✔ 3 proven DIY cough syrup recipes (including a fast-acting honey-based version)
✔ The science behind each ingredient (with clinical studies)
✔ Expert tips for maximum effectiveness
✔ Safety precautions (for kids, pregnant women, etc.)

Why Natural Cough Syrups Work Better Than Store-Bought

Commercial cough syrups often contain:

❌ Dextromethorphan (DMX) – Can cause dizziness and nausea (FDA warnings)
❌ Artificial dyes – Linked to hyperactivity in children (Lancet 2007)
❌ High fructose corn syrup – Worsens inflammation

Natural alternatives, on the other hand:

✅ Soothe throat irritation (honey, marshmallow root)
✅ Thin mucus (ginger, thyme)
✅ Fight infection (garlic, oregano oil)

Dr. Josh Axe, DNM and author of Eat Dirt, explains:

"Homemade cough syrups use whole-food ingredients that not only suppress coughs but also support immune function—something drugstore syrups don’t do."
