Boiling eggshells has gained attention as a natural health remedy, but the truth is it doesn’t cure or prevent disease. Eggshells are about 95% calcium carbonate, and boiling them kills bacteria like Salmonella while releasing small amounts of calcium into the water.
Though not medicinal, properly boiled, dried, and ground eggshells can serve as a natural calcium supplement, supporting bone and muscle health. Eggshell water also benefits plants, helping them grow stronger and produce more nutritious food—indirectly supporting human health.
However, myths that it cures arthritis, diabetes, or detoxifies the body are false. Always sterilize shells, grind finely, and consult a doctor before consumption. Used safely, eggshells offer sustainable, eco-friendly health and gardening benefits.
