Salt Scrub
A salt scrub provides a more concentrated cleansing. For maximum effect, add bath salts to the water and then apply the salt scrub directly to the body.
The Standard Salt Scrub formula consists of a blend of approximately one cup of salt and one half cup of oil. The actual quantity depends, however, upon the desired consistency and the sensitivity of your skin: if you’d like a softer, less abrasive scrub, increase the proportion of oil.
Because salt is purifying and protective, every salt scrub inherently provides aura cleansing. However, the purpose and added effects of a salt scrub may be adjusted through the addition of essential oils. Rosemary, clary sage, frankincense, manuka, benzoin, thyme linalool, and sandalwood all intensify the cleansing effect.
