What are the effects of Digupi?

I believe that for many friends who suffer from cough diseases, this repeated illness will cause a lot of distress to their body and mind. When the condition is more serious, I feel like my lungs are about to be coughed out, and I can't concentrate on work and study. Therefore, many friends will choose Rehmannia root bark to relieve cough symptoms, so what are the effects of Rehmannia root bark? Regarding this question, please share with me in the next period of time.

1. Effect on the cardiovascular system: Intravenous injection of the extract, tincture and decoction of Radix Rehmanniae to anesthetized dogs, cats and rabbits had a significant hypotensive effect, accompanied by a slow heart rate and accelerated breathing; oral administration to unanesthetized rats also had a significant hypotensive effect. Intravenous injection of 0.375g/kg of Radix Rehmanniae injection to anesthetized dogs can reduce their blood pressure to zero and cause death. Repeated injections of small doses did not show rapid tolerance. The methanol extract of Lycium bark also has obvious antihypertensive activity when injected intravenously into rats at 0.5g (raw drug)/kg. During the antihypertensive period of Di Gu Pi, the electrocardiogram showed a slow heart rate, prolonged PR interval, and reduced T wave. A moderate dose could cause partial or even complete block of atrioventricular conduction in the guinea pig's heart. In addition to the central nervous system involvement, the antihypertensive effect of Lycium bark may also be related to its effect of blocking sympathetic nerve endings and directly relaxing blood vessels. In addition, Lycium barbarum A and Lycium barbarum B have anti-adrenocorticoid and renin effects, which is also one of their antihypertensive mechanisms.

2. Hypoglycemic effect: When rabbits were gavaged with a decoction of Radix Rehmanniae, their blood sugar levels first increased for a short time, then decreased permanently, and did not recover after 4 to 8 hours. It has no significant antagonistic effect on hyperglycemia caused by injection of epinephrine. When the extract was injected subcutaneously into rabbits, blood sugar also decreased. Another extract of the root of bearded wolfberry can cause a significant and lasting decrease in blood sugar in rats and improve carbohydrate tolerance. Its blood sugar-lowering effect is due to the guanidine derivatives it contains.

3. Effect of lowering blood lipids: Intragastric administration of Rehmannia glutinosa extract can reduce the serum total cholesterol content of experimental rabbits, but has little effect on triglyceride content and no obvious effect on liver fat content. Betaine has an anti-fatty liver effect.

The above paragraphs give us a good introduction to the effects of Rehmannia glutinosa. I believe that as long as friends have read the above content carefully, they will have a deeper understanding and cognition of Rehmannia glutinosa. Of course, I also want to tell you that although the bark of Rehmannia glutinosa has so many benefits to our body, we must also be clear about some of its eating taboos, so as to avoid some accidents.
