时珍曰∶《尔雅》∶蔚，牡 ，蒿之无子者。则牡之名以此也。诸蒿叶皆尖，此蒿叶独

恭曰∶齐头蒿也，所在有之。叶似防风，细薄而无光泽。
生苗，其叶扁而本狭，末 有秃歧。嫩时可茹。鹿食九草，

【集解】颂曰∶生筠州山冈上。二月生苗，独茎，高一尺。叶似艾叶，圆而长，背有白
毛，面青。五月采苗用。
时珍曰∶陈嘉谟《本草蒙筌》以此为蕲艾，谬矣。
苗
【气味】微苦，有小毒。
【主治】解风劳，治身体痛。与甘草同煎服，不入众药用（苏颂）。
（宋代《图经本草》）
【集解】苏颂说：生长在邓州顺阳县内乡的山谷中。叶子像青蒿，茎呈青紫色，花结成小穗状，颜色微黄，根像细辛。七月采集根和苗使用。
李时珍说：江浙地区也有这种植物。外地人采集它来炼制丹砂、硫黄。
根和苗
【气味】味甘、苦，性微寒，无毒。
【主治】肿毒风热（苏颂）。
【附方】新录一方。
男女吐血之后，胸膈部虚热：阴地厥、紫河车、贯众、甘草各半两。每次服用三钱，用水煎服。（出自《圣济总录》）
（《神农本草经·别录》下品）
【释名】齐头蒿。
李时珍说：《尔雅》记载：“蔚，是牡蒿，即不结种子的蒿。”所以“牡”这个名字由此而来。各种蒿的叶子都是尖的，只有这种蒿的叶子顶端平秃，所以有“齐头”的名字。
【集解】《别录》说：牡蒿，生长在田野里。五月、八月采集。
陶弘景说：现在方药中不再使用。
甄权说：就是齐头蒿，各地都有生长。叶子像防风，细薄而没有光泽。
刚长出的苗，它的叶子扁平且基部狭窄，末端有平秃的分歧。嫩的时候可以吃。鹿吃的九草之一，就是这种。秋天开细小的黄花，结的果实大如车前子，但里面的种子极细微看不见，所以人们认为它没有种子。
苗
【气味】味苦、微甘，性温，无毒。
【主治】充实肌肤，益气，使人突然发胖。不可长期服用，否则会导致血脉满盛（《别录》）。研磨取汁服用，治疗阴部肿胀（李时珍）。
【附方】新录一方。
疟疾寒热往来：齐头蒿根、滴滴金根各一把。用一杯生酒研磨后服用，在发作前服用。将药渣敷在寸口脉处，男性左手，女性右手。
（宋代《图经本草》）
【集解】苏颂说：生长在筠州的山冈上。二月长出苗，独茎，高一尺。叶子像艾叶，圆形而长，背面有白色绒毛，正面青色。五月采集苗使用。
李时珍说：陈嘉谟在《本草蒙筌》中将其认为是蕲艾，这是错误的。
(Song Dynasty *Tu Jing Ben Cao*)
[Collected Explanations] Song said: It grows in the valleys of Neixiang, Shunyang County, Dengzhou. The leaves resemble those of *Artemisia annua* (Qinghao), the stems are bluish-purple, the flowers form small spikes and are slightly yellow, and the roots resemble *Asari Radix et Rhizoma* (Xixin). The roots and shoots are harvested in July for use.
Shizhen said: It is also found in the Jiangsu and Zhejiang regions. People from other places harvest it to refine cinnabar and sulfur.
Roots and Shoots
[Aroma and Flavor] Sweet, bitter, slightly cold, non-toxic.
[Indications] Swelling, toxicity, wind-heat (Su Song).
[Attached Prescriptions] One new prescription.
For men and women experiencing deficiency heat in the chest and diaphragm after hematemesis: *Hemerocallis citrina* Bulbus (Yindijue), placenta (Ziheche), *Cyathulae Radix* (Guanzhong), and *Glycyrrhizae Radix et Rhizoma* (Gancao), each half liang. Take three qian per dose, decocted in water and taken orally. (*Shengji Zonglu*)
(*Ben Cao Jing Bie Lu*, Lower Grade)
[Names] Qitouhao.
Shizhen said: *Erya* states: "Wei is Mu Hao, which refers to mugwort that does not produce seeds." Thus, the name "Mu" originates from this. The leaves of various muggorts are pointed, but the leaves of this mugwort are uniquely flat-topped and bald, hence the name "Qitou" (Flat-headed).
[Collected Explanations] *Bie Lu* states: Mu Hao grows in fields. It is harvested in May and August.
Hongjing said: It is no longer used in medical prescriptions.
Gong said: It is Qitouhao, found everywhere. The leaves resemble those of *Saposhnikoviae Radix* (Fangfeng), being thin and lacking luster.
The young shoots have leaves that are flat with a narrow base and flat-tipped branches at the ends. They can be eaten when tender. One of the nine plants eaten by deer is this one. In autumn, it opens small yellow flowers; the fruit is as large as *Plantaginis Semen* (Cheqianshi), but the seeds inside are too minute to be seen, so people believe it has no seeds.
Shoots
[Aroma and Flavor] Bitter, slightly sweet, warm, non-toxic.
[Indications] Fleshes the body, benefits Qi, causes sudden obesity. It should not be taken for a long time, as it may cause fullness and excess in the blood vessels (*Bie Lu*). Taken as a pounded juice, it treats genital swelling (Shizhen).
[Attached Prescriptions] One new prescription.
For malaria with alternating chills and fever: Roots of Qitouhao and Didingjin, one handful each. Pound them with one cup of raw wine and take before the onset of symptoms. Apply the dregs to the Cun Kou pulse point, on the left hand for men and the right hand for women.
(Song Dynasty *Tu Jing Ben Cao*)
[Collected Explanations] Song said: It grows on hillsides in Yunzhou. Shoots emerge in February, with a single stem about one chi high. The leaves resemble *Artemisiae Argyi Folium* (Aiye), being round and long, with white hairs on the back and green on the front. The shoots are harvested in May for use.
Shizhen said: Chen Jiamo considered this to be Qiai in his *Bencao Mengquan*, which is erroneous.
Shoots
[Aroma and Flavor] Slightly bitter, slightly toxic.
[Indications] Resolves wind-lao (chronic deficiency due to wind), treats body pain. Decocted and taken with Gancao, it is not used in combination with other herbs (Su Song).
