If you are suffering from muscle cramps, burns, insect bites or even menstrual pain, you can use multani mitti as either a hot or a cold compress. Just mix it with either warm or cold water and apply the paste on the affected area. If you are badly sunburnt and want to soothe your skin, you can apply the paste on your entire body. However, avoid the chest area as this paste is very cold and may give you a cold.
