It's not only very useful for sorcery. It's very grounding to a person if you soak in a sea salt bath it soaks out negative energy. The ocean is like that too. It's very grounding for a person. Try the bath on a Thursday before a full moon.
Take a second bath that day in Olive oil, It seals the positive energy in you and you'll feel very calm.

I don't get into socery but I find herbs and natural oil to be very healthy for meditation.
