五种针具图式：
平半寸针。长一寸六分，针头大针尾尖。用于病在皮肤的热证，现今称为箭头针。
其三棱形针。长一寸六分，用于顽固性疾病，刺较大病灶时使用，现今称为三棱针。
破皮针。又名剑针，针末如剑锋，宽二寸，长四寸。用于切开皮肤，排出痈肿脓液。
另一种针。针尖圆而锐利，末端稍大，长一寸六分。用于急性痹症且病灶较小者。
制针法：
《本草》记载马衔铁无毒。日华子说古旧的铁锭好，或者制作成医工用的针。按《本草》所述，桑木烧红的铁有毒。因此用火炼去毒性，因为火克金，能解铁毒，所以用来做针具的经过处理的铁备受推崇。又因“金”是金属的总称，铜铁皆属金类。
煮针法：
先将铁丝在火中烧红，截断，长度可为二寸或五寸，长短不拘。然后用蟾酥涂抹在针上，再次放入火中微烤，涂酥三次。到第三次时，趁热将针插入腊肉皮的内部（肉的外侧）。将以下药物先以水煎煮，待冷却后，取出针，在黄土中插百余下。

Method for Making Needles:
According to Materia Medica, iron from horse bits is non-toxic. Ri Hua Zi stated that old iron ingots are good, or they can be made into needles by medical artisans. According to Materia Medica, iron heated red-hot from mulberry wood is toxic. Therefore, fire is used to detoxify it, as Fire overcomes Metal, resolving the toxicity of iron. Thus, iron processed this way for making needles is highly valued. "Metal" is a general term for metals, including copper and iron.
Method for Boiling Needles:
First, heat an iron wire until red-hot in the fire, then cut it. Lengths can be 2 cun or 5 cun, no restriction on length. Next, coat the needle with Bufo Toxin (Chansu), and briefly reheat it in the fire. Apply Chansu coating three times. On the third application, while hot, insert the needle into the inner side of cured meat skin (outside the meat). Decoct the following herbs first:
Moschus (She Xiang, 5 fen)
Vitriolum Cupri et Ferri (Danfan, 1 qian)
Dendrobii Caulis (Shihu, 1 qian)
Manis Squama (Chuanshanjia, 3 qian)
Angelicae Sinensis Radix Recens Cauda (Guizhi Jiuchao, 3 qian, stir-fried with wine)
Cinnabaris (Zhusha, 3 qian)
Asari Radix (Xixin, 3 qian)
Curcumae Radix (Yujin, 3 qian)
Ligustici Chuanxiong Rhizoma (Chuanxiong, 3 qian)

Glycyrrhizae Radix et Rhizoma Node (Gancao Jie, 3 qian)
Aquilariae Lignum Resinatum (Chenxiang, 5 qian)
Magnetitum (Cishi, 1 liang).
