There are a few different ways to make herbal infused oil. We chose to infuse calendula petals in olive oil using cold-infused method. Here are the basic steps.
What you need
glass jars with lids
Fill a glass jar halfway with calendula petals.
Pour olive oil over the flowers, covering them at least 1 cm.
Stir to release air bubbles. Shake daily for a period of 2-6 weeks. Strain and store for use!
