Fig. 5From: Conservation and sustainable use of medicinal plants: problems, progress, and prospectsPrice and harvest volume variation in the transition from wild-harvesting to cultivation of medicinal plants. As wild resources decline with overharvesting, the price of raw material increases accordingly. Therefore, cultivation becomes economically feasible for price stabilization and resource recovery of medicinal plants. Data sources from Hamilton [4], Larsen and Olsen [13], Schippmann et al.
