Besides its religious importance, the Bible, because of its ancient origin represents a relevant witness of the way of life of the people mentioned in it. The Holy Scripture is also the first text revealing the utility of plants for man, as natural sources of food, wood, fibers, oils and medicinal herbs. In the last 60 years, several distinguished botanists have attempted to identify the scientific names of the plants cited in the Bible.

The authors have combined their expertise to focus on the identification of the diuretic plants, through an historical analysis of the literature on this issue.
