The era of plants, in which they enjoyed life in deep communion with humans, came to an end with the advancement of science.
As modern science has dispelled inaccurate perceptions and superstitions about nature, plants have come to be viewed only as objects of food and commercial value, to be used, utilized, and exploited by humans.


But as the realization that humanity could not survive without the "green canopy" of these plants that surround our world has become increasingly widespread, the spiritual relationship between the green world and the human world, buried in lost traditions, has begun to be re-evaluated.


The author draws on a wide range of archaeological knowledge and data related to plants to explain how plants relate to culture and customs.
It introduces a variety of plants used for various purposes, including medicinal herbs, poisonous plants, coffee and tea, and drugs, and captures our attention with vivid and colorful photos.
