Prepare Your Yarrow: Once dried, place the flowers in a glass jar, filling it to about three-quarters full.
Add the Oil: Pour your chosen carrier oil over the yarrow until the flowers are completely submerged.
Seal and Store: Secure the lid and store the jar in a dark, cool place, such as a pantry shelf away from direct sunlight, to prevent degradation of the oil.
Wait and Shake: Allow the jar to sit for 4-6 weeks, shaking it occasionally to promote the extraction of the yarrow’s medicinal components.
Strain the Oil: Use a strainer or cheesecloth to separate the yarrow flowers from the oil. Press the flowers gently to extract as much oil as possible.
Use Immediately or Store: The oil can be used right away or it can be added to your storage jars and stored in a cool, dark place.
