It is a common habit to toss onion skins into the compost, but they are actually a concentrated source of several powerful plant compounds. When boiled, these outer layers release a deep amber infusion that has been used in traditional wellness practices for centuries.
The Science Behind the Skins

The reason onion skins are so potent is that they contain higher concentrations of certain antioxidants than the onion flesh itself.
- Quercetin Powerhouse: Onion skins are exceptionally rich in quercetin, a flavonoid known for its potent antioxidant and anti-inflammatory properties. It helps the body manage oxidative stress and supports overall cellular health.
- Cardiovascular Support: Regular intake of these plant compounds is often linked to supporting healthy blood pressure and promoting better circulation.
- Skin and Hair Health: The sulfur compounds and vitamins in the skins can be beneficial for soothing skin irritations or adding a natural, golden luster to hair when used as a topical rinse.
Restorative Onion Skin Infusion
This infusion is best made with the dry, papery skins of red or yellow onions. Ensure they are organic to avoid any concentrated pesticide residue on the outer layers.
Ingredients
- 1 cup of clean, dry onion skins (from approximately 2โ3 onions)
- 3 cups of filtered water
- 1 slice of fresh ginger (optional, for flavor and digestion)
Instructions
- Cleanse: Thoroughly rinse the dry onion skins in a colander to remove any dust or dirt.
- Boil: Place the skins and the water into a stainless steel pot. Bring the mixture to a rolling boil.
- Simmer: Reduce the heat to low and let the skins simmer for about 15 to 20 minutes. The water will turn a deep, rich brown or burgundy color.
- Strain: Use a fine-mesh strainer to remove the skins, collecting the liquid in a glass jar or teapot.
- Serve: Drink the infusion warm. Since the flavor is quite earthy and slightly bitter, many prefer to add a squeeze of lemon to brighten the taste.
Tip: You can also use this concentrated liquid as a flavorful base for vegetable stocks, soups, or stews to add nutritional depth and a rich color to your cooking.
