Isatis tinctoria
The road had a large economic significance for interregional trade and bartering. From the west came Flemish blankets, from the east wood, pelts, wax and honey, and the middle section controlled the German indigo ("Isatis tinctoria") of the Thuringian Basin as well as the mining products of the Saxon Ore Mountains. The High Road also provided the direct route between the largest German trade fairs of Frankfurt and Leipzig.
