Refreshing herb Rosemary is native to the Mediterranean region but today you can find it everywhere. Rosemary oil has been used for its healing, medicinal and psychological effects for centuries. Research has shown that an antioxidant rosmarinic acid obtained from rosemary could possess neuroprotective effects in neuroinflammation and oxidative stress .
Although rosemary essential oil is now made by extracting the natural oils from herbs or flowers using advanced techniques, centuries ago simple oil infusion was used.
Here is a simple recipe to make Rosemary oil at home. All you need is dried Rosemary, olive oil and a nice warm corner of your house. You can use rosemary infused oil as a body oil or a hair mask. If you prefer, you can use rosemary-infused olive oil in salads, dips etc.
Rosemary-infused olive oil recipe
1- Fill a clean, dry, glass jar around two-thirds full with dried Rosemary. Do not pack the Rosemary and leave it loose so the oil will have enough space to cover the herbs.
2- Completely immerse the rosemary with high quality extra virgin olive oil. Cover the herbs with oil so they will not be exposed to air. If you like you can use grape seed, apricot, sunflower, or other liquid plant oils instead of olive oil. If you are going to use the rosemary oil in foods, olive oil is the best choice.
3- Remove the air pockets in the jar by gently stirring the mixture.
4- Close the jar tightly. Leave the jar for two to four weeks in a warm location. Gently shake the jar every couple days. Make sure the rosemary remains immersed in oil.
5- After two to four weeks, to get every bit of the rosemary out of the oil, strain the mixture through a few layers of clean, dry cheesecloth. Repeat the straining process until your oil is clear.
6- Transfer your rosemary-infused oil to a clean, dry glass bottle or jar. Let the oil settle for a week in a dark cool place. During this time, if there are any impurities generated from the plant material to settle at the bottom of the bottle. If there is any water coming from the plant, it will rise to top. Remove any oil/water mixture on the top.
7- Strain it through a clean cheesecloth to a clean jar. Label and store your rosemary oil in a dark cool place until use.
