Most essential oils are good for a persons sore throat but the essential oils that I find that work best for getting rid of my sore throat are Peppermint, Lavender, Tea Tree and lemon essential oils.
You can use just about any essential oils that you want in an essential oil diffuser to help treat and get rid of your sore throat but I find that those are the ones that work best for me and I love to use different ones to mix it up.
