You can use it on your skin: It's thought that oregano oil is helpful for skin conditions like cold sores, muscle aches, nail fungus, joint pain, and dandruff. Try diluting it with a carrier oil like jojoba, sweet almond, or grapeseed, at 10 to 12 drops oregano oil per ounce of carrier oil.
Increase oven temperature to 400 degrees F (200 degrees C), and continue baking 15 minutes, to an internal temperature of 160 degrees F (70 degrees C). In a small bowl, mix the remaining tomato sauce and ketchup. Pour over the top of the meatloaf, and continue baking 10 minutes.
Depends on how big it is. As a rule you should cook a 5lb meatloaf in a loaf pan for about 1 and a half hours at 325F. Cover with foil unless you put ketchup or catsup on top â¦ of it-you can brown it wen it's cooked. 2.5 pound meatloaf should be cooked for approximately 1.5 hours  in a preheated 350 degree oven. Cook until the inside of the  meatloaf is 170 degrees or until the juices â¦ are no longer pink or  red.
