A Complete Solution-Oriented Guide to Using Garlic to Fight Sinus Infections, Reduce Congestion, and Support Natural Immune Defense
Sinusitis is one of the most common and frustrating respiratory conditions, affecting millions of people every year. Facial pressure, blocked nasal passages, thick mucus, headaches, fatigue, and impaired smell can persist for weeks or even months, especially when infections fail to fully resolve.
