This Honey Onion Cough Syrup is soothing, sweet, and packed with natural goodness! Thinly sliced onions release their immune-boosting juices into raw honey, creating a golden syrup that calms sore throats and eases coughs. Ready overnight and made with just two ingredients, it’s a simple, time-tested remedy that’s perfect for keeping your family healthy through the cold season.
Key Ingredients
1. Onions
Onions are rich in quercetin and natural compounds that help fight inflammation and support the immune system. When sliced, they release their natural juices, which blend with the honey to create a soothing, medicinal syrup.
2. Raw Honey
Raw honey is naturally antibacterial and anti-inflammatory, coating the throat to calm irritation while providing powerful antioxidants. It also draws out the onion’s juices, transforming them into a sweet, golden syrup.
Step-by-Step Instructions
Step 1. Slice the Onion Peel and thinly slice or dice the onion. The thinner the slices, the faster they’ll release their natural juices into the honey.
Step 2. Layer and Cover with Honey Place the sliced onions in a clean, sanitized glass jar. Pour raw honey over them until they are fully submerged and covered.
Step 3. Let It Steep Seal the jar tightly and let it sit at room temperature for 6–12 hours, or overnight. The honey will draw out the onion’s liquid, creating a sweet, soothing syrup.
Step 4. Strain (Optional) If you prefer a smooth syrup, strain out the onion pieces before storing. Otherwise, leave them in and scoop syrup as needed.
Step 5. Store and Use Transfer the jar to the refrigerator and use within 3 weeks. Take 1–2 teaspoons as needed to soothe coughs and sore throats.
Frequently Asked Questions
Can I use any type of onion?
Yes! Yellow onions are the most common choice, but you can also use white or red onions. Red onions will make the syrup slightly pink and milder in flavor.
Do I have to use raw honey?
Raw honey is best because it retains its natural enzymes and antioxidants, but regular honey will still work and give you a sweet, soothing syrup.
Do I need to refrigerate it?
Yes, after the initial 6-12 hour steep at room temperature, store the syrup in the refrigerator to keep it fresh.
How long does it last?
It’s best used within 3-4 weeks. The honey naturally preserves the mixture, but for maximum freshness and potency, make small batches you can finish in that time.
Can kids take this syrup?
Yes, but only give it to children over 1 year old since honey is not safe for infants under 12 months.
