High blood pressure, also known as hypertension, is a common condition that affects millions of people worldwide. If left untreated, it can increase the risk of serious health problems, such as heart attack, stroke, and kidney disease. Luckily, there are natural products that can help lower blood pressure, and black garlic is one of them.

What Is Black Garlic?

Black garlic is a type of fermented garlic that has been used in traditional medicine for centuries. It is made by heating whole garlic bulbs at a high temperature and humidity levels for several weeks, causing them to turn black and develop a sweet, molasses-like flavor. Black garlic contains higher levels of antioxidants and other beneficial compounds than regular garlic, making it a popular ingredient in many health supplements and functional foods.

Black Garlic And Blood Pressure

Several studies have shown that black garlic can help lower blood pressure in people with hypertension. One study found that taking black garlic extract for 12 weeks significantly decreased both systolic and diastolic blood pressure in hypertensive patients. Another study showed that black garlic extract improved endothelial function, which is the ability of the blood vessels to dilate and relax, in patients with hypertension.

So, how does black garlic lower blood pressure? One possible mechanism is through its ability to increase nitric oxide dependent dilation of blood vessels, and, as a result, improve blood flow [3]. Nitric oxide also helps reduce inflammation and oxidative stress, both of which can contribute to high blood pressure. Black garlic is also rich in other compounds, such as S-allyl cysteine, that have been shown to have blood pressure-lowering effects [1].

Other Health Benefits of Black Garlic

In addition to its blood pressure-lowering effects, black garlic has other health benefits. For example, it may help improve cholesterol levels [4], reduce inflammation [5], and boost the immune system [6]. Some studies have even suggested that black garlic may have anticancer properties, although more research is needed to confirm this.

How to Incorporate Black Garlic Into Your Diet?

Black garlic is available as a supplement, but can also be used in cooking in its whole form. Its unique flavor makes it a great addition to sauces, salad dressings, and marinades. Additionally, you can use it instead of regular garlic in your favorite recipes. Among black garlic products are black garlic oil, which can be used as a cooking oil or a seasoning for salads and vegetables.

Are Black Garlic Supplements Safe?

Generally, black garlic is considered to be safe for most people to consume in raw form and as a supplement. However, as with any superfood, it is advisable to consult your doctor before making black garlic a part of your diet.

People who should be especially cautious about using black garlic and black garlic supplements are:

  • pregnant and breastfeeding women
  • children
  • people who take blood-thinning medications
  • patients with chronic bleeding disorders
  • people after surgery or those preparing for the surgery
  • people with an allergic reaction to garlic or any other component of the supplement
  • people with diabetes
  • people suffering from stomach or digestive issues
  • individuals with low blood pressure

In addition, black garlic may interact with some medications. Therefore, even if you don’t fall into the groups of people listed above, we recommend discussing black garlic with your healthcare provider prior to trying it.


Black garlic is a natural remedy with the potential to help lower blood pressure and improve overall health. Its unique and complex flavor makes it a great addition to any diet, while its numerous health benefits make it a supplement to consider. If you’re interested in trying black garlic, talk to your doctor to determine if it’s suitable for you.
