For generations, people have found simple, practical uses for everyday ingredients — and eggshells are no exception. Recently, boiling eggshells has gained attention online, with claims that it can “boost health” or even “cure disease.” While these claims are not scientifically proven, boiling eggshells does have genuine benefits when used safely and responsibly.
Eggshells are made up of calcium carbonate and trace minerals like magnesium and phosphorus. Boiling helps sterilize them by killing bacteria and releasing small amounts of calcium into the water. This process makes them safe to handle and reuse — though it’s important to remember that eggshell water is not a medical treatment. However, ground, sterilized eggshells can serve as a natural source of calcium when added in moderation to foods like smoothies or soups. Always consult a healthcare professional before trying any homemade supplement.
Beyond health, boiled or crushed eggshells can work wonders for plants. The calcium helps strengthen soil and supports healthy root growth. Simply add crushed shells to compost or pour cooled “eggshell water” on plants for a gentle mineral boost. This simple habit also reduces kitchen waste, giving eggshells a second purpose while promoting sustainability.
The bottom line is that boiling eggshells won’t cure disease, but it’s an eco-friendly practice that benefits both your home and garden. By using them wisely, you turn something often discarded into a natural, useful resource — proof that small steps toward mindful living can make a big difference.
