I just posted few seconds before you did about Leo Kiesen book. For ZenMed info you can check this link: http://www.natural-acne-treatments.com. It actually says Zenmed worked for most people but only for awhile. It tells you that ZenMed herbal formula works and you really don't need to use topical stuff if your budget is low. There is free info on the page which I thought was pretty interesting.
