergies, states the Global Healing Center. Using oregano oil topically can also treat muscle aches and discomfort.
To fight sinus infections, individuals should add a few drops of oregano oil to a pot of boiling water, recommends the Natural Health Advisory. A common home remedy, placing a towel over the head and the head over the pot of water, allows the steam to clear out the sinuses.
