Blue Salt can be used in Spell work that involves: Protection, healing, wisdom, peace, and dream magick.  Placed under your pillow, it can help you to have vivid dreams or sprinkle a circle of blue salt around a healing candle.  Carried in a sachet, it will help to protect you. 

Salt is a key component in many magickal practices and is considered one of the most sacred minerals on earth. One of the most common magickal uses for salt is creating protective barriers around sacred objects called the "circle of salt."

It can also be used to draw magickal symbols during spell work or rituals. Pour some salt on a tray or plate, and draw your symbols in the salt. There is no need to discard the salt when you are finished with your spell; you can pour it back into its container and use it again and again.
