Tui Rose, as a concerned mother and registered nurse interested in family and pet health and environmental safety, could not find a book anywhere in the USA or western world on the safer alternative Diatomaceous Earth for consumer usage. So Tui decided she must write one herself and fill the literary void. She spent 15 years researching and writing to eventually produce this useful guidebook with the shared help of hands-on skilled and knowledgeable users in their various fields--harvesting nearly 50 years of their personal experiences and expertise. As a result, this practical resource book is the first of its kind for consumers on the topic of Diatomaceous Earth.
