Of the 80 patients, 26 were excluded from the study due to a rise in blood pressure over the expected range, after discontinuation of their pharmacological drugs. Fifty-four patients (31 in the experimental group and 23 in control group) were evaluated. The average
years in the experimental group
years in the control group, which had no signifi- cant difference. Variables such as sex, BMI, posi- tive family history of hypertension, cigarette smoking, and the number of persons in the family had no significant difference between the two groups.
The blood pressure was the lowest on the twelfth day in the experimental group, with an 11.2% decrease of systolic pressure and a 10.8% decrease of diastolic pressure, as compared to the first day. On the twelfth day, the systolic blood pressure of the experimental group decreased 4% and their diastolic pressure decreased 3.6%. This decrease of blood pressure was less on the fourth and eighth days. The difference of blood pressure between the control and experimental groups are significant (with Pf0.00001 for systolic pressure and P f 0.00002 for diastolic pressure).
On the fifteenth day after cessation of drinking tea for 3 days, there was a systolic pressure eleva- tion of 5.6% and diastolic pressure elevation of 6.2% in the experimental group. In the control group, systolic pressure decreased 0.6% and dias- tolic pressure rose 0.4%. Comparing the two groups, we observe a 1.8-fold decrease in systolic pressure and a 2.1-fold decrease in diastolic pres- sure until the twelfth day in the experimental group as compared to the control group. After cessation of drinking tea, there was a 8.7-fold increase in systolic pressure and a 11.9-fold in- crease in diastolic pressure in the experimental group as compared with the control group (Table 1). The variations of systolic and diastolic pres- sures of the patients before and after drinking tea are shown in Figs. 1 and 2.
