Why is donkey skin made of ejiao, but not the skin of other animals?

Ejiao is a solid animal glue that is concentrated in donkey skin, and its main component is protein, which has high medicinal value.

The main ingredient of Ejiao is protein, but the main ingredient of other animals is also protein, and it stands to reason that they can all make Ejiao, but why can only donkey skin make it?

In fact, Ejiao has a history of more than 2,000 years, the earliest recorded in the "Shennong Materia Medica", is a first-class medicinal material, with many ancient records, Ejiao in ancient times the raw materials are also made of cowhide, donkey skin and other animal skins, but due to continuous improvement and improvement, people gradually found that the original donkey skin to make Ejiao medicinal value is better, so they switched to donkey skin, has been used to this day.

That is to say, the skin of other animals is not that it cannot be made into ejiao, but the ejiao made is not as good as donkey skin in terms of efficacy, and even some animal skins are harmful to the body of pregnant women or the elderly because of some other trace elements contained in them, so over time, people no longer use the skins of other animals, but have been using donkey skins to make ejiao.

There are many benefits of eating Ejiao, Ejiao is the top grade of blood nourishment, and has the effect of nourishing yin and moisturizing irritability, and it also has an improving effect on the growth and development of children and teenagers.

In addition, the Ejiao products on the market are uneven, and there are great differences in efficacy, and there are even some black-hearted manufacturers who make harmful Ejiao.

You can go to find information by yourself or find a professional to consult, traditional Chinese medicine pays attention to the place of origin, so you must choose the brand when buying.

Actually, I used to have this confusion too. At first, I thought that Ejiao was a kind of green plant that refers to traditional Chinese medicine that blindly regulates qi and blood. Later, it became known that he was a gelatinous drug.

By chance, I heard the elders discussing the resale of all kinds of skins, especially donkey skins, which are very expensive, and a good quality donkey skin can be sold for a very high price, so I asked why, and the elders told me that donkey skin is Ejiao, which can regulate qi and blood, and can also maintain beauty, which is very precious. I always thought that Ejiao was a donkey's skin, and I thought this thing was very strange. After slowly getting in touch with more pharmacological knowledge, I realized that Ejiao is made from donkey skin.

So, why donkey skins instead of horse skins and pig skins? Because, in the eyes of the ancients, the horse has a fierce temperament, belongs to the fire nature, and like other animals, if you whip him, it can run and run happily until death. And the donkey is different, the more you beat it, the more it stands there motionless, beats it to death, it is still that virtuous, as the saying goes, you are stubborn donkey stubborn, that's what it means.

Therefore, donkeys are water-based. Modern people regard Ejiao as a good medicine for blood tonic, in fact, to enhance the astringent function of blood through its medicinal properties. Therefore, the water-based donkey skin is selected to be boiled.

There is also a legend about donkey skin being used as ejiao. Chun said that the Empress Dowager Cixi was pregnant with a fetus. There are signs of miscarriage, many famous doctors are helpless, and later there is a country doctor, who used donkey skin to boil medicinal materials, that is, the later Ejiao gave, she **.

The fetus was also saved, and this fetus was the later Tongzhi Emperor. Since then, Ejiao has become popular as a good product for blood replenishment and qi management.

According to the clear provisions of the National Pharmacopoeia, Ejiao can only be boiled with donkey skin, which has the effect of nourishing blood and nourishing yin and moisturizing dryness. The effect of other animal fur boiling gum is different, among which the cowhide boiling gum is called yellow gelatin, its function is similar to Ejiao but the effect is secondary, and the effect of Ejiao boiled with horse skin is just the opposite, horse skin medicinal blood, once the pregnant woman eats it, it is very likely to lead to miscarriage. If it is made of ejiao made from other animal skins, this is a counterfeit product.

In addition, in the process of consuming pure ejiao, it is necessary to pay attention to the amount not to be too large, 3 to 9 grams per person per day, in addition, do not eat when you have a cold, diarrhea, and indigestion. If you need to buy Ejiao, it is recommended to buy Ejiao from Shandong Dong'e Ejiao and Beijing Tongrentang, which is more formal and reliable.

As we all know, Ejiao is a good product for nourishing yin and blood, and has a good effect on qi and blood, dizziness, palpitations, dry cough and other symptoms. However, most of the ejiao we commonly see every day is made from donkey skin. So why does Ejiao be made of donkey skin, but not other animal skins?

It's complete nonsense, Ejiao is just a trick to cheat money and deceive people, just look at how much donkey skin you buy for 2,000 yuan. The result will be the same as Cordyceps.

Originally, it was boiled with cowhide and horses. But the effect is not as good as donkey skin.

Before the Eastern Han Dynasty, when the "Shennong Materia Medica" was written, it did not specifically refer to what kind of skin should be used to "make glue", horse skin, cow skin, pig skin, donkey skin, and all kinds of animal skins. The method is to remove the hair of the animal, boil the skin, boil it into a thick soup, and then pour it into a utensil to cool, slice it, and dry it.

