Liu Yiyan praised: "The value of amber itself is very high, not only for simple decoration, wearing amber can calm the nerves, calm the mood of anxiety, can reduce noise and remove the heart fire, relax the spirit, relieve stress, let people always be in a peaceful state, with the effect of calming the nerves, cooling the blood, can effectively improve the blood circulation of the human body, especially for the weakness of qi and blood, anemia and other blood problems, but also help to improve sleep and maintain the stability of the endocrine, in addition, it is also a traditional Chinese medicine." ”

"Chinese medicine?"

Yang Hao was surprised.

This amber looks like resin, how can it also be used as a traditional Chinese medicine?

But that sounds like a great thing!

"Yes!"

Liu Yiyan said: "Amber is a hydrocarbon formed by the condensation of the resin of the ancient pine plant buried in the ground for a long time, which can be said to be the fossil of pine resin in ancient times, which has the effect of calming and calming the nerves, invigorating blood and dissipating stasis, and diluting water, and can effectively solve the problems of insomnia and dreams, weakness of limbs, and loss of appetite. ”

"Master Liu is right!"

Chen Song continued: "The Compendium of Materia Medica has a record of it, and the name of amber is Jiangzhu, which has a sweet, flat, non-toxic smell, and is mainly used to calm the heart and eyes, stop bleeding and build muscles, carbuncle sores and poison, and also have a certain effect on bruises and wounds. It is also said in the record that it can calm the five organs, calm the soul, cool the lungs and clear the liver, abrasion obstacles, stop palpitations and insomnia, apply boils and pull out poison, quench thirst and remove annoyance, eliminate blood congestion, and also have curative effects on five kinds of gonorrhea. It is also mentioned in the Materia Medica that it can strengthen the heart, sharpen the eyes, stop heartache, madness, break knots, and have the effect of clearing the lungs!"

"How can it be so powerful?!"

Yang Hao exclaimed in surprise.

Can this still be considered medicine?

It's almost omnipotent!

Liu Yiyan smiled: "The reason why amber has such an effect is related to the composition of amber, amber is composed of resin and volatile oil, in the process of formation, it will experience volcanic eruptions, crustal changes and other environmental impacts, so that amber contains a large number of amino acids and mineral elements beneficial to the human body, these ingredients make amber have beauty, promote blood circulation, help to improve sleep, as well as radiation protection, calm the nerves, relieve fatigue, relieve hangover, brighten the eyes, sterilize inflammation, relieve internal organ damage, Efficacy in preventing respiratory tract infections and so on. ”

"Isn't this almost like a miracle drug?"

Yang Hao asked curiously, "Then why haven't you heard of anyone using it in medicine?"

"Just because you have it doesn't mean you can, not to mention that you have to be able to use it!"

Liu Yiyan said with some regret: "All medicinal materials need to cooperate with each other, otherwise the efficacy of medicine is very low, now that biotechnology is developing rapidly, there are too many drugs that can be replaced, and everyone is trying to be convenient, plus the loss of the prescription, there are few people who will specifically find it for medicine!"

"That's a shame!"

Yang Hao nodded with a little disappointment.

But that's right, even Chen Song has to use hundreds of medicinal materials to take a bath, and this is only one, and it is estimated that it really can't exert any medicinal effect.

I can't imagine that such a powerful medicinal herb will be reduced to an ornament because of the loss of the prescription!

It's really a time passing, things are not people!

Chen Song looked at Yang Hao and said with a smile: "However, it is still very effective to grind it directly into powder, it can stop bleeding and build muscles!"

"That's not bad!"

Yang Hao pondered when he would find amber and grind it into powder and put it on his body in case of emergency.

After all, local drugs are scarce, and the terrain is precipitous, so it is inevitable that you will suffer some external injuries!

Chen Song turned his head to Liu and asked, "Master Liu, I used to encounter amber that was used in medicine, although the smell is a little similar to this one, but it looks completely different, are these two not the same variety?"

Liu Yan replied: "It's the same kind!"

He knows a thing or two about Chinese medicine and is also familiar with amber.

He used to use amber specifically to pass through the meridians, so he knew what the problem Chen Song was talking about.

"The same kind?"

It's not like that!

Whether it's the intensity of the flavor or the color and texture, it feels like the two are very different!

"Blood amber is not born with blood amber, but refers to the natural color blood amber that has not been optimized, and the original resin that forms blood amber is no different from that of golden amber and tea amber, only because in the process of amber formation, the environment in which the resin is buried is relatively special, and blood amber is formed. ”

Liu Yiyan continued to answer: " Blood amber can be said to be a layer of red oxide layer formed on the surface of amber, slowly penetrating inside, and finally the whole piece becomes an oxide layer, so that the amber appears red, some have not yet formed an oxide layer, the innermost position is actually golden amber or tea amber, so the red only exists in the oxide layer, and the original color will disappear directly, so it looks different from ordinary amber, and the amber used in medicine is generally not directly ground into powder, but the amber rough with many cracks is ground into particles for preservation, and the color is yellow and gray。 ”

Chen Song thought about it, it was indeed the case!

In the past, amber used in medicine was irregular in the form of grains, lumps, stalactites and loose grains, and sometimes contained plants or insects.

It is ground into a powder when needed, and the color is yellow, brownish-yellow, reddish-yellow or pale yellow.

