Generations of home remedies claim that boiling eggshells can “cure disease” or even strengthen the immune system — but science says otherwise. While boiling does sterilize the shells and release trace amounts of calcium into the water, there’s no evidence that “eggshell tea” can prevent or heal illness. What it can do is offer a sustainable way to reuse waste, add nutrients to your diet, and even help your garden thrive.
When prepared safely, ground eggshell powder can provide a small boost of calcium for bone health, and boiled shell water can enrich your plants with vital minerals. But the myth stops there — it’s not a cure, not a detox, and definitely not a replacement for real medicine. The real benefit lies in simplicity: turning something you’d throw away into something that nourishes, recycles, and supports a more mindful way of living.
