ABSTRACT
Wild ginsengs were originally gathered from many Asiatic and North American sources but continuous overharvesting has now considerably reduced the number of potential gathering areas. Despite this reduction, some wild material is still available commercially. There is, however, no real evidence to substantiate the widely-held folklore belief that the wild product is eminently superior to the carefully cultivated drug. Therefore worldwide supplies are now obtained largely from commercial plantations and considerable knowledge of the problems of cultivation is available.
