Nili Nathan demonstrates how to create your own homemade rosemary facial spray. 1. Start by adding 3 oz of distilled water to a spray bottle. Add 1 tablespoon of olive oil. 2. Take rosemary essential oil and add 6 drops to the bottle. 3. Gather up some fresh rosemary (possibly from your garden or a friends garden or a nearby store) and add that to the bottle. Close the bottle tightly and shake it up. 4. Now you are ready to spray desired amount to body and face!
