1. Effects on the cardiovascular system: The infusion, tincture and decoction of Radix Rehmanniae have a significant antihypertensive effect on anesthetized dogs, cats and rabbits when injected intravenously, accompanied by a slowing of the heart rate and a quickening of breathing; the effect of the infusion seems to be better than that of the 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.

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 was also lowered. Another extract from the root of bearded wolfberry caused a significant and lasting decrease in blood sugar in rats and increased carbohydrate tolerance. Its blood sugar-lowering effect was due to the guanidine derivatives it contained.

3. Antipyretic effect: Rehmannia root bark 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.

4. Anti-pathogenic effect: The decoction of Radix Rehmanniae has a strong inhibitory effect on Salmonella typhi, Salmonella paratyphi A and Shigella flexneri, but has no effect on Staphylococcus aureus; it has an inhibitory effect on the cytopathic effect of the Asian influenza A virus strain Jingke 68-1; it is a low-efficiency antibacterial drug for Mycobacterium tuberculosis.

5. Other effects: The decoction of Radix Rehmanniae has an inhibitory effect on the production of interleukin-2 by spleen cells of normal mice; it has a significant enhancing effect on the reduced production of interleukin-2 by spleen cells of mice induced by cyclophosphamide; and it has an inhibitory effect on the abnormal production of interleukin-2 induced by azathioprine.
