Introduction

Garlic (Allium sativum) is one of the most powerful medicinal foods known to humanity. Used for over 5,000 years across Ayurveda, Traditional Chinese Medicine, and Mediterranean healing systems, garlic is prized for its ability to protect the heart, fight infections, purify the blood, and extend longevity.

Modern science confirms garlic’s role in lowering blood pressure, reducing cholesterol, boosting immunity, preventing infections, and protecting against chronic diseases.

Why Garlic Is Called the “Natural Antibiotic”

• Broad-spectrum antibacterial, antiviral & antifungal
• Supports heart & blood vessel health
• Reduces blood pressure & cholesterol
• Enhances immune defense
• Improves circulation & detoxification
• Associated with longevity & disease prevention

The Science: How Garlic Works in the Body

Garlic’s medicinal power comes from sulfur-containing compounds:

• Allicin – potent antimicrobial & heart-protective compound
• Ajoene – anti-clotting & circulation support
• Diallyl sulfides – detox & antioxidant effects
• S-allyl cysteine – stable compound in aged garlic

When garlic is crushed or chopped, allicin is formed — triggering powerful biological activity that protects blood vessels, immune cells, and detox pathways.
