1. What is diamond powder?
Among the works of many martial arts novelists such as Gu Long and Wen Rui'an, Sichuan Tangmen, located in the Daba Mountain in Chongqing, is good at using emery as a hidden weapon poison.
In modern times, diamond micropowder usually refers to diamond particles with a fineness of 36/54 micron, which is divided into single crystal diamond micropowder and polycrystalline diamond micropowder.
The single crystal diamond micropowder is made of synthetic diamond single crystal abrasive grains, which are pulverized and shaped, and are produced by a special process of superhard materials. Diamond micropowder has high hardness and good wear resistance and can be widely used in cutting, grinding, drilling and polishing. It is an ideal raw material for grinding and polishing high hardness materials such as cemented carbide, ceramics, gemstones and optical glass.
The polycrystalline diamond micropowder is made by using graphite as a raw material by a unique blasting method. The shock wave of the directional blasting of the high explosive explosive causes the metal flyer to accelerate and hit the graphite sheet, thereby causing the graphite to be converted into polycrystalline diamond. Its structure is very similar to natural diamond, it is formed by the combination of unsaturated bonds and has good toughness.
Second, why is diamond micropowder a chronic poison?
According to legend, in the 16th and 17th centuries, the romantic French led the diamond trend. The necklace of the French king Ferran I was set with 11 large diamonds. In addition to his love of jewelry, his queen Catherine also mixed the powder into the food to poison the political opponents. The "pick powder" that has been passed down in European history may be diamond powder.
Due to the high hardness of diamond, it can not be digested and absorbed by the gastrointestinal tract after entering the digestive system. At the same time, due to the powder and easy adhesion to the gastrointestinal wall, the gastrointestinal tract peristalsis causes the diamond powder and the gastrointestinal tract to rub into the digestive tract chronic bleeding. It can be a chronic poison that is difficult to be watched by, such as perforation of the digestive tract and ulceration of the digestive tract. 
Stills of "Female Doctor Alum" (the emperor vomits blood by eating diamond micropowder)
In the TV series, female doctors have found some ways to detoxify according to folk remedies. As mentioned in the play, adding a little wood chips to the noodle soup can alleviate the symptoms. Moreover, the hydrophobic and lipophilic properties of the diamond micropowder can be utilized, and the eucalyptus oil is used to help the diamond diamond to be excluded from the body.

Using the hydrophobic and lipophilic properties of diamond powder, the use of sesame oil is also mentioned.
Fourth, from the harm to the rescue of nano-scale diamond micro-powder in the medical field
With the development and development of diamond micropowder production technology and application fields, nano-scale diamond micro-powder has now become a "good medicine" for treating diseases in modern medicine.
According to the reporter of China Superhard Materials Network, the nano-diamond powder produced by Jiangsu Jinhaifeng can be applied to cell separation and cell staining in medical treatment; and the high-performance bone-like bio-engineering material experiment was established in Hunan on April 1, 2016. Room, nano-diamond film has become an important research direction.
British researchers have also used a common industrial nano-diamond to invent a new microscopic imaging technique for detecting live cells. Researchers believe the technology can effectively improve the effectiveness of medical research and treatment. Due to its low toxicity characteristics, nanodiamonds have extremely high medical imaging contrast agents and development prospects for drug delivery devices.
According to a research report from the University of Bremen in Germany, nanodiamonds can effectively kill bacteria like metal silver and copper, and kill bacteria in a short time.
Researchers at the University of California invented a new drug delivery system that embeds nanodiamonds into contact lenses to deliver drugs to treat glaucoma. The researchers combined the drug with nanodiamond, and when the drug comes into contact with lysozyme in the tears, it is released and acts on the eye. Researchers say the treatment is good for drug delivery, and diamonds make contact lenses more durable in delivering drugs.
With the continuous development of diamond micropowder application technology, diamond micropowder, once used as a chronic poison, will become a good medicine to save people in the future.

Some time ago, the "Women's Doctors of the Ming Dynasty", which was broadcast by major TV stations, I believe many people have seen it. In the plot, although the Ming dynasty Zhu Xi won the throne, he was sent to his wife, Wang Huang, and lost his hand to poison. And this deadly poison is actually a colorless and odorless chronic poison-diamond powder.
