Can cold, cough home remedies cure symptoms in one use?
Claims that a single-use home remedy of garlic, onion, lemon, and honey cures viral infections lack scientific support. These ingredients may ease symptoms but don’t treat the virus. The immune system requires time—usually 7–10 days—to clear a cold. Colds need time and proper care—not just home hacks. See a doctor if symptoms linger or worsen.
