This powder is awesome to use in the hot summer months when prickly heat/rash breaks out on the body due to excessive perspiration. It's best to stay cool at such a time. To do that, use this powder to stay cool and dry. I like to make a batch of this and store it in my refrigerator, so that when I apply this, I feel light and cool!Also, wear light clothing made from natural fibres such as cotton. My mom has always made me a new cotton lingerie ever since I can recall for every summer:-) This recipe is from the book Natural Beauty At Home by Janice Cox.
