Women in ancient times knew many seemingly simple remedies, but with an effectiveness that sparks the interest of researchers today. One of these forgotten remedies is onion peel infusion, a simple yet extremely valuable preparation for lymphatic drainage, circulation, and inflammation of the legs. In households of the past, peels were not discarded but were boiled and used either internally (as a weak infusion) or externally (for local baths). The infusion was considered a reliable remedy for heavy, swollen, painful legs, especially after a day of intense work or during water retention. Today, research confirms that these peels contain active compounds with anti-inflammatory and diuretic action.
Detailed Benefits of Onion Peels for Swollen and Painful Feet
1. Reduces Water Retention and Peripheral Edema
Onion peels contain quercetin, a flavonoid with natural diuretic effects that supports the elimination of excess fluids from tissues. Women used the infusion for local baths on their legs, and the effect was quickly noticeable—the swelling decreased and the feeling of heaviness subsided. This effect is due to quercetin’s ability to improve kidney function and the lymphatic system. Additionally, by reducing sodium and water retention, circulation improves. Thus, local baths with onion peel infusion can be a real support for individuals with poor venous circulation.
2. Combats Local Inflammation and Joint Pain
Modern studies confirm the anti-inflammatory properties of onion peels, due to antioxidants such as kaempferol and quercetin. These substances reduce joint and muscle inflammation, especially in the case of tired or painful legs. Women applied warm baths with this infusion and massaged their legs after soaking to relieve pain. The results were often comparable to the effects of herbal ointments. The analgesic effect is explained by the reduction of prostaglandin synthesis—substances that cause inflammation in the body.
3. Stimulates Peripheral Circulation
Onion peels can have a mild vasodilatory effect due to their flavonoid content, which supports the health of blood vessels. By applying warm local baths, capillaries dilate, promoting tissue oxygenation. This effect is especially useful for women with poor circulation or those who stand for long periods. Improved blood flow reduces pressure in the veins and alleviates pressure on the joints. It also helps prevent varicose veins and chronic fatigue in the lower limbs.
4. Local Detoxification and Stimulation of Lymphatic Drainage
Quercetin from the peels also has a lymphatic stimulating effect, promoting the elimination of accumulated toxins in the intercellular spaces. This helps deeply cleanse the tissues, being particularly useful for individuals facing toxin retention, inflammation, or autoimmune reactions. Traditionally, the infusion was used in 7-10 day courses, alongside detoxifying teas. This combination contributed to a gentle yet effective detoxification. Today, these baths can be integrated into natural body cleansing regimens.
5. Soothes Irritated Skin and Improves the Appearance of Legs
Onion peel infusion also has beneficial effects on the skin, due to its antiseptic and antibacterial compounds. Dry, flaky, or irritated skin is often associated with circulatory problems, and baths in this infusion hydrate and soothe it. In some areas of Moldova and Bukovina, women used these baths to combat fungal infections or skin irritations. After several uses, the skin became smoother, and the legs took on a healthier appearance.
Traditional Recipe: Onion Peel Infusion
Ingredients:
-
Dried peels from 4-5 onions (preferably red, but yellow can also be used)
-
1 liter of water
Preparation:
-
Wash the onion peels well, especially if they come from chemically treated sources.
-
Bring the water to a boil.
-
When boiling, add the onion peels and simmer for 10-12 minutes on low heat.
-
Turn off the heat and let it steep for another 10 minutes, covered.
-
Strain the liquid and use it immediately for local baths.
Usage Instructions
-
Pour the warm liquid into a basin and soak your feet for 15-20 minutes.
-
Repeat daily for 7-10 days in case of swollen feet, pain, or a feeling of heaviness.
-
A compress with this infusion can also be applied to painful or inflamed areas.
-
Internally, a weak infusion (1 tablespoon of dried peels in 250 ml of water), 1-2 cups per day, can be consumed only under the guidance of a specialist.
Relevant Studies
A study published in the Journal of Nutrition demonstrated that quercetin, abundant in onion peel, has a significant effect on reducing inflammation and oxidative stress at the cellular level. This translates to reduced pain and fluid retention in individuals with venous insufficiency.
In another study conducted by the University of Bonn, it was found that onion peel extract reduces inflammatory markers such as TNF-alpha and IL-6, supporting its use in complementary therapies for rheumatism and edema.
An experiment published in Planta Medica confirmed that the aqueous extract from onion peels has diuretic properties comparable to those of established medicinal plants, such as nettle or horsetail.
A Japanese study showed that local baths with infusions rich in quercetin improve microcirculation and have a calming effect on tired muscles, making this infusion a practical method for alleviating discomfort in the lower limbs.
Researchers at the University of Lodz highlighted the antioxidant effects of onion peel extracts, supporting their use in protecting capillaries and preventing vascular aging.
It has also been shown that these compounds stimulate lymphatic function and reduce chronic inflammation in the limbs, according to a study published in Oxidative Medicine and Cellular Longevity.
In vitro studies conducted at the University of Vienna showed that infusions from onion peels have antifungal and antibacterial effects, which explains their traditional use in cases of foot mycoses.
A report published in the European Journal of Clinical Nutrition indicated that supplementation with quercetin led to reduced edema in patients with metabolic syndrome, suggesting a systemic effect of the compound found in onion peel infusion.
Another study, published in 2020 in Frontiers in Pharmacology, evaluated the anti-inflammatory effect of Allium cepa extracts and concluded that they may be useful in external therapies for joint and muscle pain.
Researchers from the Department of Pharmacognosy, Cairo University supported the use of onion peels in traditional external formulations due to their rich flavonoid content, which plays an important role in restoring peripheral microcirculation.
Contraindications
-
Internal use is not recommended without medical advice, especially in cases of kidney disorders, pregnancy, or breastfeeding.
-
Pregnant women should avoid prolonged hot baths, as they may excessively stimulate circulation.
-
Individuals allergic to onions should also avoid the peels, even externally.
-
It is recommended to test on a small area of skin before use, especially for those with dermatitis.
