Fill the jar with olive oil, stir well and close the lid of the jar.
Now, fill a container with water and bring it to a boil.
Place the jar in this container and let the water boil for another 10 mins. When you place the jar into the hot water, the oil inside the jar heats up and releases the natural oil from the oregano leaves.
Remove the jar, shake it, and store it in a dry area for 1-2 weeks. Keep shaking the jar at least once every day.
Strain the oil into another airtight container and use it as per requirement.
You can store the excess oil in a dark dry place for nearly a month.
You may substitute olive oil with almond oil or grapeseed oil.
