Green tea lowered blood pressure

In this study, 56 people with obesity-related high blood pressure took 379 mg of green tea extract per day, or a placebo. Before the study and after three months of taking green tea extract, doctors measured blood pressure, sugar, and fats (lipids), protein in the urine, signs of inflammation, and antioxidant levels.

While the placebo group improved slightly, those in the green tea group saw systolic and diastolic blood pressure decline 4.9 and 4.6 mmHg, respectively. And while there were no improvements for placebo, the green tea group had healthier insulin and blood sugar levels, as well as lower LDL cholesterol and higher HDL–the “bad” and “good” cholesterols, respectively. Doctors said the antioxidant and anti-inflammatory action of green tea compounds may explain its health benefits.

Coleus forskohlii improved blood pressure

Doctors said that coleus forskohlii, a tropical perennial plant, may have blood pressure lowering effects. In this study, 41 people with high blood pressure but no major illnesses, aged 50 to 80, took coleus forskohlii three times per day with meals, either in root form, 1,000 mg per meal; or in root tuber form, 1,400 mg per meal.

Doctors also asked participants to reduce salt in the diet and to exercise mildly, both of which can lower blood pressure. After two months, 75 percent of those in each group showed mild improvements in blood pressure.

Coleus forskohlii has been used in Ayurvedic medicine, which is native to India, to treat heart disease, convulsions, and spasmodic pain, with the earliest references in Indian medical literature dating from about 50 B.C.
