Garlic: Does It Treat High Blood Pressure or Cause It?

In Western countries, high blood pressure, also known as hypertension, is a disease that affects around one in three adults. It often has no symptoms, but it significantly increases the risk of heart disease and stroke in a person.

A variety of unpleasant side effects are frequently caused by blood-pressure-lowering medications, which helps explain the increasing interest in potentially beneficial natural remedies, such as garlic.

Garlic’s effect on blood pressure

Garlic (Allium sativum) is a vegetable used since ancient times as a natural blood-pressure-lowering remedy.

This may be for good reason, as garlic tends to be a very powerful cure against high blood pressure, recent research indicates. In fact, it is claimed by some studies to be as efficient as standard blood-pressure-lowering drugs with far fewer side effects.

One analysis of the gold standard randomized controlled trials (RCT) stated in research that garlic supplements can reduce systolic and diastolic blood pressure (top and bottom numbers of a reading) by 6.7 and 4.8 mmHg, with no significant side effects, respectively.

Participants were given 188-2,400 mg of garlic powder supplements or aged garlic extracts per day and lasted 8-12 weeks in the studies included in the study. Several other recent reviews confirm these findings, with many showing decreases in blood pressure ranging from 2.5-11.2 mm Hg following 8-24 weeks of taking 600-2,400 mg of garlic powder a day.

It is notable that while the blood-pressure-lowering effects of garlic seem universal, they tend to be stronger in individuals with elevated blood pressure relative to those with blood pressure below the normal range.


How it works

It is thought that allicin, the main active compound in garlic, is largely responsible for the blood-pressure-lowering properties of garlic. Research suggests that allicin can prevent the development of angiotensin II by causing your blood vessels to tighten up or contract, a compound responsible for raising blood pressure.

Allicin's effects make it easier for your blood to circulate freely by blocking the production of angiotensin II, which in turn decreases your blood pressure. Allicin also tends to increase hydrogen sulfide and nitric oxide production or availability, two substances that are critical for maintaining blood pressure levels.

In addition, experts agree that the anti-inflammatory and antioxidant properties of garlic can further contribute to the ability of garlic to reduce or prevent blood pressure levels from increasing.


Safety

Garlic has been used to prevent and cure illnesses for over 5,000 years, with few records of side effects.

The bulk of studies to date show that garlic supplements are very healthy. Garlic breath, taste, or body odor are the most often recorded side effects. There is also very common stomach upset, gas, reflux, or abdominal pain, but symptoms usually remain mild.

Hypersensitivity, headaches, dry throat, coughs, hot flushes, mouth ulcers, and drowsiness can be other side effects, but these are considered uncommon. When consuming large amounts of garlic, side effects tend to be more common, and less common when supplements with garlic powder or aged garlic extracts are used.

Large intakes of garlic may interfere with certain drugs, such as those used to thin the blood, whether by diet or supplements. Talk to your healthcare provider if you are already taking medicine before dramatically raising your consumption of garlic.


To Sum It Up

A healthy and effective natural blood-pressure-lowering cure is garlic.

It can be eaten in different types, including raw garlic, garlic oil, garlic extracts from old age, and garlic powder supplements.

Before the effects are apparent, relatively large doses are required, but these treatments tend to be as effective as conventional medicines for blood pressure, with much fewer side effects. It might also be worth attempting to use garlic as a natural blood-pressure-lowering remedy.

Even before adding a garlic supplement to your routine, be sure to talk with your healthcare provider, particularly if you are taking drugs or have an underlying health condition.
