7 Health Benefits of Garlic

Most drugs and medications are derived from herbs and foods, many of which have been used traditionally for centuries. Among them, garlic stands out as a powerhouse of medicinal value. Known historically as “Russian Penicillin,” garlic contains allicin—a potent compound shown to help fight bacteria, viruses, fungi, and colds while strengthening the immune system.

Here are 7 scientifically backed health benefits of garlic:

1. Prevents the Common Cold

   A 12-week study in Advances in Therapy showed that people taking allicin supplements had 63% fewer colds and recovered faster than those on placebo.

2. Treats Recurrent Hair Loss

   According to the Indian Journal of Dermatology, applying garlic gel to the scalp alongside steroid cream significantly improved hair regrowth.

3. Detoxifies Heavy Metals

   In a Basic Clinical Toxicology study, workers with chronic lead poisoning who took garlic had reduced symptoms compared to those given d-penicillamine, a pharmaceutical drug.

4. Prevents Hip Arthritis

   Research in Musculoskeletal Disorders found that sulfur-rich vegetables like garlic may help prevent the development of osteoarthritis, particularly in the hips.

5. Lowers Blood Pressure

   In Maturitas, patients with uncontrolled high blood pressure saw improvements after taking aged garlic extract for 12 weeks.

6. Enhances Exercise Tolerance

   The Indian Journal of Physiology reported improved heart rate and endurance in heart disease patients who took garlic oil capsules over six weeks.

7. Reduces Lung Cancer Risk by 44%

   In a 7-year Chinese study (Cancer Prevention Research), people who ate raw garlic at least twice a week had a 44% lower risk of developing lung cancer—even among smokers.

How to Take Garlic:

Garlic is most potent when eaten raw. You can incorporate it into salsa, salad dressings, pasta sauce, mashed potatoes, or even smoothies. For those who experience stomach discomfort, allicin-rich supplements offer a convenient alternative.
