Since the dawn of time, the life of humans and that of plants have been inextricably woven together, with every aspect of a human being's life being dependent upon the plants. For tens of thousands of years, plants have provided us with clothing, shelter, food, fuel, textiles and countless other necessities of living.
Human beings breathe in oxygen and breathe out carbon dioxide.
In turn, plants breathe in carbon dioxide and breathe out oxygen-our most precious resource. If there were no plants, there would be no life. It's as simple as that. This is a physical reality that too many fail to recognize in our modern lives. Over the last one hundred years, Americans have lost touch with their herbal medicines, and the United States is unique in being one of the only nations to have almost completely lost its herbal tradition.
