Instructions

Ingredients

Onion Syrup

Onion: 1 medium (yellow or red), thinly sliced

Raw honey: enough to fully cover the onion slices (about 1/2 to 1 cup)

Step-by-Step

Syrup

Layer: In a clean glass jar, alternate layers of thinly sliced onion and honey until the jar is full, making sure the onion is completely submerged.

Steep: Seal the jar and let it sit at room temperature for 6 to 24 hours (overnight is traditional) — the onion will release its juices into the honey.

Strain: Strain out the onion pieces, keeping the golden liquid syrup.

Store and use: Store the syrup in the refrigerator. Take 1 to 2 teaspoons as needed for cough relief.

Onion Sock / Room Method

Cut a raw onion in half or into quarters.

Place the cut onion in a clean sock, or simply set it cut-side up in a small dish in the sick person's bedroom overnight.

Discard the onion in the morning — it is not eaten in this variant.

Tips

Honey caution: not suitable for infants under 1 year old.

The "sock/room" method is a folk belief (the onion is thought to "absorb" germs); it is not medically supported the way the syrup's antibacterial onion-honey combination is.

Add a few slices of fresh ginger or garlic to the syrup jar for extra traditional cold-fighting power.

Traditional logic

Pungent sulfur compounds believed to loosen mucus; cut onion believed to 'absorb' germs

Background & history

Documented in 19th-century Western medical guides alongside garlic syrup. The 'absorbing germs' belief circulated widely in Depression-era American households, especially during flu outbreaks like 1918.

This is a historical and cultural reference, not medical advice. Many of these remedies have never been scientifically validated, and folk reasoning (humoral theory, “hot/cold” classifications, spiritual causation) reflects older explanatory traditions rather than modern medicine. Ratings reflect community opinion, not clinical evidence.
