Onion peel water is an infusion made by steeping or simmering onion skins in water. It is often promoted as a home remedy, but there is not good evidence that drinking it treats illness or provides a special health benefit.
Rinse clean, dry onion skins well, simmer them in water, then strain the liquid. Avoid skins that are moldy, damp, or visibly dirty. Let the infusion cool before drinking, and make only as much as you plan to use soon.
No, onion peel water does not cause weight loss by itself. Unsweetened, it can be a low-energy drink, but there is no reliable evidence that it burns fat or speeds up metabolism. Adding sugar or honey increases its energy content.
There is no reliable evidence that drinking or applying onion peel water makes hair grow or prevents hair loss. Some people use it as a rinse, but it may irritate sensitive skin; stop using it if you notice itching or burning.
Yes, onion peel water can be used as a natural dye bath, especially when made with plenty of skins. It usually gives fabric a yellow, amber, or brown tint, though the final shade varies with the fabric and dyeing method.
No, onion peel water has not been shown to cure a cough or cold. A warm drink may feel soothing, but it does not treat the infection. Seek medical care for breathing trouble, severe symptoms, or a cough that does not improve.
There is no established daily amount or proven need to drink onion peel water every day. Treat it as an occasional infusion rather than a supplement, and stop if it causes stomach discomfort or another unwanted reaction.
Safety data for drinking onion peel water during pregnancy are limited. Onion used in ordinary cooking is different from a concentrated peel infusion; ask your pregnancy care professional before making the infusion a regular drink.
Keep onion peel water in a clean, covered container in the refrigerator and use it promptly rather than storing it for long periods. Discard it if its smell, appearance, or taste changes, and do not leave it sitting at room temperature.
Onion peel water can taste bitter or astringent when the skins are simmered too long or used in a large amount. Rinse the skins, use a lighter infusion, and strain it as soon as the water has taken on color.

Onion peel water is made by steeping or briefly simmering the dry outer skins of onions in water. The skins tint the liquid amber or reddish brown, depending on the onion, and give it a mild, earthy, slightly onion-like taste. In many kitchens, onion skins are more often saved to add colour and savoury flavour to stocks; the strained water can also be sipped warm like an herbal infusion.
It is very light, with 2 calories per 100 g. If you make it at home, wash the skins thoroughly and use sound, clean onions. Steep briefly for a gentler flavour, or add a little lemon before serving if you prefer a brighter taste.
Low
How many vitamins, minerals and how much fiber this food carries per calorie. A high score means a lot of nutrition for few calories.
Medium
An EatBetter score computed from fiber, protein and calorie density. A high score means staying full longer on the same calories.
Both scores are calculated per 100 g and do not change with the selected portion. The satiety score is EatBetter's own calculation, not a clinical measure.
