In the twelfth lunar month, collect the gallbladder of the black carp (Siniperca chuatsi), dry it in the shade. Alternatively, store it in a human bladder and dry it, then grind for use.
Select clean and white Juncus effusus (Jiedaca, 灯心草), place it on a gold-lacquered table, spray with clear water onto the Juncus effusus. Use one end of a brush tube to block the opening, insert the Juncus effusus into the tube using bamboo chopsticks, and seal the other end with paper. Place one end in the fire, burn until the bamboo tube turns red, then remove. Place it in a bottle, cover with a wet towel, wait for it to cool, then remove, discard the bamboo ash, and store for future use. The best quality is black and forms a compact mass.
Take one tael of the inner meat of Crotonis Fructus (Badou, 巴豆) after removing the husk. Add seven qian of Sesamum indicum oil (Mahu, 麻油) and seven qian of wine, decoct together until the oil and wine are completely evaporated. Remove and place into Mingfan (Alumen, 明矾). Put into a silver pot, heat over charcoal fire. Insert chopsticks into the bottom of the pot and stir until no lumps remain. Cover the pot upside down on a clean surface, then cover with a bowl. After seven days, collect and store for use.
Another method: Take three qian of Alumen (Mingfan, 明矾), melt it in a yin vessel, throw in three kernels of Crotonis Fructus (Badou, 巴豆). Wait until dry, remove the Crotonis Fructus, grind for use. This is named "Ba Fan".
In the fourth lunar month, buy green plums, crush them, remove the pits, and place them in a bowl. Layer with Alumen (Mingfan, 明矾). Catch Agriolimax agrestis (Yanyou, 蜒蚰/蛞蝓), the quantity is not restricted. Wait until the Alumen and Agriolimax agrestis are completely dissolved. Then add another layer of crushed plum and Alumen. Catch more Agriolimax agrestis and add them, until completely dissolved. After one hundred days, pour into a silver pot, heat over charcoal fire. Insert chopsticks into the bottom of the pot and stir until no lumps remain. When it rises like a steamed bun, remove immediately. Cover the pot upside down on the ground, cover with a bowl. After seven days, the fire toxicity is completely expelled. Collect and store for use.
Another method: Take large, crisp green plums, remove the pits, and crush them. Spread them at the bottom of a bowl. Place several Agriolimax agrestis (Yanyou, 蜒蚰/蛞蝓) on top of the plum flesh. Then spread powdered Alumen (Bai Fan, 白矾) on top of the Agriolimax agrestis. Continue layering until finished. Wait until the Alumen and Agriolimax agrestis are completely dissolved. Dry the plums thoroughly in the sun, then grind for use. Alternatively, roast them on tiles until crisp and grind into powder. For conditions such as phlegm-fluid obstruction causing throat wind (Houfeng, 喉风), add this to various insufflation powders; all are effective. Or mix with honey water and administer to penetrate the throat; it can also resolve phlegm with miraculous efficacy.
First, put powdered Platycladi Semen (Cebai Zi, 侧柏子) into a porcelain pot. Then add Succinum (Hupo, 琥珀) into the powder. Boil over charcoal fire from Si hour (9-11 AM) to Shen hour (3-5 PM). When a unique light appears, remove it. Lift it so it falls like heavy powder, and grind until extremely fine.
