Drinking tea is good for health.

It is divided into two parts. The first part tells about the types of real tea and the making method of matcha. The second part tells about the efficacy and usage of tea corresponding to five diseases: diabetes, stroke, anorexia, sores and beriberi. That is, the Book of Mulberry Tea, which we often talk about, is said to have been written in 12 14 based on the book "The Praise of Tea Morality" written by a general named minamoto no sanetomo, but this statement cannot be verified.

This is the information about this book that I translated from Japanese Wikipedia. I hope it can help you.
