 Likes  Comments

Benefits of garlic oil include its ability to aid in weight loss efforts, soothe headaches, reduce inflammation, stimulate circulation, optimize digestion, and boost cognitive function and the immune system. Other benefits include relief from congestion, lower cholesterol levels and normal blood sugar levels. There are also some notable side effects of using garlic oil such as excess bleeding, gastrointestinal distress, allergic reactions, skin inflammation, and bad breath. Some of these side effects are unavoidable, while others usually affect people who are using an excessive amount of garlic oil or they have pre-existing conditions that interact poorly with garlic oil.

What is Garlic Oil?

Garlic oil is made through steam distillation of fresh garlic cloves or by soaking the cloves in a carrier oil and allowing the active components of the garlic to be leeched into the oil. Garlic is scientifically known as Allium sativum, and is known as one of the healthiest foods you can add to your diet. Garlic oil can be used in culinary applications, and is also widely applied in natural medicine practices. The oil is also widely available in oral tablet or capsule form, although this delivers a far less concentrated dose of garlic’s active ingredients. The majority of the health benefits acquired through garlic oil is attributed to its high content of allicin, sulfide compounds, key amino acids and enzymes, as well as ajoene and other antioxidant compounds.

Benefits of Garlic Oil 

Using garlic oil is popular for people struggling with obesity, metabolic disorders, diabetes, high blood pressure, indigestion, a weak immune system, anemia, arthritis, a weak immune system, congestion, cold, flu, headaches, diarrhea, constipation and poor nutrient uptake, among others.

Improves Digestion

Garlic juice can be a very effective remedy for constipation and inflammation in the gut, given its high antioxidant content and stimulating nature. It can help improve digestion and stimulate peristaltic motion, and even reduce the risk of various gastrointestinal cancers. 

Reduces Inflammation

Allicin found in significant levels in garlic oil makes it valuable for topical remedies and internal use for soothing inflammatory conditions. Allicin is a very powerful antioxidant and anti-inflammatory compound that can ease tissue irritation and reduce pain in joints and localized areas.

Treats Metabolic Disorder

Many people use garlic oil for the treatment of metabolic syndrome, which tends to be accompanied by high blood pressure, high blood sugar, high cholesterol and obesity. The antioxidants in this oil can directly impact this syndrome, lessening all of those risk factors and optimizing metabolic activity.

Relieves Headaches

Anecdotal evidence suggests that applying small amounts of garlic oil to the temples, or consuming a small amount of this concentrated oil, can quickly relieve inflammation in the temples and capillaries. This may reduce the occurrence of migraines and headaches. 

Has Powerful Antioxidants 

Allicin is not only one of the most versatile and powerful antioxidants that we know of, but is also found in extremely high concentration in garlic oil. If you are trying to decrease oxidative stress, lower your risk of cancer, or prevent premature aging, use of this oil is highly recommended. 

Regulates Diabetes

The hypoglycemic nature of garlic oil is well known, as it can help to regulate insulin production and energy consumption by the body. This oil is ideal for optimizing metabolic activity, and can help prevent the glucose spikes and drops that plague so many diabetic patients. 

Prevents Obesity

Use of garlic oil is known to kick-start the metabolism, which equates to passive fat burning, in addition to the cholesterol-lowering power of this oil. Garlic can also help to suppress the appetite, while the sulfide compounds can create a feeling of fullness, which will reduce overeating and snacking between meals.

Maintains Respiratory Health

Inhaling garlic oil, similar to eating garlic, can quickly clear the sinuses and relieve pressure. Beyond that, however, garlic oil can also reduce allergic sensitivity, helping to minimize asthmatic episodes and clear congestion. 

Strengthens Immune System

Not only is garlic oil packed with antioxidants but it also has clear antibacterial, antiviral, anti-fungal and antiseptic properties. This makes it ideal for treating topical ailments on the skin, while also boosting digestive health and wipe out bacterial infections growing in your gut.

Stimulates Nutrient Uptake 

The sulfide compounds and antioxidants found in garlic oil can stimulate more efficient nutrient uptake in the digestive system, including the absorption of calcium, iron and potassium. For people struggling with anemia or other nutrient deficiencies, garlic oil is an excellent base for their diet. 

How Do You Make Garlic Oil?

Some people choose to make their own garlic oil, as all you need is fresh garlic cloves and a carrier oil – typically olive oil or another vegetable oil. Commercial version of this oil is often produced through a cold-pressing process, however, the at-home version is much easier to prepare. This potent natural oil can also be used in culinary and medicinal applications.



  • 8 fresh garlic cloves
  • 2 cups of extra virgin olive oil

Step 1 – Crush the garlic cloves and remove the skin.

Step 2 – Add garlic cloves to a mason jar and add olive oil.

Step 3 – Shake vigorously and then seal the jar.

Step 4 – Refrigerate the mixture for 4 days.

Step 5 – Strain out the garlic cloves and store resulting oil in a cool, dark and dry place.

Garlic Oil Side Effects

This powerful natural oil does come along with certain side effects, including dangerously low blood pressure and blood sugar, stomach issues, skin inflammation, excess bleeding, body odor and bad breath. Responsible use of this oil, after consulting with your doctor, can often help you avoid the more serious side effects of this oil.


The active ingredients in garlic oil do have anticoagulant effects, which may be dangerous for people on blood-thinners, or those who are preparing for surgery in the near future.

  • Heart Problems – This oil’s proven effect on metabolic disorders, including the drop in blood pressure and cholesterol, can cause dangerous levels of hypotension if taken in conjunction with blood pressure-lowering medications.
  • Odor Issues – Garlic is legendary for its potent smell, which can affect breath and body odor, as the aromatic compounds can emerge in one’s sweat. If you consume an excessive amount of garlic oil, you may experience bad breath and body odor, but this is a difficult side effect to avoid.
  • Skin Irritation – Due to the highly concentrated nature of the active ingredients of garlic oil, it is known to cause skin redness, irritation, swelling and even hives when topically applied. This is more likely in people who are allergic to garlic, but can also occur in people with sensitive skin.
  • Gastrointestinal Distress – When consumed in excessive amounts, garlic oil can have powerful effects on the gastrointestinal system, including diarrhea, cramping, bloating, vomiting, gas and heartburn. If you experience these side effects to a serious degree, discontinue use immediately and speak to your doctor about other options for less potent oils.
