| Raw Garlic: Properties, Health Benefits, and How to Consume It Safely |
But what exactly are the properties of fresh, raw garlic? How should it be consumed to maximize its positive effects? And are there any risks or contraindications to eating garlic raw? Let’s take a closer look.
What Is Garlic?
Garlic (Allium sativum) is a perennial herbaceous plant from the Alliaceae family, which also includes onions, shallots, chives, scallions, and leeks. The garlic bulb (head) is made up of cloves, known for their strong aroma and pungent taste, making them popular as a seasoning.
There are many varieties of garlic, including white garlic, black garlic, purple garlic, and wild garlic. According to Larousse, garlic owes its natural antibiotic properties to compounds such as garlicin and allicin, and it also has a blood pressure–lowering effect.
Cooked or Raw: Garlic’s Health Benefits
Garlic has been praised for decades for its many health benefits. It is known to be:
Antimicrobial
Antioxidant
Beneficial for the immune system
Helpful in managing blood pressure and cholesterol
Garlic consumption has been associated with reductions in cholesterol and triglyceride levels, as well as a lower risk of cardiovascular disease and certain cancers.
The garlic bulb is also rich in minerals and is an excellent source of:
Manganese
Phosphorus
Selenium
Copper
This explains why garlic plays a central role in many culinary traditions worldwide. However, the way garlic is consumed matters, and raw garlic appears to be the most effective form.

Why Is Raw Garlic Good for Your Health?
Fresh herbs and spices generally contain higher antioxidant levels than dried or processed versions—and garlic is no exception. Raw garlic is estimated to be 1.5 times more powerful than garlic powder or dried garlic.
To maximize its benefits, experts recommend crushing or chopping garlic cloves and letting them rest for 10 to 15 minutes before consumption, according to Eating Well.
Allicin: The Key Active Compound in Garlic
This resting time allows two enzymes—alliin and alliinase—to interact and trigger the formation of allicin, a powerful antioxidant. Research shows that many of garlic’s beneficial compounds are reduced or destroyed by heat.
High cooking temperatures deactivate alliinase, preventing allicin formation and significantly lowering garlic’s antioxidant potential.
To preserve its health benefits:
Consume garlic raw, for example in salad dressings
Or add it at the end of cooking
For those who dislike raw garlic, crushing it and letting it rest before cooking can still help retain some of its beneficial properties. Just don’t forget your toothbrush—raw garlic is notorious for causing bad breath!
Eating Raw Garlic: Risks and Contraindications
When consumed in large amounts—especially on an empty stomach—raw garlic may cause:
Stomach burning and pain
Gas and bloating
Nausea or vomiting
Recommended Daily Intake
To protect digestive health, adults are generally advised not to exceed 4 grams per day, which corresponds to about one clove of garlic.
Eating raw garlic is generally safe, unless you suffer from blood or metabolic disorders. In such cases, it is recommended to consult a healthcare professional before consuming more than one clove per day.
Conclusion
Raw garlic is a nutrient-dense food with scientifically supported health benefits, particularly due to its antioxidant and antimicrobial properties. Consumed correctly and in moderation, it can support cardiovascular health, immunity, and overall well-being.
However, like any natural remedy, garlic should be used wisely and in appropriate amounts, especially for individuals with underlying medical conditions. When in doubt, medical advice is always recommended.
