A few days ago, I got together with my hair and found that she had some cold symptoms, so I took the opportunity to feel my pulse. Just as I was taking my pulse carefully, she suddenly said, "My father bought me some donkey-hide gelatin recently. Can I eat? " Thinking that she has caught a cold recently, she is afraid of being locked up before the evil comes out, so naturally she doesn't eat Ejiao. She added, "My father spent a lot of money on it. A kilo is more than 1000. Don't you want to eat? " I was surprised: "How much did your father buy for you?" She smiled "just half a catty, hehe". I was relieved to hear that I only bought half a catty, because I generally liked sports when I was young. I am tall and thin, and my body mass index is completely within the normal range. I am a very healthy and beautiful girl with rosy complexion and smooth skin. Where do you need Ejiao to replenish your body? If her father buys a few kilograms, I don't know how many years it will take to finish.

So I told her about "Ejiao two or three things".

The first is about the blood-enriching effect of Ejiao. This effect was recognized by people after the Tang and Song Dynasties. The Classic of Materia Medica says "nourishing liver and blood", and Li Shizhen even said in Compendium of Materia Medica that "the most important thing is to replenish blood and promote fluid production". Before the Tang and Song Dynasties, Ejiao only thought it could nourish yin and even replenish qi, but did not directly mention the role of enriching blood.

Pharmacological research shows that the glue stick made from the skin of Equus donkey is mainly composed of collagen and its hydrolyzed amino acids, which can enhance the hematopoietic function of bone marrow and provide a material basis for the production of blood cells, so it has a good blood-enriching effect. Because Ejiao can enhance the hematopoietic function of bone marrow and increase the content of platelets with coagulation function in human body, Ejiao can replenish blood and stop bleeding.

Secondly, Ejiao runs through the ancient and modern functions in people's understanding-nourishing yin and moistening dryness. The famous doctor's Bielu is mainly due to "fatigue and thinness, yin deficiency", which can be used for various yin deficiency syndromes, such as liver, lung, heart yin deficiency or yin-blood deficiency. However, the ancient herbal medicine emphasized that Ejiao had a significant effect on lung deficiency. Yang Shiying said that Ejiao is an essential medicine for lung meridian because of its flat nature, and Herbal Medicine in Decoction also said that "lung deficiency is extremely damaging, and Ejiao is not supplemented when coughing and purulent discharge occur". In these cases, lung deficiency is due to yin fluid or even yin blood. Therefore, Chinese medicine textbooks often call it "nourishing yin and moistening dryness" when summarizing the efficacy of Ejiao.

Ejiao has a high health status in modern times, and it is a kind of flesh-and-blood product. The production process is time-consuming and laborious, and the people like it very much. However, Ejiao is not suitable for everyone, nor for every stage. For example, the general parturient, patients with long-term illness and physical weakness, and patients recovering after operation take it regularly and quantitatively under the guidance of doctors, and the effect is very good.

However, Ejiao is greasy in nature. For people with weak spleen and stomach and indigestion, taking it alone is simply a heavy hammer. Spleen and stomach can't effectively exert their transport ability, and the donkey-hide gelatin eaten can't be absorbed by the body for its own use, which is a great burden to the body.

Then the spleen and stomach are weak, and the biochemistry of qi and blood is not good, but people with blood deficiency can't eat Ejiao? Ejiao is an essential drug for enriching blood, and the effect of enriching blood is not comparable to that of ordinary herbs. If the blood deficiency is obvious, it can be taken even if the spleen and stomach are weak as long as the compatibility is proper. Huangqi is one of the golden partners. Colla Corii Asini nourishes blood, and Radix Astragali nourishes qi. What are their health benefits when they are together? Many people don't know. Astragalus is good at invigorating the qi of the spleen and stomach. "Rihuazi Materia Medica" contains "Astragalus can help strengthen muscles and bones, grow meat and replenish blood". Add Ejiao to create a "flesh".

But the qi of Astragalus membranaceus is also stagnant. If astragalus and donkey-hide gelatin are soaked in water together, the dosage should not be too large. Astragalus membranaceus 10- 15g and Ejiao 1-3g are more suitable, so it is more effective to give the spleen and stomach time to adapt. Nowadays, Ejiao is generally fried with maltose to improve the taste and efficacy. When soaking with astragalus, it is better to put some tangerine peel.
