Publisher's Synopsis
Medicinal plants have been cultivated in the United States for more than two centuries. Only a few decades have elapsed since healing herbs shared with small fruits and vegetables a place in every kitchen garden, and in certain localities their production and sale at one time formed the basis of small industries. In time, however, the numerous convenient preparations obtainable at every drug store rendered the domestic herb garden no longer necessary, and the great development of foreign commerce made it possible to obtain supplies of most crude drugs from sources where the cost of production was less than in this country.
