Because allicin is unstable, it can be easily converted into other sulfur-containing components, such as diallyl sulfur and diallyl disulfide. Most of these sulfur-containing components are important active components of garlic and have special physiological functions. Garlic essential oil contains many sulfur-containing active components formed by the transformation of allicin. For example, diallyl disulfide accounts for about 39% of the total essential oil, diallyl sulfide accounts for about 4%, and diallyl trisulfide accounts for about 365,438+0%. Many research reports show that these sulfur-containing active components have many important physiological functions for animals.
Effect on cancer
Modern scientific research shows that as early as 1957, scholars (Weisberger and Pensky) announced that garlic has an inhibitory effect on tumors. Later, many scholars used garlic or its important active components to carry out tumor cell inhibition experiments, and all achieved positive results. Many scholars have also conducted experiments on different types of cancer, and achieved good cancer suppression effects in liver cancer, kidney cancer, skin cancer, esophageal cancer, gastric cancer, colon cancer, bladder cancer, breast cancer, cervical cancer, hematological tumor diseases, lung cancer and prostate cancer. The results of these studies are great news for Taiwan Province Province, where these cancers are the highest cause of death. If all citizens can take garlic properly, I believe it will have a certain effect on reducing the probability of death from cancer.
Effects on cardiovascular diseases
In Chinese traditional dietotherapy, Compendium of Materia Medica records that garlic can deal with the problems of qi and blood stagnation and heartache, while the related dietotherapy includes garlic porridge, which has the effect of lowering blood pressure and is suitable for hypertension and arteriosclerosis, and garlic juice-pounding drink, which is used to treat hematemesis and heartache.
Modern scientific research shows that arteriosclerosis is an important factor causing cardiovascular diseases, and there are many risk factors for arteriosclerosis, such as irreversible aging, male, genetic recessive causes and other factors, as well as smoking, hypertension, obesity, hyperlipidemia, hyperglycemia and diabetes, low-concentration high-density lipoprotein, high-concentration low-density lipoprotein and very low-density lipoprotein (VLDL), blood coagulation and so on.
Many studies have shown that garlic has a significant impact on these reversible risk factors. For example, some scholars fed rabbits with garlic essential oil or raw garlic respectively, and found that their serum cholesterol content decreased after three or four months, which could reduce the incidence of arteriosclerosis; Another scholar used garlic extract to do animal experiments and fed it to rabbits. The results showed that after more than six months of experiments, the concentrations of high-density low-density lipoprotein and very low-density lipoprotein, which have adverse effects on arteriosclerosis, decreased, while the concentration of high-density lipoprotein, which is a favorable factor to reduce the incidence of arteriosclerosis, increased.
In addition, many scholars do experiments with human bodies, giving fresh garlic, fresh garlic juice or garlic powder respectively. After 3 ~ 26 weeks of different research time, it was found that the human serum cholesterol content decreased by 7.7 ~ 265,438+0.3%, which indicated that it had a certain effect on reducing the incidence of arteriosclerosis.
Effect on diabetes
Modern scientific research shows that allicin can lower blood sugar and promote the synthesis of insulin and liver sugar. Garlic essential oil resin (95%)
Ethanol extract can significantly reduce blood sugar in diabetic animals. The extract of cooked garlic can prevent hyperglycemia caused by stress.
Detoxification effect
According to Compendium of Materia Medica, garlic has the efficacy of curing pepper poison, shooting Xi Du, scorpion sting and snake sting. According to herbal records, the function of garlic is to kill insects, snakes and poisons. Related dietotherapy includes garlic boiled juice drink-treating crab poisoning; Pour garlic juice and wipe the sore.
Modern scientific research shows that garlic extract can reduce the toxicity of cyclophosphamide, a cancer treatment drug. Our laboratory also found that diallyl sulfur, diallyl disulfide and diallyl trisulfide, the important components of garlic essential oil, have positive effects on antioxidant and detoxification metabolic system in the liver at appropriate concentrations. It can also reduce the damage of aflatoxin B 1 to liver cells.
