Introduction: The content of this issue is somewhat heavy, please watch it with your family.
Recently, Ah Zhen coincidentally obtained some non-medicinal parts of the snake, the head of the snake.
Although the fangs of the snake are forced to look, it is a bit scary.
But it still aroused Ah Zhen's enthusiasm for studying the snake.
How to say that animal medicinal materials in the market is still chaotic, rare to have ready-made materials, can not be studied well?
"Small soup source, pearl powder", first guess which is the snake in the picture below, this season to be careful of snakes
The answer is found in the text.
Regarding the snake, Ah Zhen's biggest concern is how to distinguish whether it is poisonous or not
01 Look at the snake's head
Venomous snake, with a triangular head, like a "spear", is aggressive;
Non-venomous snake, the head is oval, the pupils are also round, it looks relatively thick
02 Look at the color
Venomous snakes, with bright skin patterns, are very much in line with the saying of "snake and scorpion beauty";
There is no venomous snake, and the pattern on the surface of the body is not obvious
03 Look at the teeth
A venomous snake with two large poisonous fangs and two large tooth marks on the wound;
Non-venomous snakes, non-venomous teeth, wounds will appear four or two rows of jagged, shallow and fine tooth marks
Azhen safety tips
Encounter a snake on the road, don't provoke it, it may just come out to relax, the so-called "well water does not violate the river water."
If you are really unfortunate enough to be bitten, the first rescue measure at the scene is to tie it around 5 cm near the heart of the wound to prevent the absorption of venom, and then seek medical attention urgently.
If possible, it is best to note the morphological characteristics of the snake for easy diagnosis.
Believe that advanced medical care has been able to solve the problem of venomous snake bites.
Origin of the name of the snake
The snake introduced by Ah Zhen today is a real poisonous snake, and it has all the characteristics that a poisonous snake should have, but it has been rated as the "Four Treasures of Puchun".
What's going on?
The 2020 edition of the Chinese Pharmacopoeia contains a dried body of the five-step snake Agkistrodonacutus (Güenther) of the viper family, and is the only species in the genus Diplodocus in the family Viperidae, deinagkistrodon.
Through the mysterious power of Chinese combined with the picture, it is possible to understand the meaning of "sharp kiss" - the snake's snout (nose tip) is upturned, which is one of the most proud features of the snake, and it is unique when walking with wind.
Therefore, the answer to the upper question is "C".
The snake, known as the "white flower snake", was first published in the Song "Kaibao Materia Medica", also known as the "snake with a nose".
The Bencao Tu Jing: "Present-day Qianzhou, Puzhou, and Dengzhou all exist." Its writing is better than white flowers. ”
The "Materia Medica" records that the white flower snake: "The nose of the snake is downward, the nose of the snake is up, and the back has a square victory pattern, which is named after it."
The name of the snake first appears under the white flower snake in the "Compendium of Materia Medica", and the name is "snake".
"Flower snakes, lakes, and Shu are all there, and now they are only known as snakes." However, there are not many lands, and the goods and lawsuits taken by the city are all from the mountains of Xingguo Prefecture in Jiangnan. Its snake dragon head tiger mouth, black matter white flowers, flanked by twenty-four Square Shengwen, abdomen with rosary spots, four long teeth in the mouth, a Buddha fingernail on the tail, one or two points long, intestinal shape like a bead. ”
Ancients have sorted out the traits of the snake through just a few words, and many identification points have been used to this day, although the hand-drawn drawings are somewhat intriguing.
A. Song "Materia Medica" (quoted from "Evidence-like Materia Medica")
B. Zhang Ben's Compendium of Materia Medica
C. Ming "Materia Medica"
Reference: Zhou Nana, Materia Medica of The Snake and the Snake
The snake venom of the snake belongs to the blood circulation toxin, derived from its venom glands, and the snake's head needs to be removed when medicinal.
After concoction, the snake is widely used in clinical practice and has the effect of dispelling wind, communication and antispasmodicity. It is used for rheumatism, numbness, hemiplegia, convulsions, tetanus, leprosy, scabies, etc.
In recent years, the wild resources of animal medicinal materials are in short supply, and most of them have shown a trend of artificial breeding, but due to the strong demand for medicinal snakes, many fake and inferior snake medicinal materials have appeared, such as weight gain, skin, etc., and related reports are not uncommon.
Ah Zhen shared several methods of identifying snakes.
Identification of snakes
On how to identify snakes, Ah Zhen will introduce several aspects.
1. Identification of traits
a. Upturned nose: the head is slightly upward in the middle, triangular and flattened, and the snout end is up
b. Rosary spots: the abdomen is propped open or not, grayish white, with large scales, and black round spots.
c. Fang Sheng pattern: There are 17 to 25 "V" shaped stripes composed of black brown and light brown on both sides of the back, and the two upper ends of the "V" shape are connected on the dorsal midline, and they are square after unfolding.
d. Buddha fingernails: the tail is suddenly thin, and there is a triangular dark gray scale at the end.
The above four tips, "nose head", "square sheng pattern", "rosary bead spot" and "Buddha nails", you may have heard it tired of.
Is there anything else?
Ah Zhen took this question to discuss with Sun Guangcai Pharmacist.
He unreservedly shared four new tips based on years of work experience to identify whether a snake is a skinny snake.
"Skinned snake": refers to a snake made by processing the skin of a genuine snake on the flesh of other non-snake snakes.
This kind of snake has classic identification characteristics, but it has been stolen beams and columns, if the genuine product is purchased, then what is bought is a piece of snake skin and a piece of ordinary snake meat plus a pool of glue.
The specific identification tips are as follows.
a. Open ridge: the fissure between adjacent vertebrae is larger, and the corresponding ridge scales collapse at the fissure to form a concave socket.
b. Wheat ear pattern: The opposite line of the bore surface is wheat ear-shaped.
c. Arrow throat: The two ribs near the larynx (whether they are ribs to be examined) intersect in the larynx in an arrow-like manner.
d. Mulberry skin meat: The breakage of snake meat is fibrous, with the texture of the mulberry white skin section.
2. Microscopic identification
In 2019, Professor He Qian of Jinan University conducted a more systematic study on snakes.
The following content is derived from the research results of his master's thesis "Research on the Quality Grade Standards of Snake Herbs and Tablets".
Micrograph of snake powder (a~D bone fragment e~h keratinous scales i~l scale m~p fat oil drops q~t rhabdomyofibers)
The snake powder is yellowish-white in color.
Bone fragments: cylindrical, triangular, pebble-like, hoof-like and other shapes, bone fragments are smooth, pale yellow or transparent in color
Horny scales: thickened texture, rounded, ovate, polygonal, papillary protrusions, tile-like arrangement.
Scales: Brown dorsal scales are common, rounded or polygonal, containing granular pigments, rare white dorsal scales
Rhabdomy muscle fibers: more common, with a parallel arrangement of fiber textures.
Fatty oil droplets: more common, varying in size, and clustered into clumps.
3. Azhen Laboratory
Recently, Ah Zhen bought a lens part, and the mobile phone a touch, you can see a lot of novel things (micro-traits), follow-up will continue to update.
Share some pictures of snakes with "Little Soup Source, Pearl Powder" here.
Micro-traits of snakes
About the snake first introduced so much, any questions can be left in the comment area, AZhen will reply at the first time.
Ah Zhen also wants to collect suggestions and opinions on the theme of some articles (Materia Medica, Authenticity Identification, Quality And Inferiority, Origin Processing, Traditional Concoction, etc.) from the majority of "Small Soup Source, True Pearl Powder" here, and also welcomes everyone to actively submit articles, thank you for your support and help.
