Purple Onion Skins

Just like garlic skins, onion skins have some unique uses. They’ve even been touted as the new “superfood!”

After reading our select list, if you’re looking for ways to get your hands on onion skins, just collect them with a few onions at your local store. They’re always in the bin with the onions.

1) Throw them in soups and slow cookers: Over 500,000 tons of onion waste is thrown out each year in the European Union and this bulb, including all its skin, is nutritious! Its full of fiber and phenolic compounds which help to prevent coronary disease.

2) Use skins as a dye for wool.

3) Onion skins are known to help cure leg cramps. Boil the skins in water for 10-20 minutes, making an infusion. Drain the skins from the water and drink it as tea before bed. It might take a week or so to take full effect.

4) Throw them in your compost heap.

5) Onion skins make a great hair dye, turning it a beautiful golden brown. Oh, and did you know onions promote hair growth?

6) Dye your Easter eggs a beautiful purple color with onion skins. This recipe shows you how to make pretty imprints, too.

7) Life Hacker suggests you hold on to the onion skin while chopping onions to protect your fingers from your knife. You have to see the picture to get it. Great hack! Then throw the skins in your freezer jar for future soup stock.

8) Dried and ground onion skin as a replacement (small percentage) for wheat flour ups the antioxidant content in bread! Read about the ground-breaking study and give it a try.

    Your headings (scattered here & there in the trashbackwards dotcom page) are readable as they are in high-contrast black type. All of the remaining text that’s posted in lighter-value, gray font misses the boat. Urge you to consider using user-friendly black, high contrast type and font, thanks. Your readers will appreciate it! (The internet and websites were designed as a visual communications media. Yet the current very trendy graphic design style as used in websites and also in hard-copy publications – such as are in American art museums – whose very business is visual communications – belies the fact that adults ages 20’s through 90’s all complain about needlessly light-value type and about thin, tiny type. Cheers) .

    I ground my yellow onion skins in a coffee grinder and put it in capsules size O and take one a day with my other herb vitamins. I am 73 and no meds but the ones I make from my yard, woods and my gardens.
