Essential oils are the purest plant oil extraction and are used to create perfumes, massage oils, bug sprays, and in aromatherapy treatments. Traditionally essential oils were distilled using steam distillation machines, however, flowers tend to be too delicate for the distillation process. In the case of rose geranium oil, a gentler approach is necessary.
Harvest the geranium and rose petals and leaves early in the morning to ensure the largest amount of essential oil.
Wash the flowers and leaves gently and pat them dry with the paper towels.
Layer the flowers, leaves and kosher salt in the canister in thin layers. Seal the jar and leave it in a cool, dark place for two months.
Pour out the liquid in the jar and strain it through a cheesecloth. You should obtain roughly 3 oz of essential oil from the canister. Carefully place the oil into a amber dropper bottle and close tightly.
