This recipe from prairielandherbs.com makes a simple yet highly effective body scrub.
1 part salt or sugar
1 part oil
For the salt or sugar: sea salt or raw sugar are best, but you can definitely use plain table salt, white sugar, or brown sugar too.
For the oil: use any mild, unscented vegetable oil - olive, sunflower, safflower, sweet almond, etc. Herbally infused oils work wonderfully too.
Mix ingredients together and scrub onto damp skin; rinse off and pat dry with a towel.
Optional additions: honey, dried or fresh herbs or flower petals, oats, essential oils or fragrance oils.
Note: Sugar scrubs tend to be more mild and less drying than salt scrubs.
