天门冬，生长在奉高山的山谷中，如今各地都有生长。春天生出藤蔓，粗细像发钗的股部一样，高度可达一丈多，叶子像茴香，极其尖细且疏滑，有逆生的刺，也有涩而无刺的，其叶子像丝杉那样细碎分散，都称为天门冬。夏天开出白花，也有黄色的；秋天结出黑色的果实，长在根枝旁边。进入伏天后不再开花，暗中结出果实。它的根部是白色的，也有黄紫色的，大小如手指，长度二、三寸，大的为好，颇与百部的根相似，但更圆实且长，通常一二十枚聚集在一起。二月、三月、七月、八月采集根部。将其劈成四瓣，去掉心，先蒸半个做饭的时间，然后晒干。存放久了仍然会湿润，入药时，需重新烘烤焙干使其干燥。洛阳出产的天门冬，叶子大秆粗，与其他地方的截然不同。岭南出产的天门冬没有花，其余没有别的差异。谨按天门冬的别名，《尔雅》称它为蘼（亡彼切），一名颠冬。《山海经》说：条谷的山上，那里的草多芍药和颠冬，就是这种植物。《抱朴子》及《神仙服食方》说：天门冬，又名颠棘。在东岳叫淫羊藿，在中岳叫天门冬，在西岳叫管松，在北岳叫无不愈，在南岳叫百部，在京陆山阜叫颠棘，虽然到处都有，名称各异，但实质是一样的。在北岳背阴处的尤其好，想要服用它，切成细丝，阴干，捣碎过筛，用酒调服三钱匕，每天五、六次服用，二百天见效，可以强壮筋骨骨髓，驻留容颜，与炼成的松脂混合蜜丸服用更好。服用者不可吃鲤鱼，这个方子以颠棘为别名。而张茂先认为它是异类。《博物志》说：天门冬茎间有刺，而叶滑的叫休，又名颠棘，其根可以用来洗绢素使之变白。越人叫它浣草，形状像天门冬但不是。凡是服用此药，先试着用它洗衣服如果像上述方法那样能洗白，那就不是天门冬。如果像所说的那样，有刺而叶滑，就不能用来服用。然而现在所有的，往往是这类情况，使用者必须仔细辨别。
Liu Zhi (Six Mushrooms), detailed under the entry for Chijian (Gastrodiae Rhizoma).
Tianmendong (Asparagi Radix) grows in the valleys of Fenggao Mountain, and is now found everywhere. In spring, it produces vines as thick as the shaft of a hairpin, growing up to over one zhang high. The leaves resemble those of fennel, being extremely sharp, fine, sparse, and smooth; some have reverse-pointing thorns, while others are rough without thorns. Their leaves are fine and scattered like those of silk fir, all referred to as Tianmendong. In summer, white flowers appear, sometimes yellow; in autumn, black berries form beside the root branches. After entering the Fu days (the hottest period of summer), no flowers appear, and fruits form secretly. The roots are white or yellowish-purple, as thick as a finger, two to three cun long; larger ones are superior. They somewhat resemble the roots of Baibu (Stemonae Radix), but are rounder, solid, and longer, usually gathered in clusters of ten to twenty. Roots are harvested in the second, third, seventh, and eighth lunar months. They are split into four pieces, the core removed, steamed for half the time it takes to cook a meal, and then sun-dried. If stored for a long time and become damp again, they must be re-roasted and baked dry before use in medicine. Those from Luoyang have large leaves and thick stems, quite different from others. Those from Lingnan do not flower, otherwise there are no other differences. According to records on the aliases of Tianmendong, *Erya* calls it Mi (pronounced wangbi), also known as Jidong. *Shan Hai Jing* states: "On the mountains of Tiao Valley, the herbs include Shiyao (Paeoniae Radix Rubra) and Jidong." *Baopuzi* and *Shenxian Fushi Fang* state: Tianmendong is also called Dianji. On Mount Dong (East), it is called Yinyanghuo (Epimedii Folium); on Mount Zhong (Central), it is Tianmendong; on Mount Xi (West), it is Guansong; on Mount Bei (North), it is Wu Buyu; on Mount Nan (South), it is Baibu; on the hills of Jinglu, it is Dianji. Although found everywhere with various names, they are essentially the same. Those grown in the shade on Mount Bei are particularly good. To consume it, slice finely, dry in the shade, pound and sieve. Mix three qianbi with wine and take five or six times daily. Effects will be seen after 200 days, strengthening sinews and marrow, preserving complexion. It is beneficial to combine it with refined pine resin in honey pills. Consumers must avoid eating carp. This prescription uses Dianji as an alias. Zhang Maoxian considered it a different species. *Bowuzhi* states: Tianmendong has thorns on its stems, and if the leaves are smooth, it is called Xiu, also named Dianji; its roots can wash silk white. People in Yue call it Huanc grass, which resembles Tianmendong but is not it. To test if a plant is truly Tianmendong, try washing clothes with it according to the method; if it whitens the fabric, it is not Tianmendong. If it has thorns and smooth leaves as described, it is unsuitable for consumption. However, what is currently available is often this type, so users must examine it carefully.
