Huang Jing, also known as tiger ginger, chicken head ginseng. It is a dry rhizome of the Liliaceae plant Astragalus versicolor or Polygonatum sibiricum. According to the difference of the original plant and medicinal properties, Huang Jing can be divided into ginger-type Huang Jing, chicken head Huang Jing and rhubarb fine three. The original plant of the ginger-shaped Huang Jing is a multifloral Huang Jing, and the original plant of the chicken head Huang Jing is Huang Jing, while the original plant of the Dahuang Jing (also known as a dish-shaped Huang Jing) is the Zhi Huang Jing. Among them, the ginger-type Huangjing has the best quality.
Huang Jing uses rhizomes as medicine. With qi and yin, spleen, lungs, kidney function. For the treatment of spleen and stomach weakness, tired body fatigue, dry mouth, less food, dry lung cough, lack of blood, internal heat Diabetes embolism. It is very effective for diabetes.
Huang Jing's efficacy and effect
1. The role of anti-pathogenic microorganisms:
In vitro tests showed that Huangjingshui solution (1:320) had inhibitory effects on Salmonella typhi, Staphylococcus aureus, and acid-fast bacilli, and 2% borneol had different degrees of inhibition on common pathogenic fungi in Sabouraud medium.
2. The impact on blood sugar:
Rabbit gavage Huang Jing extract, its blood glucose levels gradually increased, and then decreased. Huangjing extract has a significant inhibitory effect on epinephrine-induced hyperglycemia.
3. Anti-fatigue effect:
Huang Jing decoction 17.77% concentration 0.3ml / only intraperitoneal injection, can extend the swimming time of mice.
4. Antioxidant effect:
Huang Jing decoction 20% concentration, 13ml / drink only, continuous 27 days, so that the mouse liver superoxide dismutase (SOD) activity increased, reduced myocardial lipofuscin content.
5. Anti-aging effects:
Huang Jing decoction, 20% soaked mulberry leaves feeding silkworm, has extended the role of silkworm larvae.
6. Hemostasis:
Semen extract methanol extract 40mg / only, n-butanol part 20mg / only, water layer part 20mg / only, intraperitoneal injection, dry ice-methanol frozen mouse tail 1 minute, cut-tail test showed that hemostatic effect, make the mouse bleeding Reduced quantity.
7. For cardiovascular effects:
Huang Jingshui extract 0.16-0.26g/kg intravenous injection, significantly increased coronary flow in anesthetized dogs; 1.5g/kg intravenous injection, antagonistic effect on pituitrin induced rabbit myocardial ischemia, against pituitrin caused by The increase of T wave promotes the early recovery of abnormal T wave; 12g/kg intraperitoneal injection can enhance the tolerance of mice to hypoxia.
8. Antiviral effect:
Polygonatum polysaccharide 0.2% eye drops, 6 times / day, or service Huang polygonum polysaccharide 10mg/kg, 2 times / day, on experimental rabbits with herpes simplex virus keratitis have a therapeutic effect.
9. Other roles:
Huang Jing decoction 6g/kg gavage for 10 consecutive days, can increase the red blood cell membrane Na +, K + - ATP enzyme activity. 40% euphol extract 0.3 ml / only intraperitoneal injection, can improve the mouse myocardial, liver, spleen cells DNA 3H-TdR incorporation rate. The content of cAMP and cGMP in the plasma of Huangjing Decoction (0.5g/kg) decreased, but the cGMP decreased more. Therefore, the ratio of cAMP/cGMP was higher than that of the control group. The contents of cAMP and cGMP in the spleen increased, but cAMP/cGMP increased. No significant change in the ratio.
