Garlic (Allium sativum) belongs to the same family as leeks, chives, onions and shallots. The fragant garlic has a long history of being used both for food and for its alleged medical properties. Sankrit records from 5,000 years ago includes references to the use of garlic remedies.
During both World War I and World War II, garlic was used as an antiseptic to prevent gangrene in wounds. During WWI, it was also used to combat the dysentery that spread due to poor sanitary conditions in the trenches and impure water collected from shell-holes or other cavities.
USDA nutrient profile
A typical serving of one or a few cloves will not provide you with any significant amounts of carbohydrates, fat, protein, vitamins or minerals. The table below is for 100 gram of garlic, and it is unusual to eat that much in one sitting.
|Nutritional value per 100 g of raw garlic|
|Dietary fiber||2.1 g|
|Pantothenic acid (B5)||(12%)
|Percentages are roughly approximated using US recommendations for adults.|
Many of the alleged health-promoting effects of garlic is believed to be due to allicin. Allicin is the sulphur-containing compound that gives garlic its distinctive taste and odor. The plant produces this compound as a defense against attacks. When fresh garlic is chopped or crushed, the enzyme alliinase converts alliin into allicin.
In laboratory studies, allicin has displayed numerous antimicrobial properties. It is currently being investigated as a potential weapon against methicillin-resistant Staphylococcus aureus (MRSA), since previous studies have yielded promising results, even for strains of MRSA that are resistant to may other commonly utilized chemical agents.
Garlic and cardiovascular health
A 2007 meta-analysis showed that garlic preparations are superior to placebo in reducing blood pressure in individuals with hypertension. This is due to garlics ability to widen blood vessels.
A 2013 meta-analysis showed that garlic can lower total cholesterol in adults with high cholesterol if taken for longer than two months.
Garlic and cancer
A 2014 meta-analysis of studies carried out in Korea showed that garlic consumption was associated with a lower risk of stomach cancer.
Garlic as an anticoagulant
Garlic can reduce platelet aggregation. If you are using an anticoagulant drug, you should keep your garlic intake low.
Of course, there are situations where garlic’s ability to reduce platelet aggregation would be desirable. Reduced platelet aggregation means that blood clots are less likely to form. It is therefore possible that a diet rich in garlic could reduce the risk of heart attacks and other serious blood clots.

Other members of the Allium genus in the UK
In the United Kingdom, you can find at least three Allium species in the wild:
- Wild garlic (Allium ursinum)
- Crow garlic (Allium vineale )
- Field garlic ( Allium oleraceum)
In North America, the names Wild garlic and Crow garlic typically refers to Allium vineale instead.
