Garlic Tea: Benefits, How to Make & Side Effects

Garlic tea may help relieve cough, flu, and cold symptoms. It is also commonly used to support the immune system and may help lower LDL cholesterol and support healthy blood pressure, as garlic contains antioxidant and bioactive compounds.

This tea may also support weight loss because garlic has a mild thermogenic effect that can increase energy expenditure. However, it should be considered a supportive measure and not a standalone treatment for overweight or obesity.

Garlic tea should be prepared with crushed garlic so the enzyme alliinase can convert alliin into allicin, one of garlic’s main active components. You can also add lemon, honey, or ginger to improve the flavor and enhance the recipe.

Main benefits

Garlic tea has many potential benefits, and may help:

1. Fight flu and colds

Garlic tea is rich in allicin, a sulfur compound with immune-supporting properties that may help the body fight flu and colds and shorten how long symptoms last.

2. Strengthen the immune system

In addition to allicin, garlic tea also contains vitamin C. Together, these compounds have antioxidant effects that may help support the immune system and help the body fight viruses, bacteria, and fungi.

3. Relieve cough

Garlic tea has expectorant properties that may help relieve cough by making mucus thinner and easier to clear.

It also has anti-inflammatory properties that may help reduce inflammation in the lungs.

4. Control high blood pressure

Garlic tea may help control mild to moderate high blood pressure because it has a vasodilating effect. In other words, it may help widen blood vessels and improve blood flow, which can help lower blood pressure.

5. Lower cholesterol

Garlic tea has antioxidant and lipid-lowering effects that may help reduce bad LDL ("bad") cholesterol and triglycerides by limiting oxidation.

According to the CDC, high levels of LDL cholesterol can lead to plaque buildup in the arteries and increase the risk of heart disease and stroke. 

6. Prevent cardiovascular disease

Allicin in garlic tea has strong antioxidant effects that may help reduce LDL (“bad”) cholesterol and triglycerides, which can contribute to plaque buildup in the arteries.

Garlic tea may also help lower blood pressure and reduce platelet aggregation, which can help prevent clots from forming inside blood vessels. According to the American Heart Association, uncontrolled high blood pressure can increase the risk of heart attack and stroke.

As a result, this tea may help reduce the risk of cardiovascular diseases such as atherosclerosis, heart attack, and stroke.

7. Support weight loss

The allicin in garlic tea may also help support weight loss because it is a thermogenic food that may help speed up body fat burning.

For this reason, garlic tea may be used as a supportive option in the treatment of overweight and obesity.

8. Support wound healing

Garlic tea may help support the healing of skin wounds because it has anti-inflammatory, antiseptic, and antimicrobial effects.

When applied to the skin, it may help speed up the formation of new tissue and improve blood flow in the area.

9. Prevent premature aging

Garlic tea may also help prevent premature skin aging because the vitamin C and allicin it contains have antioxidant effects that help protect cells from damage caused by free radicals.

10. Control diabetes

Garlic tea may also help support control of type 2 diabetes because it may help lower blood sugar levels when consumed before meals.

For this reason, this tea may be used alongside the conventional treatment recommended by a healthcare provider.
