Deer blood is well-known, but few truly understand it!

Everyone must have heard about Qianlong drinking deer blood, right? How much do you know about deer blood? I bet there must be a very small number of people who are particularly knowledgeable about deer blood, right?

1. Collection method

After the industrial production of deer blood products has been realized, the demand for deer blood has increased significantly, and safe, convenient and scientific collection methods have emerged as the times require. The basic method of collecting deer blood now is to first conduct a health check on the deer's body, and all indicators must meet the requirements before blood can be collected. Fast for 8 to 12 hours before blood collection, then anesthetize the deer and fix it, disinfect the vein, insert a 16-gauge blood collection needle into the vein of the deer body and slowly suck the blood out with negative pressure; The fresh deer blood can be subpackaged and sterilized and stored at a temperature of -20°C to 4°C. The fresh deer blood can also be directly made into freeze-dried powder for storage by low-temperature freezing process.

The blood collection cycle is 7 to 15 days, and the blood collection volume at one time is ≤800 ml. Sterilized fresh deer blood can be stored in an environment of 0℃~4℃ for 10~15 days; in an environment of -10℃~-20℃, it can be stored for 15 days~3 months; freeze-dried deer blood powder can be stored in a vacuum state Can be stored for 1 to 2 years.

2. Component testing

The water content of deer blood is 80% to 81%, organic matter accounts for 16% to 17%, mainly protein, which contains albumin, r-globulin and 19 kinds of amino acids, especially cystine and lysine, which account for the total The percentages of amino acids are 14.56% and 11.7% respectively. There are also collagen (enhance skin elasticity), proteoglycan (enhance joint elasticity), chondroitin sulfate (enhance bone elasticity), glucosamine sulfate, glucosaminoglycan (lubricate joints), hyaluronic acid, nucleotides (anti aging), gangliosides (improve memory and brain tissue vitality), etc.; inorganic substances account for 3% to 4%, and the main elements include germanium, selenium, zinc, magnesium, lithium, nickel, manganese, copper, iron, Calcium, phosphorus, boron, barium, potassium, sodium, aluminum, etc., among which phosphorus and iron have the highest content, phosphorus is 59.2 mg/g, and iron is 250 mg/g.

Deer blood also contains a variety of enzymes, lipids, free fatty acids, sterols, phospholipids, hormones, purines, vitamins and polysaccharides. Among enzymes, especially superoxide dismutase, glutathione oxidase, and dehydrogenase, which have anti-aging effects, are high in content; among phospholipids, there are mainly phosphatidylethanolamine, phosphatidylcholine, hemolytic Phosphatidylcholine, sphingomyelin (sphingomyelin), etc.; in free fatty acids, there are stearic acid, linolenic acid, linoleic acid, oleic acid, etc.; in hormones, there are serum testosterone, estradiol, progesterone , cortisol, growth hormone, etc.; in purines, there are xanthine, hypoxanthine, adenine and guanine; in vitamins, there are vitamin E, vitamin A, vitamin B1, vitamin B2, vitamin B6, vitamin B12 , nicotinic acid, etc.

3. Efficacy research

anti aging

Deer blood preparation was injected into old rats, and the content of lipid peroxide (LPO) and the activity of superoxide dismutase (SOD) in the serum and liver and brain tissues of the rats were measured using biochemical methods. The liver and brain cells were observed using transmission electron microscopy. of ultrastructure. The results showed that the LPO content in the serum and liver and brain tissue of rats in the test group was reduced or even eliminated, SOD activity increased, the ultrastructure of liver cells was normal, and the fat brown particles in brain neurons were significantly reduced compared with the control group, indicating that deer blood can Play anti-aging effect.

wound healing

The test rabbit was bled 10%, and 0.72-0.75 grams of skin and flesh was cut off from the left thoracolumbar area, causing external trauma to the rabbit. The test group was subcutaneously injected with 0.5 ml/kg of deer blood preparation once a day for 18 consecutive days; the control group was injected with normal saline. The results showed that the weight gain, plasma protein content and red blood cell count of the test group were significantly higher than those of the control group, and the wound healing rate was 72.43%; while the wound healing rate of the control group was 59.24%.

