What is Huaishan? What are the effects and functions of Huaishan?

　　Huaishan is also called yam or yam. It has high edible value when cooked. There are many functions and functions of yam. It can be eaten with sugar. It has a soft and smooth texture. It is very satisfying to eat some. Let’s learn about the relevant knowledge about yam.

　　If we know Huaishan, we can start with the effect of Huaishan: nourishing the spleen； Nourish the lungs ； Strengthen kidney ； Yi Jing. Indications: Spleen deficiency and diarrhea ； Swelling due to lack of food ； Cough and asthma due to lung deficiency ； quench thirst ； nocturnal emissions ； Take it off ； Kidney deficiency Frequent urination； External use to treat carbuncles ； Scrofula

　　Huaishan has the effect of lowering blood sugar, which can be proved in some experiments (1). 1.1 Effect on blood sugar of alloxan diabetic mice: Kunming mice, weight 20.6±1.3g, male, randomly divided into groups. The mice in the experimental group were given 9 mg/kg of alloxan intravenously, and blood glucose was measured from the orbits at 72 hours. Those with blood glucose above 250 mg/dl were selected for the experiment. The average blood glucose difference between the groups was not more than 10 mg/dl during grouping. The administration groups were given yam decoction 30.0 g/kg iv, once a day. ； Or 2 times a day (total 60g/kg) for 10 days. A control group was also established. The animals were fasted for 2 hours before the last administration, and blood was collected from the orbit 3 hours after administration, and the whole blood was measured using the o-toluidine method. Grape sugar. Compared with the control group, the administration group could significantly reduce the blood sugar of normal mice and alloxan diabetic mice.

　　Huaishan has the effect of lowering blood sugar, which can be proved in some experiments. (2) 1.2 Effect on the increase of blood sugar in mice caused by epinephrine: The mice were randomly divided into the control group, the epinephrine group and the epinephrine-10-yam group. The dosage and route of administration of yam water decoction were the same as before. The control group and epinephrine group were given the same amount of water every day. 2 hours after the last administration, the epinephrine ten yam group was given ip epinephrine 0.2mg/kg, and the control group was given ip normal saline. Blood was taken 30 minutes after injection to measure blood sugar. Ig yam decoction 60g/kgx10 days could significantly resist the increase in blood sugar in mice caused by epinephrine.

　　Huaishan has the effect of lowering blood sugar, which can be proved in some experiments. (3) 1.3 Effect of preventive administration on the increase in blood sugar in mice caused by alloxan: mice were randomly divided into groups, and the administration group was given 30 or 60g/kg of yam decoction for 10 consecutive days, and a control group was also established. Three hours after the last administration, mice in the administration group and control group were given iv alloxan 90 mg/kg. After 72 hours, blood was taken to measure blood sugar. Compared with the control group, the blood sugar of the administration group was significantly reduced, indicating that preventive administration of yam can resist the increase in blood sugar in mice caused by hemoxanil.

　　Huaishan has the effect of lowering blood sugar, which can be proved in some experiments. (4) The effect of 1.4 on the increase in blood sugar in mice caused by glucose: 7 groups of normal mice, 3 administration groups, ip daily yam decoction 30g/kg, and the other 4 as the control group. They fasted for 2 hours before the last administration, and then immediately took blood from the control group of 1 group, and used its blood sugar as zero-hour blood glucose. The other 3 administration groups and 3 control groups received ip glucose 2g/kg 1 hour after the last administration. At 30, 60 and 120 minutes after injection, blood was taken from one administration group and one control group, and blood glucose was measured. Compared with the control group, the blood glucose of the administration group at different times was significantly lower than that of the corresponding control group, indicating that yam can resist the increase in blood glucose in mice caused by exogenous glucose.