Antibacterial and insect-resistant properties
According to Compendium of Materia Medica, the application of garlic in antibacterial and insect-proof includes: back sore moxibustion, furuncle swelling, five-color erysipelas, dry and wet cholera, Shan Lan miasma, malaria, cold fever, cold malaria, diarrhea, diarrhea-forbidden, enterotoxin bleeding, ghost abdominal pain, toothache, cerebral diarrhea and sinusitis, headache and swelling pain, and infantile umbilical wind.
In the book Compendium of Materia Medica written by Wang Ang in the Qing Dynasty, it is recorded that the function of garlic is to eliminate plague, carbuncle and swelling, kill insects and snake venom. Indications: cutting moxa sticks, moxibustion for all carbuncle, malignant sore and swollen nucleus. Dietotherapy: 1 garlic, simmer hot food, treat diarrhea; Garlic and ginger syrup: garlic 15g, ginger 15g, decocted in water, and served with brown sugar to cure colds; Garlic and ginger sugar decoction: garlic 15g, brown sugar 6g, ginger l tablets, decocted in water, 3-4 times a day, to treat children's pertussis; Garlic porridge: it has the function of stopping dysentery and is suitable for acute and chronic dysentery; Eat 7 slices of raw garlic and 7 slices of cooked garlic to cure miasma in the mountains; Treatment of female vulvar swelling with washing garlic soup.
Modern scientific research shows that the water extract of garlic or its important component Joni Aho ene has antibacterial effect on fungi (such as Candida albicans). The freeze-dried water extract of garlic has antibacterial effects not only on fungi, but also on bacteria, yeast and viruses. As for insect resistance, diallyl disulfide and diallyl trisulfide, the important components of garlic, have insect repellent effect on mosquitoes; In addition, chopped garlic and n-hexane extract of garlic have insect repellent effect on carp.
From the above research results, we can know that garlic does have certain antibacterial and insect-resistant effects, so we should prevent or treat diseases or infectious diseases caused by viruses, bacteria, fungi or insects harmful to human body by eating garlic.
The function of helping digestion
Compendium of Materia Medica records that garlic can deal with the problem of customs fullness. In addition, it is recorded in Materia Medica that the function of garlic is to stimulate appetite, strengthen the spleen, dredge the five internal organs, and reach the orifices; Break the disease and melt the meat. Indications: Guan Ge is impassable. Dietotherapy: Garlic can pass through pylorus in anus, but it can't cure diseases.
Modern scientific research shows that garlic can promote the secretion of gastric juice, increase the amount of hydrochloric acid in stomach and improve the activity of proteolytic enzymes in gastric juice. At the same time, it also promotes the secretion of intestinal juice and increases the role of carbohydrate decomposing enzymes in intestinal juice, so it is helpful for digestion.
Effect of warm-up therapy
According to Compendium of Materia Medica, garlic has the effects of treating cold pain in the heart, abdominal pain caused by night crying, cold-dampness pain, eyebrow shaking and so on. Dietotherapy: soak garlic in vinegar and eat a few pieces to cure cold pain in the heart.
strengthening effect
Compendium of Materia Medica records that garlic can cure kidney qi. Modern scientific research shows that garlic can excite organs, promote blood circulation, increase metabolism and promote the secretion of male semen.
From the above introduction, we can know that eating garlic often does have many important health care effects on human body. However, how to eat garlic to achieve the health care effect? Some scholars pointed out in the paper that eating too much garlic may cause bad taste, irritation to digestive mucosa, vomiting, diarrhea, anorexia, weight loss, dysplasia, anemia, dermatitis and other side effects; Our research also shows that excessive garlic active ingredients will cause damage to liver cells, so we should eat garlic in moderation.
How much garlic to eat is the right amount, which can achieve health care effect? This is really a difficult question to answer. Based on the published research report, it is suggested that if everyone eats the following doses and types of garlic every day, it should have a positive effect on the prevention and health care of cardiovascular diseases: eating 5 grams of fresh garlic every day; Eat 0.5 ml garlic juice per kilogram of body weight every day; Eat 0.25 mg of garlic essential oil per kilogram of body weight every day; Take at least 300 milligrams of garlic powder every day.
