How much do you know about the effects and functions of Rhizoma Cyperi?

Honeysuckle is a common Chinese herbal medicine. It is also called money grass and honeysuckle. The whole plant can be used to treat various diseases. It has a good effect in treating gallstones, cholecystitis, and trauma. It must be used correctly under the guidance of a doctor.

1. Hemostatic effect: Passiflora has been used as a hemostatic agent in clinical practice for decades, but animal experimental studies on its hemostatic effect have not reached a consensus.

Early research reports indicate that both Rhizoma Cyperi and its alcohol extract have the effect of promoting blood coagulation. The crude extract also has the effect of promoting blood coagulation, and has the effect of constricting surrounding blood vessels when frog legs are perfused. After intravenous injection of flavin in mice, bleeding time was shortened by 45%. Intravenous injection in rabbits can greatly shorten the blood clotting time and increase the platelet count. When the femoral artery of the dog was bleeding experimentally, local application of huang powder and pressure had a certain hemostatic effect.

2. Effect on the circulatory system: Intravenous injection of ethanol extract of Radix Passiflorae to anesthetized rabbits and dogs can increase blood pressure and stimulate breathing, while the alcohol extract of its water extract can lower the blood pressure of rabbits. When the blood vessels of rabbit ears and frog hind limbs are perfused, low concentrations cause the blood vessels to contract, while high concentrations cause them to dilate. There are also reports indicating that when the infusion and extract of Radix Phellodendri ternata were perfused into the rabbit ear blood vessels, there was no effect at low concentrations, but a dilation reaction was observed at high concentrations, and it could counteract the vasoconstrictive effect of adrenaline. The extract and flavin have a cardiotonic effect on the isolated frog heart; they can increase the heart rate and contraction strength of frogs and toads, while the ethanol extract of the water extract has an inhibitory effect on the isolated frog heart.

3. Effect on smooth muscle: The ethanol extract of the water-extracted part has excitatory effects on the isolated intestine of rabbits and guinea pigs at low concentrations and inhibitory effects at high concentrations. Passiflora lactone can reduce the contraction amplitude and tension of isolated rabbit intestines, and then stop intestinal movement in a relaxed state. It also has an inhibitory effect on the peristalsis of the small intestine in rats.

4. Anti-inflammatory effect: Water extract and alcohol and water extract have anti-inflammatory effect on rabbit conjunctivitis caused by mustard oil or staphylococcus infection. For the former, alcohol and water extracts have better anti-inflammatory effect, while for the latter, water extracts are better. In vitro tests show that the water extract has a stronger effect on the inhibition of staphylococcus. Its anti-inflammatory effect is due to the astringent effect of tannins contained in Rhizoma Dioscoreae which can produce condensed tannins (Phlobaphene).
