Fill the bottom reservoir of the double boiler with the distilled water.
Fill the top reservoir with the fresh lavender florets.
Cover the boiler and simmer the water and lavender on your stove for 35 to 40 minutes.
Pour the contents of the top reservoir into a glass bowl. Place a mesh strainer over an empty bowl.
Mash the pulpy flowers with the potato masher in the glass bowl, until the flowers form a pulpy wet mess. They will be floating in about an ounce of essential oil.
Pour the contents of the bowl over the strainer. The strainer separates the pulp from the oil as it drips into the bowl.
Add two ounces of coconut oil to the bowl. This lightens the strong essential oil, making it safe for a variety of uses.
Pour the contents of the bowl into a glass oil jar and then secure the cap. The lavender oil is ready for immediate use.
