Hi Tori! That’s a great question! I’m not really sure since I haven’t done much with oregano oil, other than occasional use of Oreganol capsules in the past for really tough colds/sinus stuff for family members. Unfortunately, my husband developed a significant allergy/hives to those! So I don’t do a ton with oregano in general to be able to advise one way or the other on its effectiveness. It’s possible it could work though! :)
