Why boil eggshells?

 

Boil eggshells to say goodbye to all evils… The idea is seductive, almost magical. At a time when we are looking for natural, economical and sustainable solutions to take care of ourselves, this kind of tip is circulating a lot. But what is really behind this practice? Spoiler: there is some truth… and a lot to be nuanced.

What happens to shells when boiled

The vast majority of eggshells are made up of calcium carbonate, a mineral that is essential to the body. When boiled, two important things happen. First, the heat eliminates unwanted bacteria, making the shells safer to handle. Then, a small part of the minerals can pass into the cooking water.

As a result, the shells become cleaner and potentially reusable. But be careful, this does not turn them into a miracle cure.

Can you really “cure” something with eggshells?

Let’s be clear: no, boiled eggshells do not cure diseases. They do not fight viruses, infections or chronic disorders. On the other hand, they can be part of a global well-being approach, provided they are used with common sense.

Where they are interesting is for their mineral content, especially calcium, a nutrient that is essential for the proper functioning of the body.

A natural source of calcium… Handle with care

Calcium plays a key role in the strength of bones and teeth, but also in muscle contraction and general balance. Some people are looking for natural alternatives to supplement their intake.

Carefully cleaned eggshells, boiled for at least 10 minutes, dried and then ground into a very fine powder can be used in minute quantities. However, it remains an artisanal supplement, which does not replace a balanced diet or professional advice.

The key word here: absolute caution. Rough preparation can cause digestive discomfort or inadequate intake. Before any regular consumption, it is essential to seek advice from a health professional.

A smart move to reduce waste

Where eggshells really make a difference is on the ecological side. Reusing them limits waste and gives a second life to what we usually throw away without thinking about it.

For example, the cooking water from eggshells can be diverted for a gentle, minimalist make-up removal. After boiling 2-3 clean eggshells in 1 liter of water for 10 minutes, let cool and then strain. Then use 50 to 100 ml of this warm water on a washable cotton pad to remove impurities from the face, before your usual cleanser.

This water does not replace a classic make-up remover, but it can serve as a gentle first step, especially for the complexion, while enhancing everyday waste.

It’s a small, simple action, but it’s part of a more responsible and conscious approach to everyday life. And taking care of your environment is also an indirect way of taking care of yourself.

The well-known secret of planters

Do you have a green thumb? Good news: the water from cooking eggshells is appreciated by many plants. Calcium helps to strengthen their cell walls and improve soil structure.

Stronger plants often result in better quality fruits and vegetables. And a more varied diet rich in fresh products naturally contributes to a better balance on a daily basis.

The myths that circulate (and why to be wary of them)

On the Internet, we can read that boiled eggshells:

• “detoxify” the body,
• replace certain treatments,
• or relieve specific disorders.

These claims are not based on any serious evidence. The shells contain minerals, yes, but they are not a substitute for medical follow-up or an adapted lifestyle.

How to use them safely

If you are tempted by the idea, here are reasonable and safe uses:

• For the garden: boil crushed shells, let them cool, filter and use the water to water your plants.
• For domestic use: choose non-food applications if you have the slightest doubt about the preparation.

What you need to remember

Boiled eggshells aren’t a silver bullet, but they can become a smart ally to reduce waste, feed your plants, and rethink your habits.

Because when it comes to well-being, it’s often the simple gestures, repeated with common sense, that make all the difference.
