Achyranthes bidentata (produced in Henan, purchased from Kangqiao Traditional Chinese Medicine Co., Ltd.), Uncaria (produced in Shaanxi, purchased from Kangqiao Traditional Chinese Medicine Co., Ltd.), wild chrysanthemum (produced in Jiangsu, purchased from Kangqiao Traditional Chinese Medicine Co., Ltd.). the

Test method 1: Keep the room temperature at 23-24°C, feed the rats for 7 days, fix the SHR rats in a 38°C incubator, and measure blood pressure. 42 rats were divided into 7 groups, 6 in each group, half male and half male. The following 7 kinds of extracts were all prepared according to the preparation method of the foot bath liquid, administered by intragastric administration at a dose of 2.0 g/kg, once a day, for 3 consecutive weeks, and the blood pressure was measured once a week. The test results are shown in Table 1. the

Table 1 Effects of different prescriptions on the blood pressure of SHR rats (mmHg)

The data in Table 1 shows that the antihypertensive effect of the three traditional Chinese medicine compositions of Achyranthes bidentata + Uncaria + Wild Chrysanthemum is better than that of any single medicine or the combination of any two medicines. After three weeks of administration according to the dosage of 2.0g/kg, the antihypertensive effect of the three traditional Chinese medicine compositions is obvious. the

Test method 2: keep the room temperature at 23-24°C, feed the rats for 7 days, fix the SHR rats in a 38°C incubator to measure blood pressure. Take 30 rats and divide them into 5 groups, 6 in each group, half male and half male. The following 5 kinds of extracts with different proportions were prepared according to the preparation method of foot bath liquid, administered by intragastric administration at a dose of 2.0 g/kg, once a day, for 3 consecutive weeks, and blood pressure was measured once a week. The test results are shown in Table 2. the

The influence (mmHg) of the traditional Chinese medicine composition of table 2 different proportions on SHR rat blood pressure

The data in Table 2 shows that when the ratios of Achyranthes bidentata, Uncaria and wild chrysanthemum are respectively 20-80%, 15-70% and 5-50%, the compositions all have obvious antihypertensive effect; When the ratio is 50:35:15, the antihypertensive effect of the preparation on SHR rats is the most obvious. the

Test method 3: SHR rats were divided into 3 dose groups (1.0, 2.0 and 3.0 g/kg) and 1 control group according to their basal blood pressure values, with 12 rats in each group, half male and half male. The prepared foot bath was administered by intragastric administration, and the control group was administered with normal saline, once a day, for 3 consecutive weeks, and the blood pressure was measured once a week. The test results are shown in Table 3 and Table 4. the

The influence (g) of Chinese medicine composition on the body weight of SHR rats of table 3

It can be seen from the data in Table 3 that there is no significant difference in the body weight of the rats in each experimental group and the rats in the control group within 3 weeks. the

The influence (mmHg) of Chinese medicine composition on the blood pressure of SHR rats of table 4

As can be seen from the data in Table 4, the blood pressure of rats in the control group had no change within 3 weeks of intragastric administration of normal saline; after administration of SHR rats for 1 week, all dose groups had antihypertensive effects; after 2 weeks and 3 weeks, the antihypertensive effects It can be maintained, and the highest pulse pressure difference is between 14.52-18.44mmHg. However, the data show that the antihypertensive effect has no obvious correlation with the administered dose. the
