Multani mitti was one of the earliest substances to ever be used as a beauty mask. It consists of a lime-rich clay from the far northwestern region of India, rice bran, and milk. Although it is an effective clay for improving the facial complexion, it is also used to draw toxins from the skin of the entire body. Scientifically, it has been shown to be bacteriostatic against gram positive bacteria; it can even be administered internally in cases of poisoning to decrease the absorption of the harmful substance.