"In addition, in the process of formation, because of the oiliness of the resin, it has a smell of oil, and the blood amber rough generally has a black carbonization layer, you two, because the oxide layer is oxidized to the extreme, resulting in the original surface of the carbonization layer has fallen off, the surface has formed a unique yellow mud, has covered and weakened its own oil smell, compared with ordinary amber, the taste has become faint, but the taste inside will still be obvious, but because of the oxide layer, there is no ordinary amber oil luster!"

"Thank you, Master Liu!"

After Chen Song heard this, his doubts immediately dissipated.

Yang Hao also secretly remembered on the side.

It's really full of knowledge, and knowledge is increasing again!

Liu Yiyan raised his head slightly, and asked the two: "By the way, how have you practiced the color discrimination under the jade lamp in the past few days?"

In the past few days, he hadn't taken care of Yang Hao and Chen Song, and he hadn't even entered the room full of jade samples.

Only during the meal did he answer the questions that Chen Song and Yang Hao occasionally raised.

Chen Song thought for a moment and replied: "For jadeite, the green hue in different light intensities can be roughly distinguished. ”

Yang Hao also replied: "I can already identify green in the light." ”

Liu Yiyan saw that the eyes of both of them were a little swollen, especially Yang Hao, who was like a pair of goldfish eyes, and nodded very satisfied.

It seems that both of them have been very conscious and working hard these days!

He smiled and asked, "Have you come to any conclusions about the green color of the jade?"

Yang Hao said: "Yes, the green of jade is really different from the green of other things!"

"Oh, in that case, I'll test you!"

Liu Yan asked directly: "What is the bright green on the jade under the light?"

Yang Hao replied without thinking: "The green color under the light is very pure and rich, and it can't have the slightest black tone!"

Liu Yiyan nodded and continued to ask, "What about the emerald green?"

"Green should be alive, if it is born in a glass ground, it must be as shaky as green water, and if it is in other textures, the color is more bright green, it is standard green.

"What about blue-green?"

"The green has a blue tinge in it, it looks like a green with a bluish tint, and the blue hue looks like it has to be dull. ”

"Where's the green?"

"The color is lighter, the green is dark, but slightly cloudy. ”

"What about Dark Green?"

"The green is intense, but it looks dark and not sunny, but it doesn't deviate from the green hue. ”

"What about black and green?"

"The green should be very strong, so thick that it has a black tinge. ”

"How can you tell if it's pale green?"

"The green is lighter, some whitish, not bright enough, and even carried by the yellow light from the flashlight. ”

"Not bad!"

Liu glanced at it and asked again, "What about Yanglu?"

"Yang Green ....."

Yang Haosi was directly silent.

He is now trapped in the problem of yang and green, and he always feels that the color difference cannot be grasped, and there is always a deviation every time.

Chen Song saw Yang Hao, who was thinking hard, and replied directly: "Green should be fresh, yang, with a slight yellow tone, and the yellow tone should pay attention to attenuating the light intensity of the yellow light flashlight, and it should look very bright!"

Liu Yiyan nodded and said, "You still have to be more skilled, after all, the same color on the jadeite appears in different positions, and its hue will also change, but this change is regular!"

"Understood!"

Chen Song and Yang Hao knew it in their hearts.

Even Yang Hao was a little excited after listening to Liu Yiyan's words.

According to what Liu Yiyan said, as long as you grasp the law of the slight change of color difference, then on the same rough stone, you can judge the color change between the two positions according to the color of two different positions.

Liu Yiyan smiled with satisfaction, turned around and walked towards the small courtyard.

After seeing Liu Yan enter the small courtyard, Yang Hao handed the uncracked piece of blood pearl rough stone in his hand to Chen Song, and said with a smile: "Here you go." ”

"Brother Yang, you gave it wrong, right?"

Chen Song looked at the Blood Amber Rough Stone handed over by Yang Hao and did not take it.

"That's right, this piece is yours!"

Yang Hao stuffed the uncracked blood pearl rough stone into Chen Song's hand.

"But my piece is cracked!"

Chen Song used his hand to block the blood pearl rough stone that Yang Hao stuffed over.

Yang Hao saw that Chen Song didn't answer, and said, "What she asked you to bring me should be this cracked piece!"

As he spoke, he lifted up the piece of blood pearl rough stone full of cracks and shook it in the corner of Chen Song's eyes.

Chen Song was stunned for a moment and said, "What she asked me to give you is the uncracked one!"

"Hey, don't lie to me, I know you're comforting me!"

Yang Hao sighed, stuffed the uncracked blood pearl rough stone directly into Chen Song's hand, patted Chen Song's shoulder, and turned around and walked towards the pile of rough stones in the compound.

Chen Song reluctantly took this uncracked blood amber rough stone and followed.

I don't know how Yang Hao found out!

Yang Hao found a large rough stone cut in half, and lay down on one of the halfs, with his head resting on his hands, looking at the sky with some sadness.

Chen Song followed behind, and he didn't know how to speak for a while.

He simply lay down on the other half of the rough next to him and looked at the sky.

The sky was blue, with only a few sparse white clouds drifting.

The morning sun is warm, and the cool breeze carries a fresh smell of grass and trees, which makes people feel more comfortable.

"Am I stupid?"

Yang Hao looked at the sky, as if he was talking to himself, and as if he was asking Chen Song.
