When we think of natural remedies for colds, ingredients like ginger, honey, and lemon usually come to mind. However, one lesser-known yet surprisingly effective remedy has been used in traditional medicine for generations: onion peel tea.
Yes, the dry, papery skin of an onion, the part most of us toss away, actually holds a wealth of beneficial compounds that can help relieve cold symptoms. But how does it work, and is it really effective? Let’s explore the science and tradition behind this unusual yet powerful remedy.

Why Onion Peel Tea Works
While the onion itself is well-known for its immune-boosting properties, the peel is often overlooked. But it is actually the most nutrient-dense part of the onion! It contains:
Quercetin: A powerful antioxidant with anti-inflammatory and antihistamine properties. It helps reduce congestion, ease coughs, and support the immune system.
Flavonoids: These compounds help combat viruses, making them useful against colds.
Sulfur compounds: Known for their antimicrobial properties, they may help fight infections.
These components work together to help reduce inflammation, ease breathing, and support the body’s natural defenses.
How to Make Onion Peel Tea
You’ll need:
Dry outer peels from organic onions (red or yellow)
1–2 cups of boiling water
(Optional) Honey and lemon for taste
Instructions:
1. Wash the peels to remove any dirt or pesticides.
2. Boil water and add the peels.
3. Let them steep for about 10–15 minutes.
4. Strain and drink warm.
Since onion peels have a slightly bitter, earthy taste, adding honey or lemon can make the tea more enjoyable.
Does Science Support Onion Peel Tea?
While there aren’t many direct studies on onion peel tea specifically, research confirms that quercetin and flavonoids, abundant in onion skins, help reduce inflammation and boost immunity. Some studies even suggest that quercetin can help block viruses from entering cells, making it a potentially valuable natural defense.
Many traditional medicine practices across the world, including Ayurveda and European folk remedies, have long used onion peel tea for coughs, sore throats, and congestion.
How Often Should You Drink It?
For best results, drink 1–2 cups a day at the first sign of a cold. Since onion peel tea is natural and caffeine-free, it can be consumed regularly as part of an immune-boosting routine.
Final Thoughts: A Hidden Gem in Your Kitchen
Onion peel tea might not be the first remedy that comes to mind for colds, but its rich antioxidant and antiviral properties make it a simple, affordable, and effective option. If you’re open to natural healing methods, it’s worth giving this grandma-approved remedy a try!
