Spermaceti ointment, 1/2 ounce, Balsam of Peru, 7 1/2 grains, Alkanet, 7 1/2 grains, Oil of cloves, 2 drops.
Mix the alkanet with the spermaceti ointment, in a bottle or in a dish, and let it stand over a gentle heat till the liquid is rose-colored, then put it through a strainer. When cool, stir in the balsam and let it settle.
When it is clear pour off the liquid, leaving the sediment, then add the cloves to the liquid. When it becomes cold, it should be hard, but it will not get hard if in the course of making it has been subjected to too much heat; therefore, it should simply be allowed to get warm.
