Black Garlic is the finished product when raw Garlic undergoes slow fermentation under strict conditions of temperature (60 degrees Celsius to 90 degrees Celsius) and humidity ranging from 80% to 90%. The fermentation time is quite long, from 30 days to 60 days. As a result, raw Garlic is fermented into Black Garlic and the content of active ingredients increases many times compared to raw Garlic when used.

It works as a special anti-oxidant medicine 5-6 times higher than raw Garlic. It helps prevent and inhibit cancer cells.

Scientists also show that, when fermenting, the groups of compounds in Black Garlic increase a lot, the sugar content increases about 13 times, fructose up to 52 times. In particular, sallyllcysteine is a powerful substance that has increased 6 times compared to the original Garlic.

  • Absorbable amino acids 311% higher
  • Carbohydrate content increased from 28.7% to 47.9%
  • Polyphenols increased from 0.08 – 0.1% to 0.5 – 2%
  • Increased levels of calcium, iron, magnesium, zinc, selenium, vitamins B1, B6
    Appearing compounds S-Allyl-S-Cysteine, Alliin, Isoalliin, Methionine, Cycloalliin, Cysteine derivatives, Tetrahydro-Β-Carboline derivatives.

In particular, the main active ingredients that make up the special effect of Black Garlic in treating diabetes are s-ally cysteine (SAC), polyphenols, diallyl disulfide and diallyl trisufide, S-ethylcysteine, S-allylcysteine, and N-acetylcysteine.

Combination of compounds: Diallyl disulfide and diallyl trisulfide, S-ethylcysteine, S-allylcysteine, and N-acetylcysteine have the effect of lowering blood pressure, lowering cholesterol, protecting LDL against oxidation and glycation…

Isoleucine in Black Garlic is a substance that creates energy and produces hemoglobin, which regulates blood sugar levels. (Hemoglobin_ is in charge of transporting oxygen in the blood).

The results of experiments to verify that Black Garlic can cure diabetes? in an animal model (in 3-week-old mice, with type 2 diabetes) showed:

  • 2 hours after drinking reduced 17.9% ~ 26.2% blood glucose index.
  • Insulin levels were significantly increased in the group of rats taking the Black Garlic extract with the two control groups.
  • Black Garlic significantly reduced serum cholesterol and triglyceride levels many times more than raw Garlic and the group that did not use Garlic.

In addition, Black Garlic also helps in the production of nitric oxide. This is a compound that plays a role in transporting oxygen in the blood, thereby reducing the pressure of blood to the vessel walls, lowering blood pressure. Adding vitamin C in Black Garlic helps to purify the blood, prevent blood clots, and effectively reduce cholesterol.

According to the research results of Akita University in Japan, if using Black Garlic continuously for 14 days, there is a significant reduction in blood pressure (up to 34.6%).

One of the main causes of cardiovascular diseases, blood fat, high blood pressure, diabetes,… is an excess of cholesterol in the body.
