There is an important ingredient in garlic - allicin. Allicin is a pure natural bactericidal substance. Even if diluted 100000 times, this kind of allicin can still kill typhoid bacillus, Shigella, influenza virus, etc. in an instant, especially Helicobacter pylori, the primary inducer of gastric cancer. In addition, allicin also has anti-tumor effects, which can improve cellular immunity, humoral immunity and non-specific immune functions, effectively expel lead accumulated in the body, reduce total cholesterol in plasma, reduce blood pressure, inhibit platelet activity, reduce hematocrit, and reduce blood viscosity. In addition, allicin also has the functions of removing dandruff, anti itching, and preventing nerve   Pain, treatment of mercury poisoning, anti radiation, anti-oxidation, protection of biofilm, anti-aging, prevention of mosquito bites, anti cold and other health care functions. However, allicin only exists in raw garlic. When garlic is fried or boiled, most of the allicin in it will volatilize or be decomposed by heat, which greatly reduces the health care efficacy of garlic. Therefore, garlic should be eaten raw as much as possible. If you really can't stand the spicy taste of garlic, you can sprinkle minced garlic when the cooking is about to come out of the pot. In this way, the spicy taste will be weakened and the allicin will not be lost too much. In addition, you can't eat allicin when you eat garlic as a whole, because allicin doesn't exist directly, but is synthesized by two substances, allicin and alliinase, which exist independently in garlic. Only when you beat or mash garlic can they be combined into allicin. So when eating garlic, you'd better smash or mash it, or chew it for a while, which will also help eliminate oral bacteria.

   AllicinAlthough it is good, raw garlic should not be eaten too much. The first is eye disease patients. The ancients said, "garlic is the only way to cure all diseases.". Long term and large amount of garlic is harmful to eyes. Ji Kang said in health preserving theory that "meat is pungent and harmful to the eyes". Garlic tastes the most pungent. Moreover, it clears the orifices and clears the eyes, which is easy to cause eye damage. Therefore, you should pay attention not to eat too much garlic, especially for people with eye diseases. You must avoid spicy food during treatment. Secondly, those who are weak and hot should not eat raw garlic. The ancients believed that eating more garlic would consume people's Qi and blood. According to the records of "herbal rejuvenation", garlic is pungent and hot and toxic, causing phlegm and hot work, and dissipating Qi consumes blood. People who are weak and hot should not touch their lips. ". So people with poor health and weak Qi and blood should pay attention. Moreover, for patients with diarrhea due to spleen deficiency, raw garlic is very irritating, so eating less can promote digestion. However, if you eat garlic when suffering from non bacterial enteritis and diarrhea, strong stimulation will aggravate congestion and edema of intestinal mucosa, promote exudation, and worsen the condition. In addition, people who are seriously ill should eat with caution. Garlic is a hair substance. The so-called hair substance refers to the food that is particularly easy to induce certain diseases or aggravate the diseases that have occurred. Eating spicy foods such as garlic and pepper is likely to have obvious side effects for people who are seriously ill or taking medicine, which may not only cause old diseases, but also make the drugs ineffective, or have a chain reaction with the drugs, affecting their health. Finally, it should be emphasized that allicin also has a certain effect on the reproductive system. Allicin has an inhibitory effect on the sperm of rats, voles and humans. The degree of spermicity inhibition is related to the concentration of the drug. No morphological changes were found in the killed spermatozoa. The inhalation of this drug in male rats did not interfere with normal spermatogenesis, and the effect was better than that of gossypol. At the same time, it has no stimulating effect on the vagina at the effective concentration of spermicity inhibition, and does not inhibit the growth and reproduction of Lactobacillus. It will neither cause local adverse reactions nor interfere with the normal flora of the vagina.

        There is a saying: garlic has many benefits, but only one harm hurts the eyes. Long term excessive consumption of garlic will lead to blurred vision, decreased vision, tinnitus, dry mouth, top heavy, and decreased memory. Therefore, we should pay attention to a "degree" in everything. Scientists believe that it is appropriate to eat one clove of raw garlic every day. If you eat two or three cloves of cooked garlic, it is enough. Although garlic is small, it is useless to eat more.
