Bath Salts are a simple way to let someone know you think they are special or to give a touch of extra care when they are not feeling well.
Take some simple ingredients: Epsom Salts (this large container from Sam's Club was less than $7), Sea Salt, Baking Soda, Oil, and Essential Oils.
Mix the dry ingredients well. Then add the oils. Store in a glass jar.
I used the Long Winter Bath Salts recipe in an article at articles.beeyoutiful.com by Jill Krantz.
