The minerals can
come from salts and clays. You may either purchase the
bath salts or make them yourself. If you decide to make the salts yourself, start with good quality
sea salts. You may also mix them with
Epsom salt. Not all salts are created equal; depending where they came from, the content of minerals changes.
So always shop for only the highest quality
You can purchase them at several high-end
bath and body products websites. You can use about one to half cup of sea salt, two tablespoons of Epsom salts and about 20 drops of
essential oil (pre mix it in a cup of water or 2 tablespoon of
light olive or almond oil). Put everything in the tub and choose the right temperature for you. The essential oils are optional.
