This one herb can lower pressure and sugar 20% or more
Rosmarinic acid is a natural compound found in herbs like rosemary, basil, and sage.
Animal experiments have shown that it can be very useful for metabolic problems.
For example, it improves insulin sensitivity in diabetic rats.
Researchers suspected that rosmarinic acid might also lower blood pressure.
Initial animal experiments confirmed these suspicions.
The herbal compound lowers blood pressure through effects on angiotensin-converting enzymes — similar to blood pressure lowering treatments.
The animal experiments were carried out at the Chiang Mai University in Thailand. The results were published in BMC Complementary and Alternative Medicine.
Angiotensin II is an enzyme produced in the body.
One of the effects this enzyme is to increase blood pressure.
“Angiotensin II is a potent agent that generates hypertension and oxidative stress.”
Blood pressure treatments called ACE inhibitors work by affecting this enzyme.
The treatment prevents the conversion of angiotensin I to angiotensin II — thereby lowering blood pressure.
Research suspected that some of the known effects of rosmarinic acid could lead to a decrease in angiotensin II.
To test this idea they carried out some experiments on rats.
The split 20 rats into two groups of 10.
One group of rats was given angiotensin II every day for two weeks.
“Angiotensin II was subcutaneously delivered for 14 days by implanting a pump on the back and slightly posterior to the scapulae.”
Supplemental angiotensin II was very effective at raising blood pressure.
“At the end of the study, angiotensin II increased blood pressure levels by 49–63 mmHg.”
The 10 rats in the other group were treated normally and used as a comparison group.
Two weeks in, the angiotensin II treated rats were given rosmarinic acid to see the effect of the herbal compound on blood pressure.
“Angiotensin II rats were treated with acute or chronic rosmarinic acid.”
Even a single dose of rosmarinic acid was effective at lowering blood pressure.
“Both acute and chronic rosmarinic acid treatment decreased systolic, diastolic, and mean arterial blood pressure.”
Rosmarinic acid quickly brought blood pressure down by more than 20%.
Over longer periods, the supplement led to an even greater reduction in blood pressure.
After two weeks, animals given the high dose had blood pressure close to animals which were not given angiotensin II.
The study proves that this herbal compound is effective at treating high blood pressure caused by angiotensin II.
“Rosmarinic acid would be an alternative strategy for against angiotensin II-induced hypertension and hyperglycemia.”
The researchers also discovered that the higher dose of rosmarinic acid lowered blood sugar.
“An acute 40mg/kg dose resulted in a reduction of fasting plasma glucose levels.”
Hypertension and high fasting blood sugar often occur together.
Rosmarinic acid has the ability to lower both.
“Chronic rosmarinic acid treatment reduced blood pressure and fasting plasma glucose levels.”
Previous studies showed other beneficial effects for common metabolic problems.
“Rosmarinic acid improved insulin sensitivity, preserved beta cell mass of the pancreas, increased insulin, and decreased glucose levels in diabetes.”
Safety studies on high-dose, long-term rosmarinic acid in humans need to be carried out.
“There is no safety report following chronic treatment in humans.”
But there is a lot of evidence showing that supplements are not dangerous in animals.
A previous study showed no changes in liver enzymes with chronic high-dose supplementation of the herbal compound.
“These experiments and no changes in the weight of the heart and liver of the animals.”
One human study looked at the short-term safety profile of rosmarinic acid and found it had no negative effect on key organs.
“The first randomized controlled trial study in humans reported that a single dose of rosmarinic acid is safe for blood, kidney, and liver function.”
