Holistic health practitioners prize rose geranium oil for use to help alleviate symptoms of depression, clear oily skin, speed healing and help regulate the hormonal system. However, others value rose geranium oil simply for its intoxicating smell, which can be tailored by picking the leaves at a certain point in their growth. When geranium oil is made from older leaves that have already started to yellow, rose geranium oil has a strong rose sent. But if the oil is made from young, green leaves, the rose geranium oil has more of a lemon-apple scent.
Place 500 mL of olive oil into a clear glass jar.
Submerge as many rose geranium leaves as you can into the oil (or 1/5 of your total supply, if it is limited).
Seal the jar and place it in a sunny spot for one week.
Strain the oil into the second clear glass jar so that the rose geranium leaves are left behind. Squeeze each leaf over the glass jar so that all of the oil is extracted and then compost the leaves.
Submerge as many geranium leaves into the oil as possible (or the second fifth of your supply). Again, seal the jar and leave it in a sunny spot to cure for one week.
Repeat steps 4 and 5 three more times so that the rose geranium oil has cured for a total of 5 weeks, using a fresh batch of rose geranium leaves each time.
Pour the rose geranium oil into a bottle with a stopper. Label it with the bottling date, keep it out of direct sunlight and use it within one year.
