No matter which camp you belong to, garlic gives your body the immunity power it needs to fight certain illnesses. It is not necessary to consume raw garlic to enjoy its potential health benefits.

How garlic boosts immunity

Offers more nutrients with fewer calories

The calorie content of garlic is quite low when compared to the nutrients it contains. It is rich in vitamin C, vitamin B6, fiber and manganese. It also has traces of various other vital nutrients. All these benefits make garlic one of the best immunity booster vegetables.

Flushes harmful toxins from your body

Garlic not only contains antibacterial, antibiotic, and antiviral properties but is also known to help get rid of toxins. Allicin, a chemical found in garlic helps increase the production of white blood cells. These cells help in eliminating harmful toxins from your body. Garlic also contains a mineral called selenium that triggers liver enzymes to flush out toxins.

Boosts T cells of your body

The other reason why garlic boosts immunity is that it increases the number of T cells in your blood. These cells provide immunity by fighting viruses that can cause cold and flu. Consume garlic regularly and get rid of your cold and flu symptoms!

Acts as a stress buster

When you are stressed, you are prone to infections as your immune system becomes weak. Using garlic in such cases helps a lot as it reduces the production of stress hormones. This reduces your stress levels.

Helps lower cholesterol

Regular consumption of garlic has an effect on the cholesterol levels of your body. It reduces the total and LDL cholesterol of your body [1]. However, it does not have any significant effect on HDL or triglycerides. This way garlic helps in reducing the risk of heart ailments caused by high cholesterol.

Uses of garlic boosts immunity

The number of benefits you get from garlic depends on how you consume it. Heating it too much can deactivate some components of garlic. Here are a few ways in which you can maximize its benefits.

  • Crush or slice garlic before you eat it. This helps in activating its allicin content.

  • Let the crushed or sliced garlic stand for 10 minutes before you cook it. This helps its allicin content remain active even when you cook it.

  • If you can, use more than one clove of garlic per meal to make the most of its immunity power.

Different ways of having garlic to utilize its immunity power

Apart from cooking garlic, you can eat it in different forms. Some of these are as follows.

Garlic oil

Generally consumed in the form of capsules, garlic oil is different from garlic-flavored oil that is used in cooking. While garlic oil is prepared using a steam distillation method, garlic-flavored oil is made by infusing raw garlic in cooking oil. To make homemade garlic oil, follow the right preservation methods.


Powdered garlic is prepared by slicing and drying fresh garlic. It is processed at low heat and then put into capsules or jars. This method ensures that its allicin chemical remains intact.

Aged garlic extract

Aged garlic extract contains raw garlic that is sliced and stored in 15-20% ethanol for more than 1.5 years. This supplement does not contain allicin but has other medicinal properties of garlic.
