This recipe came from "The Body Bible" by Pamela Allardice. I use it often and it is really cheap and works well even on very sensitive skin (like mine). I buy my kaolin clay from a ceramics supply shop and it is very cheap...I think the last time I bought it i paid about $3.50 for 5kg (about 11 lbs). I sometimes add thyme to the parsley, this is good for loosening blackheads. Make sure you use course ground almond meal, the last meal I bought was fine and it doesn't work anywhere near as well as the course stuff.
