Ingredients:

  • 1/3 pint (0.33 pint) Carrier Oil of your choice, see written for info
  • 1 oz (1 oz) Rosemary dry is best, but fresh is fine

Equipment:

Instructions:

  • Place the dried rosemary into a clean, airtight jar, a mason jar would be perfect.
    1 oz Rosemary
    Dried rosemary is poured into a mason jar
  • Fill the jar with your chosen oil. The rosemary must be completely covered with oil, and at least an inch above. If the rosemary is above the oil it will be prone to mold.
    1/3 pint Carrier Oil
    Carrier oil is poured into the mason jar
  • Place the cap tightly onto the jar and give it a good shake. Then pop the jar in a warm sunny place for two to three weeks to infuse. Whilst the oil is infusing it will need to be shaken once or twice a day. Keep an eye on any rosemary stems that may float above the oil. If they look like they are starting to mold or decay remove them.

  • Two or three weeks later, when the rosemary has been fully infused into the oil, it's time to strain it. You can use a fine strainer or a piece of cheesecloth to strain the rosemary out of the oil. You may need to squeeze it through the cheesecloth several times to fully strain the oil.

  • If you are using this for cosmetic purposes only, We recommend adding 1% vitamin E oil to help preserve the rosemary oil. This would extend the oil's shelf life to around 6 months. Lable and store the oil in a cool dark place, and use as needed.
