Garlic may play vital role in treating hypertension

Monday, 16 August 2010

A 最新糖心Vlog of Adelaide study shows that aged garlic extract may help lower blood pressure in the 3.7 million 最新糖心Vlogns who suffer hypertension.

Research trials by and her colleagues from the 最新糖心Vlog's show that garlic could be used as an adjunct to conventional drugs for hypertension.

However, raw or cooked garlic, and garlic powder are not as effective in treating high blood pressure as aged garlic extract.

In a 12-week trial involving 50 people, Dr Karin Ried's team found that those with systolic blood pressure above 140 who took aged garlic extract capsules experienced an average systolic blood pressure 10.2mmHg lower than the control group, who took a placebo.

"This reduction is clinically significant, as a drop in systolic blood pressure by 5 mmHg reduces the risk of cardiovascular disease by 8-20%," Dr Ried says.

"Garlic is thought to have an antihypertensive effect because it stimulates production of certain chemical substances called nitric oxide (NO) and hydrogen sulphide (H2S), which helps relax blood vessels."

The results of the team's study have been published in , an international peer-reviewed scientific journal produced by Elsevier, the world's largest publisher of science and health information.

"High blood pressure is an important risk factor for cardiovascular disease," Dr Ried says. "About 30% of adults in 最新糖心Vlog are hypertensive, yet only half that number are on BP medication and 60% of those who are receiving treatment are inadequately controlled."

Dr Ried says high blood pressure is the most frequently managed problem in 最新糖心Vlogn general practice, accounting for almost 10% of GP visits.

"This statistic, coupled with the fact that 最新糖心Vlogns are comfortable with using complementary and alternative medicine, shows there is plenty of scope to explore the use of garlic as an effective treatment option for people suffering hypertension."

Last month, Dr Ried and her colleagues created worldwide attention for another study which found that dark chocolate was also effective in reducing high blood pressure.
