With their distinct and irresistible flavor, onions have long been a culinary favorite in kitchens worldwide. The versatile veggie adds depth and character to everything from soups and stews to stir-fries and sauces. However, we often overlook one part of the onion that is something of an unsung hero — the onion skins! It turns out they’re a treasure trove of nutrients that deliver powerful health benefits. So before tossing them aside, read on to discover how to tap into the power of these often-overlooked gems. As the saying goes, waste not, want not!
What makes onion skins so special?
Even more than the flesh of the vegetable, onion skins are densely packed with nutrients. A comprehensive review of studies in Biomedicine & Pharmacotherapy found that onion peels contain a more concentrated amount of the bioactive compound quercetin. This potent antioxidant fights harmful free radicals that can damage the body’s cells.
According to Cameron Rokhsar, MD, professor of dermatology at Mount Sinai Hospital, quercetin has the potential to reduce inflammation, lower “bad” LDL cholesterol, curb high blood pressure, and soothe anxiety and depression. (Click through to find out how onion skins can even boost hair growth!) And while all onion skins contain the beneficial compound, research reveals you’ll find the highest concentrations of quercetin in red onions, followed by chartreuse onions, then yellow onions.
“Onion skins are also loaded with flavonoids and vitamins A, C, and E, which come with greater antioxidant and anti-inflammatory properties than the flesh of the onion,” explains Dr. Rokhsar. In fact, research shows the outer layer of the onion skin alone accounts for 80% of the vegetable’s flavonoid content.
5 ways onion skins improve your health
This humble superfood packs a payload of health perks. Here are five areas where onion skins really shine:
1. They improve your digestion
“Onion skins are rich in fiber, which aids in digestion, and may help control blood sugar levels,” says Anna Chacon, MD. Whole onions contain about 1.9 g of dietary fiber, but a study published in the Journal of Agricultural and Food Chemistry found that the skin of the onion contains the most concentrated amount of dietary fiber — nearly 66% of vegetable’s total dietary fiber content!
Fiber also adds bulk to your stool, promoting regular bowel movements and preventing constipation. A study in The American Journal of Clinical Nutrition found that 66% of adults with chronic constipation increased the frequency of their bowel movements within 4 weeks of upping their fiber intake.
2. They bolster your immune system
“Onion skins contain various beneficial compounds, including antioxidants. These compounds have been associated with potential health benefits, such as reducing oxidative stress and inflammation and supporting immune function,” says Blen Tesfu, MD.
Immune-hampering oxidative stress occurs when there is an imbalance between the production of free radicals, which are the natural byproducts of your metabolism working, and the body’s ability to detoxify these byproducts. A potent antioxidant, the quercetin found in onion skins neutralizes these free radicals and protects immune cells from damage.
In fact, quercetin is so effective that research in the International Journal of General Medicine suggests it can even help speed COVID recovery. Researchers found that COVID patients who took 1,500 mg. of quercetin daily recovered up to seven days faster than those who didn’t take quercetin. And onion skins are a stellar source of quercetin. Research in The Journal of Science of Food and Agriculture found that onions contain three times as much quercetin as broccoli and six times as much quercetin as apples.
3. They lower “bad” LDL cholesterol
The quercetin found in onion skins has a powerful ability to lower harmful LDL cholesterol. “It works by inhibiting the production of cholesterol in the liver and reducing the absorption of cholesterol from the intestines,” explains Trista Best, RD. Proof it works: Research in the British Journal of Nutrition found quercetin noticeably lowered LDL levels within six weeks. (Click through for more natural ways to lower high LDL cholesterol.)
4. They speed weight loss
Hoping to shed a few extra pounds that have snuck on recently? Onion skins to the rescue! A study in Nutrition Research and Practice found that folks who did nothing other than supplement with onion peel extract daily effortlessly shed 2 lbs. of weight, 1 lb. of fat and 1 inch from their waistlines within 12 weeks. Researchers found onion skins’ quercetin increased resting energy expenditure, or how many calories your body burns while at rest.
5. They tame allergies
Perhaps one of the most powerful benefits of onion skins is their ability to tame both indoor and outdoor allergy flare ups. It comes as no surprise that the credit goes to onion skins’ quercetin. A study in the European Review for Medical and Pharmacological Sciences found that supplementing with quercetin, which has a natural antihistamine action, eases allergy symptoms such as sneezing, runny nose and eye irritation by 50%.
While folks in the study took 100 mg. of quercetin twice daily, you can get the benefits simply by upping your onion intake. In fact, onions are so high in quercetin that a study in Food & Function found consuming a bowl of soup made from red onions boosts your quercetin levels as much as a 544 mg. quercetin supplement does.
The easiest ways to use onion skins
Ready to harness the benefits of antioxidant-rich onion skins? It’s easier than you think, thanks to these simple recipes.
Make onion skin broth
Mary Sabat, RDN, shares a basic onion broth recipe you can use in your favorite soups and stews. Or simply sip it warm as a comforting, nutrient-packed tonic!
Ingredients
- Outer skins of 4-5 onions
- 8 cups of water
- 2 to 3 cloves of garlic (optional)
- Salt and pepper to taste
- Rinse the onion skins thoroughly under cold water. Tip: You can save the skins from your regular cooking in a lidded container and refrigerate until you have enough.
- Add the onion skins, water, and garlic to a large pot.
- Bring the mixture to a boil over medium-high heat. Then reduce the heat to low, cover the with a lid, and let it simmer for about 30 to 40 minutes. This allows the flavor from the onion skins to infuse into the broth.
- Remove from heat and strain the broth through a fine mesh strainer or cheesecloth into a container. Discard the solid onion skins and garlic cloves.
- Season the broth with salt and pepper to taste.
As with any homemade broth, you can get creative by adding other vegetable scraps (such as carrot tops or celery leaves) or your favorite herbs and spices to enhance the flavor and nutritional content.
Make onion powder
A sprinkle of onion skin powder gives dishes such as sauces, marinades, salad dressings, or spice rubs a subtle onion flavor (plus a payload of nutrients!). Add as much or as little as you’d like to your favorite dishes until the flavor is just right.
- Collect onion skins from your regular cooking until you have at least one cup. Rinse the onion skins thoroughly under cold water.
- Spread the cleaned onion skins in a single layer on a baking sheet or a wire rack. Allow them to air dry completely for several days. To speed up the drying process, place the skins in a low-temperature oven (around 150°F) for two to three hours or until they become dry and brittle.
- Transfer dried onion skins to a spice grinder, coffee grinder, or a high-powered blender. Pulse or grind the skins until they turn into a fine powder. You may need to grind them in small batches to achieve the desired consistency.
- For a smoother texture, you can pass the powdered onion skins through a fine-mesh sieve to remove any larger particles. This step is optional but can result in a more refined powder.
- Transfer the powdered onion skins to an airtight lidded container. Store it in a cool, dry place away from direct sunlight. Properly stored, onion skin powder can retain its flavor and quality for at least three months.
Make onion skin tea
“Onion tea can also be made out of the onion skin layers to extract some of these antioxidants,” says Cesar Sauza. Click through to our sister site for a simple onion skin tea recipe.

