Oooh, I love Castile soaps!!!! And no- they’re not just body wash… they can be used for a million different things! You can get them in solid bar soaps or in liquid versions at any health food store. They’re not just an organic soap - the natural ingredients are designed to be effective for treating any skin condition (acne to eczema). They are created from natural plant oils and extracts (olive oil, jojoba oil), so not only are they great cleansers, but they are also quite moisturizing.
They’re gentle enough to use on a baby’s skin; you can use them as bubble bath, shampoo.. even pet wash or laundry soap!
Liquid soap is more universal because you can easily add it to water to dilute it and put it to many uses, as I listed above. Solid bar soap would be best if you were intending to use Castile soap simply as a cleanser or body wash. :)
