"the plant 'Peucedanum japonica' has been noted as a hallucinogenic plant. The root is used in Chinese medicine as a diuretic, sedative, and tussic but is however slightly deleterious in nature. Tao Hung-chin says that ' Feverish people should not take it, because it causes one to be delirious and see spirits.' Ch'en Yen-chih says that 'Fang-k' uei, if taken in excess, makes one become delirious and act somewhat like mad.'"
