Commercial bath salts will do absolutely nothing on an esoteric level – they have too many chemical additives and artificial perfumes – so it is a nice touch to make your own, using single essential oils, blends, and/or herbs. The fact that you have mixed them yourself means they are infused with your vibration and therefore will work on a very subtle level. If you are using a blend of essential oils it is wise to mix them first, to allow the synergy between the oils to develop. Matching your bath salt perfume to your incense perfume does wonders for your inner self.

YOU WILL NEED:
3 parts Epsom salts
2 parts baking soda
1 part rock salt (or borax)
Bowl for mixing
Natural food coloring
Ritual bath oil blend
Handful of herbs (optional)
