• Fill a saucepan with 1-2 inches of water and place over high heat. Bring to a boil, then turn down to medium-high.
• Place the olive oil, calendula flowers, and chamomile flowers (if using) into a double boiler or glass jar. Set inside the saucepan.
• Allow the mixture to heat on low for several hours. When done, the oil will change color and take on the smell of the herbs.
• Using a jelly strainer held over a glass measuring cup, strain the flower pieces. Squeeze the flowers to get all of the infused oil out.

Crockpot Method

• If you don’t have a double boiler or the supplies to make one, you can use a crockpot.
• Place the ingredients in a glass jar, and set inside the slow cooker.
• Fill the crockpot with 1-2 inches of water, or until half of the jar is covered.
• Let the mixture heat for 4 hours on low, then strain as usual.
