Different than a balm in that it is semisolid and is generally 80% Oils and 20% Water. This ratio provides a barrier on the skin and prevents moisture-loss. This also allows a slower delivery of the herbal ingredients.
From: The Master Book of Herbalism by Paul Beyerl
1 oz herbs
16 oz fixative (carrier oil)
heat off and on for 24 hours
Set up a double boiler with your carrier oil. Melt and then add the herbs.
Simmer the mixture on very low heat for a half hour, then strain out the herbs.
Pour into a container and allow to cool and thicken before using.
Keep in fridge to help preserve consistency.
