Key Medicinal Uses for Garlic

Cholesterol Management: Did you know that Garlic lowers LDL cholesterol while maintaining HDL cholesterol and triglycerides. There are dozens of studies showing the many cardiovascular benefits of taking Garlic. This herb also reduces oxidation of fat and cholesterol which is the first step of atherosclerosis.

Blood Pressure: Garlic thins out the blood, reduces clotting and lowers blood pressure. It also acts as a regulator for the circulatory system, warming the whole body, reducing thrombosis and varicose veins.

Cold & Flu Symptoms: Garlic has antibacterial properties, making it a popular remedy for helping manage the symptoms of cold and flu. Garlic also enhances the body’s immunity & helps remove pathogens. (Pole, S.)

Lungs: Garlic is a strong decongestant, and the volatile oils help cleanse bronchioles. Also it helps clear wet and sticky mucus, encouraging the unrestricted flow of breath. (Pole, S.)

Fungal Skin Infections: Garlic can be made into a paste or infused into an oil and applied to the skin topically for fungal skin infections, ringworm, ear infections. (Pole, S.)

Biomedical Actions

Carminative, Vermifuge, Vasodilator, Expectorant, Anticholesterol, Anti-Microbial, Antibacterial, Antifungal

Garlic Constituents

  • Organosulfur compounds - alliin (which converts to allicin in the presence of Allinase)

  • Allinase

  • B Vitamins

  • Minerals

  • Flavonoids

Garlic Contraindications

  • Avoid medicinal doses in pregnancy (culinary use is fine) - may be too stimulating for the fetus (fine during lactation) (Pole, S.)

  • Avoid with high pitta - hyper-acidity, high blood pressure from heat, ulcers. (Pole, S.)

  • Caution taking with anti-clotting / anti-platelet medications as it can exacerbate anti-clotting properties. (Pole, S.) Garlic may potentiate the activity of anticoagulant medications such as aspirin. (Hoffman, D.)

  • In high doses, Garlic may irritate the gut lining and cause nausea, burning of the mouth, diarrhea and vomiting. Contact dermatitis has also been noted as a risk when handling this herb for some people. (Hoffman, D.)

Garlic Dose

Include 1-3 cloves daily or 6-15g dried (Pole, S.). Garlic is a pretty mild herb and is safe as long as you have no allergies to alliums. All alliums have similar properties - onion shallot chives etc. I always try to consume organic and regionally-grown produce wherever possible.

Garlic Essential Oil

Garlic essential oil can be taken internally at doses of up to 120mg per day (equivalent to about 60g fresh garlic) over a period of 3 months without any adverse effects. (Hoffman, D.)

Dosage for Garlic Extracts

An extract is a more concentrated form of an herb that is often labeled to contain certain “marker compounds” that modern science has deemed to be the main medicinally beneficial constituent. Unfortunately, this is not always a great thing (ex. St John’s Wort extract, Ashwagandha root extract). However, in the case of Garlic, I have seen extracts work quite well.

Standardized garlic extracts usually specify their allicin content, which can range from 1.3% to 1.5% of the extract. Generally, for standardized garlic extract, the typical dosage ranges from 600 to 1,200 milligrams per day, often divided into two or three doses.

    • Increased Body Heat: Feeling excessively warm or hot.

    • Inflammation: Redness, rashes, or skin irritations.

    • Digestive Issues: Acid reflux, heartburn, and loose stools.

    • Oily Skin: Acne and other skin problems.

    • Sharp Appetite: Frequent hunger and craving spicy foods.

    • Red Eyes: Bloodshot or sensitive eyes.

    • Irritability and Anger: Quick to anger and impatience.

    • Perfectionism: High standards and frustration.

    • Competitive Nature: Strong ambition and competitiveness.

    • Aggressiveness: Confrontational behavior in stress.
