Saltpeter, sulfur, realgar, orpiment, arsenic, etalite, etc., are all genus of gold and stone, each with unique chemical properties.
Saltpeter, the main component is potassium nitrate. Its cold and oxidizing. In case of flammable substances, it can help ignite and ignite, and is often used in ancient fire attack techniques and alchemy. In fire, it can react violently with many substances, causing combustion and even explosion.
Sulfur, warm in nature, sour in taste, flammable. When burned, sulfur dioxide gas is generated, which has a pungent odor. In chemical reactions, it can be used as both an oxidizer and a reducing agent. When heated with metals, it can combine to form metal sulfides.
Realgar, mainly containing arsenic disulfide. The temperature is toxic, and it can be decomposed after heating, releasing toxic substances such as arsenic. Its red yellow color is often used for alchemy in ancient times, and it is also used to exorcise insects and evil spirits.
Orpiment, the main component is arsenic trisulfide, and the color is yellow like gold. Similar to realgar, it is also toxic. In chemical reactions, arsenic's characteristics make it participate in many complex reactions, and it can change differently from acids and bases.
Arsenic is arsenic trioxide, a highly toxic substance. Although it is highly toxic, it can react with a variety of reducing agents and be reduced to arsenic elementals or low-priced arsenic compounds.
Alumite, a wide variety, such as alum (potassium aluminum sulfate crystal). It is acidic in nature, soluble in water, and hydrolyzed to make the solution acidic. It is used in many processes such as water purification and tanning, and can decompose with metal ions to form precipitation.
The chemical properties of these substances have far-reaching effects and applications in ancient alchemy, medicine, technology and many other fields. It not only left precious experience and inspiration for the ancient people to explore nature and use the fruits of nature, but also left precious experience and inspiration for the development of chemistry in later generations.

Borax is sweet, salty, cold in nature, and has the ability to clear away heat, detoxify, reduce swelling and prevent corrosion. Its physical properties are quite unique. Borax is usually colorless translucent crystals or white crystalline powder, which is its appearance. Its texture is relatively soft, with a Mohs hardness of about 2-2.5, just like the softness of a light cloud, and it feels delicate to the touch.
Borax is soluble in water, but its solubility varies with temperature. At room temperature, the solubility is moderate, but when the temperature increases, the amount of its dissolution in water increases, just like when spring snow meets the warm sun, it gradually melts in water. And the aqueous solution of borax is weakly alkaline, which makes it unique in many fields.
Furthermore, the density of borax is about 1.73 g/cm3. Compared with common things, the density is not high, but it also has its own specific weight. Its melting point is about 743 ° C. When the temperature rises to such a height, borax disappears into fire like ice and turns into a liquid state, showing a change in material form.
Poria, on the other hand, is sweet, light, and flat in nature. Poria is the dry sclerotia of Poria, a polyporous fungus, with a spherical, oval, or irregular appearance. The outer skin is thin and rough, tan to dark brown, with obvious wrinkled texture. Its texture is solid, and the section is grainy, some with cracks, the outer layer is light brown, the inner white, and a few light red. Poria cocos are insoluble in water, with a relative density of about 1.2-1.3. The hardness is small, and the nails can be scratched and left marks.
As for gypsum, it tastes refreshing, sweet, and has a cold nature. The main component of gypsum is water-containing calcium sulfate, which is often a fibrous aggregate, or lumpy or granular. Those who are pure are colorless and transparent, and appear white, gray, yellow and other colors due to impurities. Its texture is soft, the Mohs hardness is about 2, and the nails can easily scratch marks. Gypsum is slightly soluble in water, heated to 128 ° C, loses part of the crystalline water and matures gypsum. At this time, the shape and properties are changed, and it can be used to shape models, etc. Its density is about 2.32 grams/cubic centimeter.

The method of preparing rhino horn and antelope brain ointment, Poria cocos ointment, and dew ointment is an ancient and exquisite skill that cannot be ignored today.
To make rhino horn and antelope brain ointment, you need to get rhino horn and antelope horn, both of which are rare things and should be used with awe. First grind rhino horn and antelope horn finely, such as the method of grinding ink, to make it into a very fine powder. Prepare the first-class honey, boil it slowly over low heat, until the honey color darkens, and even small bubbles appear. Slowly pour in the ground horn powder, stirring while inverting, so that the two are fully integrated. Then simmer for a while on a gentle fire, stirring constantly during this period to prevent burnt paste. When it is moderately thick, pour it into a clean porcelain urn, seal it in a cool place, and the paste is ready.
To make Poria cocos paste, choose the best Poria cocos, soak them in water after washing, about two hours, so that the Poria cocos are full of water. Then put them in a cage drawer and steam them, take them out and let them cool, and mash them into a mud. Take another glutinous rice, wash them, and cook them into porridge. When the porridge is slightly cool, mix the Poria cocos mud with the porridge, add an appropriate amount of sugar to taste, and stir well. Then pour this mixture into the mold, put them in the refrigerator and refrigerate them. When they solidify, the Poria cocos paste will be done.
To make dew paste, choose tender and pest-free flowers and leaves, such as osmanthus, roses, etc. Place the flowers and leaves in a still, add an appropriate amount of water, and distill over low heat. The water vapor rises, cools through a condenser, and the dripping liquid is flower dew. Collect the flower dew, add an appropriate amount of rock sugar, stir until dissolved, and then boil it slowly over low heat to remove some moisture, make the dew thicker, put it in a bottle, and the dew paste will be prepared.
These three preparation methods require careful attention. From material selection to production, step by step is rigorous to obtain exquisite ointments.

The fragrance of musk deer is sought by the world, but when using it, there are several things to pay attention to.
First, musk deer is a rare thing, and its fragrance is not easy to come by. Musk deer are cunning, often living in the depths of mountains and forests, and it is not easy to catch. And today, most of the musk deer are conservation animals, and it is illegal to hunt, kill, eat, and trade wild animals and their products. Therefore, the fragrance of musk deer should be used with caution. It is not urgent and should not be used lightly, so as not to violate the law and protect the reproduction of this rare species.
Second, the medicinal power of musk is fierce. Although it can pass through all orifices, open meridians and collaterals, and penetrate muscles and bones, it has a good effect on symptoms such as fainting, swelling and poisoning of sores, sputum nucleus, throat swelling and pain. However, if its sex runs away, it is easy to consume qi and injure yin. If a person with weak righteousness in the body misuses or overuses musk, it may cause the deficiency of righteousness and the disease to recur. If a woman is pregnant, she should especially avoid it. Cover musk has the disadvantages of abortion, which can cause fetal restlessness, and even miscarriage, endangering the safety of pregnant women and fetuses.
Third, when using musk, it should be clear how it is processed. Proper processing can maximize its medicinal effect and reduce its toxicity. Musk is mostly taken at the end of the grind or in pills or powders. It should not be fried in decoctions for a long time. Due to high temperature, it is easy to evaporate the active ingredients in musk, resulting in a great reduction in the efficacy of the medicine. And the storage of musk is also exquisite. It should be sealed in a dry and cool place to prevent its aroma from being lost.
Fourth, use musk to treat diseases, and follow the doctor's advice. Doctors need to verify and seek the cause and weigh the pros and cons. Patients should not abuse musk on their own to avoid mistreatment. In case of difficult diseases, they must carefully investigate the condition and match other medicines appropriately, so that the use of musk can not only achieve the purpose of removing diseases, but also not be too dangerous.
In short, although musk is a good medicine, when using it, you need to pay more attention to protecting the species, your own physical condition, processing and storage, and following the doctor's instructions in order to obtain its benefits and avoid its harm.
