Pharmacological effects ① Antihypertensive effect The extract and decoction of the bark have a long-lasting antihypertensive effect on animals. With its extract 5 ml (1 ~ 2 grams of raw medicine) to anesthetized dogs after intravenous injection to produce a significant hypotensive effect, can last 2 ~ 3 hours, showing a "fast tolerance" phenomenon. In 3 renal hypertensive dogs, the decoction was administered daily by gavage at 5-8 g/kg for 4 weeks, and the systolic blood pressure was lowered by only 8-22 mmHg (4-10%) at most, so the efficacy of the treatment was not satisfactory. The concoction and dosage form of Cortex Eucommiae have some influence on the antihypertensive effect, the decoction effect is stronger than the tincture, and the antihypertensive effect of fried Cortex Eucommiae is greater than that of raw Cortex Eucommiae. Cortex Eucommia Ulmoides has antihypertensive effect on cats, but it lasts for a short period of time, and the phenomenon of "rapid tolerance" is not significant. The hypotensive effect on rabbits with cholesterol atherosclerosis is more significant than that on normal rabbits, but it can also produce "fast tolerance". As for the principle of antihypertensive effect, it is preliminary because the active ingredient has not yet been determined. It has been proved that the acute antihypertensive effect is not related to the vagus nerve and is not affected by atropine. For isolated rabbit heart, Cortex Eucommiae was first excited in small amount and then slightly inhibited; its inhibitory effect on the heart was also reported to be related to its pH (pH between 4 and 5), and was adjusted to be excitatory for isolated hearts of both rats and rabbits. Cortex Eucommiae has a direct dilatation effect on normal rabbit ear blood vessels, but the same concentration makes experimental cholesterol atherosclerosis rabbit ear blood vessels were contraction, on the normal rabbit coronary blood vessels and renal blood vessels in the low concentration of the dilatation effect, the high concentration is the opposite, on the atherosclerosis of rabbits coronary blood vessels in the low concentration of contraction was also presented. Since its antihypertensive effect is not directly related to the heart and blood vessels, it is inferred that it is central. ②Diuretic effect The various preparations of Cortex Eucommiae have diuretic effect on anesthetized dogs, and there is no "fast tolerance" phenomenon. It also has diuretic effect on normal rats and mice. Cortex Eucommiae contains 0.4% potassium, so it is inferred that diuresis may be related to potassium. Clinical use of Cortex Eucommiae extract can reduce blood pressure in hypertensive patients and improve symptoms such as dizziness and insomnia. Large doses (20~25g/kg/day) of Cortex Eucommiae decoction to dogs by gavage can make them quiet and sleepy, and not easy to accept external stimuli. The large dose of Cortex Eucommiae also has the effect of inhibiting the central nervous system in mice. Cortex Eucommiae can inhibit the excitatory effect caused by the posterior lobe of the pituitary gland on the isolated uterus of rats and rabbits and make the uterus relax, but the isolated uterus of cats is excited inversely. Some inhibitory effects of a decoction of Cortex Eucommiae on Mycobacterium tuberculosis in the test tube have been reported. Its alcoholic infusion seems to reduce the absorption of cholesterol in the intestines of rats. Concocted Cortex Eucommia Ulmoides: Remove the coarse skin, wash, moisten, cut into squares or silk strips, and dry in the sun. Salt Cortex Eucommia Ulmoides: first use salt with appropriate amount of boiling water to dissolve, take Cortex Eucommia Ulmoides blocks or silk strips, so that with the brine is fully mixed through the absorption, and then placed in the pot, stir-fried with a gentle fire to the degree of slightly burnt spots, remove and dry. (Every 100 pounds of Cortex Eucommiae, with 3 pounds of salt) Cortex Eucommiae after frying, then Cortex Eucommiae gum is destroyed, the active ingredients are easy to decoct.
