～The book is about the tremendous effects of inutouki, a rare endangered species (Category II).

The developer, author, and president of our company, Hayashi himself was saved from a kidney disease by the endangered Class-II plant "Inutoki" and focused on this plant. Inutoki" is a rare plant (endangered species) that is not easy to cultivate, takes 5 years to grow to its medicinal potential, and is grown with measures to prevent root rot during cultivation.

Since kidney disease is one of the top factors that shorten the life span of cats and dogs, we are convinced that we can extend their life span by utilizing <Endangered Class II Plant "Inutoki" >, and started research and development under the guidance of veterinarians. As a result of tests on dogs and cats with diseases, dramatic improvement was recognized, including an 83% improvement rate in kidney function.
