How to use: add a pea size (or larger depending on the size of the lesion) and Black Seed Oil to the area you want to treat, followed by same size castor oil. Dab on twice daily until gone (no need to cover).
FYI: if you have a pretty deep cyst or boil, you might want to add a little Retin-A, or amlactin lotion first to draw out, and bring to the surface. Then dab the black seed oil followed by castor oil last.
For regular barnacles - black seed oil followed by castor oil
