10 Best Herbal Essential Oils For Oral Thrush

Herbal essential oils, such as tea tree oil, oregano oil, and clove oil, have been traditionally used for their antimicrobial properties and may offer natural relief for oral thrush, a fungal infection caused by Candida.

These oils contain compounds like terpenes and phenols that can inhibit the growth of Candida albicans, the primary cause of the infection. When properly diluted, they can be applied directly to the affected areas in the mouth, helping to reduce inflammation and discomfort. However, it is important to use these oils cautiously, as they can be irritating if not diluted correctly.

Always consult with a healthcare provider before using essential oils for oral thrush, especially if you are pregnant, nursing, or taking medications.
