Hypertension
A small clinical trial demonstrated PJ inhibits serum
angiotensin converting enzyme (ACE) and reduces
systolic blood pressure in hypertensive patients. Tenhypertensive subjects (ages 62 to 77; seven men and
three women) were given 50 ml/ day PJ containing 1.5
mmol total polyphenols for two weeks. Two of seven
patients were also diabetic and two were hyperlipidemic.
Seven of 10 subjects (70%) experienced a 36% average
decrease in serum ACE activity and a small, but significant,
five percent decrease in systolic blood pressure
(Yurdasheva et al., 1978).
