Top Benefits of Garlic

Many people use garlic (Allium sativum) as a seasoning, but few realize that it has a long history of medical application, both in ancient and current times.

The onion, the rack (an Asian onion), the scallion, the chive, the leek, and the shallot are all members of the same genus as garlic, Allium. It has been utilized for thousands of years, dating back to Ancient Egypt, where it served both culinary and medicinal functions.

In this piece, we'll discuss the studies that suggest garlic may be good for your health.

Quick data on garlic

Garlic has been used medicinally for ages in several different cultures.

Raw and cooked garlic both offer potential health benefits.

There's hope that its antibacterial properties are substantial.


Many people believe that garlic has healing properties.

The history of garlic's widespread use spans millennia. The Giza pyramids were constructed around five thousand years ago, and garlic was used at the time.

According to an article by Richard S. Rivlin published in the Journal of Nutrition, the ancient Greek physician Hippocrates (approximately 460-370 BC), generally considered "the father of Western medicine," advised garlic for a wide range of ailments and illnesses. Hippocrates advocated for the use of garlic for a variety of health issues, including colds, flu, parasites, indigestion, and weariness.

Garlic may have been the earliest example of a "performance-enhancing" substance utilized in sports, as it was given to the initial Olympic competitors in Ancient Greece.

Originating in Egypt, garlic eventually made its way to the more developed Indus Valley civilizations (Pakistan and western India today). It eventually arrived in China from there.

Kew Gardens, England's royal botanical center of excellence, reports that ancient Indians viewed garlic not just for its aphrodisiacal but also its medicinal benefits. Upper-class people avoided garlic because of its offensive odor, while monks, "widows, teenagers, and those who had taken up a vow or were fasting could not eat garlic because of its stimulating character."

Garlic has been used to cure a wide variety of conditions, including bronchitis, high blood pressure, tuberculosis, liver diseases, dysentery, flatulence, colic, intestinal worms, rheumatism, diabetes, and fevers, for centuries throughout the Middle East, East Asia, and Nepal.

Garlic first arrived in the New World with the explorers from Europe.


Atherosclerosis (hardening of the arteries), high cholesterol, heart attack, coronary heart disease, and hypertension are only a few of the many blood system and heart problems for which garlic is a common treatment.

Some people nowadays also utilize garlic to ward off the onset of cancers like the lung, prostate, breast, stomach, rectal, and colon.

It should be noted, nevertheless, that not all of these applications have solid empirical support.

A study published in Food and Chemical Toxicology cautioned against briefly heating fresh raw garlic extracts since doing so diminishes their anti-inflammatory properties. It could be an issue for those who have a strong aversion to the smell and/or flavor of raw garlic.


Studies on the medicinal efficacy (or lack thereof) of garlic have been published in the following academic publications and are shown below as examples.

The danger of developing lung cancer

A study from the Jiangsu Provincial Center for Disease Control in China found that people who ate raw garlic at least twice a week during the 7-year study period had a 44% decreased chance of acquiring lung cancer.

Face-to-face interviews were conducted with 1,424 people diagnosed with lung cancer and 4,543 healthy people for the study published in Cancer Prevention Research. Questions concerning their food and lifestyle, such as how often they smoked and consumed garlic, were asked.

The study's authors concluded that a "protective connection between intake of raw garlic and lung cancer has been discovered with a dose-response pattern," implying that garlic could act as a chemo-preventive agent.

Cancer of the Brain

Researchers have discovered that the organo-sulfur chemicals in garlic can kill the cells that make up dangerous brain tumors called glioblastomas Trusted Source.

Researchers at the Medical University of South Carolina found that among three pure organo-sulfur compounds isolated from garlic (DAS, DADS, and DATS), DATS "demonstrated efficiency in killing brain cancer cells."

Research by Ray Swapan, Ph.D., and colleagues shows that chemicals derived from plants hold "great potential" as a natural therapy for slowing the growth of malignant human brain tumor cells, as stated by Swapan. Before this therapeutic approach may be used on people with brain tumors, more research is needed in animal models of these diseases.

Osteoarthritis of the hip

The prevalence of osteoarthritis was shown to be lower in women whose diets included a lot of allium vegetables.

King's College London and the University of East Anglia researchers published their findings in the medical journal BMC Musculoskeletal Disorders. Garlic, leeks, shallots, onions, and racks are all examples of allium vegetables.

In addition to highlighting the potential influence of nutrition on osteoarthritis results, the authors of the study also argued that their findings revealed the potential for harnessing chemicals that are present in garlic to develop treatments for the condition.

More than a thousand healthy female twins were studied over the course of several decades, and those whose diets included a lot of fruit and vegetables—"particularly alliums such as garlic"—had fewer symptoms of hip osteoarthritis in their early stages.

Possible effective antibiotic

A study published in the Journal of Antimicrobial Chemotherapy found that the garlic chemical diallyl sulfide was one hundred times more efficient than two commonly used medicines in combating the Campylobacter bacterium.

One of the most common causes of intestinal illnesses is the Campylobacter bacterium.

