11 Reasons Why You Should Never Throw Away Eggshells

Egg’s shell is natural source of minerals and contains 90% calcium. Calcium is easily absorbed by our body because its chemical composition is almost identical to human’s teeth and bones.

If consumed in larger amounts, calcium will not only get rid of lack of calcium-symptoms, but it will also prevent osteoporosis’ development, stimulate the bone narrow in producing blood cells and help when it comes to treating high cholesterol levels and high blood pressure.

Egg shell also contains iron, zinc, copper, manganese, fluorine, phosphorus, chromium and molybdenum. Therefore, many experts recommend shell eggs as a natural and very effective calcium supplement.

It is recommended to enter 1.5 to 3 grams of crushed shells a day.

Here are several ideas on how to use egg shell and what to use them for:

1. Make Your Coffee More Drinkable
Do you hate how bitter your morning cup of coffee is? Here are two pieces of advice: read our coffee primer, and add crushed up eggshells to the grounds when you brew your cuppa.

I know, I know: it sounds weird and gross. But the eggshells serve to clarify the coffee, which helps reduce the bitter taste (and they add no taste of their own). However, make sure that you’re using eggshells that have been washed (note: in America, all eggs are washed before being sold).

2. Feed Your Compost Pile
If you have a compost pile, you should be sending almost all of your rogue eggshells that way. The shells will decompose quickly and naturally, and when they do they’ll add lots of calcium to your pile. It’s a common misconception that you can’t put eggshells in compost piles because the shell is too hard, but this is far from the truth.

It’s also a common misconception that unwashed eggshells will contaminate a compost pile with salmonella, or that they won’t degrade because of the egg proteins. In actuality, there’s not enough egg left on the inside of the shells to impact your compost pile, and the heat from the compost will kill any potential salmonella bacteria.

Eggshells are sharp. As such, you would think that rubbing them on your skin would irritate the skin, not heal it. And while it’s true that a handful of eggshells rubbed directly on your arm would not feel good, a treatment made of shells and apple cider vinegar can help treat inflamed or cut skin.

Simply leave some crushed-up eggshells in a bowl with vinegar until the shells dissolve (it will take a day or two), and then rub it on your skin and start feeling better! Eggshells are high in calcium, and calcium is a time-honored remedy for skin problems from acne to rashes.

4. Keep Your Garden Happy
Eggshells serve double duty in a garden. If you mix them into the soil, they’ll have the same impact that they do in your compost: they’ll decompose and feed valuable nutrients into the soil, which in turn will make your plants happy. And if you sprinkle some crunchy eggshells on the surface of your soil, it will repel slugs and snails, who won’t slide over the sharp edges of the shell.

5. Keep Your Clothes from Greying
This sounds bizarre, but it totally works. If you add some eggshells and lemon slices to a cheesecloth bag (or any other semi-permeable laundry safe bag), and then add it to your load of laundry, your clothes will hold their color better. The shells maintain the color in your clothes by preventing the soap deposit responsible for turning clothes grey and dirty.

6. Make a Scouring Pad
Don’t have a scouring pad? Or have a scouring pad that’s still got crud in it from the last dish you washed? Don’t worry! Crush up some eggshells and drizzle soapy water on them. Then add the shells and soap to a sponge or dish towel, and scrub your pots and pans clean of any pesky food bits. The shells are just sharp enough to be abrasive, but not so sharp that they’ll do any damage to your dishes.

7. Make Homemade Chalk
Making homemade chalk is not only cool, but incredibly easy. Just mix a teaspoon of flour with a teaspoon of hot water, then add a tablespoon of crushed eggshells and some food coloring. Shape or mold the chalk, let it dry for a few days, and enjoy an incredibly fun use for leftover eggshells.

8. Prank Your Friends
With just a little work, you can bake a cake inside a mostly whole eggshell. All you need to do is cut a small whole in an egg, empty out the contents, fill it with cake dough, and bake it.The eggshell cakes will look and feel just like hard-boiled eggs from the outside, making for a hilarious moment when someone reaches for what they think is a hard boiled snack (leave them upside down, so the hole is covered, and they’ll never notice).

9. Strengthening the organism and cleansing the blood
Wash 5 egg shells, crush them good and put them in 3 liters of water. Keep this mixture in the refrigerator for 7 days before using it as a drinking water. Drink two to three glasses of this mixture a day. You can add lemon juice if you want to.

10. Thyroid gland
Take 8 egg shells, wash them good and crush them even better. Pour juice of 2 lemons over the crushed egg shells and leave in refrigerator for several days. When shell will soften, strain the liquid and mix it with 1 liter of rakia and 1 kg of honey. Let this mixture stand still for 7 days before using it. Consume one teaspoon two to four times per day after meals.

11. Gastritis, ulcer
Crush some egg shells. Pick some using the tip of the knife. This amount of egg shells will be enough for treating these diseases. Mix the crushed egg shells with 2 tablespoons of lemon juice. When shells will soften, add one deciliter of hot milk. Consume this mixture 2 times a day – on an empty stomach in the morning and before bedtime.
