I’ve made salves with coconut oil before using the crockpot method described in this tutorial here. Just sub in calendula for lavender herb. https://www.theherbalspoon.com/2014/02/diy-lavender-salve-all-natural-and.html

I would like to use coconut oil with this. Like you said, it solidifies at room temp. You mentioned shaking it a few times a day, but won’t it solidify even on a window seal? Is that ok or do we need to make sure oil is always liquid? Thanks!

Thankfully it is super easy! The shelf life all depends on what carrier oil you use, coconut oil has one of the longest. You can also add 1/4 teaspoon of vitamin E oil to prevent the oil from oxidizing and going rancid faster. Altogether I would say you’re looking at a year or two of shelf life.
