Hulda Clark does a great job revealing how people get sick with parasites and pollutants and that these are the cause for virtually every illness including cancer and HIV. Then she explains how easy it is to identify the intruders and then rid the body of these intruders. Hulda packs the book with a lot of information about her research and how to use a syncrometer and a zapper and what to do to live a healthy lifestyle. If you’re interested in alternative medicine, this is definitely worth a read.
