Best DIY Cough Syrup for Winter Immunity (Natural Cold & Flu Remedy)
Ingredients
- 1 medium onion thinly sliced
- 1 large thumb of ginger sliced
- 1 cinnamon stick
- 1 star anise
- 1 cup raw honey or enough to fully cover the ingredients
- Optional but recommended add-ins:
- 1 –2 garlic cloves
- 1 slice lemon
- ½ tsp turmeric + pinch of black pepper
- 1 small sprig fresh thyme
Instructions
- Prep the ingredients : Thinly slice your onion and ginger. If using garlic, smash it lightly with the back of a knife — this helps release allicin, its natural antimicrobial compound.

- Cover with raw honey : Pour honey over everything until fully submerged.
- Seal and leave to infuse : Close the jar and let it sit at room temperature for 12–24 hours.
- The honey will begin to thin out as the onion releases its juices.
- Use immediately or let it strengthen : You can start using it within a day, but it becomes stronger and more soothing over the next 2–3 days.
