[source] crude mercurous chloride crystal.

[method] build a stove with brick, with 10 holes on it, and put a pan in each hole. First, put 3.5 Jin of gall alum and 3 jin of salt in the basin, add about 3 jin of water and 6.25 Jin of mercury to mix them into porridge, then add about 10 bowls of red earth to mix them into half dry and half wet soft clay, divide them into 10 parts and shape them into steamed bread. In addition, sprinkle a layer of sand in the center of the pan, put the steamed bread like objects on the sand, cover them with ceramic bowls or pots, and then seal them with mud to prevent gas leakage. Put it by the stove first. Each stove uses about 47 Jin of top-grade charcoal. First, burn it in full red outside the stove, then put it into each stove hole, burn it for a while, then put the fire on, put the center of the stove hole into an empty shape, if there is a fire, cover it with charcoal to avoid burning, then close the stove door and start to smolder. When the charcoal is completely burned and there is no flame and there is a layer of ash on the outside, place the sealed pan on each hole and close the door. 22 hours later, when the pot was boiling, most of the polygonal flake snow like crystals appeared in the pot. Sweep them down with chicken feathers, remove the impurities, and store them in a sealed dark place. Red soil and sand can still be used.

① Pinhuijingyao: "to make powder, we must first make it. The method of making it is to use one jin of soap alum, halve the salt, put the two flavors into the old iron pot, stir fry it with slow fire, still stir it with iron shovel, and fry it dry, like willow green.". The method of raising the powder is to set a platform, three feet high and two feet in diameter, not stick to bricks. A jin of jingchai charcoal is broken as big as a walnut, and burned on the platform. The powder is heated by fans. Each liter of powder is made of one or two coins of mercury. The stone mortar is placed inside, and the stone pestle is grinded. The mercury star is not seen. However, two coins of coarse alum are put in. The three flavors are mixed well, and the center of the iron bowl is spread evenly. The thickness is about one-third, Cover the Chengjiang tile basin with salt mud. Don't make it too solid. In fact, it's hard to get up. When the fire is over and the basin is warm, gently wipe the seam and basin with hands dipped in water. Use bricks to stand under the basin to protect the fire. When the fire is over and the basin is warm, uncover it. Do not let the hands be heavy. If it is heavy, it will vibrate down. The powder coagulates on the bottom of the basin, which looks like a snowflake. Sweep it with feathers and store the porcelain. The sediment in the basin is turbid, and the material rises again. "

② "Ascending and refining light powder method: use one or two pairs of mercury, two pairs of alum, and one or two pairs of salt. After the same research, you can't see the stars. Spread it in the iron ware, cover it with a small black basin, sift the stove ash and salt water, seal the mouth of the basin, beat the two sticks of incense with charcoal, take it out, and the powder will rise on the basin. Its white as snow, light and lovely. One or two mercury can make eight yuan. "

[medicinal material] is flake crystal, which looks like snowflake. It is white with silver luster. It is light and easy to break into white powder when twisted by hand. White, large, bright, needle like crystal, light and anhydrous silver beads are preferred. Insoluble in water and acid, put on the iron heating, then gradually turn yellow, and finally into smoke, leaving no traces. When potassium hydroxide solution is added, black Mercurous Oxide is precipitated, and when ammonia water is added to shake it, it turns black.

Produced in Hubei, Hebei, Hunan, Yunnan and other places.

[chemical composition] it mainly contains mercurous chloride. The natural product is Mingjiao mercury mine, but it is usually prepared artificially. It is tasteless and colorless (usually with light yellow) flake crystal. Its dry product contains no less than 99.6% HgCl. Although the toxicity of this product is small, when it is boiled with water, it will decompose into mercuric chloride and metallic mercury, both of which are highly toxic. When exposed to light, the color of calomel gradually darkens, which is also highly toxic due to the same change.

[pharmacological action] light powder has bactericidal effect for external use, and can prevent abnormal intestinal fermentation and facilitate defecation when taken in appropriate amount. After oral administration of calomel, a small part of it becomes soluble divalent mercury ion when it meets with alkali and bile in the intestine. Divalent mercury ion can inhibit the metabolism and functional activities of intestinal wall cells, hinder the absorption of electrolytes and water in the intestine and lead to diarrhea; it can also inhibit the bacteria in the intestine from turning biliverdin into bilirubin, and affect the transformation of biliverdin due to the rapid discharge of intestinal contents, so the stool can turn green after taking medicine. After absorption of divalent mercury ion, it can also combine with sulfhydryl enzyme in renal tubular cells, inhibit the activity of enzyme, affect its resorption function and have diuretic effect. Large quantities can cause poisoning. The median lethal dose of the suspension was 410 mg / kg in mice and 1740 mg / kg in rats. After poisoning, the heart, liver and kidney of the mice all had different degrees of pathological changes. The epithelial cells of renal tubules were the most significant, with turbid swelling, lipid degeneration, necrosis, etc. some large follicles in the ovary were broken, and there were leukocyte infiltration. The light powder water extract (1:3) could inhibit Trichophyton violaceum, Xanthomonas schrenkiani, Microcystis auduensis, Epidermophyton rubrum, Nocardia stellata and other skin fungi in vitro.
