I made mine using the quick, stovetop method because I was in a hurry.
I first tore up the comfrey leaves into small pieces and covered them with the olive oil. I used a heat proof glass jar. A measuring cup or canning jar works great.
I sit the glass cup that contained the olive oil and comfrey in a pan of water and brought it up to a temperature of 140 degrees F. I kept it at this temperature for about 3 1/2 hours.
I then strained the oil, removing the comfrey leaves.
I added the beeswax (pre-measured) to the oil and let it melt. The larger the chunks of beeswax, the longer it takes to melt. I did stir the mixture continually while waiting for it to melt.
Once the beeswax was melted, I removed it from the heat, added in the essential oils and the vitamin E and stirred the mixture to make sure everything was well combined.
I quickly poured the liquid salve into containers. The small 4-ounce canning jars work great or you can buy metal containers with lids if you prefer.
I set the containers aside without lids to allow the salve to harden.
Once it was hard, I labeled it, put a lid on it and use it daily after milking. I simply scoop out a small amount (around a half a Tablespoon) and massage it all over their udders.
