Aged Garlic and Other Natural Strategies Reduce Hypertension
We can now add garlic to the list of several natural strategies to reduce hypertension, or high blood pressure.
Clinical research on garlic
Researchers from Australia’s University of Adelaide confirmed that garlic is effective for reducing blood pressure.
The researchers conducted a double-blind placebo-controlled clinical trial with 79 patients who had been diagnosed with uncontrolled systolic hypertension.
The researchers divided the patients into four groups. For 12 weeks, they gave one group 240 milligrams of aged garlic extract per day in capsule form. Another group was given 480 milligrams and the third group was given 960 milligrams of the aged garlic per day.
The fourth group was given a placebo.
Before and after the three months the patients were tested for blood pressure.
The patients given the 480 milligrams per day saw a systolic blood pressure reduction of almost 12 mmHg compared with the placebo group. This reduction was greater than the reduction seen among both the 280 milligrams per day and 960 milligrams per day – which had a reduction of 7.4 mmHg in systolic blood pressure.
The researchers concluded:
“Our trial suggests aged garlic extract to be an effective and tolerable treatment in uncontrolled hypertension, and may be considered as a safe adjunct treatment to conventional antihypertensive therapy.”
What is aged garlic?
Aged garlic has either been dried in a dry storage or dried using ethanol. The natural drying process will convert its alliin and allicin content into derivatives, but it will increase its sulfur compounds – for example, S-allylcysteine, which may well provide the effective constituent in garlic’s ability to reduce hypertension.
The Australian research used an aged garlic standardized to S-allylcysteine.
Other natural strategies to reduce high blood pressure
As we’ve reported in other articles, certainly other natural strategies may also be employed for blood pressure. Here they are, summarized:
- Flaxseeds were found to reduce blood pressure in a study of 110 heart disease patients.
- Real was cinnamon proven to reduce blood pressure in multiple studies.
- Tai chi was found to reduce blood pressure in 18 clinical trials among 1371 patients.
- An 18-year study of 93,600 adult women found that those who ate fruits containing anthocyanidins and other flavonoids had a 12% lower incidence of hypertension.
- A study of 91 women found that grape seed extract reduced blood pressure. Other foods with proanthocyanidin oligomers have similar benefits.
- An international study found that forest walking reduces blood pressure.
- An alkaline diet with more vegetable protein was found the reduce blood pressure in a study that followed 1,104 kidney patients for 16 years.
- Several studies showed that Gynura herb widens and relaxes blood vessels, reducing hypertension.
- Greenfoods and Apple Cider Vinegar together with a mostly vegan diet was found to reduce blood pressure by 6 mmHg among 49 adult men in 21 days.
- A 14-year study of 2,972 elderly adults found that those who consumed the highest amounts of olive oil and rapeseed oil had significantly lower levels of blood pressure. Those consuming rapeseed oil had the lowest amounts. Other research has found that the polyphenol oleuropein a key component in this effect.
- Walnuts were found to reduce blood pressure in multiple studies.
Our reports have also found certain things increase blood pressure. These include:

He has authored 26 books on natural healing strategies. “My journey into writing about alternative medicine began about 9:30 one evening after I finished with a patient at the clinic I practiced at over a decade ago. I had just spent the last two hours explaining how diet, sleep and other lifestyle choices create health problems and how changes in these, along with certain herbal medicines and other natural strategies can radically yet safely turn our health around. As I drove home that night, I realized this knowledge should be available to more people. So I began writing about health with a mission to reach those who desperately need this information. The strategies in my books and articles are backed by scientific evidence along with wisdom handed down through traditional medicines for thousands of years.” Case connects with nature by surfing, hiking, running, biking and according to Dad, being a total beach bum.