Anti-fatigue, hypoxia resistance, cold resistance

Oral deer blood was given to the test mice, and 20 ml/kg of body weight was gavaged every day for 7 consecutive days, and then the mice were allowed to climb poles and swim. Compared with the normal saline control group, the rod climbing and swimming time of the mice in the experimental group were significantly prolonged. Other experiments have shown that the survival time of mice can be prolonged under hypoxic conditions, and the survival rate of mice under extremely cold conditions can be significantly improved. Tests have shown that deer blood has significant effects on anti-fatigue, hypoxia and cold resistance.

Enhance sexual function

Minor normal mice and castrated adult mice were divided into test groups and control groups. The test group was orally administered deer blood products at a rate of 20 ml/kg of body weight per day, while the control group was given an equal amount of normal saline by gavage for 20 consecutive days. The results showed that the sexual organs of the mice in the test group grew significantly, but the growth of the sexual organs of the young mouse test group was not as obvious as that of the castrated test mice. The sexual organs of mice in each control group showed no growth. It shows that long-term oral administration of deer blood products can enhance sexual function.

Accelerate metabolism, enhance immune function

Oral administration of deer blood to rabbits can make their body weight increase rapidly, and the total liver weight increases significantly (P<0.05); blood routine test results show that the serum total protein level of rabbits taking deer blood increases significantly (P<0.05 ), the hemoglobin level was significantly increased (P<0.05); the rod-shaped granulocytes, eosinophils, basophils, monocytes, lymphocytes (also known as immune cells) ) increased significantly. It can be concluded that deer blood can improve the anabolic efficiency of the animal body, accelerate the growth of the animal, and enhance the immune function.

4. Identify authenticity and falsehood

Deer blood is produced in very small quantities, so it is very valuable. Fresh deer blood is not easy to preserve, and there are very few fresh deer blood products on the market, so they are expensive. Since deer blood products are mostly in the form of powder, granules, capsules, oral liquids, health wines, etc., it is difficult to visually identify the authenticity and are easy to be counterfeited. Therefore, when purchasing deer blood products, you must choose a well-known brand with a good reputation.

If the deer blood product is in the form of granules, you can take one granule and put it into a transparent cup filled with cold boiled water. The genuine deer blood granules dissolve very slowly, and when they fall straight to the bottom of the cup, a line will be dragged out in the water. A long red band; while the fake product melts faster and spreads around in the water.

Deer blood wine can be roughly divided into two types: simple and compound, and simple deer blood wine is divided into whole blood wine, defibrin wine and blood plasma wine. Whole blood wine is directly infiltrated with deer blood into 50% white wine, and the content of deer blood is 10% to 15%. Defibrin wine is continuously stirred in deer blood with bamboo chopsticks wrapped with gauze, and the fibrin in the blood is adsorbed on the gauze. , It will be layered when it is still, and there will be sediment at the bottom of the wine bottle, and the upper part will be transparent orange-yellow; when it is shaken, the sediment will rise, and the color of the wine will become cloudy purple. Plasma wine is made by extracting all the formed components in the whole blood, leaving only the plasma part and mixing it with 50% white wine. The color of plasma wine is orange and transparent. Compound deer blood wine is prepared by mixing deer blood with different Chinese medicinal materials. Due to different medicinal materials, the color and clarity of the wine are also different.

5. Contraindications

Drinking raw deer blood is a bad habit and should not be promoted. In ancient times, drinking raw deer blood was a way of maintaining health for the royal family. The method is to tie the deer, with the head low and the tail high, and a long iron pipe is inserted into the deer's body, and the blood fills the pipe for a long time. In some cases, a silver pipe is inserted into the bridge of the deer's nose, and the blood flowing from the deer's nose is sucked directly. .

In modern times, some deer farms advertise in front of sawing antler, asking those who are willing to drink antler blood to come on time and drink the hot blood directly. According to reports, a sika deer can receive 10 cups of blood (100 ml/cup) when sawing its antler, and a red deer can receive 30 cups of blood when sawing its antler. Each cup sells for 300 to 500 yuan. Drinking raw deer blood is very unhygienic. The biggest disadvantage is that it is unsafe. Unsterilized deer blood contains bacteria, viruses, parasite eggs and other harmful substances, and is too hot. Drinking it directly will only cause harm to the body. It won't have much health care effect.

People with deer blood heat, yin deficiency and excessive fire or excess fire, patients with high blood pressure, diabetes, kidney disease and abnormal liver function, pregnant women, etc. should use it under the guidance of a lifetime, and children should also eat with caution.
