That sounds like one of those viral chain-style messages.
Garlic does have some real health benefits—its active compound, allicin, has antibacterial and antifungal properties, and it may support the immune system. But calling it a “natural antibiotic that wipes out infections” is an exaggeration. It’s not a substitute for proper medical treatment, especially for serious infections.
As for the “say something to keep receiving recipes” part—that’s just engagement bait. You don’t actually need to comment to keep seeing content.
If you’re interested, I can share some legit, evidence-based ways garlic can be used for health—or some good recipes that use it.