　　The efficacy and role of Huaishan are also shown in: 2. Regulating the body's response to non-specific stimuli: 22 Kunming mice were divided into 2 groups in the normal pressure hypoxia tolerance test. 0.2ml/mouse of yam water decoction (containing 1g/ml crude drug) was injected into the control group. After 30 minutes, they were injected with 0.2ml/mouse of physiological saline. After 30 minutes, they were put into a wide-mouth grinding bottle containing 20g of soda lime, sealed with Vaseline, and the survival time of the mice was recorded. Compared with the control group, yam can significantly extend the survival time of mice, has a very significant effect on normal pressure and hypoxia tolerance, can significantly reduce the damage to mice's organs in a hypoxic environment, and improve tolerance.

　　The efficacy and functions of Huaishan are also reflected in: 3. Effect on immune function

　　The efficacy and role of Huaishan are also shown in: 3.1 Effect on the weight of immune organs: 20 Kunming mice were used. The experimental group was given 0.2ml/mouse of yam water decoction (containing 1g/ml crude drug) ip for 7 consecutive days, and the control group was injected with 0.2ml/mouse of physiological saline. 24 hours after the last administration, the animals were sacrificed, and the body weight, thymus weight and spleen weight were immediately weighed, and the thymus index and spleen index were calculated. Compared with the control group, yam could significantly increase the spleen weight of mice but had no obvious effect on the thymus.

　　The efficacy and role of Huaishan are also reflected in: 3.2 Effect on the clearance of carbon particles in mice: There are 12 Kunming mice. The experimental group was injected with 0.2ml/mouse of yam water decoction (including crude drug ig/ml) for 7 consecutive days, and the control group was injected with 0.2ml/mouse of physiological saline. 24 hours after the last administration, each mouse tail was i. v Treated Chinese carbon ink 0.1ml/10g (filtered commercial ink, diluted 3 times), 0.5 and 10 minutes after injection, take 20ml of blood from the retroocular venous plexus, dissolve it in 21% NaHCO3 and let it stand for 1 hour, measure the absorption value at 650nm, and calculate the clearance index. Yam can significantly enhance the carbon particle clearance effect in mice. Yang Zhonglin et al. also used the carbon particle clearance experiment as an indicator to study the effects of raw yam, bran-fried and soil-fried yam on the non-specific immune function of mice. The results showed that there were very significant differences between each administration group and the control group. The raw product was stronger than the bran-fried and soil-fried products, suggesting that raw yam is suitable for replenishing qi.

　　The efficacy and role of Huaishan are also reflected in: 3.3 The impact of cyclophosphamide on suppressing immunity: There are 20 Kunming mice. The experimental group was continuously injected intraperitoneally with 0.2ml/mouse of yam polysaccharide solution for 10 days, dll was injected with cyclophosphamide 0.4ml/mouse (5mg/ml), and dl3 was taken to measure the white blood cell count. Yam polysaccharide can effectively resist the immunosuppressive effects of cyclophosphamide.

　　The efficacy and role of Huaishan are also shown in: 4. The effect on the small intestinal motility of mice: 20 Kunming mice were divided into 2 groups and fasted for 24 hours. The experimental group was treated with 10ml of yam decoction (containing 1g/ml of crude drug) + 0.5g activated carbon (commercially available), and the control group was treated with 10ml of normal saline + 0.5g of activated carbon, ig. After 20 minutes, the animals were immediately sacrificed by spinal cord dislocation, the small intestine was taken out and flattened, the distance (cm) of the carbon powder pushed from the pyloric sphincter to the end of the small intestine was measured, and the percentage of this distance to the total length of the small intestine was calculated. The results show that yam has the effect of stimulating small intestinal movement and promoting the emptying of intestinal contents.

　　The efficacy and functions of Huaishan are also reflected in: 5. Other nutrients contained are related to mucus and amylase, which have a nourishing effect and can aid digestion. Stop diarrhea. Expectorant.

　　The efficacy and role of Huaishan are very obvious in improving the body's immunity, lowering blood sugar, tonifying the spleen and nourishing the skin. Eating Huaishan is very beneficial to the body.
