Ostioarthritis, Sinusitis, Cold Sores

I love your oragano oil for the pain relief it gives my husband who has ostioarthritis in his back hips and knees. I applie it to my cold sores when I get one and it kills them dead. I also us it for pain. When my husband first started using it he had bad sinusitus it gave him relief with in 3 days of taking it.
