These days in China, "Dangshen" is popular as a substitute drug for Ginseng. The name of Dangshen can be dated back to Bencaocongxin of the Qing Dynasty. Since then, there have been two theories about the different medical effects between Dangshen and Ginseng. One theory says "Though Dangshen has a benefit of clearing away the lung heat, doctors apply it in substitution for Ginseng so easily and only make the disease worse." The other says "The benefit of Dangshen is equal to that of ginseng." There are some problems about the equality of the medicinal effects.
