Onion peel tea calms sleep and makes the skin healthy and shiny
So-called “Zero Waste Cooking” has become increasingly popular in recent years. People are looking for numerous alternatives to using fruit and vegetable peels (which are otherwise thrown away). Onion peel is also one of the alternatives. Onion peel is rich in vitamin A (which improves vision). It is rich in vitamins C and E, so it is great for skin care.
Onions contain quercetin and high levels of anthocyanins (beneficial pigments that have anti-inflammatory and antimicrobial effects). That’s why they make the skin brighter. Onion skin is low in calories (which is another benefit).
Onion skin tea – after peeling the onion – take the discarded skins and boil in water for a few minutes. Strain the water and drink the tea. Drinking tea is relaxing. Tryptophan from the husk can contribute to better quality sleep. Combine the husks with other relaxing herbal teas (for example, chamomile) to have quality sleep and prevent insomnia.
