First, strengthen the role of the immune system and prevent colds.

The fat-soluble volatile oil in garlic can significantly improve the phagocytosis of macrophages, enhance the immune system, enhance physical strength, eliminate fatigue and prevent colds. After people enter middle age, the number of immune cells is reduced, their vitality is weakened, and their immunity is reduced, so they are easily invaded by external germs, leading to physical decline and diseases. The active components in garlic extract can stimulate immune cells, make them more active and conscientious, and strictly "check" all abnormal substances, bacteria and viruses mixed into the body; It can also stimulate and regulate the growth of immune cells. Eating garlic or taking garlic products for a long time can maintain a strong "immune cell team" in the body to resist foreign invasion.

Second, prevent arteriosclerosis and cardiovascular and cerebrovascular diseases.

1, the active substances in garlic extract can control the synthesis of low-density lipoprotein (bad cholesterol) and triglyceride, and increase high-density lipoprotein (good cholesterol) in blood, thus reducing blood lipid. Once the low-density lipoprotein in blood is "oxidized" by free radicals, it will penetrate into the blood vessel wall, accelerate the formation of atherosclerotic plaques, slow down the blood flow, and make blood easy to agglutinate, leading to ischemia and hypoxia in the heart, brain and other tissues, which will affect health. High-density lipoprotein can remove excessive cholesterol and low-density lipoprotein in blood and cells, and transport lipid plaques deposited on blood vessel walls to the liver for transformation.

Third, prevent cancer. The proverb says, "Garlic is a treasure, and it has a good anticancer effect". Garlic can prevent the synthesis of carcinogens and reduce the growth of cancer cells.
