Pharmacological effects

Antibacterial and anti-inflammatory effects

The hot water or ethanol infusion of Senghuang has inhibited Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Bacillus fowleri and Bacillus typhi in test tubes. The aqueous and aqueous-alcoholic extracts of the whole herb have anti-inflammatory effects on the conjunctivitis caused by mustard oil or staphylococcal infection in rabbits. This effect is related to the presence of tannins that can produce condensed tannin (Phlobaphene) in the herb.

Anthelmintic effect

It has a definite insecticidal effect on the cystic larvae and larvae of pork tapeworm, Morpho cestode, and short-film cestode. The rate of tapeworm elimination by cranesol is much faster than that of tapeworm killer.

Effects on the cardiovascular system

Both the infusion and chenopodium have cardiotonic effects on isolated frog hearts; they can increase the heart rate and contraction strength of frogs and toads. In contrast, the alcoholic extract of the aqueous fraction had an inhibitory effect on the isolated frog heart. The ethanolic infusion of Cynogramma sanguinis was administered intravenously to anesthetized rabbits and dogs, which increased the blood pressure. In contrast, the alcoholic extract of its aqueous extract part decreased the blood pressure in rabbits; the vascular perfusion of the hind limbs of rabbits and frogs caused vasoconstriction at low concentration and vasodilation at high concentration. The infusion and aqueous extract of C. senegalensis had no effect on the perfusion of rabbit ear vessels at low concentrations, but showed a dilatory response at high concentrations, and counteracted the vasoconstrictive effect of epinephrine.

Effects on smooth muscle

The ethanolic extract of the aqueous extract was excitatory at low concentrations and inhibitory at high concentrations in the isolated intestinal tubes of rabbits and guinea pigs. The lactone of Cynanchum can reduce the contraction amplitude and tension of the isolated rabbit intestine, and then stop the intestinal movement in a relaxed state; it also has an inhibitory effect on the peristalsis of the in situ small intestine of rats. The infusion has similar adrenaline-like effect on isolated rabbit and guinea pig uterus.
