【茵陈蒿】
味道苦，药性平、微寒，无毒。主治风湿寒热等邪气，以及热结导致的黄疸。治疗全身发黄、小便不利，消除头部热邪，去除体内潜伏的积块（伏瘕）。长期服用可使身体轻盈，益气，延缓衰老，面色红润悦泽，延年益寿。白兔食用它，可以成仙。生长在泰山及丘陵坡岸上。五月及立秋时采集，阴干。
现在各地都有，形状像蓬蒿但叶子紧细。茎部冬天不死，春天又生长。只用于入药治疗黄疸。《仙经》说：白蒿，白兔食用它，可以成仙。而现在的茵陈蒿却说就是这种植物，恐怕是搞错了。（《大观本草》卷七，《政和本草》一八八页）
【漏芦】

乔山应该是黄帝安葬的地方，位于上郡。现在近道也有出产，治疗各种疥癣，长期服用对人非常有益，但在服食方中很少使用。
现在市井之人多取用其苗。世人中取用根部，名为鹿骊根，用醋研磨，用来治疗疮疥。（《大观本草》卷七，《政和本草》一八一页）

这就是现在用来染绛红色的茜草。东部地区各处虽有但较少，不如西部多。当今的道经医方中不常服用它。这应当是因为它被用作……

Currently found everywhere; resembles Artemisia capillaris but with tighter, finer leaves. The stems do not die in winter and sprout again in spring. Only used in treating jaundice. *Xian Jing* states: "White mugwort, if eaten by white rabbits, leads to immortality." However, current Chen Yin Hao is identified as this plant, which is likely an error. (Da Guan Ben Cao Vol. 7, Zheng He Ben Cao p. 188)
