Roughly chop the fresh calendula flowers and pack them firmly into a mason jar until it is almost full.

Cover the flowers with olive oil and (or the neutral oil of your choice).

Fill a saucepan or slow cooker with 1 inch of water. Place the jar with the oil and calendula flowers on a trivet in the double boiler or slow cooker.

Gently heat the water to 110 to 120°F. Turn off the heat.

For the next 24 to 48 hours, continue infusing the oil by bringing the water back up to temperature. Don’t leave the heat on for a prolonged period, and keep the water about 1 inch deep, adding water as needed.

Once you’re satisfied that the oil is infused, strain the calendula flowers.

Place the oil in a heatproof container (or double boiler) over simmering water.

Add your measured beeswax to the oil, stirring constantly until the beeswax has melted completely and blended with the oil

Pour the finished salve into small glass jars or tins.

Let the salve cool for 30 minutes before using, and keep for up to one year.
