what is the best method to prepare lavender oil?

Answer 1

Place 1 cup Lavendar and 2 cups oil in the glass bowl over a pot of simmering (not boiling) water.
Cover & simmer over low heat for about 3 hours.
Strain into a bowl. Let the oil cool, then transfer into dark, glass bottles sealed with a cap. Store in a cool, dark place.
Any vegetable oil will do, yet olive, almond, canola, and sesame oils are the best.

OR...
Fill a clear glass jar with 3-4 cups crushed dried flowers, petals or leaves. Pour in 4 cups olive oil until it completely covers the herbs. Close the jar and shake well. Place the jar in a sunny location and shake everyday for 2-6 weeks. Strain the herbs with cheesecloth and squeeze out all of the remaining oil. Pour your infused oil into dark glass bottles.
Olive oil works well for cold infusions because it rarely becomes rancid.
Crushing the lavendar makes a stronger infusion.
