Onions as a Natural Cleanser
Onions have long been used in traditional medicine for their potent purifying properties. Here’s how they help detox the body:
- Purify the Blood: Red onions are rich in phosphoric acid, which may help eliminate toxins from the blood. This contributes to improved circulation, clearer skin, and even reduced fatigue.
- Cleanse the Skin: Thanks to their natural antibacterial and sulfur compounds, onions have been used in folk remedies to treat acne, blemishes, and irritation. A dab of raw onion juice can act as a natural antiseptic.
- Kill Bacteria: Onions have strong antimicrobial properties, capable of eliminating harmful bacteria internally and externally. This makes them a valuable support for both immune and skin health.
The Red Onion Thyroid Remedy
One of the most fascinating alternative uses of red onions comes from Dr. Igor Knjazkin, a physician from St. Petersburg, who developed a simple yet powerful routine aimed at supporting thyroid function.

How to Use Red Onions for Thyroid Support:
Before bed, slice a fresh red onion in half.
Let the juice start to release.
Gently massage your neck—specifically the thyroid area—with the cut side of the onion.
Don’t wash off the juice. Leave it on overnight.
For added detox, place a thin onion slice in your socks while you sleep. This is a traditional remedy believed to pull toxins through the soles of your feet.
Why red onions? They’re especially rich in sulfur compounds, quercetin, and antioxidants—all of which are beneficial for inflammation and hormone regulation.
Other Science-Backed Health Benefits of Red Onions
Red onions are loaded with compounds that offer full-body benefits:
- Quercetin: A flavonoid with anti-inflammatory and antihistamine effects. It helps lower blood pressure, boost the immune system, and combat free radicals.
- Chromium: A trace mineral that helps regulate blood sugar levels.
- Vitamin C: Essential for immune function, collagen production, and skin health.
- Prebiotics: Onions are rich in inulin, a prebiotic fiber that feeds good gut bacteria, promoting digestive and immune health.
Raw Onions and Heart Health
Eating raw onions (in moderation) has been linked to:
- Lower cholesterol levels
- Reduced risk of blood clots
- Improved heart function
- Decreased risk of certain chronic diseases
- They also support liver detoxification and help the body eliminate carcinogens more efficiently.
