（连翘）生长在州、曹州、兖州等地。如今在钧州、新郑的沙岗之间也有生长。它的苗和叶子贴近地面丛生，叶片形状像山芥菜的叶子但更大，且分叉较多，也像白屈菜的叶子，又像大蓬蒿的叶子，还像风花菜底部的叶子但更大。叶片中间抽出葶茎，上面开红花和白花。根和苗的味道苦咸，性质寒凉，无毒。连翘作为其引经药（使药）。
【食用方法】采摘叶片，用开水焯熟，用水浸泡并淘洗以去除苦味。加入盐和油调味后食用。【药用价值】详见本草著作。
龙胆草 又名龙胆，又名陵游，俗称草龙胆。生长在齐地朐山山谷以及冤句、襄州、吴兴等地都有分布。如今在钧州、新郑的山岗之间也有生长。根部类似牛膝，但一根主根上长出十余个茎秆，为黄白色的多年生根。苗高约一尺多，叶片像柳叶但更细短，又有点像小竹子。开花像牵牛花，呈青碧色，形状像小铃铛。陶隐居注释说：形状像龙葵，味道苦得像胆汁，因此得名。味道苦，性质寒凉，大寒，无毒。贯众、小豆作为其引经药（使药），畏忌防葵、地黄。又说浙江中部又有山龙胆草，味道苦中带微甘，这是同类但不同的品种。
(Lianqiao / Forsythiae Fructus) grows in Zhou, Caozhou, and Yanzhou. Currently, it is also found in the sandy ridges of Junzhou and Xinzheng. Its seedlings and leaves grow densely close to the ground. The leaves resemble those of *Brassica juncea* var. *tumida* (Shan Jie Cai) but are larger, with many branches. They also resemble the leaves of *Chelidonium majus* (Bai Qu Cai), *Artemisia vulgaris* (Da Peng Hao), or the lower leaves of *Brassica rapa* var. *parachinensis* (Feng Hua Cai), but are larger. Red and white flowers bloom on the scape rising from the center of the leaves. The roots and seedlings taste bitter and salty, are cold in nature, and are non-toxic. Lianqiao serves as its guiding herb (shi).
[For Sustenance] Harvest the leaves, blanch them in boiling water, soak in water, and rinse to remove the bitterness. Season with salt and oil for consumption. [For Treating Diseases] Refer to Materia Medica texts.
Longdancao (Gentianae Radix et Rhizoma), also known as Longdan or Lingyou, commonly called Caolongdan. It grows in the valleys of Qushu Mountain in Qi, as well as in Yuanju, Xiangzhou, and Wuxing. Currently, it is also found in the mountain ridges of Junzhou and Xinzheng. The root resembles *Achyranthes bidentata* (Niuxi), but a single main root produces over ten stems; it is a yellowish-white perennial root. The seedlings are over one chi tall. The leaves are slender and shorter than willow leaves, resembling small bamboo shoots. The flowers resemble those of *Ipomoea nil* (Qianniuhua), are blue-green in color, and bell-shaped. Tao Hongjing noted: "Its shape resembles *Solanum nigrum* (Longkui), and its taste is bitter like gall, hence the name." It tastes bitter, is cold in nature, greatly cold, and non-toxic. Guanzhong (*Cyathulae Radix*) and Xiaodou (Adzuki Bean) serve as its guiding herbs (shi). It is incompatible with Fangkui (*Anemarrhenae Rhizoma*) and Dihuang (*Rehmanniae Radix*). It is further stated that in central Zhejiang, there is also Shanlongdancao, which tastes bitter with a slight sweetness; this is a similar species but distinct.