Tao Hongjing, a famous doctor of the Liang Dynasty, pointed out in his "Catalogue of Famous Doctors" that this animal skin should be cowhide, and "Dong'e" produced the best. Jia Sixian, an agronomist of the Northern Wei Dynasty, further pointed out in his historical masterpiece "Qi Min Yaoshu" that the production of ejiao is based on cowhide: sand cowhide, buffalo skin, pig skin, donkey, horse, camel, and mule skin are secondary.

The use of donkey skin instead of cowhide should have started with the ban on cattle in the late Tang and early Song dynasties, when cattle existed as a strategic material.

The difference between pig skin ejiao and donkey skin ejiao:First, the role of the two is different:

1. The effect of Ejiao (also known as donkey skin glue): Ejiao has the effect of increasing red blood cells and hemoglobin, which can promote hematopoietic function; It can increase white blood cells, platelets and increase blood oxygen levels.

2. The role of pigskin: it has an important physiological health care effect on people's tendons, bones and hair.

Second, the composition of the two is different:

1. Ingredients of Ejiao: Ejiao contains 27 kinds of elements such as gelatin, bone collagen, peptides, proteins, sulfate, biological acids and metal calcium, potassium, sodium, magnesium, zinc, iron, copper, manganese, etc., and proteolysis produces more than 18 kinds of amino acids, such as lysine, histidine, arginine, aspartic acid, threonine, serine, glutamic acid, glycine, leucine and other amino acids.

2. Composition of pig skin: Pig skin is rich in protein, carbohydrates and a small amount of fat.

3. The precautions for the two are different:

1. Precautions for Ejiao: Those with weak spleen and stomach should take it with caution.

2. Precautions for pig skin: When cooking pig skin, you must first clean the hair on the pig skin, otherwise eating pig hair is harmful to health.

Ejiao is made from donkey skin.

The record of Ejiao as a medicine can be traced back to the "Shennong's Materia Medica". The main raw material used in ancient Ejiao was originally cowhide, and it was clearly pointed out in the "Famous Doctor's Record" of the Northern and Southern Dynasties: "Ejiao, born in Dongping County, made of cowhide, out of Dong'e."

In the Tang Dynasty, it was recorded in the Tang Dynasty's "Qianjinfang Food Treatment" that cowhide, horse skin, and donkey skin were all used to make ejiao, indicating that the raw materials of ejiao were gradually diversified.

In the Five Dynasties and the Song Dynasty, cowhide was mainly used for armaments, such as armor, bows and crossbows, etc., which were not enough, so the "ban on cowhide" was promulgated, and the people were not allowed to hide cowhide. This practice is similar to the official camp order of salt and iron and the ban on ginseng mining in Chinese history. Due to the limitation of resources, cowhide gradually withdrew from the market, and donkey skin became a substitute for making ejiao.

In ancient times, donkeys could not charge on the battlefield like horses, nor could they drive in the fields like oxen. As commented in the Han Dynasty's "Treatise on Salt and Iron": Winning a donkey is not the power of cattle and horses.

The little donkey is often unloaded after the end of the mission of pulling the sleeve and grinding. In order to exert the residual heat, donkey skin came in handy in the production of ejiao.

Ejiao's Now:

Ejiao made from cowhide is called yellow gelatin, while those made from donkey skin are called ejiao.

Nowadays, donkey skin has become the mainstream of Ejiao raw materials, and the Chinese Pharmacopoeia has also determined the legal status of donkey skin as a raw material for Ejiao.

The shape of Ejiao is rectangular blocks, the color is brownish-black or jet-black, and it is accompanied by luster, showing a slightly transparent effect under light.

And according to the clear provisions of the National Pharmacopoeia, when making ejiao, only donkey skin can be used to boil, and the effect of the glue boiled out of the fur of other animals in the eggplant section is different, among which if the horse skin is used to boil ejiao, it will lead to miscarriage of pregnant women.

Ejiao is made from the skin of a donkey.

Ejiao, the name of traditional Chinese medicine. It is a rubber block made of the skin of the donkey of the equine donkey genus, which is boiled after bleaching and removing hair, which is a traditional nourishing and nourishing blood product. Donkey skins can be harvested all year round.

Generally, the production season is from October to May of the following year. First, put the donkey branch skin into a container, soak it in water to soften it, remove the donkey hair, chop it into small pieces, then soak it in water to make it white, put it in boiling water, take it out when the skin is curled, and then put it into a boiling pot for boiling. After boiling, pour it into a container, take it out after the gel has solidified, cut it into small pieces, and let it dry.

This product comes in neat rectangular or square blocks. Usually about length, width, thickness or . The surface is tan or black-brown, and it is shiny.
