Garlic is a vegetable that belongs to the onion family and is also considered a herb used in cooking foods and making medicines. It is a species in the onion genus, Allium, with its close relatives including onion, shallot, leek, chive, Welsh onion, and Chinese onion.

Garlic is among the most important of the plants that are traditionally used in medicine today.

It is one of the oldest cultivated plants in the world mostly grown in Central Asia and northeastern Iran with China producing 80% of the world supply. It has long been of importance in cooking worldwide and has a long history of several thousand years of consumption and use among humans.

It boasts of a number of vital benefits. We all use garlic in our cooking without knowing its benefits.

The garlic bulb is the most commonly used portion of the plant. The bulb consists of eight to 20 teardrop-shaped cloves enclosed in white parchment-like skin.

How should you eat garlic and how much of it should you eat per day?

The best way to eat garlic is by eating it raw on an empty stomach because it contains Allicin and it is released by chewing or mincing the herb. It reduces inflammation in the body and offers antioxidant benefits. This compound, however, gets diluted during the process of cooking.

Fresh garlic also contains an amino acid called alliin. When you crush or cut the clove, an enzyme called alliinase is released.

Chew and eat two cloves first thing in the morning on an empty stomach followed by a glass of water. This will improve your digestion and appetite.

Studies have shown that the powerful antibiotic properties of garlic are most effective when eaten on an empty stomach. When you eat it before breakfast, the bacteria are exposed to its action without any obstruction by the stomach’s contents.

Alternately, you can eat one garlic clove twice a day with your meals. If you are taking its pills (supplements), the doses range from 600 to 1,200 mg per day. A typical dose is one 300 mg dried garlic powder pill two to three times a day, or 7.2 grams of aged garlic extract per day.

Allicin, the primary biologically active compound in garlic, helps in thinning the blood and reduces cholesterol levels thereby improving your cardiovascular health. Allicin also has anti-inflammatory, antioxidative, antibacterial, and anticancer properties.

The only drawback in eating it raw is its pungent taste and odor it gives to your breath. To counter this disadvantage, you can go in for its supplements. However, enteric-coated supplements will be more helpful in this regard.

If you want to give it to children, please consult your health provider.

If you have high cholesterol levels, make it a habit of eating one to two cloves with lunch or dinner.

5) Anti-allergy properties

Allergy is a manifestation of our immune system. Because of its strong antioxidant property, garlic gets rid of the free radicals, which are responsible for so many ailments.
