Safe Ways to Use Boiled Eggshells

If you’d like to take advantage of the natural benefits of eggshells, here are some safe, practical methods:

For a calcium boost:

Rinse eggshells thoroughly to remove residue.

Boil for 10 minutes to sterilize.

Dry completely (in sunlight or an oven).

Grind into a fine powder using a blender.

Store in a clean jar and use small amounts (½ teaspoon per day) in smoothies or soups.

For plants:

Boil crushed eggshells in water for 10–15 minutes.

Let the mixture cool, strain it, and use it to water your plants.
This provides calcium and helps balance soil acidity.
