Black Garlic – Health Benefits & Medicinal Uses

What Is Black Garlic?

Black garlic is a fermented garlic that has gained popularity recently for its unique flavor and potential health benefits. It is made by subjecting whole bulbs of fresh garlic to a specific temperature (60–90°C or 140-194°F) and humidity (70–90%) for a period of several weeks, resulting in a sweet, savory, and slightly tangy flavor that is reminiscent of balsamic vinegar and soy sauce. 

The process of making black garlic involves a series of chemical reactions that occur as the garlic is slowly fermented. The high heat and humidity create necessary conditions for converting the natural sugars and amino acids in the garlic into melanoidin, which is responsible for the black color of the garlic. This process also reduces the pungent smell of fresh garlic, making it more palatable for people who find the taste of raw garlic too strong.

Black garlic can be used in various ways in cooking and medicine. It is typically used as a seasoning for dishes such as stir-fries, marinades, and salad dressings and can also be used as a condiment on its own. In traditional medicine, black garlic is often consumed raw or as a tea or tincture.

Health Benefits Of Black Garlic

Black garlic contains a large number of antioxidants, including polyphenols and flavonoids. These compounds are known to protect the body against oxidative stress, which can lead to a range of chronic diseases, including cancer, diabetes, and heart disease.

1. Heart Health. One of the key health advantages of black garlic is its potential to improve heart health. Research has shown that black garlic can help to lower cholesterol levels, reduce blood pressure, and prevent the formation of blood clots. These effects are thought to be caused by the high levels of antioxidants and other beneficial compounds found in black garlic.
2. Anti-cancer agent. Black garlic may also have anti-cancer properties. Studies have shown that black garlic may potentially inhibit the growth and spread of cancer cells in the body and may even help prevent cancer development in the first place. In addition, it is thought that the high levels of antioxidants found in black garlic may help neutralize the free radicals that can cause cell damage and lead to cancer development.
3. Benefits for diabetic patients. Black garlic has been studied for its potential benefits in managing diabetes. Studies have shown that black garlic extract can significantly reduce blood glucose levels in rats with induced diabetes. In addition, black garlic has been found to improve insulin resistance, which is a significant contributing factor to type 2 diabetes development. The high antioxidant content of black garlic may also help protect against the oxidative stress associated with diabetes. However, further research is required to thoroughly understand the effects of black garlic on diabetes management in humans.
4. Anti-inflammatory agent. Black garlic has been shown to have anti-inflammatory properties, which may be attributed to its high levels of antioxidants. Some animal studies have found that black garlic extract can reduce inflammation in the body and may be beneficial in treating conditions such as rheumatoid arthritis and inflammatory bowel disease. Additionally, black garlic has been found to decrease the blood levels of specific inflammatory markers. A deeper understanding of the topic, however, requires more research on the anti-inflammatory effects of black garlic and its potential use as a natural remedy for inflammatory conditions in humans.
5. Liver protection. Black garlic may have protective effects on the liver due to its high levels of antioxidants. Some animal studies have found that black garlic extract can reduce liver damage caused by toxins and improve liver function. Additionally, black garlic has been found to decrease the levels of certain liver enzymes that are elevated during liver disease. However, more research is needed to completely understand the influence of black garlic on liver health in humans. While black garlic may have the potential as a natural supplement to protect liver health, it cannot be used as a substitute for medical treatment of liver disease.

Potential Medicinal Use Of Black Garlic

Black garlic has been used in traditional medicine for centuries because of its potential health benefits. In Chinese medicine, black garlic is believed to help with digestion, boost the immune system, and reduce inflammation in the body. 

However, it is important to note that black garlic should not be used as a substitute for medical treatment, and individuals should always consult with a healthcare provider before using any natural supplements or alternative treatments.

Are Black Garlic Supplements Safe To Take?

Although black garlic is generally considered safe to take, certain groups of people should exercise caution when planning to take black garlic and its supplements or avoid it altogether. For example, children, pregnant or breastfeeding women, diabetic patients, and individuals with digestive issues need to consult with the healthcare provider before starting the black garlic supplements course. In addition, people with low blood pressure, allergic reactions to garlic or other components of black garlic supplements, and those who take blood-thinning medications should avoid taking it altogether.

Conclusion

In conclusion, black garlic is a unique and flavorful ingredient that offers a range of potential health benefits. Its high levels of antioxidants, anti-inflammatory compounds, and natural antibiotics make it a valuable addition to any healthy diet. While more research is required for the full understanding of the potential health benefits of black garlic, it is clear that this fermented form of garlic is a versatile and nutritious ingredient that is well worth incorporating into your diet. Nevertheless, it is important to remember that black garlic cannot replace medical treatment, and you should talk to your doctor before taking black garlic supplements.
