This is my plan for some of the lard we'll make from the boar heading to butcher here shortly. Our comfrey just woke up and is taking over the raised bed again. Do you add anything else besides the fat and comfrey like bees wax? I've been adding oregano oil to my Dr. Cristophers and it seemed to help heal even faster.
Making some comfrey salve with tallow today. So far I’ve only used coconut oil. The tallow is from a farm here in town as well as the beeswax. I love using ingredients that are only a few miles away. We freeze dry the comfrey leaves after picking from our property. We still have a few tins left in the Etsy shop which are also available to purchase with lightning #comfreysalve #grownostr https://www.etsy.com/listing/1324072877/

Nice! I do also add a few drops of vitamin E to the salve
