(1) diuretic effect

After intragastric administration of Sangbaipi Decoction (2G / kg), the urine output and chlorides of rabbits increased significantly within 6 hours and returned to normal within 7-24 hours.

② Antihypertensive effect

In the early years of Japanese people, it was reported that mulberry decoction had a slight and slow antihypertensive effect when taken orally to animals. It was also said that the skin of roots or branches had antihypertensive effect, but roots and new shoots and leaves had no effect. When the extract of ether, hot water or warm methanol was injected subcutaneously into rabbits at the rate of 1G (crude drug) / kg, the blood pressure decreased by 15-25 mmHg. A substance extracted from Cortex Mori was injected intravenously into rabbits at 10 mg / kg, and the blood pressure immediately decreased significantly; the effect still existed after cutting off cervical vagus nerve or cervical vertebra. These effects can be blocked by atropine, so it may be acetylcholine like substance. It can dilate the blood vessels of rabbit ears and contract the blood vessels of frog legs. It can excite the isolated rabbit uterus and slightly promote the secretion of rabbit's infraauricular gland. Injection (artery or vein) has no effect on the contraction of cat's blink membrane, but if it is directly applied on the cervical sympathetic ganglion, it can inhibit the contraction of blink membrane caused by electrical stimulation of preganglionic fibers. The results showed that there was no effect on the back muscle of leech, but the tension of the back muscle of leech could be significantly increased by adding ethrin first and then using it again. The median lethal dose of this substance was 32.7 mg / kg. According to Japanese reports, the extract of Cortex Mori from China has stronger antihypertensive effect and greater toxicity than that from Japan. It contains more acetylcholine like substances.