Ask a doctor: ‘Is it ever OK to take someone else’s prescription medication?’
![Ask a doctor: ‘Is it ever OK to take someone else’s prescription medication?’](https://static.foxnews.com/foxnews.com/content/uploads/2024/06/pass-pills.jpg)
Most of us have, at some time or another, asked a friend or family member for some over-the-counter medicine to treat a headache or an upset stomach, as the dosage and directions are fairly universal.
But is the same protocol appropriate when it comes to taking someone else’s prescription medication?
The resounding answer from medical doctors is an emphatic “no.”
MEDICINE CABINET MUST-HAVES: 9 ESSENTIALS EVERY HOUSEHOLD SHOULD HAVE ON HAND
There are specific reasons why.
“Taking someone else’s prescribed medication can be very harmful,” LaTasha Perkins, M.D., a family physician at Medstar Georgetown University Hospital in Washington, D.C., told Fox News Digital.
Doctors agreed that sharing prescription medications with others is a bad idea. (iStock)
“You need to take only your own medicine and not someone else’s, because so much goes into figuring it out.”
Numerous considerations are involved in prescribing medication to a patient, Perkins said — including health status, medical history and blood work — which can be completely different from one person to the next.
Even if you take the same medication as someone else, the other person may be on a different dose of it, the doctor noted.
TRAVELING INTERNATIONALLY? IT COULD BE ILLEGAL TO BRING ALONG THESE MEDICATIONS, ACCORDING TO A PHARMACIST
“A lot of medications also look and sound the same, so you have to take what was specifically prescribed to you,” she cautioned.

Drug interactions present another concern.
“If you’re taking vitamins or any other medication that may interact with a prescription medicine, that should be taken into account when tailoring your prescription,” Perkins said.
Allergies are yet another key consideration, the doctor warned, as some people are allergic to the additives in medications.
“There’s a reason the medication is prescribed — because it’s personalized to each individual based on a variety of health factors,” Perkins said.

The consequences of sharing prescription medication — which is never a good idea — can range from severe allergic reactions to medication interactions and overdosing, one doctor warned. (iStock)
Chad Weston, M.D., a physician with Novant Health Oceanside Family Medicine & Convenient Care – Brunswick in Shallotte, North Carolina, agreed that taking a medication prescribed to a different individual, even for seemingly similar symptoms, can be harmful and have unintended consequences.

“These consequences range from severe allergic reactions to medication interactions and overdosing, causing damage to organs such as the liver and kidneys,” he said in an interview with Fox News Digital.
Instead of seeking symptom relief by taking someone else’s medication, you should see a doctor to get an accurate medical diagnosis and prescription, Weston advised.

In the event that you’re traveling and don’t have your medicine with you, Perkins said the best thing to do is call your doctor.
“If you don’t have your medicine, we can call it into a pharmacy wherever you are,” she said.

“This is why it’s so important to have a family physician,” she said.
“Having a relationship with your doctor can help you navigate situations like this.”
