Garlic and Immune Health: What Science Says About Its Natural Antibacterial Properties

You know garlic as the bold flavor behind pasta sauces, roasted veggies, and stir-fries.
But did you know it’s also been used for thousands of years as a natural remedy?

From ancient Egypt to traditional Chinese medicine, garlic (Allium sativum) has been valued not just for taste — but for its potential to support wellness, especially when it comes to fighting infections.

Modern science has begun to explore what ancient healers long believed:
👉 Garlic contains compounds with antibacterial, antiviral, and antifungal activity.

Let’s dive into what research really says about garlic — so you can enjoy its benefits wisely, safely, and realistically.

Because real health isn’t about miracle foods.
It’s about smart choices backed by nature and science.

🔬 What Makes Garlic So Special?
The magic starts when you crush, chop, or chew raw garlic.

That pungent smell? It’s allicin — a sulfur-containing compound formed when the enzyme alliinase converts alliin into allicin.


Allicin
Most studied for antimicrobial effects (bacteria, viruses, fungi)

Ajoene
Shows antifungal and anti-biofilm properties

Sulfur compounds
Support antioxidant and immune-modulating functions

📌 These effects are strongest in fresh, raw garlic — cooking reduces allicin levels.