The finding is intriguing to me because it shows that this molecule has the potential to eliminate disease-causing germs in the environment and our food supply," said Dr. Xiao nan Lu, a senior author from Washington State University.

Guarding the Heart

Potential heart-healthy compounds in garlic.

Scientists at Emory University School of Medicine discovered that diallyl trisulfide, a component of garlic oil, protects the heart during cardiac surgery and in the aftermath of a heart attack. Diallyl trisulfide, they think, might also be utilized to treat heart failure.

Studies have revealed that exposure to hydrogen sulfide gas reduces the risk of heart injury.

It's a promising therapeutic, but it's a volatile molecule that poses some serious challenges in terms of administration.

This led researchers to zero in on diallyl trisulfide, a compound found in garlic oil, as a more secure delivery mechanism for hydrogen sulfide's cardioprotective effects.

Following a heart attack, the diallyl sulfide-treated mice showed 61% less damage to the at-risk region of their hearts compared to the untreated mice.

Researchers found that garlic oil may reduce the risk of cardiomyopathy in diabetics, according to a study published in the Journal of Agricultural and Food Chemistry.

Death from cardiomyopathy is the major cause of morbidity and mortality among diabetics. Thickened, inflated, and/or rigid heart muscle is the hallmark of this chronic condition.

Both garlic oil and corn oil were used to treat diabetes in experimental rats. Compared to the animal’s given maize oil, those given garlic oil showed much higher alterations consistent with protection against heart injury.

In conclusion, garlic oil has "considerable potential" for protecting hearts from diabetes-induced cardiomyopathy, the study's authors said.

Further research on humans is needed to verify these findings.

Poor diet and lack of exercise contribute to obesity, diabetes, and heart disease.

High-cholesterol patients who took garlic extract supplements were studied by researchers at Ankara University to determine their effects on blood lipid (fat) profiles. Their work appeared in the journal Nutritional Biochemistry.

Thirteen of the 23 participants also suffered from hypertension. They split up into two teams, each consisting of:

These individuals have normal blood pressure yet excessive cholesterol (normal blood pressure).

The hypertensive, high-cholesterol subset (high blood pressure).

For four months, they supplemented with garlic extract while their blood cholesterol levels, renal function, and liver health were monitored closely.

After 4 weeks, researchers said, "...garlic extract supplementation improves blood lipid profile, boosts blood antioxidant capacity, and produces significant decreases in systolic and diastolic blood pressures." It also causes a drop in the oxidation product (MDA) levels in the blood, which is indicative of fewer oxidative reactions occurring in the body.

That is to say, the hypertensive patients who took garlic extract supplements saw their blood pressure and cholesterol levels drop. The researchers noted that theirs was a preliminary study and that larger-scale investigations are required.

Caner del prostrate

Physicians in Beijing, China, at the China-Japan Friendship Hospital's Urology Department looked into the link between eating Allium vegetables and the development of prostate cancer.

They looked examined the literature up until May 2013 and published their findings in the Asian Pacific Journal of Cancer Prevention.

According to the study's findings, "Allium vegetable intake, especially garlic intake, is connected to a decreased risk of prostate cancer."

There aren’t many relevant studies, the team noted, therefore more high-quality prospective studies should be conducted.

The Damage Done to the Liver by Alcohol

Consuming excessive amounts of alcohol over a lengthy period might lead to liver damage.

Diallyl disulfide (DADS), an organosulfur molecule generated from garlic, was studied by researchers at the Institute of Toxicology, School of Public Health, Shandong University, China, to see if it would offer protection against ethanol-induced oxidative stress.

Biochemical et Biophysical Acta is where their research was published.

As a result of these findings, the researchers hypothesized that DADS could protect against ethanol-induced liver impairment.

A birth that occurs too early

Preterm birth is more likely to occur in women who have been exposed to microorganisms during pregnancy. Researchers at the Norwegian Institute of Public Health looked at the possible links between certain meals and antibiotic-resistant illnesses and premature births.

Following a review of the literature, Ronny Myhre and coworkers zeroed in on the effects of Alliums and dried fruits to reduce the likelihood of premature birth.

This study looked at the consumption of dried fruit and Alliums among 18,888 women in the Norwegian Mother and Child Cohort, of which 5% (950) experienced spontaneous PTD (preterm delivery).

"Intake of food containing antimicrobial and prebiotic ingredients may be of importance to lower the incidence of spontaneous PTD," the study's authors write. Garlic, in particular, was linked to a reduced incidence of PTD in the general population.

Curing a cold with garlic

Treatment of the Common Cold in Children and Adults was conducted by a team of researchers from St. Joseph Family Medicine Residency, Indiana, and published in American Family Physician.

As they put it, "Prophylactic use of garlic may lower incidence of colds in adults, but does not affect the duration of symptoms." To utilize it prophylactically implies doing so regularly to avoid getting sick.

There is evidence to suggest that raw garlic is most beneficial, however, studies examining the effects of consuming any amount of alliums (raw or cooked) have also found positive outcomes. Therefore, garlic's benefits can be enjoyed in several ways.
