If using herbs, add them to the animal fat and allow them to infuse for several weeks in a cool, dark place. Then strain them out.
Add the animal fat and beeswax into a double boiler and heat until just melted. Immediately pour into salve tins.
Allow the salve to harden for about 2 hours before use.
Notes
This salve can be made as a herbal salve simply by infusing the fat with herbs of your choice. Be sure to strain the herbs out of the fat before making the salve.
