Garlic is a bulbous plant that belongs to the Allium family, closely related to onions, shallots, leeks, and chives. Each garlic bulb, or head, is made up of multiple segments known as cloves. These cloves are encased in a paper-like sheath. Garlic has been used for thousands of years both for culinary and medicinal purposes. Revered for its distinctive pungent aroma and robust flavor, garlic adds depth to a myriad of dishes. Beyond the kitchen, garlic has also been touted for its potential health benefits, which include antimicrobial and antioxidant properties, among others.
Types of Garlic
There are various types of garlic, each with its unique flavor profile, appearance, and uses. Here’s a look at some of them:
a. Hardneck Garlic: This variety produces a stiff stem, or “neck,” and typically yields fewer cloves than softneck varieties, but the cloves are larger. Hardneck garlic often has a more intense flavor. It also produces scapes, which are flower stalks that can be harvested and consumed.
b. Softneck Garlic: This is the type of garlic most commonly found in grocery stores. It’s known for its soft, pliable stalk that’s suitable for braiding. Softneck garlic often has a milder flavor compared to hardneck and is generally easier to grow in a variety of climates.
c. Elephant Garlic: Despite its name, elephant garlic is not a true garlic but rather a variant of the leek. It’s named for its size, as it produces exceptionally large bulbs and has a milder taste, almost reminiscent of onions.
d. Creole Garlic: A subtype of hardneck garlic, Creole garlic has beautiful rose or purplish-hued cloves. It’s known for its spicy kick and is especially popular in warm climates.
e. Rocambole Garlic: Another hardneck variety, Rocambole garlic is renowned among garlic enthusiasts for its deep, complex flavor profile. Its cloves are usually easy to peel.
f. Black Garlic: This isn’t a distinct variety but rather a preparation of garlic. Regular garlic bulbs are aged under specific high-heat conditions, turning the cloves black, soft, and sweet. The taste is reminiscent of a mix between balsamic vinegar, molasses, and tamarind, with all the sharpness of raw garlic removed.
Uses of a Garlic

Health benefits of Garlic
Garlic has been esteemed for centuries not only for its rich flavors but also for its potential health benefits. Scientific research has looked into many of these claims, and while not all are conclusively proven, there’s promising evidence for several of them. Here are some of the health benefits associated with consuming garlic:
Cardiovascular Health
Lowers Blood Pressure: Allicin, a compound found in garlic, has been linked to reduced blood pressure in people with hypertension.
Reduces Cholesterol: Regular garlic consumption may help reduce LDL cholesterol levels, thereby potentially decreasing the risk of heart disease.
Antioxidant Properties: Garlic is rich in antioxidants that can help protect against oxidative damage, a major factor in the aging process and many diseases, including heart disease.
Antimicrobial Effects
Garlic has natural antibacterial, antiviral, and antifungal properties. This makes it a popular remedy for minor infections, and it’s also studied for its potential to combat more severe infections.
Boosts Immune Function
Regular garlic consumption might help fortify the body’s defenses against common colds and other illnesses.
Cancer Prevention
Some studies have suggested that garlic consumption may be linked to a reduced risk of certain cancers, especially stomach and colorectal cancers. This might be due to its antioxidant properties and its ability to boost the immune system.
Blood Sugar Regulation
There’s preliminary evidence that garlic might help regulate blood sugar levels, making it of potential interest for diabetics or those at risk for diabetes.
Bone Health
Some research in rodents has shown that garlic can minimize bone loss by increasing estrogen levels in females. However, more research in humans is needed.
Digestive Health
Garlic can play a role in gut health by promoting the growth of beneficial bacteria and suppressing harmful bacteria.
Detoxification
High doses of garlic supplements have been shown to support the body’s protective mechanisms against heavy metal toxicity.
Improves Skin Health
Due to its antioxidant properties, garlic might help in skin protection against UV rays and thus delay the aging process.
Anti-inflammatory Properties
Garlic has compounds that have been found to have anti-inflammatory effects, which can be beneficial in conditions like arthritis.
While these potential benefits are promising, it’s crucial to remember that garlic isn’t a cure-all. Consuming garlic as part of a balanced diet can be beneficial, but relying on it alone to treat or prevent diseases may not be effective. Moreover, garlic can interact with certain medications and can cause digestive discomfort when consumed in large amounts. Always consult with a healthcare professional when considering garlic for specific health concerns.
Disadvantages of a Garlic
While garlic is renowned for its culinary and health benefits, there are certain disadvantages or side effects associated with its consumption:
Bad Breath & Body Odor: Perhaps the most commonly known drawback of eating garlic is the persistent odor it can impart to one’s breath. Moreover, for some individuals, consuming a lot of garlic can also lead to an evident body odor.
Digestive Issues: Consuming large amounts of garlic, especially on an empty stomach, can lead to digestive issues such as gas, bloating, heartburn, and stomach upset.
Risk of Bleeding: Garlic acts as a natural blood thinner, which means it can increase the risk of bleeding. This is especially important for those undergoing surgery or taking blood-thinning medications.
Low Blood Pressure: While garlic can help lower blood pressure, it might cause problems if one already has low blood pressure or is taking medication to control hypertension.
Allergies: Some people might have an allergic reaction to garlic. Symptoms of a garlic allergy include skin rash, eczema, fever, headache, or even anaphylaxis in severe cases.
Drug Interactions: Garlic can interfere with certain medications, including anticoagulants, drugs used for HIV/AIDS, and some drugs used to treat tuberculosis.
Skin Irritation: Raw garlic, when applied directly to the skin, can cause burns or irritations, especially in sensitive individuals.
Aggravate IBS: For those with Irritable Bowel Syndrome (IBS) or sensitive digestive systems, garlic can exacerbate symptoms because it’s high in FODMAPs (Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols).
Risk During Pregnancy: Excessive consumption of garlic might not be safe for pregnant women as it could stimulate the uterus or lead to other complications.
Potential Toxicity: Consuming an exorbitant amount of garlic in a short time span might lead to toxicity, though such instances are rare.
It’s crucial to balance garlic intake with the potential risks. For most individuals, consuming garlic as part of a varied diet won’t cause problems. However, if you have specific health concerns or take medications, it’s a good idea to consult with a healthcare professional about the amount of garlic that’s safe for you to consume.
