How to Make Essential Oils

Although some recipes may vary, the basic rule of carrier oil to herbs or flowers is one cup of carrier oil to every 1/4 ounce of dried herbs or flowers. If you are using fresh flowers or herbs, place them in a plastic bag and gently hit them with the wooden mallet and gently bruise the plant matter. The ratio for using fresh flowers or herbs is one cup of carrier oil to 1/4 cup of flowers, leaves or other plant materials.

Basic Steps

  • Choose one of the following methods to blend your essential oil:
    • Crock Pot Method - Place the oil and the herbs in the crock pot on its keep warm setting, approximately 140 degrees Fahrenheit, for six to eight hours.
    • Oven method - Place the oils and herbs in the oven set on very low, 150 degrees Fahrenheit, for two hours.
    • Sunlight method - Place the oils and the herbs in a mason jar and place the closed jar in full sunlight for a minimum of 14 days. The Mason jar must have a rubber ring as using a metal ring contaminates the essential oil.
