空青是点眼治疗眼疾的神药，天然生成的极难得到，现在采用人工种植的方法，其疗效与天然生成的没有差别。配方如下：
朴硝半钱，白蒺藜、龙胆草各一分，仙灵脾叶、旋复花各一钱。
将上述药物共同研磨成粉末，取一块拳头大小的黄泥，与药物混合均匀，加水调得像软饭一样稠度，做成土饼。取五枚太平通宝铜钱，按照东、南、西、北、中五个方位排列好，在铜钱的光面上分别刻上金、木、水、火、土五个字，刻字的一面朝下，有字的一面（钱文）朝上，依五行方位安放妥当。取像豆子大小的砂粒，每枚铜钱上放置四块，置于那五个字的孔隙之中，必须放置在干燥的黄土之上，顺着土饼的纹理，上面覆盖一个新的砂盆，再将干燥的黄土覆盖在砂盆上。冬天十天，夏天五天，取出。从铜钱上取下这些物质，细细研磨后入药，火候不可过老，也不可太嫩，必须适中。
本品能够强壮阴气、补益阳气，疏通全身关节，通畅九窍，补益虚损劳伤，促进乳汁分泌，服用后使人阳气突然充沛，饮食量加倍增加，身体形态变得壮实强健。选择原料时不论浓淡厚薄，只要颜色明亮洁净且有光泽的，就可以用来炼制。只有黄色和赤色的不适合使用。炼制时将一斤原料放入金银器皿中，然后将大锅放置于乳器之中，使乳器没入水中，煮沸时保持像鱼眼睛冒泡那样的沸腾状态，水分减少就随时添加。如果是稀薄的钟乳粉，煮三天三夜；如果是雁齿状或浓肥的钟乳管，煮七天七夜。等到钟乳粉的颜色变成黄白色，就说明炼好了，如果怀疑没熟透可以继续煮，总共煮满十天左右为佳。煮完后从金银器皿中取出，大锅内的水变得浑浊发黄，要倒掉，不要让人服用。再加入清水重新放入上面的乳器中，煮大约半天时间，取出，此时水仍然清澈，如果不发生变色就停止，这样钟乳粉就没有毒性了。
Select large-sized *Fuzi* (Prepared Aconite Root, *Aconiti Lateralis Radix Praeparata*), soak them in urine from an uncircumcised boy to a depth of three cun. Change the urine daily, soaking for three months in summer and five months in winter. Then change to fresh urine again, and boil until the "two fragrances" (referring to specific aromatic compounds or stages of processing) are exhausted.
Remove the skin and umbilical scar, thread them with string, and dry in the shade, or sun-dry is also acceptable. Store for future use.
*Kongqing* (Azurite, *Cupri Carbonas*) is a divine medicine for eye drops. Naturally occurring ones are extremely difficult to obtain; now they can be artificially cultivated, and their efficacy is no different from natural ones. The prescription is as follows:
*Bopiao* (Mirabilite, *Natrii Sulfas*) half qian, *Bajili* (Tribulus Fruit, *Tribuli Fructus*) and *Longdancao* (Gentian Root, *Gentianae Radix*) each one fen, *Xianlingpi Ye* (Epimedium Leaf, *Epimedii Folium*) and *Xuanjinhua* (Inula Flower, *Inulae Flos*) each one qian.
Grind all ingredients into powder. Take a piece of yellow mud the size of a fist, mix evenly with the medicine, add water to adjust the consistency like soft rice, and form into earthen cakes. Use five Taiping Tongbao copper coins, arrange them according to the Five Directions (East, South, West, North, Center). On the smooth side of the coins, inscribe the characters Gold, Wood, Water, Fire, and Earth. Place the coins with the inscribed side down and the coin face up, arranged according to the Five Directions. Place sand grains the size of beans, four pieces per coin, into the gaps of the five characters. This must be placed on dry yellow earth, aligned with the earthen cake. Cover with a new clay pot, then cover the pot with dry yellow earth. In winter, process for ten days; in summer, for five days. Remove and harvest from the coins. Grind finely for medicinal use. The processing must not be too old (over-processed) nor too tender (under-processed), but must be just right.

Taking it causes a sudden surge of Yang Qi, doubles food intake, and makes the physique robust and vigorous. For selection, regardless of thickness, only those with bright, clean, and lustrous color are suitable for refining. Those with yellow or red colors are unsuitable. During refining, place one jin of the material in a gold or silver vessel. Place this vessel inside a large cauldron filled with water, ensuring the vessel is submerged. Boil maintaining a gentle simmer like fish eyes bubbling, adding water as it evaporates. If the material is thin powder, boil for three days and nights; if it is雁齿 (goose-tooth shaped) or thick/fatty stalactites, boil for seven days and nights. Wait until the color turns yellowish-white, indicating it is ready. If unsure if it is raw, continue boiling; ten days total is ideal. After boiling, remove from the gold/silver vessel. The water in the cauldron will become yellow and turbid; discard it, do not let anyone consume it. Add clear water back into the inner vessel, boil for about half a day, then remove. The water should remain clear; if it does not change color, stop. The stalactite is now non-toxic.
