What are the medicinal values ​​of Di Gu Pi?

Traditional Chinese medicine is a profound and extensive science. Many Chinese medicines are plants or plant rhizomes, such as Rehmannia glutinosa. These seemingly useless things are very effective in treating diseases. Many inconspicuous plants can cure difficult and complicated diseases. Therefore, it is very important to know the medicinal value of these plants. Today we will talk about the medicinal value of Rehmannia glutinosa.

①Effects on the cardiovascular system

The infusion, tincture and decoction of Radix Rehmanniae have obvious antihypertensive effect on anesthetized dogs, cats and rabbits when injected intravenously, accompanied by slower heart rate and faster breathing; the effect of infusion seems to be better than that of decoction; repeated administration can produce varying degrees of rapid tolerance. The concentrated tincture also exhibits a long-lasting and stable antihypertensive effect when injected intramuscularly into anesthetized dogs and cats or when the decoction is administered orally to unanesthetized rats. The antihypertensive effect of Lycium bark is related to the central nervous system, and it may also have the effect of blocking sympathetic nerve endings and directly dilating blood vessels. During the period of hypotensive treatment, there were no obvious changes in the electrocardiogram except for a slower heart rate and a decrease in T waves. A toxic dose could cause partial or even complete block of atrioventricular conduction in the guinea pig's heart.

②Hypoglycemic effect

When rabbits were gavaged with a decoction of Rehmannia glutinosa, their blood sugar levels first increased for a short time, then decreased for a long time, and had not recovered after 4 to 8 hours. It has no significant antagonistic effect on hyperglycemia caused by injection of epinephrine. Subcutaneous injection of extract in rabbits also lowers blood sugar

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.

③Antipyretic effect

The bark of Chinese wolfberry has a significant antipyretic effect on rabbits with artificial fever. Its ether extract and the aqueous extract of the residue after ethanol extraction had no effect, while the ethanol extract, water extract or aqueous extract of the residue after ether extraction all had an effect. Its antipyretic effect is weaker than that of aminopyrine and is approximately equal to that of other antipyretics.

Are you surprised to know the medicinal value of Rehmannia glutinosa? I didn't expect that such an inconspicuous thing could have so many benefits. But although the bark of Rehmannia has so many medicinal values. But you should still be careful when using it. Medicines have side effects. Therefore, when using the bark of Rehmannia glutinosa, it should be used under the guidance of a doctor.
