My grandmother gave me an oregano essential oil. She told me that she also uses this essential oil, and it is the reason why she barely gets sick. I found out that the oil is used when someone has an infectious illness. It has the ability to kill different pathogens. At first, I did not believe my grandmother. But after I read all the good things that it can do for me, I decided to give it a try. I am very happy with how it is helping me fight off pathogens that used to disrupt me in my daily activities.
