This product has proven to me to be a safe and fast working relief from the terrible cold sores I experience. My cold sores often form at those most inopportune times and hold me hostage to feeling insecure and embarassed at the unsightly bump on my lip. Using oil of oregano has been a saving grace! As soon as I get the tingle of a cold sore I apply a drop onto my lip. I apply it 3-4 times daily. My usual medication, prescribed from a general practitioner, worked over a 5-7 day timeline (so really the virus just runs it’s course). With Oil of Oregano my last few cold sores have only been present for days, they have decreased in size and heal without any mark. Truly A great product!
